    Check mistakes, usualy stuff. If you can do P2 and P3, you will be able to do P1. Try doing a past paper before the test as it is afternoon though...

    Its before P3 so I doubt I'll be too bothered with P1 papers at that point!!!

    For me the hardest bit was remembering how to prove the sum of the first terms for both AP and GP's. Also I think you need to know how to prove sqaureroot over 2 is irrational.

    proving root2 is irrational is in P3 and anyway, it's easy.

    root2 = p/q in lowest form where P and Q are integers
    2 = p^2/q^2
    2q^2 = P^2 therefore P^2 is even => P is even
    q^2 = p^2/2 = p*p/2. P is even and p/2 is odd or even. odd*even or even*even = even therefore q^2 is even
    p/q is not lowest form therefore root2 is irrational.
