Would this be enough for Oxford/Cambridge?

I have been looking at possible universities go study computer science at and Oxford or Cambridge seem to be the best places to go, after trying to pick one I went for Oxford as it seems to be a better place to study and also has slightly lower entry requirements. However im not sure if my grades will be good enough to get in, any comments on how likely i am to get in?

GCSE: A* x2, Ax5, Bx2

A-level: A* (A2 maths),A (AS physics), A (AS computing),
A (AS geography, dropping this next year).

next year i will also be doing further maths but havent yet sat any modules.

Thanks

Maths:
c1:98
c2:89
s1:80
C3:98
c4:100
s2:88

physics total: 285 (max 300)
Computing total: 170 (max 200)
geography total: 167 (max 200)

Well your GCSEs may not be best for Oxford since AFAIK Oxford place a far greater emphasis on GCSEs than Cambridge seemingly does. Post up your AS module marks and we'll see if we can judge whether Cambridge would be a safer option than Oxford. The AS results are encouraging.

Oxford's main shortlisting criterion for interview is the admissions test, and not GCSEs. Though, as you say, Cambridge ask for module marks which Oxford do not.
