To anyone reading this: The first time I took the ACT I got a 22, but last February (fourth time taking it) I managed to get a 32. I raised by ten points and it took about a whole school year, but it is possible. Little tip: Science is the easiest way to improve your score. Improve on it, improve your composite.
32 out of?
@maaz ali 36 is the highest score for all the act sections
What’d you get on math. Any tips for math?
I noticed most of the ACT test is essentially testing your reading and comprehending skills. My #1 tip for anyone taking the ACT test in the future is to focus on improving your reading speed and comprehension skills.
Testing tomorrow... hoping for a 37
Yeah im hoping for a 38
How? It's out of 36
r/whoosh
36 is the highest score geniuses😂 and thats nearly impossible. but can be done
cat' slife Issa joke
Tomorrow's my last chance taking the ACT, trying to raise from a 29 to a 33. Wish me luck!
Grace theWriter you definitely can! I raised my SAT from 1340 to 1520 this year and I was nervous af. Just try to chill today so tomorrow you are well rested
Good luck Grace!
Me too! mine is a 29, but hopefully tomorrow's score will be much higher for the both of us!
How do you think you did? Today was my last chance too.
Thanks everyone!! I hope all of you did well. I think it went better than usual, on the science I understood more of the questions but I did run out of time, so I couldn’t answer most of the final passage 😬 but all in all if I can just get over 30 I’ll be content!
I wonder how everyone here from 2 and 3 years ago did on their ACT's.
Taking the ACT tomorrow lol. I am terrified.
Sarah McGuire Good luck, girly.
Yo, me too.
Same here
Sarah McGuire me too 😭😭
It's not so bad. Looks up "10 ACT math formulas you've never heard of" its like a list of 50 math formulas and its soooo helpful. I know its tomorrow but its good to glance at it!
I got a 18 my first time... I have already been accepted into my college of choice and all I want is a 26 or higher for scholarships... test is tomorrow
What college you going too?
For number 58, I found a much easier method to be simply making up your own values for the variables and checking with the answer choices. So for example, let's make x=24, which would make t=2, u=4, and y=42. 24-42 = -18. We can then go along the answer choices and plug in our values for t and u and see if it would equal -18. If we use option F, it turns out as 9(2-4) = 9(-2)=-18, which is equal to what we found before. So you can choose option F.
Of course, it's not the pure mathematical way of doing it, but it certainly saves a lot of time. This strategy of making your own values for variables and checking with the answer choices can apply to many different math section questions on the ACT, and is generally very helpful.
the way the supertutor did it was to explain it to students that dont know how to do the problem. tbh, the variable way is much quicker. this is how i did it
10t+u=x
10u+t=y
10t+u-10u-t
=9t-9u =9(t-u)
for me, this is way faster than making up values, then pluging them in
Yes, F is going to be my grade
thank you so much! I didn't understand the way she did it at all and this makes complete sense, you're amazing!
Actually, for the first question you do not need to know what a geometric series is because after finding the first term, you know the series is infinite hence the name an infinite geometric series. So it has to be less than 30 otherwise the series would not be infinite being just two terms 170 +30 =200. The only answer less than 30 is 25.5 so it has to be 25.5
Random.
big brain
Thanks I got a 39
Hailey Bellaird it’s out of 36 though....?
Nija Williams I got extra credit on it
@@mehaileyb Nice lie.
Sergio Flores no you
That’s impossible
Good luck tomorrow everyone
Peanut Butter u too
Peanut Butter do you know what you got?
“Are you taking the ACT soon?”
Screams- TOMORROW!!!!!!!
As a 50 year old man who never had a real math teacher in his life, I am being forced to learn everything I can about Mathematics before I take the Praxis Core Math Test. Praxis Core and ACT Math are generally the same, though some claim the ACT is more difficult. Anyway, you can imagine the struggle I am having, especially with graphing inequalities, doing inequalities, and inequalities altogether. I can get through the Geometry and Numeration problems, and some statistics, but the graphing is completely new to me, and I don't understand why we have to do that at all.
Finally, I've just received my MA in Special Education, and why I have to learn this stuff is also beyond me. I'll never teach 90% of this to my SPED Students, and why I have to learn it seems ridiculous.. God help me, is all I can say.
