Yeah. Sometimes on interview day, your head isn't in the tour/info sessions. So the open house is a chance to get to know about the school, check out the facilities, and ask questions. This will help you decide if RVU is a good fit for you, and give you a stress-free day to ask any questions you have. It might even give you a little something to talk about in your interview.
When I was deciding which school to go to, it helped me a lot to check out the campus, meet the faculty and students, and get a feeling for the overall atmosphere. Granted, when I was interviewing, it was 5 miles away from the half-completed building. But I still learned a lot just by talking to people.
Does this help at all? I think if you're at all interested in RVU, and you're not too far away, you should definitely go.
Alright, that's enough out of me. If you have any other questions, let me know-
