At the risk of sounding like I am promoting/encouraging you to buy yet another text source for medical school, I present a handbook created by two WashU medical students to help aid their peers through the complexities of the American medical system. In the interest of full disclosure, I do not know the authors of this book, nor am I promoting its sales. I'm posting this link as a resource to those medical students with a particular interest in the topic (or others who crave more to read after Big Robbins, haha).
