The Edexcel C4 (21/06/12 - PM) Revision Thread

So just got back home from C3, and am not looking forward to C4, although the plus side is that there isn't as much trig. I have only gone over C4 once on my own and I don't know if 5 days is enough to cover the whole topic (hopefully I will get the annual leave I have requested from work, otherwise I am screwed and will have just the weekend to revise).

Any tips to revise C4 in just 5 days? Although I have been productive during the times I have spent off work to revise. Revised the whole day yesterday and did a few past papers for C3, which helped.

I can relate.

How are you feeling about this paper?

Tough paper.

I haven't done C4 work for a while, but my last impressions/perspective were that C4 is insanely hard. But that was possibly due to the fact that I did not have solid C3 knowledge while doing the C4 course. Today was actually my C3 repeat (C in January...> done minimal work) and I have revised thoroughly for it, definitely got at least an A in it.

My question is for those who have been doing C4 revision for at least a week already (can make good comparison). How much more difficult is C4 compared to C3?

In my opinion it's loads harder.

I found C4 easier than C3 when I was going over it but that's because I prefer integration and vectors are pretty easy. Never liked C3 because of all the trig.

C4 is not that hard, just more complicated than C4, because we need to have synoptic knowledge(C3 needed C2 and C1, but in C4, all C1, C2 and C3 knowledge is required).

Might need some time getting used to C4. Did a C4 integration question few minutes ago (just for the sake of it), and I ended up using a method that can neither be called differentiation nor integration :rolleyes:

They should just give you marks as long as the method works. It's pretty crap that you have to follow their strict framework.

can't believe how hard c3 was today, was expecting a much easier paper, hope c4 dosent follow the trend

They do, as long as it hasn't specifically told you to use a method.

Actually, C4's the first Maths exam that can have truly unpredictable questions. It requires applied knowlege of all the other modules, but it's all easy in comparison to the skills required for C4 such as complicated integration.
Vectors are free marks though, I'll say that much.

Breifly go over the theory for all the topics then loads of past papers. If you get stuck on questions look at your notes on the topic to see what you should do. If you get REALLY stuck look at the mark scheme (generally though I look at Arsey's as it's nice to see it written out).

Hey guys,
can anyone help with differentiating this? my mind's gone blank.

y=4^x - 2^(x-1) + 1

I know the 4^x will be 4^xln4 but i'm confused on the '- 2^(x-1)' part.

Thanks!

Question guys!
If i get the correct answer but hardly any working out, would i still gain all the marks?
This 6 marker here is bugging me :/

No.

Maths is all about working.
