The "classic" Quiz tool had an option to moderate a student quiz by unlocking the quiz for the next attempt.
The classic instructions read:
"If your quiz is locked because of accessibility dates, you will need to unlock the quiz for the student by clicking the manually unlock the quiz for the next attempt checkbox ."
This worked even when a student hadn't taken the quiz AND when the assignment had closed. This was very useful for students who had been granted extensions. I could go in and just open the quiz for a small number of them (I have 240 students).
However, I can't find that functionality in New Quizzes, which is very frustrating. I see that there is a "Reopen" button when I go into Moderate but it only appears if a student has at least one attempt. I can find no way to unlock a quiz for a student who was granted an extension and so will, a) be taking the quiz after it is closed; and b) has not had any previous attempts.
This was a very useful feature so that I don't have to open the entire quiz up (to students who did not have extensions).
Does anyone have a fix? Can the Canvas folks add that feature?
