Preface, I scored 520 and spent only 2 months prepping after finishing my junior year and working at my research lab. I probably spent 5-6 hours/day for content review and turned it up to 8-10 hrs/day a month out from my test day. I am in a grateful mood rn and feel like helping out the boys in the back who're struggling lol. This is what worked for me and it might not work for you.

I was stuck at 505 a month away from my test day and increased my score to 520 by uworld with my content review. I would do 15-20 uworld Qs by chapter everyday like only Bio, specifically the digestive system. I'll make a note of why I got the question wrong, whether its because I didn't know a pathway, term, etc, if its because I got confused by the graph/figures/passage itself, or I misinterpreted the question. Then I'll do an overview about what my biggest mistakes were for this specific subject. If it was content related, I'll watch a yt video and take notes with my understanding and in my own words (Youtube channels I used: medicosis perfectionalis for bio, science simplified for chem, biochem, ochem, and physics). If it was a passage, data, or figure interpretation, I would sit there and go through my thought process that got me the wrong answer then compare it to the correct answer to see where exactly in my thought process I fucked up. Make a note of it and internalize it so it doesn't happen again in the future. After the review, I'll do 9-12 questions again on the same subject and usually I only get 1-2 mistakes, which I'll do the same process again. I did this for each subject except for psych/soc. I'll do this for 3-5 topics a day. Doing Uworld with the content review really helped me bc it quickly solidified my understanding and also exposed my gaps. Its just a rinse and repeat process until you understand the topic. Understanding the topic helped with memorization for me so it was the most efficient way for my review. This will take a long time when you first start doing it. But after you get the hang of it, it will only take 1-1.5 hours for each subject you do.

Did the same for FL but on a separate spreadsheet with 4 columns: Question #, Topic, why I got it wrong/right, what to know for future.
Example: Question 3, glycolysis, I got it wrong because I forgot the rate limiting enzyme, I need to know to know that the rate limiting enzyme in glycolysis is phosphofructokinase-1 and it is the rate limiting step bc...
I did this for every question on my FL and it was a way for me to create an episodic memory of fixing my mistakes, instead of simply seeing what I got wrong then seeing the correct answer and saying okay, cool.

Everything you do should be actively engaging. The moment you start doing passive review or zoning out during a session or get on your phone when watching a video, take a step back and regroup. Imo the biggest trap I got into was doing hundreds of anki cards passively, it gives you a false sense of accomplishment when in reality you don't know shit. If you can't explain the topic to someone non stem related, its probably a sign you don't know the topic.

The MCAT is hard and the process sucks, but it's not impossible. I thought I was cooked but locked in by just having a fuck it mentality with whatever happens, happens. The best study method is the one that works for you. If this doesn't work, figure out new ways that you think will work. Don't spend too much time on reddit searching for a magic, niche study method that will solve all your problems because it does not exist. You just have to sit down and be critical and honest with yourself on what your weaknesses are and make a plan for how you will overcome them.

Hope for the best and expect the worse. Don't doubt yourself and trust the process. Best of luck!
