Grades disappeared after individually assigning
When a quiz is individually assigned to a student, the assignment is treated as a separate instance for the selected student. As a result, grades for other students may temporarily disappear from the grade book. After the individually assigned students complete the quiz, restore all student grades in the grade book.
- Navigate to the course
- Click the gear icon for the quiz and select Edit.
- From Assign to, delete each student's name.
- Click Save Changes.
