Choosing A-level subjects

Can anyone help me with choosing right A-level subjects for studying law at university?
I'm taking Geography and Further Maths, and I want to do one more subject either Biology or French. I like French better but I haven't studied it in GCSE...
Is A level French difficult compared to Biology? Which one is better for applying university?
Thank you😀

History. Languages tend to be HELL at A Level (from what I've heard). Biology would be a good choice. History is your best bet and Geography will help. What about English or Film Studies or Sociology. You'll need some more essay based subjects. Give me your full list of G.C.S.E.

Thank you for your advice. I thought about taking English Literature and History at first, but because I'm an international student(from China), they will be very hard for me...and I didn't take GCSE.

What did you take at G.C.S.E. equivalent then? History shouldn't be a problem for an international student. What about Film Studies or Sociology though. You need something essay-based
