Very warm atmosphere. The admission team greets you as soon as you walk in the door. Once everyone arrives, you listen to a presentation on CUSOM for about an hour. Then you go upstairs and have three 30 minute interviews, I had one with the assistant director of admissions, a PhD, and a DO. All were so friendly and asked fair questions. I would just know your application well and relax. The rest of the day was pretty relaxed. We had a tour and lunch with an MS4 and had a financial aid presentation. I think it lasted until around 2?
You are naturally going to be nervous, but just remember that you'll see what I mean when you interview. You'll do great.
