I'm a 4th year applying in IM with a whole lot of time on my hands coming up. I took the past year off for research, and I'll be spending much of 4th year on research projects as well. Does anyone have a recommendation on a good IM book I could read in preparation for residency, so I don't lose all my knowledge? I feel like I forgot a lot during the year away and don't want that to happen again. Thanks!
