Unlike the submission folder, there is no group setting for Quizzes.
The only way group quizzes is possible in D2L is to have one student from a group take the quiz, their grade would be automatically recorded, and then you as the instructor would need to manually input that score for the rest of the group members in the gradebook.
It is possible to sort the Grades area based on group enrollment, so that would help to speed the process:
- Go to Grades
- Enter Grades
- Next to “View By:” change this setting to groups
- Click Apply
- Then select the group and click Apply again
