We don't have a study hall at our school. We just have the Library to do any work in the morning, lunch, or for a little after school.
Also, my Math teacher only gives five points on homework, and checks if you just did the work. If you didn't, no points. Simple as that. We also go over the work. My World History teacher is so cool, though. :D He doesn't have us turn in assignments until two weeks later I think, but we still have to have those assignments for when it's time to check them, and get our grade for them. We also watch a lot of funny videos in his class. Mostly SNL skits. Except that one time, he added a scene from Billy Madison into our notes.
