Viewing grading history
Grading history allows you to see who graded each assignment. For quizzes, you can view historical data for any regraded quizzes. If you've changed the grade more than once, you will only see the last two scores you gave.
1. Click Grades on the side navigation.
2. Click the gear.
3. Click View Grading History.
You will see a list of the people who have graded the assignments and a summary of changes.
