Do I have a chance at getting into the better unis for CompSci A2 FMaths/Physics?

Okay, at the moment I'm doing my AS levels and my subjects are Maths, English literature, Biology and RS (Philosophy and Ethics). I wanted to pick Physics instead of Biology, but it clashed with RS I (reluctantly) tried to switch RS to Physics a couple weeks back, but it was too late.

Still, I'm hoping to do AS Further Maths - it's extracurricular in my sixth form (and if I can do that, I'm hoping to do the A2, too!). I'm also planning on doing an AS in Physics next year if I do well on my current AS levels, and if I have the option.

But, will I have any chance at getting into the better unis without a full A2 in Physics or Further Maths?

Thanks for any replies
