Should I retake the class or ask for partial credit?

I'm taking one class in community college which I was already near failing halfway through the semester. The teacher does not seem to like my work even though I think I did a good job on my essays. I stopped caring in the middle of the semester and haven't done any work for a couple weeks. My missing assignments have significantly lowered my grade to a 44%. There's only one week left. What do you think I should do?
