Is it bad that I literally took psle last year, didn't do too badly, but now seeing some of these questions I am mindblown as to how I did it less than a year ago...
@@yono1407 half? u sure? try to understand vectors and higher order questions based on them with 4 weeks prep and note higher order questions with hybrids its so stress that it rivals fighter pilots
I love how you can see her struggling with it, like she's writing down stuff like the average of 7.2e8^i divided by the quadratic formula and multiplied by pythagoras' theorem to figure out if ⅖ is 2% or 20% even though this is a test for 12yr olds
yeah!!! and so many comments are just telling me 'lol this is easy use algebra'. The truth is that the entire paper is meant to be solved WITHOUT algebra. And a lot of time, if you did try using algebra like I did (it was the only way I could see myself solving anything). You'd get stuck. It's a tricky paper >_>
American here: Here we have state mandated testing. In like 7th grade we had to do a series of state run tests and one English reading related prompt gained infamy in our region because the question went something like, "what is the over all meaning of the story" in a very abstract interpretation, it spread throughout the school even to the teachers that not even the writer for the passage knew the answer to that question.
as a 13 year old i can confirm school is bs, and the test in the video is actually easier than it should be (imo; I am 2 years above so I'm not perfectly accurate, but I'm pretty sure I could say the same back then)
@@Ibbys_space imo primary school is necessary, and middle school is needed to socialize some more but once your in high school its kinda eh, at least for English and Math stuff.
@@obsidianflight8065 I'd say that in NZ the first 3 years of highschool are necessary (later 2 are fine, many drop out in 4th year). You get to choose your subjects for the most part, so if you're like "I want to be a builder, why do I need to know chemistry" you can do the math, english, woodworking, metalworking and focus mostly on those (science is required, but it's very basic in early years)
honestly the fact that you can even solve any of this is amazing. i cant even begin to wrap my head around to even understanding any of these questions
For Singapore, they dont teach primary school students algebra so its actually not very natural for them. The question is relatively easy but its not suited for the knowledge that primary school students learn
As someone who got A* for math in PSLE, im glad to say that i am now failing all my Amath papers 🙃 Edit: passed prelim amath paper. REDEMPTION ARC LET'S GO Update since I'm still getting replies lmao. I got B3 for A-Math and A2 for E-Math
the reason the math test for a 12 year old would be a nightmare, is because it's purposefully useless information, you're supposed to overwrite that info by now, so it's fine.
I definitely think that children that young shouldn't be put through exams like this one and I am really not a fan of the way maths is taught in most places around the world. Maths truly is about problem solving and using logic. It's not useless information, maths is used literally everywhere from business to computer science or physics. Even if you don't go to work in a STEM field you're still going to need it in one way or another especially now. Being a better thinker allows you to make better decisions when you encounter new evidence or statistics and for that you need maths.
And on top of that what concepts that we're being 'taught' is nothing compared to what the world of mathematics is And in my experience I would say the subject is pretty ripe with hypothesis such as 3x+1 (check out Veritasium's video) not being solved and many more
@@sergiuszstrzelczyk7984 finally. I feel like the way schools teach math does not represent math at all in its entirety. Its just rote learning and makes people dislike math even more. In university, math is taught in a way that you require understanding so that you are able to write proofs. Edit: forgot to mention, when complex variables was first discovered, it was not used for any applications at all. But as time passed, someone found it was quite useful (for something.. you can google it i forgot what it was lol) and thus it is used in many areas of STEM today such as physics and engineering.
@@sergiuszstrzelczyk7984 as someone who's taking compsci, i don't think i ever had to use math past 3rd grade level, considering the computer does the equation and you just have to use basic mathematical thinking; something an adult can learn within a day or two from scratch
I mean learning how to think logically takes time and the same goes for problem solving. For some people it may be easier but still it takes time to develop an understanding of certain concepts and an ability to think mathematically. If everyone could do this in a day we wouldn't have textbooks or any formal system of education. Not everyone needs complicated maths in their life but it's good to know at least some maths. Btw I'm not sure if you're talking about university or something but mathematics is an intrinsic part of computer science. Discrete mathematics so areas like logic, set theory, combinatorics, graph theory and number theory as well as different areas of maths are important for designing efficient algorithms, analyzing computational complexity etc.
I remember hearing about this test from a Singaporean and being appalled that they would pretty much use this test to ban kids from being a doctor or whatever they wanted so young
I don’t think that’s how it works, but if you f up on this test then it’s somewhat going to affect the future career(Secondary School then College or Polytechnic and the University)
Yeah it's kinda f'ed up. I think a lot of Singaporeans actually don't realise how much your PSLE score can affect your education and career. If you don't do well for PSLE, your secondary school might not even offer pure sciences as a subject you can take, so if you wanted to become a doctor you likely will never make it.
I'm in college right now actively taking a calculus based physics class and I fully admit I probably would've failed that test. You rarely ever use primary school math outside of its fundamental building blocks to learn other maths. Like I can't do fractions, I have to convert to decimal then back if the answer needs to be a fraction.
Learn fractions. I don't know how you can do calculus without understanding them. What do you struggle with (adding them, multiplying them, I'm just confused)?
@@caenir you don't need to know fractions if you're fine using decimals. There may be extra steps involved but everything depends on how much effort you want to put into the problem.
@@caenir well 2/3 is also an approximation, but yeah, I agree they're simple to understand. But they really aren't necessary. Most of the time things can be purely understood and rationalized with a decimal. It's just a matter of preference.
A lot of the problems are just simple algebra. The hardest part I would say is converting the actual problem into an algebra problem. If you can do that, the questions become a lot easier.
@@uttkarshtewari2532 I mean, we started learning algebra at age 12 so it's reasonable, and i think most schools teach problem solving in math class since 4th or 5th grade.
I feel like it's easier for 12 year olds because we've learned all of that stuff recently (at the time of the test) so it's all still there. though that semi circle question is insane (it took me like 10 minutes for the pie chart question)
As a big boi well over 12, and as someone who's somewhat decent at math, that pie chart question was doable for me, but I can't imagine a 12 year old having to think of a solution to that while giving an exam, there's some pretty tough algebra there. And I'm not even going to even begin doing the semicircle question, I don't have the time xD But yeah maybe you're right, maybe it's much easier as a 12 year old cause that's when you're studying this kind of stuff
For the speed distance question, there are some hints to the question. The way they requested you to find Daniel's speed in part a and then the time he started his journey suggested that you shouldn't use Total Distance/total time. a) @12pm, D overtook C. D complete his journey at 2pm while C is 50km away. That suggested that from 12pm to 2pm, C travelled 75x2 = 150km. Since C is 50km away from town Y, that means D travelled 200km from 12 to 2pm. Hence, the average speed of D is 200/2 = 100km/hr. b) Total distance from town x to y = (75x4) + 50 = 350km Since D's average speed is 100km/hr (found in part a), his time taken to complete the entire journey = 350/100 = 3.5 hours Since D complete the journey at 2pm, he starts his journey @ 1030am. *check: if D starts his journey at 1030am, at 12pm, he would have travelled 150km, which is the same amount of distance travelled by C. For such questions, when they say overtake, it literally means they met one another. I always feel that they should phrase this kind of questions better. Ps: i'm a teacher but not at this level.
This was pretty brave of you to put out; and I think it shows exactly why I watch your content. You aren't afraid to poke a little fun at yourself and show your vulnerabilities. It's a rare trait. None of us are perfect. Damn, I would absolutely suck at this test haha
I got flashbacks from the time i entered LGS when I saw those questions, which stands for "Highschool Entrance Exam" (in turkish). I was in 8th grade. The math questions were horribly hard. They had multiple subjects you needed to use for one question, obtuse illustrations, way too hard and lenghty explanations of the images+the questions and some questions had stuff we didn't learn throughout 8th grade, which had most of the material used for the exam questions. They were asking these questions to 13-14 year-olds. I remember almost crying out of stress. Plus 3 wrong questions elliminates one correct answer. So i got 8 questions right, 8 questions wrong and left 4 questions blank. Because of this 3 wrongs-1 elimination method, the system calculated that I got 5.33 questions right. Which is kind of a slap to my face. Anyway. I got 393/500 points and got into top 14% in Turkey. Guess what? Couldn't even get into a good highshool because the most mediocre ones start from top 13%. I had to settle in with an occupational highschool that teaches a lot of redundant lessons, takes up my time 9 hours a day, and teaches me sciences even though i will never use them during the university exams. (You take 2 different kinds of exams in here. Each one has 3 different categories. TYT and AYT. TYT stands for "Basic Competency Test", which has 9-10th grade subjects (including stuff from middle school). AYT stands for "Field Competency Test". In this one, you solve the stuff you learnt in 11th-12th grade. For AYT, you use the things you learnt from the point you chose a field in highschool. 1) One category for maths, turkish literature, biology, physics, chemisty. 2) One category for maths, turkish literature, philosophy-1, geography-1, history-1. (Which is the category i need to solve tp get to the university i need to go in) 3) One category for turkish literature, history-2, geography-2, philosophy-2, maths. (There is a difference between 1 and 2) Instead, i had to choose between being a nurse helper, a midwife helper and a healthcare technician. The system put me in the nurse helper category. Yay.)
also: question 45: 75kmh x 4 hours, 300km, +50km to go, total distance is 350km. Daniel passes 75kmh guy at noon, 75kmh x 2 hours, 150km, 350km total minus 150 gives us 200km, and daniel had to cover 200km in 2 hours (ergo 100km/h), working backwards, 350km/100kmh is 3.5, which means he left 3 and a half hours before 2 aka 10:30
Seeing this title when I first opened UA-cam this morning had me rolling. Edit: I feel like these tests are less about the actual maths and more about your comprehension and reasoning abilities.
I can't call Jolene more succesfull than her classmates because succes is different for every people. For Jolene it can be being succesfull youtuber, but her classmates it can be attending good universities.
A Turkish person here, we also have a similar exam system for 8th graders (12-13-14) called LGS to get a good high school. The exam has on 6 lessons (Math, Science, English, History/Social Studies, Turkish & Religion) and a scoring on 500. (if you get over 400, you're going to a good school! ) However, the questions are as hard as the questions shown here! Some are even harder, especially for math. There are some questions which take up a whole page! I'm currently studying for this exam, and it's very very hard..
3:46 isn't this just basic equality but with weird representations, the graph just makes it look weird say that D stands for a diameter we have 2 segments that are equal in lengths so we can set them equal to each other, the first one consists of 3 Semi circles and 2 gaps with lengths of 12, the other is 2 semi circles with 3 spaces with lengths of 22, 16, 22. 3D + 24 = 2D + 60 subtract (2D + 24) to the whole thing 3D + 24 - 2D - 24 = 2D + 60 -2D -24 will result in D = 36 these tests feel more like visualizing instead of actual math imo
brooo the way u solved it was so simple and clear, i got the same answer but u were right abt the visualizing smh like i shifted the two lower semicircles to the other top semicircles at each end, so on each end there were two whole circles + a gap of 60 under the middle semicircle, then i subtracted 24 from the gap under the middle semicircle bc of the gap of 12 on both sides and got 36 too so i guess visualization is another way to solve it, but more unnecessarily complicated lol
@@user-wh6jf1pl4e you can also find the length of the part where the second and third semicircles overlap which is 22-12=10 and it’s the same on the other side so using the third one, the diameter is 2x10+16=36. More about testing logic than anything but I’ve heard that this question was made to broaden the difficulty range so that the “gifted” students can score a little higher and they weren’t really expecting most students to be able to answer it
I found what my solution was. Look at the first semicircle and the second semicircle, they both are 22 + x = diameter but the second semicircle has the number 12 which means that the number between 12 and 16 in the diagram must be 22-12 = 10. That means one diameter is 16 + 10 +10 =36. Kinda hard to explain but I tried my best. Once u can see that the question is solved
So uh well i recently took my math psle and i was shocked to see the paper. There were literally students crying because of the difficulty of the paper even i cried after. There were so many parents concerned and now because of the new scoring system, we might not know what the ministry of education would do since there cannot be a decrease of the passing score since it depends on AL points
Yeah, I kinda feel you. I'm scared for my end exams, as I literally cannot get 4 overall in major subjects (including math) or I will get kicked out of school, and I'm already struggling with the first few tests (got 4 and 5 in math)
oml another hsr player in the wild Okay but on a serious note PSLE woth the AL system is worse, a lot of people were in tears aft my exam(myself included lmao). People were hugging, shaking each other, the class was a mess
Dang, I remember back then when I did my test math for final (it was multiple choice test btw) I just started to count my shirt button and try not to have a mental breakdown because I don't understand every single shit on my paper lol
I think it was in 3rd grade,the questions were damn hard for me lol and I had a mental breakdown,thinking my parents will prolly butcher me or smth if I score badly,and couldn't even think of dissapointing them.Bc I couldn't figure out the answers I took more time to finish the exams than everyone did and basically rushed everything,still ended up being first in class when results came out,lol.
I literally got a 1 in music(lowest grade without being ungraded) but most subjects I’m not very good at I get 6s( B I think) and at the others I get 7(A) or above, I’m practically the opposite
Now that i think about it.. the problem with school kinda is that they fucking suck at game design I mean theres so many apps that gamefy math and physics and you just cant get enough of it because its interesting once the information is well explained and the reward systems are engaging. In that sense school is just a reeeeeeally poorly designed game you have to play to unlock even harder modes equally poorly designed; and the reward for all this grind is actually being someone in life 😂 yo i feel tricked 🤨
That one question with 7 different grouping method was probably just wrong with 4 being correct. The test maker didn’t catch that mistake. I remember taking a different kind of US test, and the question was what is the correct sentence ending mark. And the correct answer was leave as it be, even though the sentence didn’t even have an ending mark. Most people chose the exclamatory mark, because period wasn’t an option…
"top classes are brutal" - I have very vivid memories of my Geography teacher being surprised that I was struggling to keep up with my Geography lessons, which were being taught in Spanish (fully English school btw). I was only 10 as well. This is not actually a joke by the way. We had the same teacher for Geography and Spanish, and she was annoyed that the school gave us less time for Spanish than for French (half an hour compared to the full hour), so she started teaching Geography in Spanish as well.
We also had the same type of thing back in the Philippines and we literally just call it the same thing as the US does. I always hated the math questions that they give because sometimes the problem is just really weirdly structured and some sentences don't really make sense because they're using a lot of adult lingo kids don't even understand.
lol, malaysian here, i remember my grandma getting me singapore test papers that were years above my grade, most of it looked like bs back then and i never really finished them, looking back it wasnt too bad but like the questions didnt make much sense alot of times
These are pretty brutal compared to what we have in Finland, but tbh as someone who really enjoyed math in school I wished we had a bit more of these harder problems on our tests... Something that really bothers me about your test is that many of these questions are badly formed and without making any assumptions they're actually unsolvable, so part of the problem becomes to figure out what assumptions the problem designers were making.
@@ruthtale95 Actually no idea. Either the horizontal little line is notation that I'm not aware of or the whole problem is just really badly made. That or the shaded area was supposed to be in colour/grayscale but got printed black so it might be covering up an important part of the diagram
The thing meant that the height of the upper (the part where it was shaded) and the height of the lower (unshaded) part is the same So yeah its just horrible printing How you are supposed to solve it is the entire triangle and then minus the unshaded part to find unshaded, but its just bad design lmao
@@ruthtale95 i think it means that the line is half of the height of the bigger triangle, if that is it the answer should be 40 but this problem is badly written
Im actually taking an exam in a few hours wish me luck boys (and girls) P.S got through the second day although Math exam is tomorrow and im not looking foward to that lol P.S.S i failed math
Some of these questions are absolutely nuts. The 5 semi-circles question that was mentioned blew my mind (even though I could figure out how to solve it).
6:50 in case people are wondering how to solve this: you know the total distance X to Y from clement (4 * 75 + 50 = 350km), and you know how far he had gotten when Daniel overtook him (2 * 75 =150km). So Daniel did the last 350 - 150 = 200km in 2 hours. So his speed was 100km/h. and he started 350 / 100 = 3.5 hours before 2pm which is 10:30 am.
Lets do a bit of fact checking. 10am-12pm-2pm = 400km (total distance to be travelled) 10am-12pm-2pm = Clement >>>350km distance covered 10am-12pm-2pm = Daniel >>> 400km distance covered (hence 50km distance ahead) If Daniel had been traveling 100km/h and started at 10:30am.... thats 3.5 hours to 2pm.... Daniel covered a distance of 350km???? Instead of 400km? (Here lies the flaw in your arguement)(Did Daniel had a head start???) Taking that the A$$hole Daniel overtook Clitoris Clement at 12pm at distance 150km..... ish... Daniel would still have to travel 150km >>> before overtaking >>>>>>>>>>>10am - 12pm 250km >>> after overtaking.>>>>>>>>>>>>12 pm- 2 pm 150km + 250 km = Still respecting the condition of 400km. Average speed of Daniel to overtake have to be the same before and after 12 pm. Danny boy is travelling at 250km/2hours= 125km/h Once the travel speed of Daniel has been establish. The time at which Daniel start is.... 150km divide by 125km/h = 1.2 hours So....A$$hole Daniel would require 1.2 hours at 125km/ h to reach 150km distance to overtake Clitoris Clement. Fair? Now that Clitoris Clement starts her journey at 10am and took 2 hours to reach 150km Now that A$$hole Daniel starts his journey at ????am and took 1.2 hours to reach 150km. A$$hole Daniel starts his journey at ???? 10:48 am..... So lets fact check again.******* 10am-12pm-2pm = 400km (total distance to be travelled) 10am-12pm-2pm = Clement >>>350km distance covered (75km/h) 10:48am-12pm-2pm = Daniel >>> 400km distance covered (hence 50km distance ahead) (125km/h) Time spent. Clement >> 4 hours >> 75km/h >> 350 km distance travelled. Daniel >> 3.2 hours >> 125km/h >> 400km distance travelled (50 km ahead) Overtaking distance at 150km condition is respected. Here is a potato Regards potato.
i just remember going into SMO (Singapore Mathematical Olympiad), and that was brutal. i'm not qualified in junior section with 2 months age difference only, so i join the senior section. oh my, what an experience.
Oh my god Singapore math Olympiad was so much harder than expected . Like of sec 1 students u learn things that you should be learning in secondary four and primary school’s SMO is wayyyyy harder than psle
No, curves work so the majority pass (C) and a smaller amount either fail or do very good. The reasoning's because if everyone got a A then the test must've been to easy. But also it can work in your advantage if heaps of people get Ds and Es then the test must've been too hard and so they change the score thresholds for each grade to be lower
I did the 2019 paper for my psle I knew everything so well I’m confident I got 97( did end up getting a*) but now I have forgotten so many things in primary school math because secondary school math is so different. Now I’m unable to solve the semi circle question without algebra but during my exam I did it in 30 seconds
The questions remind me of real IQ test questions I took with a psychologist during my stay at IMH during involuntary commitment. I was handcuffed and the psychologist gave me similar questions over 2 hours and I scored 92 on the test. I was sad that my intelligence is below normal and after that I lost faith and dropped out of poly. Right now, I don't have a future as I cannot enter uni, and am working as a clerk with only $1500 pay. Sad, but I wish I was not forced to take the IQ test but they said they needed to tell if I'm okay before they can release me, which they did after a 3 month hold where I lagged behind all my classmates.
