Forget RRPath or skimming FA. What are your weakest areas? Focus on that. Then move on to the "high-yield" forgettables: biochem (becoming medium-yield), microbiology, and pharmacology. Pick out the important tables in FA and make sure they're well and truly memorized. There's also no excuse to miss any biostats questions; it's plug and play with a few equations and basic pattern recognition. From my experience, people often review too much material, particularly lingering over what they're most comfortable with. That's just normal human nature.
I'd use a few days to drill down on your weakest FA sections using USMLERx, repeat missed UWorld questions, take another NBME, and then reassess. The key in the last two weeks is to shore up your weaknesses and drill down hard on the high-yield stuff. It's the curve that kills you in Step 1. Missing an extra few easy questions per block can make huge, huge difference in your score.
Caveat: I didn't get a monster SDN score, but 250+, and I've tutored about a dozen students now.
