What's up with that?

I wake up at 7:00, which I have decided to do that even if i don't have an 8:00 class, and go to my SOC 101 class. I'm not fussing mind you. On little website calender that my teacher has made it says we will be in class from 8:00-8:50am. We were there for a total of tweenty minutes, then he let the class go. Now I have more time to do his quizes that are due tonight, but I kind of makes me worry, what kind of class this is. Do I work hard in that class, that has a lot of busy work outside of class like my other classes, or worry about my other classes and just do enough to get by?
