Ok quick question about Interfolio and other letter collection services, from what I understand, your professors send 1 letter to Interfolio, and then for some fee, Interfolio will mail out say 20 letters from each professor to your 20 schools? So each professor is only sending 1 letter to Interfolio? Or are they sending 20 letters to Interfolio, and then Interfolio sends them to 20 schools (which doesnt make much sense)? Sorry, just making sure.
