Advise me on choosing university course

I don't live in the uk but i'm thinking of studying there. Thing is i'm in year 12 and I have no idea what i want to do but I really enjoy studying. I'm currently doing ial as chemistry, physics, maths, biology, spanish and global perspectives but I'm dropping biology and global perspectives next year to do as further maths. My predictions are all As and a b in biology. I like physics.
