I did not reveal myself and was too shy to ask around haha. I didn’t think I would say that I had fun on interview day, but I did! We're not allowed to discuss specifics of the MMI, but I will just say that I appreciate the staff who made sure we were at ease and comfortable throughout the day. They really want you to relax and be yourself. I like their approach to an integrated, collaborative, and independent learning curriculum. I also like how they seem serious and invested in their mission to address the needs of surrounding underserved areas. Overall feeling about the school is very good. The only factors for hesitation I can think of are the tuition and uncertainties with a new school at this point. But if this was the only school to take me, I would be more than happy to attend.
I know some people have said you can walk into an MMI without preparing at all, but I still recommend reading the MMI book by Dr. Desai, only to get a gist of the MMI’s format and the overarching theme in how differing stations and questions look for the qualities, skills, and traits of a good physician, but it’s pretty much impossible to rehearse or anticipate specific cases. I like having a general idea of what to expect, but don't worry too much about something you can't really study for.
I didn’t get to write down exact numbers, but during the presentation they showed stats for the class that entered in 2018 (which haven’t been released on the site yet): ~3600 applications, ~600 interviewed, ~150 matriculated. Avg cGPA 3.5, avg sGPA 3.4, avg MCAT 502. We were told that post-interview decisions would come in ~3 weeks. Good luck to everyone who was there with me on interview day, and good luck to those earlier in the application process!
