1. Ask friend from other school to act as class representative (This is important, He must be unaccountable.)
2. Get professor's thesis and score it.

"Professor Warnsdorf, your thesis (Wave with the thesis.)
got 27/100 points. Therefore YOU are not worthy to teach English."
4. Then entire class will leave the room.
5a. Most of time prof will come to senses and stop this idiocy.
5b. If he continues to assert that there is nothing wrong with online testing quit the school.
