So I'm currently studying A2 Maths, Physics and Further Maths, continuing onto M3 for my A2 Further Maths. However, I'm finding it very difficult at the moment. FP2 & M2 have been relatively easy. I'm struggling on elastic strings. I was just wondering, does it get harder than this? The questions they ask in the book are very hard and the thing is, the examples they give are so simple and don't properly prepare you for the questions. I got an ABB last year, the A being in Maths. Are exam questions easier than the book questions?

Any help would be great ! Thank you.

So what would you say is harder, Chapter 2 (Elastic Strings) or Chapter 3 (SHM)?

3 - SHM specifically - the rest of 3 is fine

SHM, but it gets easier with practice. The rest of it is straightforward. You might want to practice COM from first principles as well.

Circular motion!
Circular motion isn't usually too bad, it's just conservation of energy and resolving most of the time!

Totally agree ^

Tbh I found M3 insanely difficult to self teach (maybe because it was the first non-trivial module I self taught) but when I started doing past papers it was nowhere near as hard as I found it at first

PS nice one with the S1 model answers - saw p&mtutor tweet about it :3

Not sure why everyone finds the purple chapter hard.

Only part I found difficult from that chapter was remembering that

 G = \dfrac{gR^2}{M}

 F = \dfrac{gR^2m}{r^2}

I still find mechanics harder that pure though.

This was completely my situation! I think it's because the Edexcel book has some crazy problems and is inconsistent with the difficulty? I still find COM in M3 easier than COM in M2.

Thank you, I'm thinking about doing M2 as well. It was an interesting way to begin my weekend.

Yeah for sure lol - or at least learning it. Because there are just formulae which make sense in M3.

Haha go for it xD

So am I the only one finding chapter 2 questions difficult? Also, the books questions are crazy hard ! Are the exams of the same degree of difficulty?
