Help with Changing my Uni Choices!

Hi,
I have already submitted my UCAS application to study Computer Science w/ Year in Industry with the choices: Surrey (AAA-AAB), Nottingham (ABB), Kent (ABB), Royal Holloway (ABB), City (BBB) with my predicted grades being ABB.

I already have an offer from City and an interview with Kent. I wanted some advice if I should change Surrey to Nottingham Trent so I can pick between them or City for my insurance choice. As I'm not thinking of picking Surrey as my firm but at the time wanted one risky choice, I will pick a uni with ABB for my firm as that's more realistic. I have until Tuesday or when Surrey respond to change.

So any opinion on what to do? I know Nottingham Trent isn't the best for Computer Science but its better to have an opinion than to go into clearing/getting a rejection from Surrey and waste a uni choice right? Anyone taken the course at Nottingham Trent?
