I'm getting a D in one of my classes.

Is it still possible to graduate with one D? I'm not continuing my education due to too much outside stress. I just want to finish this semester and be done. The one exam I had, I failed and the quizzes weren't the best. I did get a good score on the assignments but that was not helpful. I still need two other assignments to be graded but I know I won't get 100% on them. My last hope is the final and I would need an 85 to pass with a C. I'm going to study but with the way the quizzes have been going. I don't have much hope in passing with an 85. Maybe a 70 but not an 85.
