Vanderbilt or UVA

I’m completely torn between these two schools. I haven s seen Vandy yet, but I’m going this weekend and hope that will help my decision. I’m planning on majoring in Psychology, but I know that will probably change because I really don’t know what I want to study. I’m more concerned on the social scene of these schools. I have heard that as diverse as Vandy is, it is very segregated into undiverse groups. Please offer up any information that could help me make this decision, I don’t wanna regret making the wrong decision.