I had an English teacher who was kinda the same way.. She was a veteran teacher for like 30 years, moved to a new state, had to do the licence for the new state and had to do that Praxis 1 or something. She passed, so not impossible. Not to take away from your story or anything.
Im hoping to be a math teacher and I need a 25 at least for scholarships in my state.
Taking the ACT tommorrow. I got a 29 last time, and I'm hoping to raise my score. Wish me luck!!
Same here exactly!
What did you get?
Phantom X what did u get?
ACT TOMORROW GUYS WERE GOING TO CRUCH IT!!!!
Crush lol
it's going to crush me ! :(
What did you get?
So you're going to give it crutches?
I paused the video, read the question, selected my answer without watching you solve AND I GOT IT RIGHT I WAS SO SHOOK (I’m the worst at math) then I tried to do it with second one and I just went blank even after you explained it😭😂
Isabella Prada saaaaammmmmeeeee😂😂😂
Isabella Prada with the second one, just plug in two numbers for t and u, such as 1 and 2. So x will be 12 and y will be 21. 12-21 = -9. Now, plug in t=1 and u=2 into the answers and select the one that gives you -9. Boom simple.
Ogden Sikel this single comment made more sense than how she explained it so thank you for this 🙏
Ogden Sikel thank you !!!!!!!! this made a lot more sense !!
Want to read instead of watch? Check out the blog for this video: supertutortv.com/videos/the-hardest-act-math-problems
The first question is totally solvable without knowing the geometric series, if the sum in 200 then the 2nd term has to be less than 30 since the first term in 170, which leaves us with the only possible answer, 25.5
Yeah, the question asks for the second term, not the first. You have to multiply 170 by .15 to get the second term. Answer is A.
I didnt eve learn this "geometric series" thing in Geometry. What gives....
Green Apple in algebra 2
What
the first problem got me mad confused so imma just fail 🤷🏾♂️
Isaiah Deserne freaking same
my exact mood rn
LMAOOOO
same bruh
bruh dat was ez man
I’m an 18 year old senior and I’ve taken the ACT 5 times. 😅 in order I’ve made a 17,17,18,17, and 18. It’s really frustrating making the same scores over and over again. Taking it again in April & really hoping for a higher score!
try tutoring
Taking it tomorrow, trying to score a 22 or higher, last was 21
i’m taking it tomorrow for the third time. i got a 17 then a 19. didn’t study at all either time. not sure how i did better. just luck i guess. i’m trying to cram in studying and tips so i can hopefully get up to a 21 to get into college 🙃
1. 1 Hope you did well
How'd it go?
Anyone else taking it tomorrow
PBA i am😭
meee🤞🙏🙏🙏
Meee 🙏😩
that was a stupid test lmaooo C03
I’ve studied for the act soooo much that I am exhausted. All I want is at least a 29 but it almost feels impossible. Won’t give up though.
Rebecca H what'd u get??
Freaking same!!
I’m able to do these quickly and accurately but only on “good days”. It is almost as if my brain allows me to be a super genius some days and a total idiot on others. I just hope the “super genius” kicks in during the test😄
this is a great channel. great work brook
I just got my score back, i got a 35 xd
Great job!
How 😭
@@faridaamr7360 honestly every ACT test is the same. Once you do enough tests it just boils down to identifying what concepts a question is asking you about.
Thanks,
I probably should do more practice tests
I go to T.M Landry College Prep. I'm a freshman (as of February 19, 2019), and I got a 24 on the English Practice ACT. I read. And SANIC is my savior!
yikes, thats the scandal school lmaoo
i got a 31 first time and saturday is my last time to test for it. i just want a 32
I'm honestly terrified of the Math and Writing sections. I took the ACT in my sophomore year, when I was 14, and got a perfect score in Reading, a really high score in English, and a good score in Science, but I did terribly on Math and Writing. Hopefully prior experience, more preparation, and your videos can help this time.
Got a 33 last time...math was the worst for me. Got a 36 in Grammar, 35 in Reading, 31 in Science, and 28 in Math.
I’m hoping I can get a 35 this time...
How did you prepare for it?
I thought Sequences and Series were in AP Calc BC... and I thought the ACT only covered Pre-Algebra, Algebra 1, Algebra 2, Geometry, and Precalc/Trig
I'm taking it tomorrow, ahhhhhhhhhhhhh!!
