    There is some correlation with not doing the MasteringPhysics homework and doing poorly on the exams. For the set of 32 students whose homework average is less than 80% (often because of not doing the latest assignments) their exam average is 68.6. For the set of 107 students who are getting 93% or better on the homework grade, their exam average is 76.4. Doing the homeworks will not guarantee that you will do very well on the exams, but not doing the homeworks makes it more likely you will do more poorly on the exams. An 8 point difference in the average for the first two exams is worth almost a two level jump from a C to a B-, or a B- to a B+ in the Mid-Term grade assignments.The correlation figure is shown below.

    Third Exam version A solutions
    Third Exam version B solutions
    The exam grades were scaled up by 8 points in order that the average of the third exam (=70.4) match better the average of the second exam(=72.4). The exam averages showing in the Oak system will be somewhat lower because a few students have withdrawn, and their grades are being carried at 0. The Oak system also shows a numerical average for the letter grades, which must be based on some conversion of the letter grades to a numerical value. The actual fact is that the class GPA for the March 31 set of grades is 2.78, based on 4.0 for an A, 3.75 for an A-, etc. As mentioned in class on April 3, the class GPA on March 31 was about the same at the mid-Term break.
