Sometimes instructors discover that a question's answer choices or grading method are faulty after students have already attempted the quiz.
Quiz questions can be edited after the quiz has been taken, and then the quiz can be regraded to reflect the updated question settings.
1. From the Edit Quiz screen, locate the question that requires editing and click the gear icon.
2. Make any appropriate changes to the question, and Save the question.
3. Click on the Quiz activity from the main Moodle Page.
4. Click the word Attempts followed by the number of attempts made.
5. Click the Regrade All button to regrade every attempt with the updated question information.
6. If only specific attempts require regrading, check the checkbox beside those attempts, then click the Regrade selected attempts button.
7. The Results grid will draw a line through any grade affected by the regrade function and report the new score.
