    Wohoo. Piece of cake! Everyone said it was pretty hard except a few, the hardest questions were:

    2sin x tan x = 3
    find all values of x within the range 0 < x < 360

    and one part which required to prove that

    3√x + 12/√x = 9√2
    when x = 8

    pretty tricky for P1, but I got it after some manipulation.

    ahh, the relief!

    3√x + 12/√x = 9√2

    3√8 = 6*0.5*√8 = 6*√0.25√8 = 6√2

    12/√8 = 3(4/√8) = 3(4√8/8) = 3(2^2*8^(3/2)/2^3) = 3(2^*7/2)/2^3) = 3√2

    6√2 + 3√2 = 9√2

    2 sin x tan x = 3
    2 sin x (sin x /cos x) = 3
    2 sin^2 x = 3 cos x
    2(1- cos^2 x) = 3 cos x
    2 cos^2 x + 3 cos x - 2 = 0
    (2 cos x - 1)(cos x + 2) = 0

    cos x = 1/2

    x = 60, 300

    I got a U in my first P1 mock, I got 83% in the actual exam though. Mocks mean absolutely nothing.

    No, when I first started maths I was just...rubbish, Id scraped a C at GCSE and begged to be let on the course, my teacher let me do it and everyone thought I shouldnt of been allowed to do it, I was just really determined to prove everyone wrong. Now Im by far the best in the class - determination, hardwork, and I guess a little bit of talent is all you need.

    Well Done. That is a superb turn around.

    If that is 97% raw, then that would get you 100% UMS.

    You have no need to worry - your gunna rock P1.
    UMS is a standardised mark across the whole country - its the method the exam boards use to f*** with your results. You can effectively end up with 100% even if you only get like 90 marks out of 100
