So my problem is-

CIE- I got 62 in Paper 1 in Maths and 31 in Paper 6 in AS LEVEL . The grade threshold for A in Paper 1 was 58 so i got A

and in Paper 6 it is 32 so I got C. Overall B . My total was 93 and for A grade threshold was 96 so is it because of 3 marks i got a B ?

In A LEVEL according to 2012 may june mark scheme A GRADE threshold is 188 so for 2012 oct/nov Grade threshold for A would be around 188 according to the difficulty of the paper. It my be 198 or may be 178 (assumption ). So take it as 188

So would i need total 188 marks to get an A. 188-83=95 so if i get above 95 in A level papers would i get an A ??

Is it the same for chemistry and physics ?? I got a C(Paper 1 ) B (Paper 2) C(Paper 3) in chemistry in AS LEVEL Overall B . If i get an A in Paper 4 and Paper 5 and if my total sum of all the papers is above the threshold grade for A ? Would i get an A ??

Thank you for patience to read this and replying to this. Thanks Hope you reply
