Thanks for the responses.
I've looked into detail at the geography courses, specifically at Sussex and Queen Mary as these are the places I would most like to go. The reason for not doing Geography at Loughborough is solely for the reason that if I want to do a whole new course, I may as well do it somewhere else because Loughborough isn't an especially great place to be honest. The uni is nice, the town isn't though. My housemates and friends are all on placement next year so they won't be here, I may as well start anew.
I am considering what you said about Edinburgh though, to be honest I wouldn't really like to go to university in Scotland anyway, I just really liked the course at Edinburgh. Though looking at it, with student finance only being able to pay for 2 years towards my degree, and with the course at Edinburgh at 4 years I don't think I could afford it anyway, and I only got BBB.
By dropping out, I'll lose about £10,000 I think. Which sounds like an awful lot I know, though it'll be worth it once I'm doing a course that I have a genuine interest in.
I've spoken to my mum about it (standard) and she told me that she'll support me no matter what I choose to decide. I think I've already decided. The only thing that worries me is what to do if I don't get any offers from the university and I've already dropped out? That's why I'd like to stay in the meantime, though if that means paying my next half of the tuition fees, I doubt I'd stay.
