P.S Hello from across the pond!
I'm a USA applicant and I apply Computer Science major of Imperial, UCL, KCL, and U Manchester. On the websites of Imperial and UCL they say that the requirement is 5's(equivalent to A*) in 5 AP exams. I got two 4's in AP computer science and AP physics 1. I will take 7 AP(physics 2, physics C electricity and magnetism, physics C mechanism, French, Calculus BC, micro and macro economics) this year, which will be after the application season. My predicted scores for those APs are 5,5,5,5,5,5,4(French). Do those two 4's affect greatly on my chances of getting a conditional offer from IC and UCL? I've emailed UCL and they say those previous scores will not affect my chances, but I'm not sure if that's the same for IC.
You don't major in a subject in the UK - you read it, and pretty much only it.
You get 5 choices, so can afford to aim high with one or two. Good luck.
