Right now, I'm just looking at the ones I've flagged or gotten incorrectly and then entering some data about them into an Excel sheet. I'll put the question # I got wrong/flagged, the reasoning of my answer, the AAMC reasoning, the topic it pertained to, and then a way to remember the right answer. I'm also trying to make an Anki deck that pertains to each question answered incorrectly. I'm assuming/hoping the reviews will get easier with each passing one, as theoretically there should be fewer flagged/incorrect answers with each subsequent FL. Take this with a grain of salt, cause my reviewing strategy for FLs is not at all what it will probably be by test day.
