How do I remove a quiz grade and allow a student to take the quiz again?

I have a student, who went to take a quiz and a grade was already there in error. I want to know how to remove the previous grade and re-open the quiz so this student can take it again.

Deactivated user​, Canvas has a guide for allowing extra attempts on a quiz here:  Once I publish my quiz, how do I use the Moderate Quiz page?

Currently, there is no way to delete an attempt, but there is a feature request currently open for voting where you can cast your vote:

Deactivated user​, there isn't a way to remove a previous quiz grade in Canvas, but there is a way to give just that student an extra attempt - Once I publish my Quiz, how can I give my students extra attempts?

Does this help?

As Mark and Kona said, you can add an extra attempt for an individual student. The student's second attempt would presumably have a better score than the first.

If however you just want to remove the points for the first quiz from the grade book, you can simply delete the grade by selecting the score and removing it.
