honestly all u can do is to just push forward. when I took A's last year I thought I messed up one of my h2 lit papers and I felt like absolute shit, only to end up with a grade I'm happy with

but at that point in time all I could do was push on tbh, bc u never know the outcome of things. and DON'T GIVE UP please never ever give up when you don't know how things will turn out, esp when it's smth as uncertain as A's. continue to revise and rest if u need, and try not to look back at the previous papers after they're done. if there's anything A's taught me, it was to just push forward when I don't know the outcome, so might as well try my best given whatever circumstances I'm in
