So there are quite a few schools around that accept either a committee letter or, if your school doesn't have a committee, individual letters. For example, Yale requires "An evaluation from the applicant's Premedical Advisory Committee, or individual letters from three of the applicant's teachers, two of whom should be in science fields." So does this mean if I submit a committee letter, I don't need 2 science letters? Or do I still need them anyways/it'll look weird if I did not?
