So i have pretty much terrible GCSEs compared to most people (Bs/Cs), i messed around a lot after my GCSE's and finally fixed up around 18, now i'm in my second year of a levels (A2) studying A level maths, chemistry, economics, AS Further maths. I achieved AAAA in Maths chem and economics and biology (AS) but dropped biology. Now your probably wondering why i didn't take further maths from the start if i had the intention of studying maths, well i did try to but the college didn't allow me to as my GCSE maths grade is a B (this was 2 years ago...) and they thought i wasn't capable enough, but i think i am, and they now think i am so they're allowing me to take it to AS. Looking around forums, reading about mathematicians etc it seems like they all had perfect grades in mathematics, and everyone has A2 further maths, and i'm just here with my AS (predicted A and A* in regular mathematics). So with all my qualifications, the lack of further maths at A2 would i really be capable for a mathematics degree at a good university (i'm hoping to go around top 10 for maths UK, top 50-100 world (hopefully))? I really do love mathematics, the only reason i got a B at gcse is mainly because i didn't do anything at all, and have stepped up my game at a levels, but every other good mathematicians was good throughout their life, and i just feel like a failure and not capable at a good university (I want to go to kings/nottingham/york). Let me know what you think... thanks.
