Hi @MPederson ,

Instructors cannot unsubmit a quiz attempt once it has been submitted in Canvas. The system does not support an "unsubmit" or "delete submission" feature for quizzes. If a student submits a quiz in error, the instructor must provide an additional attempt for the student, but this will be a new attempt for the entire quiz rather than allowing the student to continue editing or resuming the original submission.

Once I publish a quiz, how can I give my students extra attempts?
