Boundaries will definitely be quite high but not 72 for an A* IMO. I would go for 70A*, 65A, etc...
yeh I agree - c4 is a hard module for a lot of people - the integration especially was quite involved using identities and substitution ect where people would've lost marks tbh
the highest grade boundary for the JUNE exam period for C4 was in June 2012 when you needed 63 for an A, so judging by this I can't see it jumping that much higher than 65
Thank you, i was being paranoid i think but can never be too sure about marks and people on TSR saying sky high boundaries etc. Thoughts on boundaries for c3?
What do you think the C3 grade boundaries will be ?
I think people are mixed whether or not the c3 paper was harder than last years. Last years did have a killer trig question, but did also have some easy questions wheras this year even the simple topics had fairly tricky questions (q5). It was also significantly longer and more of the questions required writing our lots of lines of working than last years paper. It did have a copy paste question but it was only worth 7 marks or so.
My guess is A - 58, A* - 65, 100 UMS - 73. If not 58 then 59 for the A.
Two reasons: (1) when you take -5/2 to the other side it becomes +2/5, not -2/5. (2) when you take x to the other side it becomes 1/x, not x. So you needed to integrate 2/(5x) on the left hand side, not -2x/5.