I take it this Saturday. I need to bump up my math score at least by two or three.
I take the act tomorrow. I’m doing one day review before my first since it’s free. Then I’m retaking in April and studying for two months. I wanna get the feel and exposure to the test. I also just want to brush up before I go.
Thank you!
7:11 #58 is like old school SAT math problems from the 90s and 80s. It's just basic Algebra 1, but kinda tricky.
FEBRUARY 8TH GANG
I am going to straight up cry ahaha
Yea this is terrible😂ima fail bad
Go to bed guys, this test is designed to trick you, and if your tired that's only gonna help it
Mr. T Fucking hell. There’s some several math or science portion that I don’t get at all.
@@Soulify Filter through the bs and find out what they're asking you. Lowkey its usually just what's the difference between this rock and that rock. It's not a test of what you know it's a test of how well you can read
Tommorow is my ACT
THANK YOU FOR THIS!
Yw!
Our school handed out official practice ACTs sent out by ACT and I actually found an error in the math section. I confirmed that it was wrong with multiple college professors so I contacted ACT about it multiple times, but after saying they'd look into it, they never got back to me.
5:00 "you're screwed" funny thing is I didn't know what it was but still got it right using logic. (often times you can work around things) So after getting A, the first term using relatively simple algebra, you get 170. After that if you think about it, the sum of an infinite series (infinite terms added) is 200 meaning the second digit must be less than than 30 so all the terms can add to 200. The only choice less than 30 is F:25.5.
This is why the ACT is so much harder than the SAT.
Nah the science section is easy so you can make up the points for math. English is pretty easy as well. At least the act is more straight forward
Thatlazykid
Science section is the hardest lol. And what do you mean it’s “more straightforward”? It’s the _SAT_ problems are problems that are more straightforward. There’s barely any time on the ACT to complete any of the sections, and the last 10 ACT math problems are much more difficult than the hardest Calculator math questions.
I think the difference is that ACT math questions are much more wordy and demand more understandings of the mathematical terminology rather than the actual fundamentals of mathematics, which is why I personally find it more difficult.
except for how they always blackout one of the high scores on the science, so if you miss a few and should have gotten one score, you end up with a lower one
Machiavellian Introspection cause the SAT want to see how good you are a test taking
I agree
I’m so happy I took higher math like pre-cal and calculus, I know this stuff!
If these are the 'hardest,' I'll ace the math part. Reading is a completely different story.
I wish I was that good at math, but then again, the reading looks easy.
Reading is hard, that's why this math is hard
They must be hard because the difficulty increases as you approach the end of the test. There are 60 math questions. One is question 58/60, and one is question 60/60.
Same here.
English is where i screw
Thanks I had a hard time understanding when the teacher was explaining
I am horrible with math and I'm taking the ACT tomorrow. Wish me luck because I am going to have to rely on it.
TheAnimeAddict im in the same boat except im studying the morning of lol. Howd it go partner?
how'd you do
How’d it go??
Taking it February 9th hoping for a 30🤞🏽
Taking it tomorrow. We ALL got this!
Captain Sauce yes I hope so
I like your enthusiasm, I hope to score a 22 or higher
Kasey James What did u get??
I haven’t even taken pre algebra
thank you so much i was trying to find this vid since i watched it last year. but i ended up getting 34!!!!!!!!!!!!!
I took in February 2019 these were on there!
Taking the ACT tomorrow ….I'm stressing !!!!!!!!!!!!
Act maths definitely more harder, on my sat math I scored a 790 with barely any practice but when I first started practicing for act math, I got under 30s on math. It took me a while to get a hang of it.
RishBeast1738 how did u get a hang of the math and how long did it take u
It's because ACT math tests your critical thinking skills more. SAT math usually has simpler questions. I did the PSAT math and nearly got a perfect score (I only missed one question) but ACT math I got a 31 , but I missed 9 questions. That was when I was in 10th grade
@@mr.klunee4103 ACT math is actually more straight forward then SAT math. ACT is a bit less time.
