^ if 65 aligns to 98, is it possible to get a 100 exam mark without getting 70?

^ dont think you have to. I dont think that its marked by a computer like the icas competitions.

is my working out correct for the 3mark binomial question. It seems really different to carrotsticks'. Could someone predict what i should get out of 3?

Wow. I wish my school offered accelerated maths.

thanks! I assume that you got 70 raw

how many people do you think will get 70? also will 68 and 69 align to 99 or 100? my friend says 100, but that doesnt seem right? Does it?

its kinda depressing that i'll never sit a maths exam again

looking at carrotsticks and sy123's solutions, so far i know i got q6 wrong. And in the long binomial 3 marker, i got the right answer, but since i rushed im not sure if i wrote n or 2n on top of the sigma sign. I think i already posted this in the general thoughts thread. lol

Thanks!! And thanks to others for verifying my answer

wow that seems like a really low cut-off

Thanks

is this right? I dont think ive made any assumptions about QTP being straight

C d c d a a (damn its b) a d b c

for 11f) did you have to type the actual calculator value or can you leave it as 1/3 (arctane - pi/4).

for q11f) did you write 1/3( arctan(e) - pi/4)

the paper was pretty fun and new. it seemed harder than others. think i got 1mcq wrong, and i cant remember if i wrote n or 2n on top of the sigma sign in 14b)iii). I'm quite sure i wrote n thoughÍ

Im assuming you dont do physics. But if an object accelerates, there must be a non zero force acting on it Edit: saw your sig, i assumed correct:)

oh damn, i was hoping to get 1 for 'working towards the solution' or w/e the marking criteria usually says

what i meant was that for c)ii) didnt know how to show AE=.... using triangle ABD. so instead i used a different method where i had to expand sin(a+b). only afterwards did i realise that the next question c) iii) asked us to 'hence show sin(a+b) =sinacosb + sinbcosa.' So i was wondering how...

i have a few questions regarding marking: - for 13c)ii) i showed the result AE = 2rcosa sinB using the identity sin(a+b) = ... but i didnt see that we had to prove it in the next question. So will i lose 1 or 2marks? - also for 15c)ii) i didnt read the question properly and thought...
