I am an undergraduate student at a university in the US.
Unfortunately, I have a concern regarding one TA of a class I took this past year. This individual insults other students in the university during his TA session, and I also found out from other people that this TA has been talking to other people (not just the professor and TAs for the class) about people's grades in the class.
My question is, is it within my power to lodge a formal yet anonymous complaint that will be taken seriously about this?
I am concerned about my identity becoming known because this TA is a strong student, and seems to have a lot of power in the department (and is close with the professor teaching the class).
