Add a correct option to MC question after students have taken the test

[VictorFerreira]

After delivering the quiz, I realize that a fair thing to do would be to make one of the incorrect answers on a multiple-choice question correct, and regrade the test with the additional correct option.  Can I do this in Canvas?

Hi Victor,

There is an option for regrading multiple-choice questions in Canvas, and the regrade includes the option to award points for both the previously correct and new correct answers.  See https://community.canvaslms.com/t5/Instructor-Guide/How-do-I-regrade-a-Multiple-Choice-quiz-question...
