Hi guys. Just a quick question. My Principal(med school) has uploaded an LoR on Oasis thru the ECFMG Web Portal. I didn't ask him and I'm expecting my MPSE to be uploaded soon. So my question is what exactly does that LoR count as? Is it a "Dean's" letter? I doubt cause I'm expecting that to be uploaded in a day or two. Or is an LOR? I'm sure its just a generic letter. But still what is it's purpose?
