Some universities may let you in, but most likely not a particularly prestigious one. Also, it's most likely that you'd struggle without having done your 2nd year (A2). Therefore the best advice I can give (although not very helpful and a pain) is that you simply have to do your 2nd year for physics, which may be tricky.
And surely you could carry on at your current college to do that? If not another school would surely allow it. Hope you sort it out, good luck.
It would be unlikely that a good university would offer you a place, if you look on UCAS, you can see that most courses require both Physics and Maths at A Level, so if I were you I would saty back and complete a Physics A Level.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
