Anyone do Computer Science @ Birmingham?

I pretty sure I'm gunna firm Birmingham for comp sci. But I'd like some clarity on a few things first. I'm interested to know what the workload and timetable is like. When I attended the open day someone said the course is very intensive and they only got about 30 mins free time in the evening. Is this likely to be true for most students?

One of the specific parts of comp sci I'm interested in is game development. So I was wondering if the course has modules that support that interest? Like mechanics/physics, graphics, etc. (I know the AI's pretty good)

Also would it be unwise for me to put this as my firm when my AS grades were only ABBC and the uni wants AAA?
