Hello,
An AAD prediction isn't too bad to be honest, the two As will certainly boost up the feasibility of getting into uni. One of my friends was predicted CCD for A2 and managed to get himself an offer of AAB and another for ABB for universities despite his predicted grades. So it really depends what you want to do, you could try and apply for maybe one, or two courses 'over' your predictions and three more which fit them, and at the end of A2 if you have exceeded your predictions by loads, you can always go through adjustment or even clearing, since there are great courses to be found there. (Be warned, clearing is a nightmare to navigate, lol)
Hope this helps!
