Should I report a class to the Provost's Office?

I work for a University and they also pay for my tuition as a graduate student for business since I work there. I am currently taking a finance class and an elective class, so I only have two more classes after this and I will graduate. I’ve always been an A and B student but this elective class I’m really struggling with.

There are four different law professors in this negotiations class that take turns teaching and grading each week. The grading is very inconsistent, they say one thing and then another, they immediately hand out case studies for outlines which we have never done before, they have us do assignments before even learning the material. They are all very harsh graders, particularly one. I usually get A’s and B’s but have been averaging C’s on my paper but one harsh grader just gave me an F.

This is not just me but several other students, the whole class pretty much, are very concerned about their grades and feel the same way as I do. We’re not idiots, many of us have maintained a 3.0–3.8 GPA and have scored D’s and F’s on our last paper. The grading is very unreasonable and has all of us extremely upset. An elective course where you write a paper on negotiations should not be this challenging, it’s not like we’re going to be lawyers!

I work with the Provost Office, I am seriously considering reporting this class to the department. I’ve never received an F and I don’t think I deserved it. Several other people who are A students and even a girl I know who gets straight A’s got an F as well. Can they really fail most of the class?
