I went to nursing school at Uof A, and I can tell you that when I was there we had "Interprofessional Seminars" that included medical, nursing, pharm, public health in groups learning/interdisciplinary respect exercises. However, I came into contact with medical student MUCH more frequently just in random non-academic encounters in the hospital, UMC cafeteria, around campus, playing intermural sports, and out on the weekends. All of the health profession schools are right there crammed together and UMC is a big teaching hospital, so there is bound to be some unofficial mingling. That being said, as one of 10 guys in a class of 95, most of my friends were girls and I got a front row seat to their dating lives. As a general rule, they were not interested in dating medical school students (many of them stated things like how little time they would have for them, debt, etc.), but I would have to have another set of hands to count the number of random interns and residents that they ended up dating.
Also I have my own question....is there a benefit to attending the second look weekend if you know for sure you are going to the school? I mean UofA was my first choice and after I got accepted I cancelled my other few interviews, so I don't really need any convincing to go here.
