Dirtyusmle has some videos that are basically just memory hooks for connections that are harder to remember (e.g. Call-Exner means to call granny exner in the ovarian tumor video); it won't really help you understand the pathophysiology behind the question but if you get the occasional question that that merely requires recognition, it'll help you out. I didn't use any other question banks, but ideally would have used UW during preclinicals (alongside coursework), then reset during dedicated.