@@melika04 92 was very bad for me :( I always wanted at least 120 ... but after I was released, every IQ test I took online to try to prove it wrong was under 100! The psychologist let me see the test results with many sub-tests. Said I'm better at verbal, but bad at spatial stuff.
3:13 They probably meant to ask how many unique combinations of 2 factors make 36 (excluding 36 x 1) so in the author's mind 4x9 == 9x4 But i agree that it should be 7
just think about it like this: we need to find a way to make groups that contain equal amounts of students. For that to be posible, since we cant make 1 group with 36 twats and we cant make 36 groups with 1 twat each, we could find our upper and lower bounds. At least we need 2 groups, so 36/2 = 18 is our higher bounds for the max amount of students in a single group. The lowest we can go has to be the smallest factor of 36, so we factor the shit out of it and we can see that 36= 2^2 * 3^2 so our smallest factor is 2, obviously we could see this without factoring but im guessing they want mathematical evidence in the exam answer to prove that the kid knows why the smallest posible group contains at least 2 individuals... anyways, now, combining all of those factors we can get groups of different amounts of twats, and we will be able to divide 36 by those values of total twats per group, cause duh, they are made out of factors of 36... so we have these groups: 1) 2 = 2 twats per group (this was our lower bounds btw) 2) 3 = 3 twats per group 3) 2*2 = 4 twats per group 4) 2*3 = 6 twats per group 5) 3*3 = 9 twats per group 6) 2*2*3 = 12 twats per group 7) 2*3*3 = 18 twats per group ( this was our upper bounds btw) And we can divide 36 by all of these numbers. So. We can make in total 7 different kind of arrangements to form groups full of twats that make up 36 individual cunts in total. Now, the question is, why the fuck does the paper say its just 4? Most probably, the person who made that question was a twat and saw 4 factors make up 36 (2*2*3*3) and thought "yeah this seems legit, the answer must be 4!" and that's how the wrong fucking answer made it into the final paper.
@@MultiSuperGuide Something similar happened here this year in our university access exam, there was a question that was imposible to solve because they didnt give enough information (apparently they copy pasted the question from another exam and forgot to paste the last line, where the missing part of the info was... not only that but the question was from the social studies and economics branch rather than the science branch, so it we werent allowed to use any of the stuff we learned in the science branch to solve it...) and everyone complained, they even took some signatures and shit, and in the end the complaint went nowhere... they ignored it and everyone lost 2 points... (My country is organized in different regional territories, and the exam is made on a region by region basis, so each region has a different exam, basically, the whole region i live in lost 2 points in that exam just because the state was too lazy to admit their fuck up lmao)
@@AlFredo-sx2yy Very late to this post. But when I read the question I believe it said that there had to be an even number of "twats" in the final group. And you couldn't have 36. So you can get 7 different combinations of easily divided twats, but you could only get 4 groups that had an EVEN number of twats in them. Please feel free to correct me if I am wrong. I am having a small aneurysm trying to figure out the pets in the pet store problem.
i remember taking something similar to PSLE (indonesian version). Well, everyone went for extra lessons bla bla bla and me sitting at home with 7 stacks of 700-paged books filled with practice questions. Guess what... i got 272 (considered an excellent score, remembering that the max score you get is 300)
Some subjects are, but other subjects you can memorise, but you don’t need to memorise everything as you can figure out some of the stuff using logic and/or common sense
For question 5 at 3:08 I don't get how it's 4 ways. It can be divided into 2, 3, 4, 6, 9, 12 and 18 groups so there are 7 ways to divide it, not 4. I'm quite sure that the answer key is wrong because it makes no sense otherwise.
@Tudi20 Creating 18 groups of 2 isn't the same as creating 2 groups of 18, I highly doubt that the people making standardized tests for an entire country would be that braindead. I'm sure it's a mistake.
the hard part is turning the info given into equations. then its just solving systems of equations which is pretty easy basic math. But i definitely couldn’t do that in 6th grade. that grouping question was bs though, its definitely 7 groups. On a tangent, Ive noticed (in the US) math in middle school and primary school are more word problems and applied mathematics ig. when you’re younger they probably want to hone your problem solving and logical thinking. When you’re older its more rules and stuff you have to memorize, and science classes(physics, chemistry) have more applied math. on another tangent, iv’e seen some of my friend’s comp sci homework at their university and that shit looks ridiculously hard. Im not a computer guy so I was surprised at how much math coding was.
My 4th grade grades starts to decline fast. A-D. However, the lucky thing is, MAJORITY OF CLASSMATES OF MINE TOO! Only the top students have high marks......Also, it was a chinese school. So yeah, it's more challeging than ever. My mom is working in a high school, and I was shocked by the grades. Almost all of the students gets 50 to 20 marks-
The thing with school is when to finally graduate, the only useful things that carries over is real-life situation that you will need if you’re going to college. If you aren’t, then you forget nearly 90% of things they teach you in school..
If you go into a trade after you finish school, you don't need most of the things you learned. lol Or if you get a basic job and you're fine with it. If you want a higher level job it does become important but not everyone wants a high level job Many people are satisfied being welders, truck drivers, etc.
I figured out some of the questions, and here's how I thought about them. On number 4, you're supposed to figure out how many divisors of 36 there are, and they tell you you can't have groups of 1 and 36. The prime factorization of 36 = (3^2)(2^2), which means there are 9 divisors because there are 3 outcomes for (3^n) and (2^m) where n and m are between 0 and 2, both ends inclusive. Thus, there 3x3 = 9 outcomes minus the 2 outcomes they don't want, i.e., groups of 1 and 36. Finally, we have 7 groups. Number 12. She spotted the 90 degree angle like I did, and it's a big hint. You don't have to know how many cats, dogs, whatever because you know the percentages each group represents. Because there's a 90 degree angle, the fish group is 1/4 of the total or 25%. That means the percentage of cats there are 100 - 22 - 8- 10-25 = 35%. (Subtracting the percentages we know out of the whole.) Let T be the total, then there are .1T hamsters and .35T cats, and we know there are 20 more cats than hamsters. That means .1T = .35T-20. Do some simple algebraic manipulation and simplification, and you get T = 80. At time 3:46, you're supposed to realize that they both share the same line, which means that d+12+d+12+d has the same length as 22+d+16+d+22 where d is the diameter of the semicircle. That means you need to isolate d in this equation 3d+24 = 2d +60 (I just added alike terms from before) because we know the lengths are the same. Thus, d = 36. This is what I was able to figure out from the questions she did show, and I wanted to actually solve. For the most part, this is just puzzle solving. It tests your ability to reason with the hints that are given.
I am procrastinating on my actual math homework while spending time doing the question on the PSLE paper in the video lmfao, I don’t know why UA-cam can motivate me to do things that I normally don’t do
Here in Brazil we have ENEM, it's a test that (almost) everyone that is in the last year of highschool needs to do. Basically you do this test to get into a good University. I've seen kids in 8th grade already studying for the test, and the parents really want their kids to go to the Federal University here.
god i still remember taking the maths PSLE paper and about 2 days later everyone and their mother was talking about the infamous $1 coin question that i'm still confused as to the reason why it was put in there to this day
On Q37 my teacher showed me a table call BHA basically in the B section put down the first ratio'd numbers and in H put down a + or - the given number and on A you get the after ratio. Then you have to do some multiplication stuff, during remedial my cher taught us to use it in calculator where you can go onto equation mode,simul equation,2,on x type the before number and on y type the after number from there it will be easier
i was performing very very badly in maths during my primary school years. I was fortunate to have supportive teachers helping me out and giving me remedial everyday of the week. I kinda passed psle with 196 t score and now i take additional maths with no problems whatsoever
I saw the thumbnail and flashbacks to seeing that question in the paper in the school hall and honestly it was not that hard but it was still interesting to see such a question in a psle when all the other papers were really much easier. (Honestly the triangles question was a lot easier than the diameter one lol) Not surprising tho, psle likes to make two out of four papers hard.
@@gatobeans honestly, just listen in class and take notes and be calm. PSLE seems a lot bigger than it actually is but honestly it is not that bad, just don’t stress during the paper too much.
@@you_key yeah but some thing like composition the teacher can't really teach and that's what I'm weak in so....yeah....since I'm in top class Cher's expectations are at least a 30/40 but I usually get just by with 27-28 maximum
@@gatobeans that one takes practice and a lot of reading, maybe try picking up some handbooks that have idioms and good vocabulary, I mean the least you can know is similes as they are quite simple. If you know the show not tell method, do use it haha
3:05 First, let's write all the factors of 36 1,2,3,4,6,9,12,18,36 that's 9 factors You are told that there is more than 1 group and fewer than 36, which means you can cross off 1 and 36 that leaves you with 7 Now let's pair up which factors you multiple by which to get 36 12*3 = 36 4*9 = 36 6*6 = 36 18*2 = 36 that's 4 pairs so basically you could have 7 if you make 1 of the numbers the students and the other the classes, and then switch them over, but for some reason, if the answer they want is 4, they don't count switched values, they just want the number combinations.
Oh gosh this reminds me of the time I was struggling in college lol. Miss G gonna be so furious. Thinking back about it tho, it might not be that bad after all, the PSLE questions, I think it boils down to student's capabilities rather than the subject itself, like a lot of people said this is unnecessary information and I agree, to certain degree you don't need high mathematical skills until you're like working as a businessman or researcher and so on, basic math is enough to go thru daily lives. At such a young age, what we need is actually stimulation to spark our logical and imaginative thinking, like in preschool it's enough with just looking at pictures and looking around you, entice a child curiosity to know stuff, know names and the like but as we got older such stimulus is no longer enough and we need something more intricate and more rigid. Which is why I believe these kind of mathematical question gives situation alongside them to let the student imagine a certain problem and using a certain set of rigid rule which is math to find the logical solution. For me I think it doesn't have to be math tho, literally any rule works, even in gaming there's certain rule to how we play the game to keep it fair and challenging, like if you play pokemon, you know it's a turn based battle, so your brain is thinking of all kind of stuff like, how many HP I have left, should I attack? Should I use potion? should I switch pokemon?, all these are good stimuli for your brain. I will say kids who play games and do well in it are just as smart as kids who studies a lot and do well in it, based on brain capability. What sets them apart during exam and classes is the "rule" they use. if those gamer kids don't know the "rule" to play the game(math), how can you expect them to do well? they are basically on an away game in that exam hall, if only they knew what they need to know which is the rule, they'll do soo much better. of course I'm not saying better than the kids that actually studies, but that depend on the kids themselves. On that note I'll also touch on repetition, like back in school, a lot of people told me math isn't a subject that you study to 'understand', instead you study math by doing a lot of exercises till you got it. Yeah I agree, after all if we go by my analogy just now studying math to 'understand' it is like reading the game manual without actually playing it, you won't get good that way, but hey in hindsight, if I don't know the rule before doing it, don't you think I'll mess up big time? so please, don't stop people of they're trying to 'understand" math, instead guide them through it by doing a few question with them and allowing them to try their hand on some math. This is like you finding a veteran player to carry you in moba lol, studying really is just like gaming.Which reminds me.. I never touched on repetition like I said I would lol, got distracted, so anyway, what I was trying to say with the repetition thing, just like in moba where you skill improves and get more polished the more you play, the same thing goes for your study as well, so now it's not a matter if you're smart or not, it's a matter of whether you want or not. Btw I never cited any source or anything in this little writing I made, so to prove my point, just look at Katsuragi Keima from TWGOK and Sora and Shiro from No game, No Live, they are all top gamer and excellent study as well. That's all I have for this academic outlook for now, see you later lol.
3:13 Shouldn't this be 7 since the question wasn't "how many ways can you multiply 2 numbers to get 36", it was how many equal groups of people we can make? If even the answer key is getting it wrong, no wonder people are. 3:32 Let's use logical reasoning here. We'll assume that since we're talking about live animals, all of these values must be integers. We know that: H == 10% B == 22% D == 8% F on the chart has a right angle (as represented by the square) ==> F == 25% Because of this: C == 100%-(10%+22%+8%+25%) == 35% We also know that H + 20 == C Let's take X to be H: H == X, then: C == X + 20 Since we know that C is 35%, and F == 25%: F == 35% - 10% F == C - H F == (X + 20) - (X) F == 20 Therefore: n% == (n/25)*(25%) == n/25*20 C == 35/25*20 == 28 H == 8 D == 8/25*20 == 6.4 B == 22/25*20 == 17.6 H+B+D+F+C = 80 Therefore, while in a purely number-based context, 80 may be a correct answer for the distribution of these numbers, realistically speaking, you cannot divide up 80 animals into these percentages, as they would end up as fractions. 3:46 This is just a simple linear equation You have the top side, which is equal to the diameter of 3 circles, plus the 2 times 12 spaces Then you have the bottom side, which is equal to the diameter of 2 circles, plus the 2 times 22 spaces, and the 16 space 22+22+16+2D == 12+12+3D 60+2D = 24+3D 36+2D = 3D 36 = D Answer: The diameter of a circle is 36. 5:57 If Tessa saved 4, then Judy saves 5. If Judy saves 3, then Polly saves 2. We'll take Tessa as the base of our calculations. If we assume that Tessa has saved 4 dollars, then all the rest of them will have saved the following: Tessa: 4 Judy: 5 Polly: (Judy / 3) * 2 == 10/3 With the above information, we can create an equation for their total savings. Here, we'll represent the amount of money they have to save to get to the goal as X, again. 4X + 5X + 10X/3 = 1850 9X + 10X/3 = 1850 27X + 10X = 5550 37X = 5550 X = 150 Therefore, Tessa must save 150 for the three of them to get 1850$. Now convert this value to Polly's savings 10X/3 == 10*150/3 == 500 Answer: Polly has saved 500 dollars. 6:34 C started at: 10:00 D started at: ? At 2 pm, C was 50km away from the city. ==> (10:00-14:00)*75 == 300km travelled. Total distance between cities: 300 + 50 == 350km D passed C at 12:00 ==> C travelled 2*75 == 150km at this point. ==> Meeting point A == 150km After passing C, it took 2 hours for D to reach the city. ==> (Total distance to city) - (Meeting point A) == Distance travelled in two hours == 200 Divide D's 2 hour travel distance by 2 to get his average travel speed of 100km/h Answer: Daniel's average speed is 100km/h D started at: ? The total time necessary for D to get from city X to city Y is the total distance divided by his speed. ==> 350/100 == 3.5 hours. We know he arrived at 2 pm, so he started at 14 hours - 3.5 hours == 10.5 hours == 10:30 am Answer: Daniel started at 10:30 am.
Math is my field of study (I'm in AI specifically) so I love this kinda stuff, but I know for a fact we never got anything close to this in primary school. Some of these are pretty tricky, and you need a lot more knowledge than just arithmic, this is actual math
Alright, I went back and answered two questions that Jolene didn't know how to answer: 12. (pie chart with hamsters) and 36. (saving money). Here is the correct answers with working. I am also in my first year of university, and I found these challenging, so don't get too annoyed if you didn't get them, it is really brutal for 12 year olds. *_12. The pie chart below shows the different types of animals in a pet shop. If there are 20 more cats than hamsters, how many animals are there in the pet shop?_* *This question uses ratios and simultaneous equations* To start with, the graph is highly deceiving. I started calculating first thinking that Hamsters + Cats = 50% of total, but it doesn't add up right. The fish is quarter of the graph, so 25% Adding up all the remaining percentages gives us 65% 100 - 65 = 35% Cats, which means that 35% of the total pet shop is made of cats. Therefore, the ratio of cats to hamsters is 35 to 10, or 7 to 2 (for every two cats, there are seven hamsters). To simplify this, let's make hamsters *H*, and cats *C*) If 2 cats = 7 hamsters, then 2C=7H. We also know that there are 20 more cats than hamsters, so C - H = 20 We want to have only one variable, and in this case the easiest will be changing the cats. If 2C = 7H, then C = (7H)/2 Putting that back in to the original equation gives us ((7H)/2) - (2/2)H = 20 This makes (5/2)H = 20, which can be written as (5H)/2 = 20 multiplying by 2 then dividing by five gives us H = 8, which means that there are 8 hamsters in the pet shop. If 8 hamsters is 10%, then 100% of the animals is Hamsters * 10 = 80 The correct answer to this question is 2) 80. *_36. For every $4 Tessa saves, Judy saves $5 and for every $3 Judy saves, Polly saves $2. How much does Polly save if the three of them save $1850 together?_* *This question uses ratios* To start with, there are two different rates Judy saves. We should make them the same amount. We can do this by multiplying Tessa:Judy by 3 and Judy:Polly by 5. This gives us the equations of $12 Tessa to $15 Judy, and $15 Judy to $10 Polly. We can then make them equal to each other, with the equation becoming 12 Tessa to 15 Judy to 10 Polly (12J = 15J = 10P). This can now be written as a ratio of Tessa:Judy:Polly (12:15:10). The total of this is 37. In total, they have saves $1850 together. To see how much one part is, we divide by 37, which gives us a nice even $50. Now that we know one part is $50, Polly's ten parts means that the amount she has saved is ($50 * 10) which equals $500. The correct answer to this question is $500
Can u tell me how to solve question 16? ( the one at 4:32 ) I am confused about what the straight line means, cuz if it means to divide the height into 2 equal parts then why is it located below the vertex instead of being on it
Correction: Question 13 does not require Ratios or Simultaneous Equations. First off, you calculate the percentage of Cats in the Pie Chart. It'll be: 100%-(22%+8%+25%+10%) =35% Second, because it is stated in the question that there are 20 more cats than hamsters, we find the difference in percentage of hamsters and cats. That'll be: 35%-10%=25% As aforementioned, the are 20 more cats than hamsters, so this means that: 25%=20 and 100%=80, hence the answer out of the 4 choices is 2
but 22% of 80 is 17.6 birds and 8% of 80 is 6.4 it took me 30 minutes to realize that the number of pets is imprecise i know 80 is the correct answer though
@@Anna-kz7km Im pretty damn sure they didnt give enough information to even solve the question. I tried it for like 20 minutes and it just doesnt seem to add up. This is pretty likely since 2 questions in the test (the teacher question and the pie chart question) were poorly made. I wouldnt worry too much about it this whole test is garbage
For the semi circle equation you can find the equal overlapping parts and set up the following equations (leftmost top semicircle) 22 + x = diameter, with x being the length of the overlap with the leftmost bottom semicircle (center top semicircle) 16 +2y = diameter, with y being the length of the overlap with the leftmost bottom semicircle (leftmost bottom circle) 12 + x + y = diameter, with with x being the length of the overlap with the *leftmost top semicircle* and y being the length of the overlap of *center top semicircle* Because 22 + x = diameter and 12 + x + y = diameter 22 + x = 12 + x + y Subtract x from both sides 22 + x = 12 + x + y - x = - x ___________________ 22 = 12 + y subtract 12 from both sides and you get 10 = y Since 16 + 2y = diameter substitute y in 16 + 2(10) = diameter diameter = 36 I wish I could draw a diagram, which would make it a lot easier, but I hope it helped.
3:15 If you find the factors of 36, you will find 5 (n * n) ways to get 36. Since one of them is 1 * 36, which in the question stated should not be included, there are 4 ways.
factors of 36 is not correct for the question. Because multiplication factors assume 2x18 and 18x2 is the same. But 2 groups of 18 people and 18 groups of 2 people are VERY different
O right... Im stupid haha... Then the answer key is probably wrong, maybe the ppl who wrote the paper also didn't account for this Thanks for telling me
the reason there are so many trick questions is because they need a curve. its not made to get people to a certain math level, its to see who is the "best"
Regarding the "boys in groups" question, couldn't you have either (1) 18 groups of 2 boys, (2) 12 groups of 3 boys, (3) 9 groups of 4 boys, (4) 6 groups of 6 boys, (5) 4 groups of 9 boys, (6) 3 groups of 12 boys or (7) 2 groups of 18 boys? I agree with your 7 ways and if they say there are only 4 ways, then I'm really curious about their reasoning...
@@qwerty19811 it is the same. They say equal number of students. If the question stated EVEN number of students only then 12 groups of 3 boys can't be it

