Last Tuesday afternoon 216 brave calcunauts (and one interloper) took exam four. Three calcunauts with medical excuses will take a makeup exam next semester. The mean is 70.3 and the quartile scores are 61, 74, and 84. For comparison the results from the past two semesters are:

Strange but true: someone not enrolled in the course took the exam and scored a 42.

Spring 2016: mean 63.8, quartiles 54, 65, 76.

Fall 2015: mean 69.8, quartiles 62, 73, 82.
