Heyy, I come from a low income background so earning potential means a lot to me, due to mitigating circumstances I ended up with A*BB and even after attempting to clear into a different course I was unsuccessful but I do have a place a Qmul which is very good but I can’t help but feel I can do better and have a better future if I just retake my two BB grades, someone please help me what did I do.

I’m in year 13 and I applied for law at KCL LSE QMUL and Cambridge, I got rejected from all except QMUL, which I really don’t want to attend, I know it’s because I got 21 on my LNAT with 2 A* 1 A predicted.
If in Alevels I manage to achieve that or higher, of if I take a gap year and reapply, will I have a better chance at uni with achieved grades rather than predicted?

Also what does one do in a gap year? I’m not rich enough to travel the world or anything extreme should I just grind work exp?
