Just wanted to put some emphasis on the new sidebar items I've added: MDCalc, MedCalc, Intern Survival Guide, Learning Radiology, and the EKG Library. These are extremely useful items for all med students, interns, and residents. Perhaps even a higher level might even find these useful.
The Intern Survival Guide is from the U. of Michigan and therefore has items on it that are hospital specific. With that being said, I think it's a wonderful site with a plenty of useful information - especially for me as I begin to sweat thinking about July 1st.
