Group activities into categories to improve navigation
Categories can be used to group similar items together, such as weekly quizzes or assessments that don't contribute to the topic total. Categories can also be used to calculate a grade when some of a group of assessments contribute to the topic total
(e.g. the highest 3 out of 5 quizzes)
In the gradebook, click on the Setup tab, then the Gradebook setup link.
Click on the Add category button, which will appear under the list of assessments.
Give the category a name, and click on the Save changes button.
To move grade items into the newly created category, select the check box next to the far right of the item (A) and use the Move selected items to menu (B) to move the items into the category you just created.
