I've already put the entry requirements for the school I'm going to, but at my current school there are no "official" requirements. Obviously you need C's in Maths & English, and they prefer you to get A's & A*'s in your A-Level subjects. If you get a B they try and persuade you to do a different subject. If you want to do a Science A-Level, you can get away with B's in Triple Science, but not in Double Science. And for Psycology you need B's in Maths, English & Science.
Have you been tested?
