This is the third time that I've posted this but I'm happy to repeat it because I regard it as extremely important:
University should be a 'total immersion experience', not just a place of study. Making new friends, learning to live independently and some (possibly rather wild!) socialising are just as important as learning new facts. When I was teaching 6th formers, and giving them advice on FE choices, I always STRONGLY recommended that they shouldn't even consider any university which was within commuting distance from home (or where they could reasonably expected, by their parents, to return home on most weekends). I used a 150-mile radius as a rough rule of thumb.
If you really want to get the best from university (and that means really ENJOYING it!), you should delete UEA from your list.

(PS: I've got nothing against UEA. It's got a world-class reputation in environmental sciences, but I still don't think that it's the right place for you, Molly)
