I did particularly well on the surgical subcategory of Step 2, and it's owed to this book. Hands down, it's the best, highest-yield 3rd/4th year review for surgical disease - including epidemiology, symptoms, signs, diagnosis, and management. Awesome for review before the big test; also useful for overview of surgical diseases during your clerkship. One small complaint: it costs lots of dollars for about 100 pages.
