AP summer prep and tips

So I took 4 APs this year as a junior, calc ab, apush, chem, and physics 1, and I am totally relieved they’re all over and hoping i got 4s or above on all. I actually thought they were way easier than what I was expecting, but still hard. Anyways, the anticipation for scores in July has been killing me and I’ve just been thinking about them ALL THE TIME. So I started thinking about next year!!! Awesome! And i was thinking that if I had done more preparation this year, the whole year would’ve been so much less stressful and I actually would’ve understood everything. So any tips for classes next year?? good review books, summer prep, practice advice, etc. As of now, as a senior in the fall, I’m enrolled in 6 Aps:
Physics C
Clac BC
Stats
Psych
English Lang&Comp
French language

Any advice would be great, thank you!
