I realized (well a student pointed it out) that the HW grades were posted before the due date, so I re-posted the HW grades. Grades went up or down as much as 4-5 points.
The score I see initially is total points earned NOT % score, so be careful to not look at your score of 90 and expect a grade of 90%. The grade is out of 138 points so a score of 90 points is only a 65% grade.
