In my Grade Center, I have a weighted column, in which I have four categories:

Assignment = 50%

Test = 20%

Quizzes = 10%

Final Exam = 20%

I add extra credit points to my Assignments category, but the weighted column will not calculate for the extra credit points: i.e. if Assignments has 100 total points, and student has 120 points total, the student's Assignment grade should be 120%. My weighted category displays no more than 100% for this student.

What am I doing wrong?

Unfortunately, you can't just add an extra credit column to a category. You have to add two columns- one for extra credit and a new one for the category average plus extra credit. Then, substitute that new category average column for the old one in the Weighted Total column.

We give our instructors these handouts: Extra Credit in a Percentage-Based Grade Center, Extra Credit in a Points-Based Grade Center
