| - | The percent-to-lettergrade score conversion here is determined by computing the averages of the percent-to-letter grade conversions above. That is, the 80% dividing line between A and B comes from averaging the 85%, 90%, and 70% dividing lines between A and B on the three exams (which comes to 81.65% and is rounded down to 80%). This algorithm assures that if you just barely got an A on all three exams, you'll just barely get an A in the course. | + | |
