SDN Members don't see this ad. (About Ads) Hello Everyone, I've been on here a few times...mostly silent observer - but have had some great help as well! Just wanted to say thanks and let people know what I used to study: I have not started residency, so was doing this exam while waiting to start in June... First Aid USMLE Step 3 - CCS cases in the back were enough USMLE Q book avg. around 70% (whole book) USMLE World Q Bank avg. around 52% (completed all but a few hundred q's) Read some of my notes from Step 2 Kaplan...just things that were unclear Scored 87/211 not great but happy it's over!!
