I'm doing online classes and had to do short essay answers for an assignment for a class last week, which is common for one class in particular. I usually get brief/ generic feedback at the end explaining my grade. Typically something along the lines of "demonstrated competency." or "enjoyed reading this." With the last time, one of the questions asked what I had learned form the chapter. I highlighted what I didn't learn and asked the professor a bunch of questions. He still gave me a perfect score and left a comment that I demonstrated proficiency. Obviously, he isn't reading anything I write. How many teachers/ professors do this?
