To enable Assignment Groups Weight in your course, you will first need to create assignment groups that will correspond to each group weight needed. After the assignment groups are created, you can click on the three vertical dots in the upper right-hand corner and select the Assignment Groups Weight option from the dropdown menu.

The group weights can then be applied to each assignment group. After the percentage is assigned to each group, you can click the Save button to finish applying the Assignment Groups Weights.

If you want to weigh an individual assignment, such as a midterm paper, you must create an assignment group to house the single assignment.
