Hi,

I've tried to find the answer to this question, but can't find a conclusive answer. So I know if you do S1 and M1 as your additional modules you only need to get an average of 90 UMS in C3 and C4 to get an A*. However, my teacher recently said if I'm doing S2, as it's an A2 module, I'll need to get an average 90 between S2, C3 and C4 to get an A*. Can anyone confirm or not if my teacher is correct?
