Maybe they are trying to teach good manners. Even though you don't really have a choice in doing the homework it is still nicer to ask then just say do it.
One time they were also a student just like us !!! They are just taking their revenge
so they repeat the things they learnd at school and actually should be able to do it later again
There's a good chance that the student will learn something for a change .
Your welcome , This professor has seen much .
they get paid for
So that they can learn. He is just doing his job.
Because it's their job to teach the students.
Not sure, but they would always get mad at me for some reason when I would start on it right before class.
At least to study at home.
Thanks for BA
