What should my A-level subjects reflect?

Hiya, recently been really stressed on coping with 5 a levels (including FM) and now I'm regretting biting off way more than I can chew. I'm looking to study architecture or game design at university; was thinking of dropping further maths and physics, being left with Fine art, 3D design and Maths. The former because I found out from some research FM is useless on your application for design-based courses if you attain a low grade and the latter because I cannot for some reason get myself to understand much of the course, wasting so much time on it pointlessly revising, time which I could have spent on my portfolios which I actually enjoy doing!
So I wanted to ask you guys if it's feasible for my getting into a decent uni (Bath, UCL, Nottingham and dare I say Cambridge) even if I dropped physics. I understand this may seem like a pretty juvenile question; I'm a first-gen immigrant in the UK, so my parents know about this even less than I.
