SDN Members don't see this ad. (About Ads) My school has free sub to Exam Master online. There are about 8000 questions covering step II topics. Wanted to know if anyone has found this useful? I'm planning on B&W and USMLE world for the real studying in Febuary, but am looking for a primer to occupy my time. So basically are these questions a good primer? I know I should be sleeping, it is 4th year, but I can't help it, I'm bored already. Thanks!
