My professor replied, he says he can't do anything more because the grades were turned in, but I'm not so sure he really read my email and the accompanying policy quotes because the grievance procedures - which include grades - say to start with the instructor in trying to resolve it, which suggests to me that the grade can be changed. This was his first semester teaching so I'm guessing he doesn't really know the policies, but I distinctly feel like writing him again won't be helpful. So now I get to go to the second step, which is the unit head. Not sure if that means the program's director or someone else - pretty sure there's a non-adjunct prof who oversees those courses so it might be that prof. I have to find out Monday. Later that day I'll see my counselor, who I haven't seen in a long time. I wish I could see her sooner, before I go to the department because I really would love her feedback on this, but I'm sure she doesn't have any earlier appointments and I can't put it off - I'm currently at risk of being kicked out of housing, I expect they won't say anything until Monday and at that time I'll explain the situation and hope for the best...
