You can get to AAA.
Resit a bunch of your modules in A2, work your ass off, and if your chosen degree absolutely requires AAA, I might recommend taking a gap year and applying then. It might be difficult to convince unis you can get AAA from BCC, but if you apply with AAA in hand you're more likely to get in. I'm hazarding a guess that this is medicine? If so, there's not much use in applying to traditional courses in year 13 with those grades, but applying in a gap year could be worth a shot. Alternately, some foundation courses ask for grades around BBB/BBC.
