Perhaps surprisingly I happen to agree with both Chaffers and Scroggs, but nonetheless hold to the advice I've already given, it's not incompatible. Don't do something you're not interested in, but if you can't find a degree you're interested in and has some relevance to eventual ATPL training, I'd be surprised.
Maths and Physics aren't essential for pilot training (they are however for many technical based degrees), but they will help if they're subjects that you feel comfortable with and enjoy.
