I'll bite.
The M.S. program is completely new. As in if you apply you're apart of the first LECOM M.S. class. Their post-bacc in the biomedical sciences has been around for a while and I'm sure since you posted about this, you took some time to look into their website. Their curriculum is much like that which you will find in other 1 year prorams as a comprehensive curriculum in the pseudo med school classes, ie. immunology, virology, histology, anatomy etc. Class size is about 60ish or so and you take all your classes apart from the medical students but under the medical school faculty. If you score a 3.3 in the program and above a 23-24 MCAT, you will be guaranteed an interview around the month of February for the class for next year.
The M.S. is a new deal that they had just created which seems as if it's more or less the post-bacc attached with the second year of research which they will grant you a Masters degree upon completion. I'm guessing it's the same deal with the interview and the cons would be spending an extra year, the pros would probably be getting a Masters degree and some background in research which will undoubtedly help you when you apply for residency. The Post-Bacc will only give you a certificate.
That said, 2 of my friends have already gone through LECOM's post bacc program and one should have her interview on Wednesday actually. According to her some of her friends in the class have already gotten a conditional acceptance letter. You can prefer the PBL, IS or lecture based tracks but I guess they decide which track you ultimately get placed into. Tuition is about 12-13K.
Hope this helps.
