I entered the grades of a quiz on canvas. after few days I tried to view the class quiz record, but I was unable to view the last entered grades. The entire column is missing.
Hi Taha Mubarak Welcome to the Canvas Community, and sorry to see that your question has been here for a few days or so. Actually, perhaps it's been resolved by now, but if something has disappeared as a column in your Gradebook that means that the entire assignment has been deleted. You did not state if this was an online quiz or a quiz administered on paper, but the bottom line is to first check where the quiz was posted (be it in Quizzes or Assignments ). My hunch is that it is missing altogether.
If so, you will want to use the nifty "undelete" trick that is largely undocumented. You can read about here: Undelete . It will not work 100% of the time, but I have generally found it to be successful with my own faculty on assignments and quizzes. (NOT Discussions, I might add, should you ever run into that.) I've had many faculty wonder how on earth anything got deleted, but rather than rounding up suspects or figuring out how it happened, just be thankful that it works most of the time! Best of all, undelete WILL restore all grades.
If something else happened (and again, if an entire column is missing it's hard to say what that "something" could be!), you can try checking the history of your grades. This will be especially useful if you have found the column again but all grades are missing. This feature is outlined here: How do I view the history of all grading changes in the Gradebook?
If neither of the above works, it is time to contact Canvas Support directly (Help>>Report a Problem). They can do miracles on their end.
I hope this helps, Taha!
