Some of the MSTP websites (like Pitt and Chicago, for example) require that you list two or three recomenders to send letters directly. They state that these should be in addition to the AMCAS letters. I have had the same PI for the past three years and he and two other science faculty wrote letters for me. They are all included in AMCAS, so my question is: should I just have those writers upload the same letters they did for AMCAS to the MSTP or are they honestly expecting new material here? Any help would be much appreciated! Thanks.
