To categorize several Activities at once, you can access the Bulk Edit feature.
Click on the Gradebook tab. In the top toolbar, click on the three dots and choose Bulk Edit.
With this feature, you can change the category of an activity, assignment, quiz, or test, set how many points it’s worth, change the grading scale or rubric, and change which grading period it counts in.
Please note that Factor is how many times it counts in the Gradebook. By default, all Factors should be set to 1. If you would like a test or exam to count twice, for example, you would set the Factor to 2.
