<p>I have a friend who was a straight-A student in high school and went to UC Berkeley. An English teacher kept trying to down grade her in some effort to break her perfect record. She complained bitterly, but it did not seem she had any recourse.
Then, the teacher assigned the class a poem to write. She wrote a poem, put it in an envelope, and handed it to her guidance counselor on the day the assignment was due. Then, she found a published poem written by a somewhat obscure but well regarded poet (well regarded in academic circles) and submitted it as her own to the teacher. He gave her a low grade. (This was in the 1980s- years before the internet and search engines.) At that point, she went to the administration, proved she had written a poem and completed the assignment by the due date, and proved that this English teacher had given a published poet a low grade on an 11th grade assignment.
She won. The administration allowed her to take an “independent study” with another teacher rather than continue to be subjected to a teacher who was out to get her.
Nothing happened to the teacher except he had his pride hurt.
I would not advise you to do what my friend did, because you could be accused of plagiarism. Keep a very careful record of everything. Maybe you’ll be able to trap him in a lie.</p>
