Imperial is where you'd wanna go out of that list.
Well aware, both Imperial and Durham are top unis. Never applied to Oxford and Cambridge because, in all honesty, my school's retarded and my predicted grades (required when applying) weren't given till like early jan. Couldn't be bothered to write mock exams to get them that early either, so yeah, stuck with Imperial as my top choice and Durham a close second. Warwick ain't bad though, sure beats most other unis.
I have a couple of mates that are at Warwick actually, positive stuff heard from them. Personally, I technically got the grades for any uni I wanted A A B if I retook the B I could have gone to Oxbridge. I'm just done with school.
