This thread wouldn't be complete without me wowing you with the amazingness of biology. It's brilliant! Such an incredibly interesting subject and something you can always relate to. Biology is the most immediately accessible of the sciences because you look out of a window and right infront of you, without any analysis needed, it's right there!
In terms of job prospects I think it's a bit of an apples and oranges with regards to computer science. Both are decent an nobody will hold it against you. If anything, study what you find most interesting, because I guarantee that most people do not work in the sector they pick for their undergraduate degree. I did biology for my undergraduate and I'm not considering a career in science - I don't regret it in the slightest.
For the record, I know people who studied biology that are continuing in the field (phd), lawyers, music journalists, work for the BBC, are teachers, work in pharma-companies and others on various grad schemes. Really not shabby, please do not worry about the job prospect aspect of it because it's not an issue.
Also, study biology at Bristol - the main thrust is on evolution which is undoubtedly the backbone of the whole subject. It's a fantastic university (they are building a new biology department right now). Hell study computer science at Bristol. Amazing city and after 7 years I'm not bored of it.
I hope that helps
