Is there a chance for me at getting into Oxbridge University with these results?

It's clear that you are extremely academically gifted, but that doesn't necessarily guarantee you a place at Oxford or Cambridge. For example, one of my friends took Maths, Further Maths, Biology, and Physics at A-Level, received an A* in all four of them and an A in his AS level Chemistry, and didn't even get an interview at Oxford. However, another one of my friends got A*s in Maths and Further Maths, and A in Physics (all A-level) but just an E at AS Level History, and is currently studying Mathematics at Oxford. References and your personal statement are deceptively important in your application, as well as your grades. So make sure you focus on these too. However, i'm sure you will do very well in your A-levels and hopefully attend Oxford or Cambridge. Good luck! :
