Pick 2 out of the three electives in terms of usefulness - ID, Cardiology (with cardio team/CCU), Critical care (MICU). I like all three areas equally. I am interested in doing a residency. Internal medicine is required rotation that I have to take. Can only choose two acute care electives. The cardiology preceptor is great from what I heard. I have no idea about ID and critical care preceptors/sites.
