Note: One student amassed so many extra-credit homework points (in addition to having done well all along) that he was guaranteed an A for the course, regardless of score on the final or the grade-scale for the final, so he was permitted not to take the exam. It is safe to assume that had he taken the exam, there would have been one more A or high B on the list below.
