Scores for Exam 3

In a dozen years of teaching this course, never have I had a class that did more poorly on electric potential integration than on electric field integration.  Until now.
Fully 50% of the class scored below 3 points on the "potential integration" written question, which means that they didn't even get the points that could be had without doing any integration.  What the @#*&^# is going on?

A small score adjustment was applied to this exam.  You will find your effective score circled at the bottom of your exam.  The overall resulting class average was 69.7%, with a median of 67.2%.  Class grade distribution is below.

Class grade distribution for the Exam is to the right.  The bars of the histogram correspond to the letter grades (A, B, C, D, and E). To see how to interpret numbers, go to this link.

Keep in mind that, in this class, homework scores are typically higher than exam scores.  The second histogram shows the class "extrapolated grades": combined performance on exams and homeworks.  In particular, these extrapolated grades include the homeworks 0 through 13.

Your personal combined grade can be found on the Course Home tab in myCourses.
