When I interviewed at Barry, my student guide told me he got a 15 on his MCAT. He was a PM3 and the class officer. So obviously, some schools will take your friend. Considering the sad state fo affairs facing the applicant pool, I would be willing to wager that some schools would indeed take him. Some schools are seriously in need of money and thus would be willing to take a chance on a lower scoring student. This is also why the schools are beginning to take other admissions tests (GRE, PCAT, etc). But if he got a 15 on the MCAT, personally I would rethink my career prospects. That doesn't bode well for your future, especially considering the average MCAT is 24. And its been shown that you improve only about 4 points on your subsequent MCATs. See the MCAT trends published every year for details.
Anyone can take the helm in calm seas. It takes a real leader to do it in a storm.
