I got A’s in Maths and Physics, B’s in Further Maths and D&Tystems and Controls, a D in General Studies (not that i took it seriously), and I taught myself the AS Electronics - I ended up receiving an A in that, as well as being entered into the Electronics module in Physics, in which I also received an A.

As I'm an international student, I wasn't required to have an interview at UCL. If you mean Cambridge interview, well it went well and I got (and subsequently met) an offer though I didn't go for financial reasons (fees for international students = 17,000 per annum for engg ).
