Rank your A levels from EASIEST to HARDEST

Wow, very nice! My dream is to do medicine at Oxford (or any good medical school for that matter) and I'm contemplating whether to Chem, Bio, Maths + Physics or Spanish for my AS. I think i would be more comfortable doing Physics, but I don't know whether it would put me at a disadvantaged due to the lack of variety in my choices. Furthermore, i feel that spanish would be the only subject out of the sciences that i would have any chance at as I am not very good at english (i got B's in GCSE lang and lit) and I didn't choose geog or history as my options for my gcse's so i wouldn't do to well in those subjects. In GCSE spanish i think i will get an A*, however, u don't really need to be good at spanish to do well in spanish for GCSE.

So, my 1st question to you is, how hard did u find spanish and how did u revise to do well in it? and my 2nd question is, do u think i would be better off doing the subjects I listed +Physics (as i am more comfortable with it) or +Spanish (as it will increase the variety of my subjects and i think i might be capable of doing well in it...maybe =S)?

I know this may seem out of the blue and u don't have to reply if u don't want to, but your feedback would be highly beneficial =D
