What uni? I am going to be doing it at Nottingham! Specifically because they claim to have a 80-90% pass rate vs other unis with an average of 60%. Not paying 9k to to fail lol, even though I have offers from some better ones, it's all just really getting in to year 1!
Also what's your background? GCSEs and a-levels/btech? You have to be pretty sure of yourself. As an example I got mainly As at GCSE, Bs at AS and need BBB for A2, probably making me a stronger candidate than someone who did bad at gcse, didn't do A-levels and hasn't experienced the stress of exams. But if you work hard and at unis which are most likely to pass then you shouldn't be fearful! Trust me A2 is another step up( I got Ds and am retaking it) and so doing Physics and maths full a-level will be tough! But I can't wait!