@@lefthanded5473 I guess it depends on how you define "straight forward". The ACT in my opinion is very straight forward - 60 questions, 60 minutes. Calculator in optional but not required throughout the test. Very Simple. But SAT Math is more complicated, as a test. The content itself is different. In my experience at least, SAT math is mostly "solve for x" type questions, which can be difficult, but I feel that ACT math tests a wider range of concepts and better tests your ability to think critically about a given situation. I also think that 60 minutes is actually little generous, considering the questions are pretty short and most only take about 30 seconds.
holy shit helped so much and i havent learned any of this (sophomore), but somehow this was super easy to understand. taking ACT tomorrow tho... lol uh oh
Tomorrow is my first time testing it wish me good luck🙏🏼
I am taking the act tomorrow and I haven't even started studying. I guess I like to study last mintute
You'll get a 20 prob.
Nah dude, I have done this last time and got 31
i wish i got a 31 i would be satisfied with that score
Are you taking it tomorrom?
yes but I did not study :/
Can you do the same for SAT? Thanks!
I'm a sophomore in hs and my goal is to get above a 30 on the act preferably a 35 so I'm studying for it now and doing practice questions everyday until the act (if I can)
I study in India and am preparing for JEE mains and advanced.I saw this video for hard problems instead they are the ones i solved in my head and i will be very lucky that this questions come in exams
Gauravsingh Sisodia 😂
Good for you. No matter how smart your country is you still are one of the poorest most incompetently ran countries in the world.
Practice with the first 10-15 problems on an AMC 10 or an AMC 12 (contest math tests)- If you get good at those problems these will be easy.
I'm good at math but on the last ACT I took my calculator was in the wrong mode for the entire test where it needed it cause I forgot to change it. (I think it was in degrees when I needed radians)
I got a 32 with a 34 on the math. My science was bad though.... got to bring it up!
the second one could just be trial and error, take for example 14; you'd do 14-41=27 and just start plugging numbers in and find the first one fits it: 9*(1-4)
How do you find these practice test?
This isn't related to the ACT, but can you make a video on the SAT Chem and Bio (E/M) Subject Tests? Like tips, top need to knows, how to study for it, etc. I've taken college-leveled Intro to Chem and General Chem already if that helps. Pls comment if any of you guys have tips (especially for Chem subject test).
Erika W I took both and earned scores in the 600s. I took dual enrollment bio and chem, but I never took AP. If your classes are college level general chem or bio, it probably won't be enough for the subject tests. The content on the tests are closer to the AP exam from what I've heard. If you're taking multiple subject tests, you could go for the official college board subject test book. It has an official practice test for each subject test. I'd also recommend the Barron's review books, those are great for these tests. If you're taking the December SAT, start studying now if you can. I only gave myself a week to study for either test, and though my scores are decent, they're not great. Competitive schools like MIT will accept scores in the 600s, but they generally expect a 700 or higher.
Summary and extra tips:
Subject tests are like AP tests, not dual enrollment finals
Get test prep books (Barron's or college board) or use free online practice tests
Study as soon as you can, try to start at least 3 weeks in advance
Get used to the subject test scantron (especially for chem and bio)
Time yourself (the tests aren't as rushed as ACT math, but you still need good pacing
DON'T GUESS! Well, you can... but these tests are like the old SAT, so a wrong answer will deduct a quarter point from your raw score. If you can't narrow the answers for a question down, skip it
Good Luck!
got them all right bois,. but I already took act
Oh yea, I’m definitely taking it soon. I’m taking it tomorrow! Ahhh
Diana Salinas same
I couldn't take the ACT junior year due to covid 😒. Taking it tomorrow
got 24 on my previous two tests and about to take my fourth one tmrw. my goal is a 27! wish me luck please ^^
By trying to get 10 extra points on the ACT Math from the last ten questions, you should be golden when it comes to proper college math placement, as many colleges use the ACT Math score to determine course placement without having to go through placement tests or CLEP
I'm taking the ACT tomorrow in February 20, 2019.
Panda same! I’m nervous 😬
yikes test tmrw lets get it
Wish me luck peeps...I got it tomorrow
Saturday ☺️
do the sat have a essay please
it will be so kind of you if you give a try to IIT advance questions
I’m in nine grade and I’m about to take the test .We are forced to get at least a 35 to stay in a college program in my school.
As a ninth grader? When you haven't taken any of the math or science courses required to at least do well? Good luck with that. lmao
The first question is literally what I had to do in math 20-1.