I do agree with your sentiment here. I'm decent at math, but at the same time, I don't feel like this is useful when it comes to adulthood UNLESS! If a kid really likes solving math and/or want to be a teacher (of math) or an accountant (or any careers involving deep understanding in math), so since I wanna be a business owner or a business manager, I think this kinds of problems and equations are not really mandatory and necessary for a kid to learn if the kid is not interested in it in the first place. But I do think that basic math is for everybody and that is the one that is very mandatory and it makes sense why people need to know basic math for future adulthood and stuff. I don't see the purpose of learning how to solve deep equations and problems that can actually benefit me in life. This is just my opinion tho.
I respectfully agree, but I hope in the future teacher of math or accountant would not exist at all because AI might be able to do anything related to math. Since ai is good at math and humans are good at using creativity to solve real life problems, the world can become better for everyone.

Clement is still 50 km away from Town Y (2 pm - 12 pm) = *2 Hours* So, Distance between "Daniel Passes Clement" to "Daniel reach town Y and Clement is still 50 km away" is *150 km* --> (75 x 2 = 150) Distance between "Daniel Passes Clement" to Reach town Y for Clement is = 150 + 50 = *200 km* 200 km and Daniel did it in 2 hours --> Average Speed of daniel = 200/2 = *100 km/h* b.

