Worried for A2... help

I take maths, chem, phys, fm
my predicted for each rn (obv all exams havent been taken yet but from how ive been performing so far + from my mocks):
- maths: 120/125
- chem: 109/130
- phys: 117/130
- fm: 108/125 (def need to retake, i messed up p1 so bad)

idk im so worried about chem & phys because i feel like the grade thresholds will be super high this year... i really need 4A*

can someone who achieved A* in these subjects please tell me what they got in AS & the PUM? if you did worse in AS than you did in A2, what happened, how did you improve? how was A2 better for you?
