I had a Word doc Notebook split into the PS/VB/BS section. For each question I got wrong (and even some I got right, if I took too long on them or guessed or whatever), I would write the general idea behind why I got that question wrong (Content, math error, made it more difficult...etc). Then, I would expand on that with maybe 5 sentences discussing what I was thinking in the moment and how I should be thinking in a different way to get the right answer. For me, writing things down like this really embeds in my mind. I plan on re-reading my notes on this before taking my next AAMC. For any incorrect questions due to content errors, I highlighted that topic, and re-read/focused on passages in TBR to supplement.
This took me almost all day yesterday to do the PS section. Granted, it was my first test that I was checking, and I should have gotten more right...regardless, I think taking more time to check is a learning process and can be more beneficial than just breezing through it and focusing on more passage work.
Hope that helps!
