I think that isn't the best idea... it's the random things in medicine like factor deficiencies and such that come up for the surgery shelf, stuff you wouldn't really get from a brief overview of Case Files Medicine.
I got a 99 and the highest grade on the surgery shelf at my school in quite a long time apparently. I was obviously very happy with my score, but I thought it was a very difficult exam, much more so than the medicine shelf. In fact, I was down to the wire, and finished bubbling in an answer just as time was called. There were quite a lot of questions that I spent 5-10 minutes thinking about and reasoning out in full detail, and a lot of them I could narrow down to 2 answer choices.
I think I'm the only person who didn't read "Recall" fully, I just glanced at relevant sections for relevant surgeries and used it as a reference to prepare for our departmental exams. Someone sent me a copy of Pestana's lectures in audio format (apparently converted from video) and I listened to those pretty thoroughly. In fact, I can do a pretty good Pestana impression now. I love the way he says 'trauma'. Anyway, he lectures directly from his vignettes, but elucidates a little bit more and obviously is more dramatic when emphasizing important points. Went through all of Kaplan (both sections -- vignettes + the other half). Did all of pretest (wasn't that great -- do this book if you are bored). Did all of Kaplan questions (pretty good). Did all of A&L (lots of wrong answers in this book, lost of extraneous minute crap that isn't even tested -- skip this book). Looked at Lawrence for important chapters (acute abdomen, trauma, etc.). Know trauma well. Lots of random medicine stuff. Know when and when not to take someone to the OR and perioperative complications / fevers / etc. I was initially afraid of relying on Pestana so much, but in the end, it paid off. World questions were good, but started to sound the same after a while -- do them, though.
