After taking a quiz in Canvas, I had students that did poorly complete a reteaching module that ended with a re-quiz. I want the re-quiz to replace their original quiz grade- but only for the students that took the re-quiz. Right now Canvas is counting both scores. Other than deleting their first quiz grade altogether (which I would like to keep for information) is there a way to have Canvas not count a single quiz grade for a particular student? Any ideas would be appreciated.
