Computer Science subject requirements.

I'm going into my second year of college and im doing maths, physics and chemistry. I dropped computing after getting an AS in it. I've decided to apply for computer science at Bath, I know it sounds crazy since I dropped computing. However at the time of picking what to drop, dropping computing meant I could still apply for most courses and at this time I wasn't sure what I wanted to do at Uni. Now I'm worried that Uni's will see that I dropped computing and won't want me on their course, even if I get the 3 A's that Bath want. Do you think they will mind if I dropped computing, to the point that they won't accept me? Or will they be happy meeting the requirement and just see the AS as a bonus? Thanks in advance.
