The 'A' boundary for Jan2010 was 50/72 wasn't it?

Got this answer too, really not confident though seen as it was about the only question on the whole exam that I managed to finish. :frown:

Same, that paper was the hardest one so far. Hopefully everyone's marks should go up in that case.

On the bright side. The retake surely can't be any harder in june :P

I did the Jan 2010 paper; 51/72 for an A.

The June paper was harder; 50/72 for an A.

Thankfully, I scored 91 A in the Jan paper (and an A* overall) and didn't need to resit. Have been doing a fair bit of tutoring/help this year, especially for OCR C3, will be happy to answer any questions or queries regarding C3 or OCR. And if somebody has the paper, i'd appreciate it if they could PM me.

Good luck to all sitting exams :smile:

Wouldn't mind if they put the grade boundary for an A down to like 30/72? that would be nice, although probably wouldn't even end up with that. Couldnt do the first three questions one first try, and I'm good at maths! maths was my A* subject but not anymore!

Anyone know if the uni's find out about resits? i know with some uni's they wont let you on the course if you do a resit, but realyl hwo do they know?

Uni's are not bothered about resits, just make sure you get the grade they want you to get in the end.
