    Guys, should I do the rest of the Solomon papers I haven't done or do the R/IAL c2 papers? Which is harder?
    Which is likely to expose you to an different way of asking a question than in past UK papers but is on the mind of current edexcel examiners?
    R and IAL

    The spec is very generalised, they can ask the questions in lots of different ways including ones that you've never seen before..

    C1 was very straightforward yet a lot of people found it challenging because of the way it was set up.

    C2 is going to be a huge *****, but let's hope for easy, time-saving marks throughout...

    That's in the formula booklet, under the C1 page

    Yes. 2013 was an example where a lot of people suffered from having to sit the R papers.

    Do people really think it will be harder than the June 2014 paper. I certainly doubt it

    cool

    when it says independent of 'x' it means there basically should be no 'x' term, i.e. it should be x^0

    so you need to find the point of expansion where the 'x' term and the 'k/x^2' term cancel each other.
    this happens when 'n' = 5.
    so you get: (15C5)(x)^15-5(k/x^2)^5
    --> (3003)(x^10)(k^5/x^10)
    the x's cancel eachother out
    k = 2, from part a)
    2^5 * 3003 = 96096

    I'm nervous. I'm going to sleep early tonight after chilling out a little, wake up at 5 and do some last minute questions (not a full paper). Target areas: learning volumes/SAs of shapes, transformations of sine/cosine graph & practise applications of differentiation.

    Good luck guys. May the odds be ever in your favour

    There is no transformations of graphs on c2
