I cannot even remember everything about what I did exactly. But it was pretty extreme. Goes a little something like this:
I remember throughout second year of med school I read through Goljan's Pathology (do you kids still use this these days?) book along with my path class. I mostly focused on Goljan and just skimmed through my lecture notes right before the tests. I would read Goljan chapter 5x prior to each exam in class. I also listened to all of the GOljan bootleg lectures 3x prior to each exam.
Then around this time of the year I started reading Goljan again from page 1 so I could read through it in it's entirety again prior to the end of M2 year. Then I read half of it again during my ~5 week study period.
I also read First Aid 3x during my dedicated Step 1 study period. I didn't read it much prior while going through M2 year. I barely touched it until I had my 5 weeks off for pure Step 1 study.
Also during that 5 week study jam session I started USMLE WORLD and ran through the whole qbank once, all timed, random, blocks of 48 questions. Spent most of my time reading through ALL of the explanations, both right and wrong questions.
I studied 14-16 hours a day, every day, during my dedicated 5 week study period after M2 year. After that experience, a part of me died inside. I will never be the same. But I did score 250 on USMLE Step 1.
Good luck.
