Read the wrong answers. Read every word of uworld and understand it forward and back. Put yourself through hell for 4 months rather than 40 years. If you're interested in doing FM or psych or PM&R, who gives a **** about step 1. But if you have any desire to do something competitive, or just keep your options open, do what I just said. You may be incredulous when people tell you that step1 is important. You might think that surely programs will look at the "whole applicant" not just some board score. But, programs have cutoffs. You won't even get an interview at many programs in several specialties without a 240, for example. What percentile does a 240 put you in, anyways? Like top 30% top 25%? It's a really good score, but like I said, programs in the most competitive specialties do have those cutoffs and they can get away with it because there are enough students with these scores to fill their rosters year in and year out. And you might tell yourself, I'm happy with a 240 because that's a really good score, and what difference does a 249 or 250 make when I already scored above 240? It makes a difference, and you should fight for every point.
You need to study hard, painfully hard for step 1.
