Canvas offers a regrade option for both New Quizzes and Classic Quizzes. Note that regrading only applies to completed submissions; wait until all students have submitted to regrade quizzes. For New Quizzes, all questions can be automatically regraded except Essays and File Upload. For Classic Quizzes, only Multiple Choice, True/False, and Multiple Answer questions can be regraded.
