I currently take biology, chemistry, physics & English literature. My past school was not at all good; while I achieved GCSE grades that have never before been attained by someone at my school before, the school inadequately prepared me for my A levels by leading me down the wrong paths for my studies. No one got their predicted grades last year.
I have moved schools, with the same subjects and doing the first year of A level. However, maths isn't exactly my strong point, and A2 physics is proving to be difficult for me -- especially as my mathematical knowledge only really goes as far as GCSE. I have spoken to people about my mitigating circumstances and have contacted universities. I know I am at a disadvantage already, but it isn't impossible for me - even Oxford told me this. I understand that A*A*A* will look better than AABE or something like that.
I want to know if taking three A levels (two of which are scientific subjects) will damage my seemingly already damaged (but again, not possible) chance of studying at Oxbridge (and/or Imperial, Kings & Durham).
