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 :frown:

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?

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

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 :smile:

In previous years what was the average raw mark required for 90 UMS? Also how many marks would I lose for leaving the 0.5cosec4y question as 2cosec4y by accident, 1 ?
