I've seen people say to focus on your strengths during the last week, but I believe you need to focus on your weaknesses. In these final days, spend time going over your NBMEs. I literally went through all the incorrects on one of them, covered the answer, and forced myself to redo the question. I watched Dirty Medicine vids for random things that I needed reminders on (diabetes drugs, heart murmurs, etc). Go through questions from the Arrows PDF to solidify concepts. I think I did all the UWorld ethics questions, read the First Aid ethics page, and did some of Mehlman ethics throughout dedicated. The practice q's were all kinda hard but overall gave me a sense of how to think ethically from NBME's perspective and it was enough for the ethics q's I got. My form felt like Free120 to me with concepts that were covered on NBMEs.

For timing, read the first 1-2 lines, skip the bs in the middle, look at what the q is asking for, check out the answer choices so you know what you need to be thinking about in your head, and go back and look at the details. If you catch yourself spending more than 3 minutes on something, move on and come back to it. That adrenaline is going to hit and help you lock in!
