Agreed. Besides the fact that it probably won't look that great on your UCAS form (Unless you're applying for sociology (Y) ), it'll probably be boring as hell.
As for the whole OxBridge thing... In my experience, people who go there are a different breed. I went to pretty posh grammar school and a fair few of my friends went to Oxford/Cambridge. There's a couple who are doing Classics (Latin and Greek), and they love it. They're ultra-competitive and work all the time (In fact, one of them is helping to compile a Greek dictionary in his spare time (Y) ). Even during the holidays, they've got loads to do. Now I'm sure they enjoy it, but I'm very glad that I didn't apply there! Another friend is at Cambridge and she hates it. Full of posh people who take the piss because she watches Neighbours... So, I would say that seeing as you don't seem very sure at this point, you would probably be better off going elsewhere. You'll have a better time (And you'll probably have some time to go riding!), and if you go somewhere fairly decent, then it won't be too hard to get a job (Y)
