Your problem is that you have an unusual grade set.
Most top Unis for Law want AAA, and they mean AAA, not one good grade and 3 weaker ones.
Law at top Unis by definition will not need to be in Clearing - they are competitive, will attract top applicants, and they will not need to use Clearing to fill places. You can either apply now to mid-range Unis - those that might accept ABB for example - or you can work your socks off this year to get far better than BCC, and then apply to appropriate Unis in a gap year.
