As a man who left school not that many years ago, I'm amazed how well I feel this describes the situation back then. I remember being frustrated by grades being all about who (I then thought) manipulated the teacher best by acting like a "Good Boy/Girl". By being neat and by being timely rather than the one who knew what the grade requirements asked of the students. I wonder, is the article true or does it just appeal to my feelings?
