At GCSE I got a 6 (B) and was 1 mark away from a 7 (A). A lot of courses I've been looking at asks for a 7 at GCSE if you don't do A-Level Maths, including Geology at Imperial, Account/Business etc at Durham, and Economics at unis that don't require A-Level Maths.
So, instead of me sending them a sob story about how I was 1 mark away from meeting their requirements, should I do Maths as an AS to make up for it? I don't want to do it as a full A-Level as I feel that I will get a better grade in something else, so if I do it at AS it won't affect my A-Level grades and has half the benefits of A-Level Maths I guess? I'm also doing Physics so AS Maths will help with that as it includes mechanics. Also, I feel that Maths will help me in the real world when finding a job as Maths is such a useful skill, if only I focused on it more at GCSE.
