Can a college professor fail me for not submitting assignments in another portal other than school portal, in which I am imposed to pay $224. I am taking a Spanish class and our professor is imposing us to purchase a Spanish portal named VHL central. Is that legal in NJ, is any law preventing her from doing that. She said is the department decision so I have to pay for it, or otherwise she will fail me. Is any law that protects students from purchasing.
