Don't listen to super simplified answers that'll tell you "YouTube, Anki, etc". You seriously have to fill in the gaps of content that was years ago. Youtube will send you down a rabbit hole (most videos are trash, some are good), and there are so many Anki decks, you have to see what works for you. It can literally takes months. The most important advice I can give you is to figure out how you learn and to basically give yourself time to really memorize all the content. Memorizing is only PART of the battle. The MCAT is comprehension, it's not memory (maybe some discreet questions are memory but that's only 15 Q's out of 59). You have to be able to take what they ask you and think steps ahead (or backwards) and read between the lines, which is different from undergrad and which is also why people don't get good enough scores. Also, do not reserve the last month before your test for AAMC. Have everything done at least a month before you take the test so that all you're doing is review, review, review. I see that advice being given out and that's horrible. You may have habits to undo and logic to understand. I hate UWORLD Cars, it's so different from AAMC (you may disagree, but you have to give yourself time to know this). A month out before your test, you want to be scoring at least 5-10 points above your goal score. This will set you up for success. If you have any questions, send me a DM. I can tell you so much more, and really im in a rush before work.
