Not checked jan 2006, but think june 2015 was 49 for a B quite a hard paper, but jan 2006 was very easy, could of easily got 70 if i learn the midordinate rule/simpsons rule,


So that explains the differences in scores then, doesn't it?

Well, yes but i find that older papers are generally a lot more easier than recent papers.

Sketch the graph and just think for a bit. If e^(3x) is always positive then 5 - e^(3x) is always 5 - (positive number) which is always smaller than 5.
Does anyone have harder core 3 papers/ questions? Ive done all the past papers before 2014 and 2014 and 2015 are the harder (aqa seems to have made the papers more challenging from 2014)? I want to practice more harder questions?
thanks

Try some of these practice papers made for AQA. The functions questions especially are a lot more difficult than the past paper ones

Just go over to the C3 section; even though it's for edexcel I'm sure you can navigate your way around. Papers S and T are very difficult; and I got 100% in my mocks lol.

You don't really need to "learn" those rules, just check your formula book.

Have you heard of the XMCA2 papers? They are very difficult to find but offer some hard questions. I managed you find one of them here

Just differentiate tan⁡4x\tan 4x twice and make use of the rule sec⁡2A=1+tan⁡2A\sec^2 A = 1 + \tan^2 A
