1 shot, studied 2.5 months - scored 90
But in my opinion, if someone tells you they studied 2 months, 6 months, etc... It really doesn't matter. The distribution of study time needed varies greatly between individuals. DO WHAT WORKS FOR YOU!
I used the typical recipe for the CBSE - UWorld (most significant source), Sketchy micro and pharm, pathoma, and First Aid (least useful). I truly believe first aid should not be read like a text book but more as a control find source. Its to time consuming too read page by page and honestly doesn't really teach much at all. If you have a photographic memory, then by all means read it. Otherwise, use it as you go when you want a few extra details. For instance, I used pathoma for my path, which eliminates so much of First Aid. I only used first Aid to supplement my embryology (w/ UWorld) and physiology (w/ UWorld and some school notes). No need to read drugs or micro from First Aid - use sketchy (waaaaay better). Just try to be as efficient and smart with your time as possible and utilize first aid correctly - otherwise its a real time cruncher with not enough solid yield.
So, I think UWorld + Sketchy + Pathoma is all you need to do very well, and just use First Aid for areas where these are lacking (physio, embryo, anatomy, psychology (probably the best source for that), and stats - though UWorld really does cover these topics even better than First Aid)
And take NBMEs - know where you are at, and do some to improve those deficiencies but don't get to hung up on it either. You don't know whats gonna be on that exam, so never throw all your eggs in one or a few baskets. Just try to give a little more time to the topics you need a little sprucing up on and then once you've improved balance the time again and cover as much high yield ground as possible.
If anyone has any question, please message me. I believe everyone here is capable of scoring very high with the right strategy and work ethic.
