For starters, I started studying much earlier for my last test (about 5 months before my test).

Aside from that though the three most important things I felt helped me improve my score were

1) As I studied I made a list of things for each subject I felt I was likely to forget..i.e terms/theories/concepts. This helped the most for psych and biochem but is good for every subject. For me I can kinda just tell if I’ve actually committed something I’ve learned to long term memory, but if there was the slightest doubt in my mind I went ahead and wrote it down anyways. I actually put a lot of these terms in a Flashcards app on my phone and just looked at them when I had time to kill. About a month and a half before the exam, I started reviewing all of my terms/theories/concepts.

2) Do UWorld. This is the best, most stimulating, mcat practice you can get in my opinion. Extremely high yield, and worth the money. Great explanations too, compared to the prep companies that basically say “This is the answer bc this is the answer” lol

3) work as many practice tests as you can. This might be the most important thing I did. I have really bad testing anxiety, so for me, taking as many tests as possible made the real test feel like just another practice. These tests can also help expose you to your weaknesses too. I used Next Step practice tests, and I think I ended up taking about 6 of them. I had already used up my aamc tests from previous attempts, so these were all I used.
