# Edexcel A2 C3 Mathematics 12th June 2015 watch

1. Does anyone think that June 2013 wasn't that hard? I found today's much more difficult!

You are not the only one man, this exam absolutely ****ed me. Was expecting worst case scenario a B, but now I am lucky if I get a C.
3. How many marks will I lose if i wrote ln.5 instead of ln2
4. Late to the thread. There an official markscheme yet? Arsey was pretty quick with S1 but not sure if he/she does all of them.
5. **** EDEXCEL IT WAS MY LAST CHANCE TO GET AN A*!!!!!!!!! UCL AND KINGS COLLEGE OUT OF THE WINDOW

(1) guys, if in 9c, if wrote this: k is negative and therefore -3x-k = 3k and therefore 3k is greater than 0 and therefore it is increasing. is that right for 2 marks?

(2) and do you think that with 65 would be enough for an A*

cheers fellas and I feel ur pain !

If you showed your working out to get ln2 and just miswrote the answer you should only lose 1 mark otherwise it depends on what the question was worth - I can't remember

I just don't understand what was the need to make it so complicated? In past papers I've been getting 73+ and in today's exam I literally felt sick because of how hard it was

All my other exams have gone badly as well -___-

Okay

Also,
if you give more than one answer outside of the range do they ignore them or.. ?
9. Can I get a few people's opinion on something?

If the question says, 'State a reason why the function g^-1(x) does not exist'
And I put, 'It has a one-many mapping therefore it cannot be a function.'
Would I get the mark? My 'It' is clearly referring to the inverse because that's the 'function' they're asking about in the question, but would they penalise me for putting 'It' instead of 'g^-1(x)?' It seems so unfair because that's the one they were asking about in the actual question!

You'll receive full credit, I'm sure. At the very least, you'll receive BOD.

Thank you!
12. 53 = B grade boundary?
13. Arsey and TeeEm's grade boundary predictions are sounding lovely

to get A* you will need 180 total in C3 and C4 (so long as your grand total is at least 480). Although it would have been nice to score higher you might fing that your C3 is roughly at 90UMS, so A* is still there
17. (Original post by TeeEm)
these are my estimates

100% around 70-71
90% around 63-64
80% around 56-57
70% around 50-51

I cannot see these boundaries any lower ... let us hope they are not any higher
oh my this has given me hope
that sounds delicious
it will not be far off that figure
19. I drew instead of the exponential graph a graph of lnx cause I'm a bit of an idiot. I still had the right points at where it crosses the axis and for part b) I drew it correctly for my graph. How many marks out of six do you think I will get? Sorry but I need to know if I would get like two or three marks?

thanks i got a min of 53 (without method marks or ecf) so im really pushing it for an A (or high B)
