My first semester in grad school, we had a HORRIBLE professor who DID NOT GRADE ANYTHING. I am dead serious. We wrote all of these long research papers, and she NEVER graded them. She never told us our final grade either (she let us find out what it was from the school's online system). Guess it didn't matter much anyway since she obviously had to make up this magical grade. When we all emailed her asking for her to explain how she came up with our final grades, she never replied. (This was a distance ed course so we couldn't go beat down her office door, unfortunately.) Needless to say, we went straight to the dean about her. :|
