You don't. You have really fricking easy classes. So easy that you think you can slack off. Then you fail them all, lose any funding (parents, scholarships, student loans, etc.), and have to flip burgers at Burger King for the rest of your natural life (plus a touch of your un-natural life - you know, like 10,000 years or so).
I wish my room wasn't such a disaster area-level of a mess.
