I have administered a quiz, and all the students have taken the quiz and it was automatically graded. However, one of my (numerical) answers that was used to grade the quiz was wrong.

How do I go into the quiz, change the answer (i.e., edit the quiz) and have Canvas regrade all my students. At least regrade that particular problem, using the students’ original answers.

This is because many of them typed the correct numerical answer, but were marked wrong because I had quoted the wrong correct answer.

Thanks!
