Yes. Music plus a minor or double major in X, where X is something hard.

Not business -- you can pick that up in grad school if absolutely necessary; they have special graduate programs just for it.

Physics, chemistry, biology, mathematics, statistics, engineering.

But this is the UK we are talking about and the university in question is Oxford - so the rules are somewhat different.

Thanks for the advice (and others suggesting the same thing), I think minoring in Maths is definitely something I'd consider, happens to be another area I'm interested in (though no-where near as experienced, would have to do a fair bit of pre-university learning to be ready to study it I think, having forgotten most of what I knew when I was 16)

This made me smile a little bit; I majored in Math because I thought CS would be too easy.

I was a math major too, but no way would I consider CS to be too easy.

Note the past tense.
