Once I publish my Quiz, how do I make additional changes?
Once you publish a quiz and make it available to your students, you can make changes to the quiz. However, students who have already opened or completed the quiz will not see any changes you make, which may affect their grades. If necessary, you can use quiz regrade to edit certain types of quizzes.
