It depends on what college you go to. I breezed through high school I missed over 100 days of school my junior year and only had to go to class the last period of the day my senior year. I gadiated with a 3.7. I was fucked up in high school though I did lots of hard drugs and didn't care about anything. I did a little stint at a community college and lived in Florida for awhile. Now I am back here going to Ohio State and holy shit, wake up call, real world dead ahead. You actually have to study, and go to class or you will fail. Even the blow off classes are kinda hard. It's way different, I am glad I took time off before I started though because I would never have been able to handle it straight outta high school. Just be ready to take responsiblity and work hard or you won't make it.
