Do you have to agree with your professor?

 "In response to the question, "On my campus, there are courses in which students feel they have to agree with the professor's views on the topic at hand in order to get a good grade,' 44.3 percent said yes. The answers, of course, don't prove that such agreement with a professor is in practice essential to being graded fairly, but the very fact of that perception should be of the most urgent concern to all faculty who care about critical thought and intellectual diversity...I hope that ACTA will keep the public informed of the response (or non-response) of colleges and universities in Illinois to that devastating finding."

That's Professor Alan Charles Kors, Henry Charles Lea Professor of History, University of Pennsylvannia, quoted in the Association of Trustees and Alumni (ACTA) journal in response to ACTA's report card on higher education in Illinois.
