OP here, just for all of the people talking about self plagiarism, I checked. My university does not have that clause anywhere within the rules. I read through the entire thing and even checked with the legal department. I'm sure they will put it in after this. I have gone to the dean and they have forced the teacher to drop the case and give me the grade I deserved. They also decided, due to suggestion of the department head, that the department head himself will be grading everything that I submit to that teacher for the rest of the semester, and that I will not be able to take classes with that teacher anymore. I'm sure they will be evaluating their plagiarism rules more, and putting in a clause for self plagiarism, but we will see what happens. Luckily, I only have 2 more semesters there before I'm out of that school for good.
