1. Login as a teacher, edit the settings for the quiz and set the grading method to 'Highest grade'.
2. Check that the grades in the gradebook are the highest grades obtained from all attempts.
3. Edit the settings for the quiz and set the grading method to 'Average grade'.
4. Check that the grades in the gradebook are the mean grade of all attempts.
5. Edit the settings for the quiz and set the grading method to 'First attempt'.
6. Check that the grades in the gradebook are the grades for the first attempts, and all other attempts are ignored.
7. Edit the settings for the quiz and set the grading method to 'Last attempt'.
8. Check that the grades in the gradebook are the grades for the last attempts, and all other attempts are ignored.
