why is it so simple when you do it but then so difficult when i try?? if im stuck all i need is to see the first thing or two which you write down and then i can get to the end of the question independently. but when i do it all entirely by myself i get nowhere 🤦♂
Hi sir for question 19 when you do 2(6C4) * 1^4 * (2x) * (3x^2) specifically 48:40 You say we flip the order e.g we could multiply four 1s, one 2x and one 3x^2 or we could multiply four 1s, 3x^2 and 2x thus we multiply the start of the choose function by 2 However, im confused because couldnt we have more combinations of orders e.g multiply two 1s, one 2x, two 1s and then one 3x^2 three 1s, one 2x, one 1 and then one 3x^2 ... So why do you multiply by 2 and not take into account all these combinations?
the grade boundaris were very high for this paper (i think you only needed 15 for a 9.0). is this just because this was one of the first papers, or is it because the paper was particularly hard?
if its any consolation, i havent really seen a question similar to it in any other tmua papers. its an awful question, i dont know HOW drew thought of drawing the plan of the shape ;(((
hi thanks for all the videos! i was wondering if there are any specific graphs were meant to know because question 10 requires 1/x which can be worked out eventually but takes up a bit of time, but obviously once you know will save a lot of time. 🙂
off the top of my head in my practice its your sin/cos/tan graphs (also y = sin(2x), why = sin(0.5x) etc). 1/x graph, quadratic (pretty accurately), cubics / polynomial^(odd number) roughly and general exponentials
Practise. You've done amazing to even start prepping for this so early, just practise practise practise. Eventually it'll come easier, but as you can see I still struggle on a coulple of things here, and that's fine too, you don't need 100%
@@Ziyanasto It's hard to diagnose the problem when not seeing it. But general advise: Lay out working in a super organised way, just like I try to do in powerpoint. Don't jump around the page or skip steps. The practise of looking for mistakes is certainly valuable though, so that's a silver lining. The more you look for mistakes the faster you get at finding them. I know this since I spend way too much time looking for them when I mark students work, but had the side effect of making me miles better at finding my own! Just keep at it.

Just needs practise
Sir, for Q20 how are we meant to know to draw the net differently to see that the y route is shorter than the x route?
q5. how do we know when they want us to cancel out the negative area, or effectively make it positive and then just add it on??
these seem easier than the actual papers
It’s the 2016 paper

Hi sir for question 19 when you do 2(6C4) * 1^4 * (2x) * (3x^2) specifically 48:40
You say we flip the order e.g we could multiply four 1s, one 2x and one 3x^2 or we could multiply four 1s, 3x^2 and 2x thus we multiply the start of the choose function by 2
However, im confused because couldnt we have more combinations of orders e.g multiply
two 1s, one 2x, two 1s and then one 3x^2
three 1s, one 2x, one 1 and then one 3x^2
...
So why do you multiply by 2 and not take into account all these combinations?
the combinations do not care what order the elements come in. "two 1s, one 2x, two 1s and then one 3x^2" is already covered by one 2x and one 3x^2
Hi sir, for q15, I was wondering why you differentiated with respect to x if the question says a is varying?
the grade boundaris were very high for this paper (i think you only needed 15 for a 9.0). is this just because this was one of the first papers, or is it because the paper was particularly hard?
How the hell are you meant to do question 20 in under 4 minutes???
you pray to the lord and then start the question 😭🤣🙏

Where have you seen a question like question 20
Sorry, I really don't remember, I've done a lot of random maths

For question 20. Why can’t we go through the pyramid straight from p to m, I did that and got the same correct answer
You have to go along the outer edges I made the same mistake it says in the question

are we supposed to memorize trig graphs and values since we arent allowed a calculator?
Yup, you'll need to be comfortable in both radians and degrees and you'll also need to be able to find further values like sin 330 with some method
@@rtwodrew2 would we need to know inverse trig graphs?
@@LK-sk9wl to my memory theres never been a question requires knowledge of the inverse trig graphs.
Its fine in the beginning, but then I don't even know where to start with questions

@@rtwodrew2 I watch your videos, try do the question, but then get lost in my own working. I keep having to look back where I went wrong.
