In terms of med schools admission...I would wager than PCOM is more competitive than LECOM.
Case in point: I received a med school interview invitation from LECOM and not PCOM🙄 Although...I was surprised I got the interview in the first place.
I don't know much about LECOM's post-bacc program. I do know someone who did PCOM's post-bacc program, did very well and received multiple dental school acceptances the following year.
