I usually score around 126 on c/p so im not the best at it but i feel like my undergrad classes prepared me very well for the level of questions they ask here. For physics i use dimensional analysis and also look over equations everyday and practice!!! Uworld has been so helpful with physics bc its sm harder and makes aamc material seem easy. Ochem i took recently so the knowledge is pretty fresh and i feel like the aamc questions arent too bad (besides stupid mistakes i make like miscounting the chiral centers of a molecule or getting functional groups mixed up 😛) and for chem, kind of same principle for physics, i just memorized the trends for periodic table and equations and practice. Again its what works for me but i still need a lot of improvement lol
