In my half-asleep state, I accidentally made a batch grade change to an entire assignment. (I meant to fill in zeros for those who did not submit work, but I failed to realize that, since the others hadn't been graded yet, that this would change ALL 90 students' grades to 0.) Is there a plan to create an un-do option in the gradebook for such mistakes?
I'm sorry that happened to you, and an undo option would be nice! Until then, you can use the Gradebook History feature to at least see the grades that were changed.
How do I view the history of all grading changes in the Gradebook?
