I think something which most people will agree with is that, regardless of your gcse grades, once the work starts to become tougher, which it does at AS and A2, you almost automatically start to get your act together. Why? Well because you begin to realise that it’s now about a university place, something which you weren't thinking about as much at gcse. The other thing is that at AS and A2, you are studying your most enjoyable subjects (hopefully) so life does not seem like a drag. Hopefully you will find that because you're enjoying your subjects, you will perform well all round!
