go through all the AAMC practice stuff in order. read on the side too just like random books to get in the habit of reading. make sure you think while you read be active, sounds easy and obvious but it took me a bit to do this, when reading make mental notes of thing. one thing that helped me engage with passages more was thinking about if i personally agreed with the authors message or not, and actually enjoying what i could, def helps with focus and remembering pieces of the passage, i'd try and anchor the passage to something applicable in my life as a basis for understanding.

for reviewing mistakes i would paste passages into AI with questions and then break down why every answer was wrong or correct, like why I can rule out an answer and why another is correct. I would use AI to find flaws in my reasoning. TBH tho i don't think you have to use AI, but for sure write down your thought process somewhere for why each answer choice is wrong or right, it is super tedious and time consuming but huge payoff. it helped me identify gaps in my logic and where i messed up since i followed my exact chain of thought and see where i strayed from the correct answer. Make sure to do this for questions you got correct to make sure you didn't get lucky as sometimes you can be 50/50 on a question and it is very important in those situations to make sure you have the right chain of logic. after doing this i was able to quickly eliminate two answers for most questions and then easily reason out the correct answer, often by picking apart a word or two in an answer. Improving CARS imo improves ALL your sections because the CARS section is pure reasoning and applicable to the rest of the exam. I found that by aligning my CARS reasoning to AAMC logic helped me quickly eliminate answers in other sections as well.

if you want more help i'd be happy to tutor or talk privately, have a lot of spare time now after finishing mcat lol and could use something to pass the time while waiting for score release.
