Ok so I would have to say that I'm predicting this year for A2 to be a big step up, we have just started learning the core 3 content. What I want to know from you guys is (really for OCR), What do you guys find to be the hardest chapter of core 3/core 4 and why? What do you wish somebody had told you about A2 maths going into A2? Any answers are appreciated, I ask this purely to prepare myself over the summer holiday and work upon the things that I may be likely to struggle with. Any chapters from those top notch mathematicians would be cool too because, eh, if you struggled with it, what hope do I have?
Thanks in advance!

Hi there,

While you're waiting for an answer, did you know we have 300,000 study resources that could answer your question in TSR's Learn together section?

We have everything from Teacher Marked Essays to Mindmaps and Quizzes to help you with your work. Take a look around.

If you're stuck on how to get started, try creating some resources. It's free to do and can help breakdown tough topics into manageable chunks. Get creating now.

Thanks!

Not sure what all of this is about? Head here to find out more.

I did edexcel 2 years ago, so I'm not entirely sure how much crossover there is between the specs, but the things I found hardest at A2 were:

Trigonometric rearrangement proofs (show that this mess of trigonometry on the left is equal to this mess on the right).
Setting up and solving contextual first order differential equations.
A few of the later integration techniques can be a pain to spot.

I'm doing A level maths atm (C1/C2/C3/C4/M1/S1 this year) on OCR. Whilst going through the content, I hated C4 integration and implicit differentiation; there was no particularly nasty topic in C3 as a whole (in my opinion), but a lot of my friends hated the trig content. However, looking back (C4 tomorrow ) everything is fine, and C4 vectors are probably my weakest topic. Once you get your head round all the integration stuff, it's a cakewalk.

With regards to advice, it is definitely a lot harder than C1/C2 - both the actual content and the question technique. Especially in C4, questions that require more thought and problem solving are common when compared to AS modules. Whilst studying ahead is good, it didn't work very well for me - I looked at, for example, the integration chapters (C4 chapter 5 I believe) and essentially **** myself. However, when we went through it in class, I had no problems at all. What you must do though, is keep up with the practice questions - chapter review type things are very good. Writing notes, and doing past papers as you go, also helped me a lot. Moreover, I found learning things like the C3 trig identities (Chapter 3) and standard angles ((cos(pi/3)) etc) very useful; whilst during C3 it seemed like a waste, when we hit C4 and started doing calculus on trig I found it helped enormously. Finally, make sure you have a good grasp on C2 basics - power rule integration, logarithms, solving basic trig equations and the like - as otherwise you will really struggle with some chapters (C3 ch2 is piss easy if you are comfortable with logs, but a nightmare otherwise)

Regardless, my best tip is to not let yourself get bored with it; I will admit that some of the content (that functions chapter in C3 -_-) is dull, but if you switch off and don't learn it, you will be screwed for later stuff. Finally, if you get a choice of applied units, avoid anything with a 2 in it (excluding D2), as it is about a million times harder than M1/S1/D1

Thanks very much to both of you ^^ very very grateful!
