Categories can be used in the Gradebook to organize activities by unit or by type (e.g., assignments, discussions). They also allow for the weighting of a particular group of activities; for example, all quizzes together might be worth 5% of a total grade, regardless of their total point value.
Creating a category in the grade book
Go to the course homepage.
Find the Administration block:
Click Gradebook setup.
Select Gradebook setup from the drop-down menu in the upper right.
On the Gradebook setup page click the Add Category button.
Enter a Category name.
Scroll down and click Category total to see the options.
Enter a Category total name:
This should match or include part of the Category name. Example: If the Category is named “Assignments” then type “Assignments Total”.
A Category total name is not required, but is highly recommended.
Choose the remaining configuration options as desired.
