I plan on applying to Internal Medicine for the upcoming application season. I've been reading that it's important to do a sub-i in IM to get the experience and a letter, but my school doesn't offer or require it. Should I do an away sub-i? ICU (which is required)? A normal away IM elective that functions as an "audition" rotation, and not a sub-i? I'm kind of at a loss and I've already spent so much time researching with no solid solution I can be confident in.
