So I am taking a college class and the professor is requiring students to attend everyday from 5-9pm. This is in addition to the actual class that is from 9-10:40. This session from 5-9 is not scheduled anywhere and he decided it. It is actually finals week at my school, and we are only supposed to take our class once this week for our final. My question is can a professor require students to attend class outside the assigned hours? Also, he says if you do not attend these sessions you will not pass the class.
