Thank you guys!
I'm very happy as well to get my 270+ and I'm gonna share a little about my experience.
I'm an AMG at one of the top US medical schools. My school has a very competitive and rigorous third year training so in order to get honors, we have to study very very hard (do not miss 3rd year at all).
My step 1 score was 250+
I think my biggest help was my clerkship in 3rd year. I learned a lot from my 3rd year as well as my 4th year rotations (sub-I in crit care, cards, and GI before taking my step 2 CK). Before every shelf, I would do all the related Uworld questions and read either case file, blueprints, step up to medicine, or pastanas (or multiple sources) for each subject. I usually score in the 80's-90's in every shelf, and I believe that helped me a lot.
I had about 3 and a half weeks of dedicated study time for my step 2CK. I read first aid once to get an overview. This took me about 3-4 days, which in retrospect probably wasn't the smartest thing to start with first since first aid was very very detailed and there was no way I was gonna remember every detail. But I do suggest reading a broad resource before doing questions to refresh your mind on all the topics that is a little bit rusty, I would recommend starting with Master the Boards first, which was a very easy read and gave me a good overview.
After reading First Aid, I started to tackle Uworld (this would be my second pass already as I have finished all the questions once during my 3rd year). As I went through the questions, I would take detailed notes in my notebooks (insert picture on the bottom). I did about 6 blocks a day, which took me about a week and a half to finish all the questions.
Starting third week after finishing First Aid and Uworld, I read Master the Boards. This was an easy read and took me about two days. Then I started doing NBME questions. I did all the NBME's available. I ranged from high 260's to mid 270's. I don't remember all the numbers, but I think I got 274 on NBME 6 and 272 on NBME4. I also did UWSA, which I got the lowest score of 250.
At the end of my third week, after finishing all the NBME and UWorld questions once, I went back and did the wrong questions in UWorld.
About 3 days before the test, I read USMLE step 2 secrets (took me 1 day) and the notes (5 note books) I took from UWorld questions with their charts and explanations, then I took the test!
I definitely feel like I studied more than a lot of my classmates (most use 2 weeks and use less resources), but I think its worth it!
Hope it helped!
