Very mean teacher

I've had the experience of having this so called "bad teacher" who you could not do anything about in the past at least once, and I have a few honest suggestions on how you could handle the matter more easily.

1) Explain the entire situation to your parents. I personally think that you haven't done enough to truly get your parents on your side. When I had to face a similar situation, my parents initially thought that I could easily handle it myself. If your father or mother attempts to pull a degree-string on you, saying that you should be in the top of your class, then you'll have to diplomatically receive their attention. Point out that unfortunately, there are some experiences in the world that cannot be handled without support from peers. Say that this is a final straw: the professor is doing unethical things in order to try to pull down people's rank. Make sure you tell them that people who complain to the department head often have their grades lowered in other categories arbitrarily.

The reason for having your parents on your side is simple. It is much easy to handle difficult situations through suggestion from your parents, and it certainly helps calm you down when you have to directly deal with your adviser. It is worthy to note that you must tell your parents that they HAVE to support you at this moment, because simply saying "you can do it" is not entirely constructive.

2) Determine the risk you're willing to take. You must make the decision for yourself: is the teacher truly inciting aggression and doing unethical activities in order to increase or decrease grades? Are you guaranteed to fail the course? These questions come into play when you attempt to find the solution. Don't be afraid of the punishment and procedures that go into investigating these grade-decreasing accounts.

3) Craft a solution determined from your thoughts above. If indeed it is your last straw, you must absolutely talk to your faculty head. Unfortunately, starting a movement or using the student's union is not going to suddenly change the way the faculty works on grades. Departments usually follow student suggestions but only gradually AFTER the semester has passed. You must absolutely do the following:

Before you go to the department head, you must have paper evidence of the grade you got in each subject. This may come from directly confronting the teacher and asking him to print out a FULL grade report or a list of grades on a single piece of paper, or from keeping all of the assignments and grades you have had from the past. You must go to the head of the department, citing that other students who have in the past complained to that head, have had their grade decreased, and that you wish for other faculty or the department head to grade future projects instead. You must tell the faculty head that you have saved a list of grades, and wish to receive a full summary after the grading period has finished.

These are the types of rules that department heads should ethically follow if a complaint arises with a student, and you should be able to at least strike a bargain or deal with the head (or you're really in the wrong school and need to either switch majors or schools immediately)

Jam it back in, in the dark.
