What is it to get a C?

If 90 is a B, do you think the boundary for a C will still remain as 56?

What's the grade boundary for a c?

For these particular papers i would say a C grade would lie around 80/200
so around 40 in each paper

Remember this is only an estimate, this may or may not be the case when the grade boundaries are decided.

Unlikely, way too high. I would probably say the boundary for a C would be 60 or lower.

Nooooooo no way. 40% has been a low/mid B normally!

No way. Please don't estimate from how you personally found it!

i presume this is out of 200... it really depends on how the country did, however the fact that its a new spec may turn about to be a good thing because people are not used to it. Compare the papers with 56 as the boundary with how you think you did on the real papers...

but in gcse isnt it 80 % an a*

I think they will be similar but lower as you say no has that much experience in this new spec and then it will steadily increase every year as theres more past papers available. i think it will be around 112-1120 for an A and an A* around 134-152.

i think just what i think .
non cal : out of 100
A*-67-73
A-60-65
B-53-60
C-38-48

I don't know but thats what i think might be. only my view it is defo not correct as papers have not been marked

wow! 143-152, for an A*???, thats quite low, no?
i thought it was normally 85%, so ive been told, that makes around 170
