I'm a happy graduate of Barry's MS in Biomedical Science program. I was in the Track 1: 1 year program. The courses you take there are very similar to the courses that a first year medical student takes like Histology, Gross Anatomy with lab, Biochem, Physiology, Micro, Neuroanatomy, and some 2nd year classes like Pathophysiology, and Pharmacology.
I learned a lot and I hope that it all helps me do a little better in medical school. It certainly helped me get into medical school. Before completing the program, I had 2 interviews, 2 waitlists and 0 acceptances. After completing the program I had 8 interviews with 3 acceptances and 5 waitlists which I withdrew from and I'm going to one of my original top choices. This program helped me a lot to improve my application, as well as others who were in my class.
Some people in my class were non-traditional students that applied to medical school multiple times (one guy 3 times) and were accepted because of they did well in the program. The guy who applied 3 times before got in the 4th time and just finished his first year at Ohio State. Barry's program also promotes some stat that they have 90% accepted to medical school after completing the program. I doubt that its that high, and it takes into account that many of them eventually go the Osteopathic route, but if you do really well in the program, it will greatly improve your application to any medical school.
PM if you have any questions about the program.
