Did I do wrong, choosing these GCSEs ?

So I am 2 weeks in my GCSE course and I am beginning to think that I didn't choose the right subjects (music, P.E. and French). I am thinking that music wasn't right for me. I am interested in physics and maths for A-levels ,so will this affect my future in A-levels?

Any advice will help.

You will be able to take Maths at A Level regardless. Whether or not you can take Physics A Level is dependent on your school, some require Triple Science GCSEs which is sometimes an option, sometimes not, you will have to check.

If you're thinking of swapping, better do it sooner than later! It'll be harder to catch up with missed content the later you decide to swap.
What would you swap music for? Physics? If you're not already doing physics gcse then I would definitely swap to that.

If your don't love music, save your self a lot of time, sweat, blood and tears by not doing it.

As you will still be studying combined sciences, providing you get a high enough grade, you will still be able to do physics at a level.
