That's what my sister is doing, but also Psychology.I graduated from the University of Iowa last year, which is right down the street from you! I really liked the school, but I'm glad to be done It's a research based school so just about every class you take is going to require a lot of reading, and reading of research papers. That was the worst part, but I was a Sociology major which is nothing but research so I had it ten fold! Sociology was an awesome major, but you have to be interested in that sort of stuff.
I looked into Iowa State Uni., what's your views on it? I know you didn't go there, but, it's worth asking! haha