the reason the math test for a 12 year old would be a nightmare, is because it's purposefully useless information, you're supposed to overwrite that info by now, so it's fine.
I definitely think that children that young shouldn't be put through exams like this one and I am really not a fan of the way maths is taught in most places around the world. Maths truly is about problem solving and using logic. It's not useless information, maths is used literally everywhere from business to computer science or physics. Even if you don't go to work in a STEM field you're still going to need it in one way or another especially now. Being a better thinker allows you to make better decisions when you encounter new evidence or statistics and for that you need maths.
And on top of that what concepts that we're being 'taught' is nothing compared to what the world of mathematics is And in my experience I would say the subject is pretty ripe with hypothesis such as 3x+1 (check out Veritasium's video) not being solved and many more
@@sergiuszstrzelczyk7984 finally. I feel like the way schools teach math does not represent math at all in its entirety. Its just rote learning and makes people dislike math even more. In university, math is taught in a way that you require understanding so that you are able to write proofs.
Edit: forgot to mention, when complex variables was first discovered, it was not used for any applications at all. But as time passed, someone found it was quite useful (for something.. you can google it i forgot what it was lol) and thus it is used in many areas of STEM today such as physics and engineering.
@@sergiuszstrzelczyk7984 as someone who's taking compsci, i don't think i ever had to use math past 3rd grade level, considering the computer does the equation and you just have to use basic mathematical thinking; something an adult can learn within a day or two from scratch
I mean learning how to think logically takes time and the same goes for problem solving. For some people it may be easier but still it takes time to develop an understanding of certain concepts and an ability to think mathematically. If everyone could do this in a day we wouldn't have textbooks or any formal system of education. Not everyone needs complicated maths in their life but it's good to know at least some maths. Btw I'm not sure if you're talking about university or something but mathematics is an intrinsic part of computer science. Discrete mathematics so areas like logic, set theory, combinatorics, graph theory and number theory as well as different areas of maths are important for designing efficient algorithms, analyzing computational complexity etc.

