"What happens when a professor decides to take an easy class seriously and teach it as a difficult class?"

"I was once given that task, and the students revolted. When we went over the syllabus on the first day of class, several students told me that my class was supposed to be their easy class and that they would have to drop it and find another. I told the students that my chair had asked me to make this class more academically rigorous. They just looked at me in disbelief, and several students did drop it."

The problem of "easy" classes. The discussion continues here.
