I'm echoing what a lot of my learned colleagues and higher ups said above: OME, Casefiles, Uworld. Case files is pretty great, OME gives me some good additional clinical tie ins and lamens terms, and Uworld is just great for practice, since we are talking about an NBME here. Bury your FA and Pathoma, OP. Or you could burn it, maybe that'd be more cathartic.
This is specific for OB/Gyn, but I actually found going over the specific step 1 material (not including anatomy) to be extremely helpful for the shelf exam. Casefiles, Uworld and the ACOG questions were far more useful though. I realize this is N=1 but my exam was like 75% from the aforementioned materials, 10-15% step 1 material and the rest either material you picked up on the floors or bullsh*t questions.
