Computer Science at top universities with resits

Hi everyone,
Are there any cases of people getting into universities such as Oxbridge, Imperial, UCL, or Warwick for Computer Science with A-Level resits? Just wanted to make sure my aspirations aren't totally hopeless - drop a comment if this applies to you, thanks.

Not 100% sure but bear in mind computer science, especially at Oxbridge and Imperial is outrageously competitive, at Oxford I know for sure it is the single most competitive course. The fact that you had to resit the A level could possibly weigh you down, but remember your application will be considered holistically, as in, they will look at everything to determine whether you receive an offer. Do you have any offers to study compsci this year?

I had a contextual offer of A*AB from UCL, which I unfortunately missed as I got A*ABB with the A* in the wrong subject. I'm planning on retaking 2 or even 3 subjects and I know for sure I can achieve all A*s but I'm aware this puts me at a massive disadvantage even though I have extenuating circumstances... I just have no idea if it's even worth reapplying to top universities.

Any other offers?

Yeah, but none that I'm in a position to accept. I had an offer from Warwick for A*A*A and one from Southampton for A*AA. UCL was my firm, so the other two were pointless as the requirements were higher.

Might need to resit next year then, you mind if I ask specifically what subjects you achieved each grades in
