Sick of Studying!

I have studied at least 2 hours daily for an exam I have Thursday for about a week, and I am sick of it. I think I have gotten to the point where I could care less about how well I do, I just want to get it over with. Doesn't that defeat the purpose? Right now I just want to get my mind off of it for awhile before I start dreaming of brief therapy. It is already squeezing itself into my conversations with people. I am sorry but that is too much. I need to do some surveys or take some stupid quizzes or something.
