I am using a weighted grade book. I would also like to have a column that shows the students total points. I set up the course so that there are 1,000 points possible, but I use the weighted grade book so that I can get the system to throw out the lowest score from one group of assignments. I like having the points because it gives the students (and me) a very easy way to spot check the grade. It also allows them to see exactly how many points they need to get the next higher letter grade.