I remember hearing about this test from a Singaporean and being appalled that they would pretty much use this test to ban kids from being a doctor or whatever they wanted so young
I don’t think that’s how it works, but if you f up on this test then it’s somewhat going to affect the future career(Secondary School then College or Polytechnic and the University)
Yeah it's kinda f'ed up. I think a lot of Singaporeans actually don't realise how much your PSLE score can affect your education and career. If you don't do well for PSLE, your secondary school might not even offer pure sciences as a subject you can take, so if you wanted to become a doctor you likely will never make it.
I like videos like this because they’re just therapy to show other people in a similar situation
I'm in college right now actively taking a calculus based physics class and I fully admit I probably would've failed that test. You rarely ever use primary school math outside of its fundamental building blocks to learn other maths. Like I can't do fractions, I have to convert to decimal then back if the answer needs to be a fraction.
well i would think having a concrete number would be better unless it irrational fraction/decimal
Learn fractions. I don't know how you can do calculus without understanding them. What do you struggle with (adding them, multiplying them, I'm just confused)?
@@caenir you don't need to know fractions if you're fine using decimals. There may be extra steps involved but everything depends on how much effort you want to put into the problem.
@@OneFinalAutumn Cool. But fractions are basic as hell. Also try representing 2/3 as decimals, you'll only ever get an approximation
@@caenir well 2/3 is also an approximation, but yeah, I agree they're simple to understand. But they really aren't necessary. Most of the time things can be purely understood and rationalized with a decimal. It's just a matter of preference.

@@uttkarshtewari2532 I mean, we started learning algebra at age 12 so it's reasonable, and i think most schools teach problem solving in math class since 4th or 5th grade.

@@streamgirlsnight idk might be my country
As a big boi well over 12, and as someone who's somewhat decent at math, that pie chart question was doable for me, but I can't imagine a 12 year old having to think of a solution to that while giving an exam, there's some pretty tough algebra there.
And I'm not even going to even begin doing the semicircle question, I don't have the time xD
But yeah maybe you're right, maybe it's much easier as a 12 year old cause that's when you're studying this kind of stuff
@@streamgirlsnight different countries have different standards
For the speed distance question, there are some hints to the question. The way they requested you to find Daniel's speed in part a and then the time he started his journey suggested that you shouldn't use Total Distance/total time.
a) @12pm, D overtook C. D complete his journey at 2pm while C is 50km away. That suggested that from 12pm to 2pm, C travelled 75x2 = 150km. Since C is 50km away from town Y, that means D travelled 200km from 12 to 2pm.
Hence, the average speed of D is 200/2 = 100km/hr.
b) Total distance from town x to y = (75x4) + 50 = 350km
Since D's average speed is 100km/hr (found in part a), his time taken to complete the entire journey = 350/100 = 3.5 hours
Since D complete the journey at 2pm, he starts his journey @ 1030am.
*check: if D starts his journey at 1030am, at 12pm, he would have travelled 150km, which is the same amount of distance travelled by C. For such questions, when they say overtake, it literally means they met one another. I always feel that they should phrase this kind of questions better.

