It says on AACPM that the two schools I am applying to (TUSPM and NYCPM) use Interfolio for LOR's. My premed adviser has all of my LOR's as well as a committee letter. I'm kind of confused how Interfolio works and it looks like I have to pay for it? Does anyone know how this works? Can I just have the letters sent directly to the schools? Also, should I send them while I send everything else (transcript and application) or am I allowed to send it later? It says I can also bring it to the interview but that seems a bit late. Thanks.
