    For the trig identity question part b, did you have to rearrange for a tan quadratic and then use the quadratic formula to get the solutions for tans?

    Do you think full marks will still be given to 0.5 ln 6.75?

    We were working out the x value and the x value had to be between pi/4 and pi/2 :/
    ah that does make more sense I guess, because all the solutions would be in the range -pi/4 to pi/2 wouldn't they, looks like that's a mark or 2 dropped

    Yes using 1 + tan^2(X) = cosec^2(X)

    480 UMS in total across 6 units. Doesn't matter if you didn't get 80% or more at AS as long as your total is 80% or more.

    Dunno why some people come on this thread literally just to say 'exam was easy'. Does it feed your ego? or?

    You need to average 480 / 600 ums in all 6 modules; or average 80 ums on every module.

    If you got 78 ums overall in AS, you need to average 82 ums in A2 overall to get an A overall.

    Don't worry, looks like overall people found it tricky so it shouldn't be a big deal
