It's hard to grade a non-research paper that way though. For example, that class was a Humanities 101 class. We were supposed to do some analysis of whatever book we'd just read. So good grammar is not a large part of the grade, and factual correctness is not easy to check when you could "hit the stacks" and cross-reference any other books in the library. The teacher (who was good by the way, I'm blaming the system not him) would grade the paper based on how "good" he felt it was, based on your apparent understanding of the material, and your ability to think well and express your thoughts clearly.
