I start my surgery rotation soon and was wondering what's the best approach to rocking the Shelf? At the moment, I'm thinking deVirgilio, uworld, OME, Pestana Audio, and the Pestana PDF (Surgery review). How does that seem? I'm also a little confused on Pestana. I hear people talking about some "little green book" or something? Is that something different that I should be looking into? All I have is the 79 page outline in PDF form.
