Can I editing Quiz Questions that have been answered in a quiz?
There are cases when you may discover that a question in a quiz that has been answered isn't correct!
Most users will go and edit the question so that the answers are correct, and then typically do a re-grade.
Here's some guidance from Tim Hunt (maintainer of the Quiz Component in Moodle) that is worth knowing:
- Doing a regrade after changing the number of answers in a multiple choice question (i.e. from single answer to multiple answers) will delete the responses to the multiple choice question.
(Afterall if there are now more than 1 answer, how could you know what the student would have chosen if they'd known about it at the time). - Changing the question value (maximum mark / marked out of) is completely safe. It does not even require a regrade. The scores are re-calculated immediately.
- Changing some elements of a question, e.g. the grade of each choice in a multiple choice test, or correcting a typo in the question text, is safe, but does require a regrade.
Changing the type of a question: don't do that.
How can I embargo quiz grades until a certain date?
If you want to allow students to do a quiz, but not see their grade until a specified date you can do this by setting the following options in the quiz's settings:
- Timing / Close the quiz: Set to the Deadline for quiz submission
- Review Options / During the attempt, Immediately after the attempt, Later when the quiz is still open: Uncheck Marks
- Review Options / After the quiz is closed: Check marks
- Restrict Access: Create a Date restriction: (Until (deadline set in 1) OR (date grades to be visible from))
