Though Canvas offers the ability to curve students' grades, we recommend caution in using this feature because the grade curving cannot be undone. Pre-curving grade histories will be available, but the curving action is irreversible. It may be more tedious, but we recommend you curve grades manually at this point in time outside of Canvas. This procedure can also be performed within the New Gradebook as well.