I got flashbacks from the time i entered LGS when I saw those questions, which stands for "Highschool Entrance Exam" (in turkish). I was in 8th grade.
The math questions were horribly hard. They had multiple subjects you needed to use for one question, obtuse illustrations, way too hard and lenghty explanations of the images+the questions and some questions had stuff we didn't learn throughout 8th grade, which had most of the material used for the exam questions. They were asking these questions to 13-14 year-olds. I remember almost crying out of stress. Plus 3 wrong questions elliminates one correct answer.
So i got 8 questions right, 8 questions wrong and left 4 questions blank. Because of this 3 wrongs-1 elimination method, the system calculated that I got 5.33 questions right. Which is kind of a slap to my face.
Anyway. I got 393/500 points and got into top 14% in Turkey. Guess what? Couldn't even get into a good highshool because the most mediocre ones start from top 13%. I had to settle in with an occupational highschool that teaches a lot of redundant lessons, takes up my time 9 hours a day, and teaches me sciences even though i will never use them during the university exams.
(You take 2 different kinds of exams in here. Each one has 3 different categories.
TYT and AYT.
TYT stands for "Basic Competency Test", which has 9-10th grade subjects (including stuff from middle school).
AYT stands for "Field Competency Test". In this one, you solve the stuff you learnt in 11th-12th grade.
For AYT, you use the things you learnt from the point you chose a field in highschool.
1) One category for maths, turkish literature, biology, physics, chemisty.
2) One category for maths, turkish literature, philosophy-1, geography-1, history-1. (Which is the category i need to solve tp get to the university i need to go in)
3) One category for turkish literature, history-2, geography-2, philosophy-2, maths. (There is a difference between 1 and 2)
Instead, i had to choose between being a nurse helper, a midwife helper and a healthcare technician. The system put me in the nurse helper category.

A Turkish person here, we also have a similar exam system for 8th graders (12-13-14) called LGS to get a good high school. The exam has on 6 lessons (Math, Science, English, History/Social Studies, Turkish & Religion) and a scoring on 500. (if you get over 400, you're going to a good school! ) However, the questions are as hard as the questions shown here! Some are even harder, especially for math. There are some questions which take up a whole page! I'm currently studying for this exam, and it's very very hard..
The system has changed, there's now AL's.
The minimum score is 4, basically O Levels
Edit: there, i edited it, stop @ing me please
I dont rly like the new scoring system AL 6 is a terrible score the range is so high

wha why everyone here so smart one
3:46 isn't this just basic equality but with weird representations, the graph just makes it look weird
say that D stands for a diameter
we have 2 segments that are equal in lengths so we can set them equal to each other, the first one consists of 3 Semi circles and 2 gaps with lengths of 12, the other is 2 semi circles with 3 spaces with lengths of 22, 16, 22.
3D + 24 = 2D + 60
subtract (2D + 24) to the whole thing
3D + 24 - 2D - 24 = 2D + 60 -2D -24
will result in
D = 36
these tests feel more like visualizing instead of actual math imo
brooo the way u solved it was so simple and clear, i got the same answer but u were right abt the visualizing smh
like i shifted the two lower semicircles to the other top semicircles at each end, so on each end there were two whole circles + a gap of 60 under the middle semicircle, then i subtracted 24 from the gap under the middle semicircle bc of the gap of 12 on both sides and got 36 too
so i guess visualization is another way to solve it, but more unnecessarily complicated lol
@@user-wh6jf1pl4e you can also find the length of the part where the second and third semicircles overlap which is 22-12=10 and it’s the same on the other side so using the third one, the diameter is 2x10+16=36. More about testing logic than anything but I’ve heard that this question was made to broaden the difficulty range so that the “gifted” students can score a little higher and they weren’t really expecting most students to be able to answer it
I did this paper for my psle I still don’t know how I solved this in 30 seconds I can’t do it now without the help of algebra
I found what my solution was. Look at the first semicircle and the second semicircle, they both are 22 + x = diameter but the second semicircle has the number 12 which means that the number between 12 and 16 in the diagram must be 22-12 = 10. That means one diameter is 16 + 10 +10 =36. Kinda hard to explain but I tried my best. Once u can see that the question is solved

We had the same teacher for Geography and Spanish, and she was annoyed that the school gave us less time for Spanish than for French (half an hour compared to the full hour), so she started teaching Geography in Spanish as well.

Some of these questions are absolutely nuts. The 5 semi-circles question that was mentioned blew my mind (even though I could figure out how to solve it).
6:50 in case people are wondering how to solve this: you know the total distance X to Y from clement (4 * 75 + 50 = 350km), and you know how far he had gotten when Daniel overtook him (2 * 75 =150km). So Daniel did the last 350 - 150 = 200km in 2 hours. So his speed was 100km/h. and he started 350 / 100 = 3.5 hours before 2pm which is 10:30 am.
smart i don't even know how-
Lets do a bit of fact checking.
10am-12pm-2pm = 400km (total distance to be travelled)
10am-12pm-2pm = Clement >>>350km distance covered
10am-12pm-2pm = Daniel >>> 400km distance covered (hence 50km distance ahead)
If Daniel had been traveling 100km/h and started at 10:30am.... thats 3.5 hours to 2pm.... Daniel covered a distance of 350km???? Instead of 400km? (Here lies the flaw in your arguement)(Did Daniel had a head start???)
Taking that the A$$hole Daniel overtook Clitoris Clement at 12pm at distance 150km..... ish... Daniel would still have to travel
150km >>> before overtaking >>>>>>>>>>>10am - 12pm
250km >>> after overtaking.>>>>>>>>>>>>12 pm- 2 pm
150km + 250 km = Still respecting the condition of 400km.
Average speed of Daniel to overtake have to be the same before and after 12 pm.
Danny boy is travelling at 250km/2hours= 125km/h
Once the travel speed of Daniel has been establish.
The time at which Daniel start is....
150km divide by 125km/h = 1.2 hours
So....A$$hole Daniel would require 1.2 hours at 125km/ h to reach 150km distance to overtake Clitoris Clement.
Fair?
Now that Clitoris Clement starts her journey at 10am and took 2 hours to reach 150km
Now that A$$hole Daniel starts his journey at ????am and took 1.2 hours to reach 150km.
A$$hole Daniel starts his journey at ???? 10:48 am.....
So lets fact check again.*******
10am-12pm-2pm = 400km (total distance to be travelled)
10am-12pm-2pm = Clement >>>350km distance covered (75km/h)
10:48am-12pm-2pm = Daniel >>> 400km distance covered (hence 50km distance ahead) (125km/h)
Time spent.
Clement >> 4 hours >> 75km/h >> 350 km distance travelled.
Daniel >> 3.2 hours >> 125km/h >> 400km distance travelled (50 km ahead)
Overtaking distance at 150km condition is respected.

Whenever I hear that a test gives results based on a curve, that makes me think that whoever's making these tests don't want the majority to succeed.
Ergo, the majority doesn't succeed.
No, curves work so the majority pass (C) and a smaller amount either fail or do very good. The reasoning's because if everyone got a A then the test must've been to easy. But also it can work in your advantage if heaps of people get Ds and Es then the test must've been too hard and so they change the score thresholds for each grade to be lower

3:13 They probably meant to ask how many unique combinations of 2 factors make 36 (excluding 36 x 1) so in the author's mind 4x9 == 9x4
But i agree that it should be 7
just think about it like this: we need to find a way to make groups that contain equal amounts of students. For that to be posible, since we cant make 1 group with 36 twats and we cant make 36 groups with 1 twat each, we could find our upper and lower bounds. At least we need 2 groups, so 36/2 = 18 is our higher bounds for the max amount of students in a single group. The lowest we can go has to be the smallest factor of 36, so we factor the shit out of it and we can see that 36= 2^2 * 3^2 so our smallest factor is 2, obviously we could see this without factoring but im guessing they want mathematical evidence in the exam answer to prove that the kid knows why the smallest posible group contains at least 2 individuals... anyways, now, combining all of those factors we can get groups of different amounts of twats, and we will be able to divide 36 by those values of total twats per group, cause duh, they are made out of factors of 36...
so we have these groups:
1) 2 = 2 twats per group (this was our lower bounds btw)
2) 3 = 3 twats per group
3) 2*2 = 4 twats per group
4) 2*3 = 6 twats per group
5) 3*3 = 9 twats per group
6) 2*2*3 = 12 twats per group
7) 2*3*3 = 18 twats per group ( this was our upper bounds btw)
And we can divide 36 by all of these numbers. So. We can make in total 7 different kind of arrangements to form groups full of twats that make up 36 individual cunts in total.
Now, the question is, why the fuck does the paper say its just 4? Most probably, the person who made that question was a twat and saw 4 factors make up 36 (2*2*3*3) and thought "yeah this seems legit, the answer must be 4!" and that's how the wrong fucking answer made it into the final paper.

