from units 1 and 2, out of 60, and unit 3 out of 38, can anyone tell me what is required for A, B, C.....
Take 80% as an A. Therefore 48/60 and about 31/38. However, that is UMS not raw, so even if you felt you have got less that, with moderation it will probably go up.
In june 2003, it was:
unit 1 - 38/60 for 80% ums
unit 2 - 40/60 for 80% ums
unit 3 - 50ish/70 for 80% ums
(obviously each grade is 10% raw less than an A, eg unit one was 38/60 for an A, 32/60 for a B (70% ums))
The June 2005 report showed it to be roughly the same, i would hazard aguess to say that for A's in the upcoming as's it will be between 38 and 42 our of 60 for 80% ums on the first two modules, and roughly 50 out of 70 in unit 3.
It's impossible to tell exactly as it depends on how well people do and how hard the paper is.
