My English teacher is a nazi..........................…

she gave me a 0 percent on my final just because i wrote in green ink. I would understand a point deduction but she straight up gave me an F. I made 200 flash cards for this test by hand and studied all of them. I was stressed and didn't focus on the color of my pen. Do you think the principle would be able to do anything about this, even though this stupid class rule is written in her syllabus?