For question 5 at 3:08 I don't get how it's 4 ways. It can be divided into 2, 3, 4, 6, 9, 12 and 18 groups so there are 7 ways to divide it, not 4. I'm quite sure that the answer key is wrong because it makes no sense otherwise.
Ikr I was weirded out on that one as well
Yeah I got 7 as well
@Tudi20 Creating 18 groups of 2 isn't the same as creating 2 groups of 18, I highly doubt that the people making standardized tests for an entire country would be that braindead. I'm sure it's a mistake.
Math is disgusting
Could be that the answer sheet is wrong, not like that never happens
the hard part is turning the info given into equations. then its just solving systems of equations which is pretty easy basic math. But i definitely couldn’t do that in 6th grade. that grouping question was bs though, its definitely 7 groups.
On a tangent, Ive noticed (in the US) math in middle school and primary school are more word problems and applied mathematics ig. when you’re younger they probably want to hone your problem solving and logical thinking. When you’re older its more rules and stuff you have to memorize, and science classes(physics, chemistry) have more applied math. on another tangent, iv’e seen some of my friend’s comp sci homework at their university and that shit looks ridiculously hard. Im not a computer guy so I was surprised at how much math coding was.

My 4th grade grades starts to decline fast. A-D. However, the lucky thing is, MAJORITY OF CLASSMATES OF MINE TOO! Only the top students have high marks......Also, it was a chinese school. So yeah, it's more challeging than ever. My mom is working in a high school, and I was shocked by the grades. Almost all of the students gets 50 to 20 marks-
The thing with school is when to finally graduate, the only useful things that carries over is real-life situation that you will need if you’re going to college. If you aren’t, then you forget nearly 90% of things they teach you in school..
If you go into a trade after you finish school, you don't need most of the things you learned. lol Or if you get a basic job and you're fine with it. If you want a higher level job it does become important but not everyone wants a high level job Many people are satisfied being welders, truck drivers, etc.
I figured out some of the questions, and here's how I thought about them.
On number 4, you're supposed to figure out how many divisors of 36 there are, and they tell you you can't have groups of 1 and 36. The prime factorization of 36 = (3^2)(2^2), which means there are 9 divisors because there are 3 outcomes for (3^n) and (2^m) where n and m are between 0 and 2, both ends inclusive. Thus, there 3x3 = 9 outcomes minus the 2 outcomes they don't want, i.e., groups of 1 and 36. Finally, we have 7 groups.
Number 12. She spotted the 90 degree angle like I did, and it's a big hint. You don't have to know how many cats, dogs, whatever because you know the percentages each group represents. Because there's a 90 degree angle, the fish group is 1/4 of the total or 25%. That means the percentage of cats there are 100 - 22 - 8- 10-25 = 35%. (Subtracting the percentages we know out of the whole.)
Let T be the total, then there are .1T hamsters and .35T cats, and we know there are 20 more cats than hamsters. That means .1T = .35T-20. Do some simple algebraic manipulation and simplification, and you get T = 80.
At time 3:46, you're supposed to realize that they both share the same line, which means that d+12+d+12+d has the same length as 22+d+16+d+22 where d is the diameter of the semicircle. That means you need to isolate d in this equation 3d+24 = 2d +60 (I just added alike terms from before) because we know the lengths are the same. Thus, d = 36.
This is what I was able to figure out from the questions she did show, and I wanted to actually solve. For the most part, this is just puzzle solving. It tests your ability to reason with the hints that are given.
I love how you’re doing this out of the random.
*and I have no motivation to do everything.*

Here in Brazil we have ENEM, it's a test that (almost) everyone that is in the last year of highschool needs to do. Basically you do this test to get into a good University. I've seen kids in 8th grade already studying for the test, and the parents really want their kids to go to the Federal University here.
We have the same in Singapore, called the O Levels or the Cambridge Ordinary Level.

god i still remember taking the maths PSLE paper and about 2 days later everyone and their mother was talking about the infamous $1 coin question that i'm still confused as to the reason why it was put in there to this day
On Q37 my teacher showed me a table call BHA basically in the B section put down the first ratio'd numbers and in H put down a + or - the given number and on A you get the after ratio. Then you have to do some multiplication stuff, during remedial my cher taught us to use it in calculator where you can go onto equation mode,simul equation,2,on x type the before number and on y type the after number from there it will be easier
i was performing very very badly in maths during my primary school years. I was fortunate to have supportive teachers helping me out and giving me remedial everyday of the week. I kinda passed psle with 196 t score and now i take additional maths with no problems whatsoever

I saw the thumbnail and flashbacks to seeing that question in the paper in the school hall and honestly it was not that hard but it was still interesting to see such a question in a psle when all the other papers were really much easier.

3:05 First, let's write all the factors of 36
1,2,3,4,6,9,12,18,36
that's 9 factors
You are told that there is more than 1 group and fewer than 36, which means you can cross off 1 and 36
that leaves you with 7
Now let's pair up which factors you multiple by which to get 36
12*3 = 36
4*9 = 36
6*6 = 36
18*2 = 36
that's 4 pairs
so basically you could have 7 if you make 1 of the numbers the students and the other the classes, and then switch them over, but for some reason, if the answer they want is 4, they don't count switched values, they just want the number combinations.
I feel really smart now lmao. Though tbf, math is literally the only thing I'm good at
Oh gosh this reminds me of the time I was struggling in college lol. Miss G gonna be so furious.
Thinking back about it tho, it might not be that bad after all, the PSLE questions, I think it boils down to student's capabilities rather than the subject itself, like a lot of people said this is unnecessary information and I agree, to certain degree you don't need high mathematical skills until you're like working as a businessman or researcher and so on, basic math is enough to go thru daily lives. At such a young age, what we need is actually stimulation to spark our logical and imaginative thinking, like in preschool it's enough with just looking at pictures and looking around you, entice a child curiosity to know stuff, know names and the like but as we got older such stimulus is no longer enough and we need something more intricate and more rigid. Which is why I believe these kind of mathematical question gives situation alongside them to let the student imagine a certain problem and using a certain set of rigid rule which is math to find the logical solution. For me I think it doesn't have to be math tho, literally any rule works, even in gaming there's certain rule to how we play the game to keep it fair and challenging, like if you play pokemon, you know it's a turn based battle, so your brain is thinking of all kind of stuff like, how many HP I have left, should I attack? Should I use potion? should I switch pokemon?, all these are good stimuli for your brain. I will say kids who play games and do well in it are just as smart as kids who studies a lot and do well in it, based on brain capability. What sets them apart during exam and classes is the "rule" they use. if those gamer kids don't know the "rule" to play the game(math), how can you expect them to do well? they are basically on an away game in that exam hall, if only they knew what they need to know which is the rule, they'll do soo much better. of course I'm not saying better than the kids that actually studies, but that depend on the kids themselves. On that note I'll also touch on repetition, like back in school, a lot of people told me math isn't a subject that you study to 'understand', instead you study math by doing a lot of exercises till you got it. Yeah I agree, after all if we go by my analogy just now studying math to 'understand' it is like reading the game manual without actually playing it, you won't get good that way, but hey in hindsight, if I don't know the rule before doing it, don't you think I'll mess up big time? so please, don't stop people of they're trying to 'understand" math, instead guide them through it by doing a few question with them and allowing them to try their hand on some math. This is like you finding a veteran player to carry you in moba lol, studying really is just like gaming.Which reminds me.. I never touched on repetition like I said I would lol, got distracted, so anyway, what I was trying to say with the repetition thing, just like in moba where you skill improves and get more polished the more you play, the same thing goes for your study as well, so now it's not a matter if you're smart or not, it's a matter of whether you want or not. Btw I never cited any source or anything in this little writing I made, so to prove my point, just look at Katsuragi Keima from TWGOK and Sora and Shiro from No game, No Live, they are all top gamer and excellent study as well. That's all I have for this academic outlook for now, see you later lol.
3:13
Shouldn't this be 7 since the question wasn't "how many ways can you multiply 2 numbers to get 36", it was how many equal groups of people we can make?
If even the answer key is getting it wrong, no wonder people are.
3:32
Let's use logical reasoning here.
We'll assume that since we're talking about live animals, all of these values must be integers.
We know that:
H == 10%
B == 22%
D == 8%
F on the chart has a right angle (as represented by the square) ==> F == 25%
Because of this:
C == 100%-(10%+22%+8%+25%) == 35%
We also know that H + 20 == C
Let's take X to be H:
H == X, then:
C == X + 20
Since we know that C is 35%, and F == 25%:
F == 35% - 10%
F == C - H
F == (X + 20) - (X)
F == 20
Therefore:
n% == (n/25)*(25%) == n/25*20
C == 35/25*20 == 28
H == 8
D == 8/25*20 == 6.4
B == 22/25*20 == 17.6
H+B+D+F+C = 80
Therefore, while in a purely number-based context, 80 may be a correct answer for the distribution of these numbers, realistically speaking, you cannot divide up 80 animals into these percentages, as they would end up as fractions.

