I'm a P2 at Wayne State. Historically, the failure rate here is very high. We started with 93. We only had 1 drop out P1 year. P2 year 1st semester, 2 dropped out completely, but another 12 failed and are being held back a year. So we lost almost 20 % of our class the first 3 semesters. We go by the 7 week module format, and historically after the gauntlet of the Pharmacology and Immuno/Hematology P2-1st semester, we lose 2-3 people a module up until rotations begin. P2-1st semester is partly to blame because of an old school hardcore professor who shares no sympathy for any student failing. I've also heard about students failing rotations here, which generally doesn't happen.
The recently class of 2008 here started with around 80 and graduated only 50.
From what I understand, Wayne has one of the highest NAPLEX pass rates. One graduate from here last year scored the highest overall score in the nation. Our average incoming GPA is over 3.6 as well so its not because of them letting in anyone. It is a really difficult program and I'm glad its challenging.
