What's this about PCOM's weird LOR requirement? As far as I can tell, they are pretty much on par with the other schools' requirements...from their website, "Applicants are required to submit a letter of recommendation from the premedical committee or premedical advisor of the undergraduate college that grants or will grant a bachelor's degree, regardless of your academic major, course of study or graduation. If that is not possible, a letter from your academic advisor or Dean of the same institution may substitute. Another letter of recommendation, preferably from an osteopathic physician, is suggested but is not required."
I think all the schools I applied to (with the exception of MSU) state very similar requests. I just got one from my academic advisor (even though I'm an old fart and graduated in '01 - lol).
