Hey, I was just wanting to get everyone's opinion on this. At the beginning of the summer I had 4 letters of rec submitted to my premedical committee, and I believe that they have already finished writing the composite letter. During the summer, I was in a research program at Hopkins. I would like to have my mentor write me a letter, because I feel that it would be somewhat stronger than some of the others that I have gotten. How should I go about using it? Should I submit it as a suppliment to my application or what? Should I just not worry about it considering I already have plenty of recs?
