How will college life be for me at University of Wisconsin or University of Michigan?

Answer 1

It completely depends on which campus you will be at. In Wisconsin, Madison is the party school, Milwaukee tends to be the people that couldn't get into Madison, Green Bay, La Crosse and Stephen's Pointe are both top-notch schools, and Whitewater is more rural, if you don't want to live in a big city.
Unfortunately, I don't know anything about the Michigan system. The best way to figure this out would be to go and visit the campuses, sometime when school is in session so you can see what it's really like there for students.
Good luck!
