I agree with Lauren. At GCSE, you could pretty much wing it without understanding the subject if you had a good memory. At A-level it is a lot more theory based (at least for the subjects I studied). I remember really struggling with Chemistry and Biology at GCSE but rather than trying to understand it, I just accepted it and remebered it. I ended up getting an "A" in both at GCSE.

A-level is more conceptual. You learn an idea and have to apply it to different situations. At GCSE you were almost given the method (especially in Maths) and just had to number punch in your calculator.
