KB1094 - Show a "progressive" total in students' User reports

My student completed only one activity out of 5, but his course total shows 100%.

How do I show a more "progressive" course total?

Step-by-Step Explanation

1. From the view menu in the gradeboook, select "Categories and items"
2. At the top line there is a folder icon and an edit icon on the right, click the edit icon
3. You'll then see the title "Grade category," the 3rd item is "Aggregate only non-empty grades."
4. Uncheck this.
5. Save.

Another Explanation

By default, only non-empty grades are aggregated, the others are ignored. However, you can change this setting as well as others that affect the course total, by turning "Editing" on in the grader report, and clicking the "Edit" icon next to the course category (the very top row of the grader report).

You can untick the box "Aggregate only non-empty grades" if you want to show a more "progressive" score for each student. Their empty grades will count as a 0 and will be counted in the course mean/total.