I have it tomorrowwwww
Studying for October 28 😥😯Will come back for my score. My goal is 34.
Best of luck! I’m shooting for a 34 as well
@@haley7642 thank you! You too!
Up at 11 even though i should be resting. Shooting for a 28 (I'm dumb)
what did you get?
Quick question that first question said the sum of a given... Shouldnt you be adding something as sum means 2 things added equal that
I take it tomorrow its 12am help
zachisaloser omg same!!!
ACT tmr time to cram😩
In that first problem what does A represent and how do you know where to place the A in the equations ?
taking my first act tmrw! wish me luckk
how was it?
How was it ? ??!
But I've never learned any of this..
I am always screwed...unless someone above help me
8:55 or you can just plug in numbers for t and u?
lol I was thinking the exact same thing
Monsundo yea I think it's a lot simpler solution
Nope, if you take the number as 90 then the answer can be 9(u-t) and 9(u +t) and 9t- u
@@Karansanghvi72 true but the answer has to work for all 2 digit numbers. If you try 78 for example, 9(u-t) is the only answer that works.
So easy.
Taking mine next month super nervohs
I'm taking mine tomorrow. I dropped out of high school in 9th grade because of personal issues and got my GED. I never learned anything after 9th, I don't remember how to do anything, I haven't studied, and I'm taking my test tomorrow. You'll do fine :) (or you probably did fine if you took it).
Also it's been 2 years since then.
anybody know of videos like this for the sat???
I didn't understand #58 at all
Meow Gaetan same here 💀
Hi, Brooke! I took the new SAT and got a perfect score after watching many of your videos. Can you do video about the SAT Subject Test Math II section?? I know you already did a few, but any new material coming from you would be incredibly helpful! Thanks
David W- can you shed some light on how to get a perfect sat score, mine is on 2nd December. It will be a big help
David W Good job, man.
PIYUSH ANAND what is your current range of scoring in the Math section? If you're at 700+ now you definitely have a shot of getting a 800. Also, are you good in Math, in general? I'm actually the Brazilian Champion in some math international competitions (i.e. I won the Asia International Math Olympiad Final this year). But in my perspective, if you have a good base in Math, you surely can get a perfect score. I'd recommend you to understand what kinds of questions are in the SAT. The test is pretty predictable, so by just using Khan Academy (make sure you practice at least 3 sets of each topic) I believe you can get there. And make sure you took all of the eight official practice tests available and know to solve every question. I personally missed a few on the first Practice Test, but at about the third one I was usually getting all of them right. Hope this could help you, and if you have any doubts about it just let me know!
David W- I am good at maths, I have given 4 official test and got score of 800, the only problem I am facing is in English. I run out of time in critical Reading section and none of my strategy work in the writing section. If I read the whole passage in writing section I lose time and if I just read the sentence, then I make mistakes in arranging the paragraph questions and in the idea that next follows questions. What should I do to time myself? And which books to study from?
PIYUSH ANAND I was exactly in your situation before taking the October SAT. If you are constantly getting 800 in math in your practice tests you will likely get a perfect score on the real test, just make sure you spare some minutes at the end to review your answers. I'm also not very good in critical reading, but I can say the most important thing is finish in time. Don't spend more than a minute in one question. If you're stuck, choose an answer and move on. Maybe you can come back at it later (but probably not). It's ok to miss a few, you will "compensate" with your math score. About the Writing section, I'm actually pretty good (miss just 2 on my exam). Try to grasp the main ideas of each paragraph and also highlight the subject of the sentences that are questioned about. By using this strategy, I was able to improve my EBRW score from 630 to 720. A bought some prep books but I found my self learning more on Khan Academy. Practice all available reading sets, and try to pace yourself. I think that's about it
Oh god. U saved me just in time
How’d you do?
Also, please don’t take the Lord’s name in vain, thanks
I hope I get a score of 30, but probably not I'm slow at things like I take my time, that I need to learn how to do
I wish I had seen this before I took the ACT...
Good luck to all ACT aspiring bois
Feb 9 2019 anyone?
Where did she get the 9t-9u from? Everytuing was 10
I found these so easy, but I am not from the US so it might be due to the different curriculum and syllabus, these things were taught in my country in 8th grade early 9th grade so yea....
Im in 8th grade and I got #58 right!! Yay got the first one wrong though!
