Missed cl all semester?

Im in college and in the accounting program and I missed a lot of my cles. Finals are coming up and Im not even going to write them. I know I screwed up but, I want to go into science, next year. I dont know what college well take me if I flunk out. My GPA is very low because I never go to cl, and I hate my degree so I dont try, and I party all the time. But Im slowly turning my life around. Anyway, should I go drop out before finals, well that help me get in next year, and should I upgrade in the summer to bring my GPA back up. What should I do?
