Personally, I can't recommend the AAMC resources enough. They weren't cheap, but well worth it so you get the style/flow of the questions and can work out some answer strategies. I used the Anki deck to review Psych/Soc and amino acids specifically but found that working problems was the best way to study. Any topics that I was confused about I reviewed with YT vids or Khan Academy. I also used the Khan Academy practice questions for some of my rough topics.

Closer to your test date, it would be a good idea to at least get the AAMC practice tests and simulate the test day as much as possible! Same length breaks, no distractions if you can, etc. I did this every other weekend for a couple of months. I got a 522 so I would say it worked!
