There seems to be two. I entered at 18, didn't take a gap year.
I took Maths, Further maths, physics and psychology at AS level then dropped psychology. Got A's.
The STEP exams are the things that count though, for maths. I think I'd still have trouble passing them again.
I got a II on step 2 and a S on step 3.
Grading goes III , II, I , S.
We were required to get a I in both, but I guess the S on 3 persuaded them.
