I'm starting my 4th year soon an was wondering about letters of reccs. I'm applying to internal med. I have 1 letter from the GI doc I rotated with, 1 from gen internal med doc I've known since first year, and need one more letter. I will not be able to do my sub-I before I get submit my application, so I'll have to do another internal med rotation. Would it be OK to do an elective rotation in GI since that is what most I'm interested in and get a letter from another GI doc? Also how important are these letter really?