This is just a simple linear equation
You have the top side, which is equal to the diameter of 3 circles, plus the 2 times 12 spaces
Then you have the bottom side, which is equal to the diameter of 2 circles, plus the 2 times 22 spaces, and the 16 space
22+22+16+2D == 12+12+3D
60+2D = 24+3D
36+2D = 3D
36 = D
Answer: The diameter of a circle is 36.

If Tessa saved 4, then Judy saves 5.
If Judy saves 3, then Polly saves 2.
We'll take Tessa as the base of our calculations.
If we assume that Tessa has saved 4 dollars, then all the rest of them will have saved the following:
Tessa: 4
Judy: 5
Polly: (Judy / 3) * 2 == 10/3
With the above information, we can create an equation for their total savings. Here, we'll represent the amount of money they have to save to get to the goal as X, again.
4X + 5X + 10X/3 = 1850
9X + 10X/3 = 1850
27X + 10X = 5550
37X = 5550
X = 150
Therefore, Tessa must save 150 for the three of them to get 1850$.
Now convert this value to Polly's savings
10X/3 == 10*150/3 == 500
Answer: Polly has saved 500 dollars.

C started at: 10:00
D started at: ?
At 2 pm, C was 50km away from the city. ==> (10:00-14:00)*75 == 300km travelled.
Total distance between cities: 300 + 50 == 350km
D passed C at 12:00 ==> C travelled 2*75 == 150km at this point. ==> Meeting point A == 150km
After passing C, it took 2 hours for D to reach the city. ==> (Total distance to city) - (Meeting point A) == Distance travelled in two hours == 200
Divide D's 2 hour travel distance by 2 to get his average travel speed of 100km/h
Answer: Daniel's average speed is 100km/h
D started at: ?
The total time necessary for D to get from city X to city Y is the total distance divided by his speed. ==> 350/100 == 3.5 hours.
We know he arrived at 2 pm, so he started at 14 hours - 3.5 hours == 10.5 hours == 10:30 am
Answer: Daniel started at 10:30 am.

Alright, I went back and answered two questions that Jolene didn't know how to answer: 12. (pie chart with hamsters) and 36. (saving money). Here is the correct answers with working. I am also in my first year of university, and I found these challenging, so don't get too annoyed if you didn't get them, it is really brutal for 12 year olds.
*_12. The pie chart below shows the different types of animals in a pet shop. If there are 20 more cats than hamsters, how many animals are there in the pet shop?_*
*This question uses ratios and simultaneous equations*
To start with, the graph is highly deceiving. I started calculating first thinking that Hamsters + Cats = 50% of total, but it doesn't add up right.
The fish is quarter of the graph, so 25%
Adding up all the remaining percentages gives us 65%
100 - 65 = 35% Cats, which means that 35% of the total pet shop is made of cats.
Therefore, the ratio of cats to hamsters is 35 to 10, or 7 to 2 (for every two cats, there are seven hamsters).
To simplify this, let's make hamsters *H*, and cats *C*)
If 2 cats = 7 hamsters, then 2C=7H.
We also know that there are 20 more cats than hamsters, so C - H = 20
We want to have only one variable, and in this case the easiest will be changing the cats.
If 2C = 7H, then C = (7H)/2
Putting that back in to the original equation gives us ((7H)/2) - (2/2)H = 20
This makes (5/2)H = 20, which can be written as (5H)/2 = 20
multiplying by 2 then dividing by five gives us H = 8, which means that there are 8 hamsters in the pet shop.
If 8 hamsters is 10%, then 100% of the animals is Hamsters * 10 = 80
The correct answer to this question is 2) 80.
*_36. For every $4 Tessa saves, Judy saves $5 and for every $3 Judy saves, Polly saves $2. How much does Polly save if the three of them save $1850 together?_*
*This question uses ratios*
To start with, there are two different rates Judy saves. We should make them the same amount. We can do this by multiplying Tessa:Judy by 3 and Judy:Polly by 5.
This gives us the equations of $12 Tessa to $15 Judy, and $15 Judy to $10 Polly.
We can then make them equal to each other, with the equation becoming 12 Tessa to 15 Judy to 10 Polly (12J = 15J = 10P).
This can now be written as a ratio of Tessa:Judy:Polly (12:15:10). The total of this is 37.
In total, they have saves $1850 together. To see how much one part is, we divide by 37, which gives us a nice even $50.
Now that we know one part is $50, Polly's ten parts means that the amount she has saved is ($50 * 10) which equals $500.
The correct answer to this question is $500
Can u tell me how to solve question 16? ( the one at 4:32 ) I am confused about what the straight line means, cuz if it means to divide the height into 2 equal parts then why is it located below the vertex instead of being on it
Correction: Question 13 does not require Ratios or Simultaneous Equations.
First off, you calculate the percentage of Cats in the Pie Chart. It'll be:
100%-(22%+8%+25%+10%)
=35%
Second, because it is stated in the question that there are 20 more cats than hamsters, we find the difference in percentage of hamsters and cats.
That'll be:
35%-10%=25%
As aforementioned, the are 20 more cats than hamsters, so this means that:
25%=20 and 100%=80, hence the answer out of the 4 choices is 2
@@Anna-kz7km to be honest, no idea. Like you I am clueless as to what the line means.
but 22% of 80 is 17.6 birds and 8% of 80 is 6.4
it took me 30 minutes to realize that the number of pets is imprecise
i know 80 is the correct answer though
@@Anna-kz7km Im pretty damn sure they didnt give enough information to even solve the question. I tried it for like 20 minutes and it just doesnt seem to add up. This is pretty likely since 2 questions in the test (the teacher question and the pie chart question) were poorly made. I wouldnt worry too much about it this whole test is garbage
As a Singaporean, i can say this is true and the parents are insane for that
For the semi circle equation you can find the equal overlapping parts and set up the following equations
(leftmost top semicircle) 22 + x = diameter,
with x being the length of the overlap with the leftmost bottom semicircle
(center top semicircle) 16 +2y = diameter,
with y being the length of the overlap with the leftmost bottom semicircle
(leftmost bottom circle) 12 + x + y = diameter,
with with x being the length of the overlap with the *leftmost top semicircle* and y being the length of the overlap of *center top semicircle*
Because
22 + x = diameter
and 12 + x + y = diameter
22 + x = 12 + x + y
Subtract x from both sides
22 + x = 12 + x + y
- x = - x
___________________
22 = 12 + y
subtract 12 from both sides and you get
10 = y
Since 16 + 2y = diameter
substitute y in
16 + 2(10) = diameter
diameter = 36
I wish I could draw a diagram, which would make it a lot easier, but I hope it helped.
I went through calculus at some point in my life now I even have a hard time doing fractions
3:15 If you find the factors of 36, you will find 5 (n * n) ways to get 36.
Since one of them is 1 * 36, which in the question stated should not be included, there are 4 ways.
factors of 36 is not correct for the question. Because multiplication factors assume 2x18 and 18x2 is the same. But 2 groups of 18 people and 18 groups of 2 people are VERY different

I do agree with your sentiment here. I'm decent at math, but at the same time, I don't feel like this is useful when it comes to adulthood UNLESS! If a kid really likes solving math and/or want to be a teacher (of math) or an accountant (or any careers involving deep understanding in math), so since I wanna be a business owner or a business manager, I think this kinds of problems and equations are not really mandatory and necessary for a kid to learn if the kid is not interested in it in the first place. But I do think that basic math is for everybody and that is the one that is very mandatory and it makes sense why people need to know basic math for future adulthood and stuff. I don't see the purpose of learning how to solve deep equations and problems that can actually benefit me in life. This is just my opinion tho.
I respectfully agree, but I hope in the future teacher of math or accountant would not exist at all because AI might be able to do anything related to math. Since ai is good at math and humans are good at using creativity to solve real life problems, the world can become better for everyone.

Let me help you solve the problem number 45 in 6:34
It's called kinematics in physics
a. Clement started his journey at 10 am with average speed of 75 km/h
In 12 pm, Daniel Passes Clement
(12 pm - 10 am) = *2 Hours*
So, Daniel Passes Clement when he driving about *150 km* from town x --> (75 x 2 = 150)
In 2 pm Daniel reach town Y. Clement is still 50 km away from Town Y
(2 pm - 12 pm) = *2 Hours*
So, Distance between "Daniel Passes Clement" to "Daniel reach town Y and Clement is still 50 km away" is *150 km* --> (75 x 2 = 150)
Distance between "Daniel Passes Clement" to Reach town Y for Clement is = 150 + 50 = *200 km*
200 km and Daniel did it in 2 hours --> Average Speed of daniel = 200/2 = *100 km/h*
b. Daniel Passes Clement when he driving about *150 km* from town x
So we know when Daniel started by using this equation
150km/100 km/h = 1,5 hours
12 pm - 1,5 hours = 10.30 am
