How do you ague with a teacher?

If it's about grades then you must get your grade you deserve. For example, my teacher gave me a 100 percent, but in the grade book she wrote zero. What i did was talk to her, then start saying that it is not fair. She did not even one time say sorry! Anyways, if a teacher messes up your grade, Then Tell The Teacher. It's the 3 T's.......Tell The Teacher that she messed up your grade.
