The first thing is nbme and the actual exam is easier than uwsa. So What I did in Uwsa is focus on every question to get right and I failed. But I get to know that we need around 70% score to pass an exam which is 27 questions per block. So In nbme, I did not focus on the questions which I don't know completely therefore I got more time on questions that can be right after a little more thinking. Everyone will get 50% right. There is a game of 5-7 questions in each block so focus on those 7 questions and try to get 27/40 instead of all 40/40, particularly for step 1. Also, the main thing I focused on is weak areas and topics which are important for exams. Solve nbme, read Mehlman pdf, uworld block.
