I read blueprints, case files, and FA for obgyn and did questions from UWISE and pretest. overall, i think that case files was the most helpful even though it doesn't cover everything that is in blueprints. I didn't think the Uwise questions were that great but I think its the best question resource for ob. I didn't think the shelf was really difficult and time wasn't really an issue and managed to get an honors grade on the exam.
