From all the schools I applied to, WVSOM's application process seems slightly different from the others. They do not request a supplemental/secondary application (or fee) unless they want to interview you. I had my interview earlier this month, and this is my understanding of their process:
If they want an interview, generally speaking they are willing to work with your GPA/MCAT. If you did poorly in either area, they will want to know why. WVSOM gets 3000+ applications a year. They interview around 500-600. They accept roughly 350 of those, and of those 350, roughly 200 commit. There is no "fixed number of spots". If you get an interview, your chances are good.
I will say from the 24 hours I spent in the Lewisburg area for my interview, the area is unbelievably pretty, especially the drive between Lewisburg and Beckley (which is 40 minutes or so west). The town, for it's size, exceeded my expectations as far as places to shop and eat. The residents we spoke to (waitresses, etc.) were all very friendly and seemed to like living in the area. The students we met on our tour all seemed happy. The admissions staff, Angela and Annette, have to be the nicest college admissions people in the world. We also met the Dean of the school, and he was also very nice, and made it clear that he was accessible to meet with students etc. Everyone I met seemed to be in good spirits. I'm convinced there has to be something in the water.
Obviously, I got a good vibe from the school, and when I pressed students to tell me something bad about the school, high OOS tuition was the only thing they could tell me (I believe WVSOM is second highest cost OM school in the US). That said, from what I saw on my tour, that high tuition has gone right back to the students in terms of facilities, which were state-of-the-art. Anatomy Lab, Sim-Lab (16 sims, some tetherless), and lecture hall were all well designed, and new students receive a laptop pre-loaded with requisite software, theirs to keep.
