Creating Weighted Groups for Assignments
You can weight final grades based on assignment groups. Selecting this option assigns a weight to each assignment group, not the assignments themselves. Within each assignment group, a percentage is calculated by dividing the total points a student has earned by the total points possible for all assignments in that group.
In the course navigation, click Assignments.
Click the settings icon, and choose Assignments Groups Weight.
A pop up will appear, click the Weight final grade based on assignment groups checkbox, and click save.
