Here are my preliminary solutions guys :)

I didn't check them, so I may have a few mistakes, but based on conversations with guys who did the exam they seem correct.

P.S. I have a blank copy of the exam too, so I'll upload that next.
Thanks
Damn... I lost so many marks

While you guys blow up, I've got a blank copy with me - now that I don't need to scan it, I'll do it on the train and get back to you. :P

It does look moderate in difficulty - I reckon anything above 60/80 could be an A. Particularly with that last question being worth almost 1/4 of the exam.

I may be subject to exam bias but I found it to be the second most difficult exam to date only succeeded by 2010s cone of death.

I was very pressed for time and there were lots of opportunities to make silly mistakes. Lots of algebra and time consuming things like expanding integrals. The the area under curve question was really dodgy and just urgh. If they had specified it was between the turning point and the left end point it would have been a lot less ambiguous.

Hopefully a better exam 2 will follow.

Urghh... could have done so much better if I read the questions properly. Area question in 5c I bound it with the y-axis and the final question I completely forgot about endpoints :(

wasn't ridiculously bad but I felt it separated the boys (me) from the men (you guys) with the final two questions

FUCK just realised I forgot to simplify a few answers... is that bad?

So quick question guys,
According to the answers everything was right except for my rule for f(x) from f'(x) and f(pi/2)=1/2
I accidentally wrote 1/2 x Cos(pi) = 1, not -1, so my c value came out to be -2 instead of -1.
Will this cost me 1 or 2 marks?

m was 5ln(2) but would ln(32) be accepted or does it have to be simplified
