    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,

    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.

    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.

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