Congratulations on your acceptances!!

About the Community College option, I do go to one myself. It is definitely NOT like high school. If anything I think Universities are more so. Most people at mine are there for going to college to get a career... not for the party life. People are mature, classes (I've heard anyways,) are a bit easier than University classes, and it's cheap!
I do plan on switching to the University of Utah when I'm done with my first two years for nursing school though. CC is a nice place to begin with.

Good luck on choosing. I'm sure whatever you decide, you'll like it!
