Because 'skins' was set there. Is this a weird reason to want to go to a university?
Yes. And quite apart from anything else, having grown up in Bristol, I can assure you that the city isn't quite as Skins made it out to be. It's still a great city, but I don't think anyone spent their sixth form years as the characters of Skins did.
I went to uni in Bristol. It's not really like Skins though you may recognise some of the locations. I used to live next to the weird white tower thing (some kind of mobile phone mast maybe?) that was in the intro.
I have a offer from Oxford so I will probably go there, Bristol is a good alternative though. and a very interesting city, and, no offence, but, I don't believe people that say it isn't like skins. Must have been a reason to set it there.
