Which are better A-levels?

Hi, i'm doing Art, Biology, Physics and French for A2. I haven't decided which subject to drop, or even if I should. I would like to do Biology at either Manchester or Leeds. The grades required are AAB or ABB. I'm predicted A in bio; A in art; C in french and a C in physics. I might be able to get a B in French if I drop physics but UCAS says that I have to have two science A-levels ( I wont be able to get a B in Physics as the maths is too complicated ) would I be able to secure a position of AAB with AACC? Many thanks
