AP - I think you DO meet the minimum requirements. Excluding general studies, you have the A level in computer science, then two AS's in very academic subjects...that adds up to 2 and a half A-Levels. I've got through to the aptitude tests with a similar looking results. In my view you should be OK.
Pandora - Yup exam grades are exam grades but you've gotta know the situation if you want to stop worrting about them and get on with expanding your experience elsewhere.
