Letter grades for individual exams are not recorded; letter grades at the end of the course will be assigned based on total points out of 460 (4 100-point exams + best 3 20-point quizzes). The average on this exam is almost exactly the same as the average on Exam 1 last spring. This letter grade distribution is only to give students an idea of where they would stand on this exam, if letter grades were being recorded.
