Question for chemistry students...should I drop chemistry?

It's mid semester and I am sitting at about a 50% in chemistry overall. I admit that I had poor time management, but the material is also really, really difficult. If I buckle down, manage time well, and get tutoring is there any hope of my getting a C? I know you can't tell for sure with out knowing how the teacher grades, but I can say that his grading is pretty straightforward and I have the same number of ignments and tests in the 2nd half of the semester that I had in the first. So in theory if I make 90s the rest of the semester, I would squeeze by with a C. But knowing chemistry and how hard that is, would it even be possible to do? I'm a senior and have never had to drop a cl, but I can't flunk this. What should I do?
