5th A-Level Choice?

Physics would be difficult without A Level maths...

Not sure if this should be in the Angst thread - if so please move it there

I'm currently in year 11, and am trying to decide upon A-Level options. I'm fairly (~90%) sure that I want to pursue a medical career, after extended work exp. placements, obsessive research, and personal experience as a chronic patient. However, I'm also aware that a lot can change in 2-3 years, so I'm trying to leave my options open. I could possibly imagine doing a modern languages degree - about the only other course I could summon anywhere near the requisite enthusiasm for. I achieved 7 A*'s and 4 A's in my mocks, and my predicted grades are straight A*'s.

My definite choices are:
- Biology ()
-Chemistry ()
-French ()
- English Lit. ( )

However I'm struggling to choose between these 3 for a potential 5th:

- Physics; I haven't enjoyed the GCSE, and I think my maths (was only an A in my mock) could hold me back. However, if this could give me an advantage in medical applications, and not make me seem too biased towards arts, I'd be willing to put the work in.
- Spanish; I'm a very strong linguist (arrogant as that may sound), and I think this would be a RELATIVELY easy pick. However, it's relevance and potential to make me seem too skewed towards languages concerns me a bit, although it is the subject I'd most enjoy.
-Latin; done well during the GCSE, course looks interesting, more unusual/acadmic pick (?) and nice small teaching group! Again, same concerns as with Spanish.

So basically, what I'm asking in a hugely roundabout and pontificated way is, which choice would be best? Does not picking physics put me at an UNOFFICIAL disadvantage for any medical schools (I know its only a requirement for a veryh small number). Finally, will taking 3 arts but only 2 sciences undermine my application for medicine?

Thankyou so much for reading such a massive post and in advance for your help!

Umm, you got A in your maths mock and you think thats bad? I got a C and I ended up top in my year for the real thing. Don't pay any attention to mocks Anywho, physics. Although, consider maths if you do well in the real exam because it'd serve you well when applying to uni

Thanks for saying that it makes me feel x100 better about my mocks

I got 9 Cs in my mocks and I came out with 6A*, 2As and a B. I really wouldn't worry about them at all. No one works to their full potential for mocks but not only that but teachers generally mark them very harshly so that you work even harder for the real thing. At my old school, the general rule was that you would go up two grades at least in the real thing Good luck.

I ALWAYS discourage anyone from doing 5AS/4A levels, seriously, not good,
I only did 4 AS's and 3 A levels and i've got an offer from oxford for medicine, doing a 5th AS or 4th A level means zilch, seriously, focus on getting your GCSE's done to your best standard (which is pretty damn good, as it seems), and don't make it unnecessarily difficult for yourself.

edit: and as mentioned above, mocks mean nothing, i got mainly Bs and Cs in my GCSE mocks
