I have made a mistake using Curve Grades and need to undo it. Help please!

[bolandr]

I have just finished marking all my students exams in the Speedgrader.. I was trying to get the average score with mean and median (as we used to be able to do in Blackboard)- so went intuitively for "grade curver"

BIG MISTAKE!! That has now converted all the scores to a grade average and I cannot over ride it. I am getting a message telling me this cannot be undone. All my students scores are much lower than their real score and I cannot seem to undo my mistake. 

Help please! 

Thanks

 @bolandr  Welcome to the Canvas Community! As the error message and documentation state, the grade curving action cannot be undone. How do I curve grades in the Gradebook?  suggests using grade histories to retrieve pre-curve grades with the goal of re-entering them. If this isn't feasible, please send a ticket to Canvas Support to see if a support agent can assist further (How do I get help with Canvas as an instructor?).
