Submission Details is another way to view your quiz results. Displayed in the sidebar, submission details will show the time it took to take the quiz , your current score , and your kept score , which is the score that Canvas records in the Gradebook.
Note: If your current score includes an asterisk, some questions have not been graded by your instructor, such as essay and file upload questions. You can also view the status of your quiz on your Grades page.
Submission Details with Repeated Quiz Attempts
For repeated quiz attempts, the submission details will continue to display the current score  and the kept score . However, in this case, the kept score is assigned by your instructor and can either be your latest quiz attempt score, the highest quiz score, or the average of all your scores. The kept score is indicated at the bottom of the submission detail area .
