Bio Frustration

I hate how I am conducting myself in Biology class, this semester. I don't like to, but I often fall asleep in class; or I don't even pay attention in class and just sit there with a blank stare. I know I'm failing right now, but not even that is pushing me to try harder. The only thing I have working right now, looking at the powerpoints posted online. Even though my professor uses them during class, I find them boring. But when I get home I play some music and start looking through the powerpoints, myself. I hope it works out in the end with a decent grade, instead of a failing one.
