Regrade a quiz in Canvas
If you accidentally published a quiz that needs to be corrected, you can use quiz regrade to edit existing quiz questions and have Canvas recalculate student grades. Please note, the regrade function currently works only with the following question types: true/false, multiple choice, and multiple answer. For full instructions related to the regrade feature, see What options can I use to regrade a quiz in a course?
If you need to adjust points for a quiz that uses questions types not covered by the regrade function, you can use the “fudge points” feature in the SpeedGrader.
