I failed Step II the first time around after studying for 7 months when I was off from med school (volunteering 30 hrs/wk in my field). I filled my First Aid book with notes and continuously took Kaplan tests on-line. I overdid it. So, second time around, I gave myself about 6 weeks, 3 weeks during ICU and 3 during radiology. I used Crush Step 2 and USMLEworld.com (I think) for questions. I liked both better: Crush is more paragraphs, less lists. I liked the explanations better in USMLE world than in Kaplan. I did much better than I did even on Step I. It was mainly a change in attitude; instead of thinking during practice tests that I would learn by reviewing the answers, I pretended each practice was the real thing. I took time between finishing the test and going over the answers instead of going straight from one to the other. I also took breaks during both the practice and the real tests. Every 10 questions, I closed my eyes and took some deep breaths...so I was calmer, too. See how you do best when taking practice tests and transfer that to your real test experience.
