Each year in the U.S., 2.9 million young people graduate from high school, 70 percent of whom are heading for college. They've read the catalogs, spent months filling out applications, been accepted, chosen a school, shopped for dorm accoutrements and packed up their childhoods. But then what?

How do you come out ready for the "real world?" 12 college students from all walks of life and different types of colleges and universities share the insider knowledge that isn't in the school catalog: what made it work for them.
