Yeh there's a few which are really competitive; Oxbridge, York, Warwick, Bristol Bath, Notts
But there's loads which are equally as good and slightly less competitive, but still require decent grades. I'm predicted AAA and I was accepted by Reading, Birmingham, Liverpool, Loughborough, Lancaster and Sheffield. I did consider some of the more pretentious ones, but after comparing pros and cons I decided these were the best for me to apply to. Although I'm predicted AAA, these are in Psychology, Sociology and Media Studies, and my GCSE grades are poor (C in maths, DD in science) so I prob wouldn't have got into Oxbridge, York, Warwick etc. I applied to the ones who wanted AAB, with minimum C in maths as I thought this would be a bit less stats heavy. I think I'll go 2 Reading; it has an outstanding reputation and is one of the few to have 24 out of 24 and maximum 5* in those 2 test things. If you haven't got really sciencey subjects I'd probably not bother applying 2 any of the few mentioned at the top, but you might have a better time at one of the less snooty ones.
Anyway good luck mate
