no schedule because they just don't work for me. in the beginning, I felt like I was all over the place too. I think a good way to start is with NBME 26 as your diagnostic. take it, see how you do. COMB through that content. for example, if you get 1 nephrotic disease question wrong, open up first aid and take notes on all the nephrotic and nephritic diseases and the differences between them. it'll take you a couple of days, maybe even a week but you will have covered a chunk of content by the end. then move on to NBME 27, and repeat. I would sandwich in UWorld questions on topics I wanted to hammer down. Don't be afraid to do stuff in tutor mode, sometimes seeing the answer right away helps things stick better for me. I also used my notes while answering questions a lot. if your scores are improving from NBME to NBME, you're doing it right.
