Restore a Saved Version of Your Gradebook
In those cases when your gradebook has been significantly altered, backing up to a previously saved version of your gradebook may be the best option. Use the Restore Saved Grades option from the Gradebook Tools menu.
Even if you do restore to an earlier version, you can still restore back to a more recent version.
Note: DO NOT use this feature to restore a gradebook you've accidentally deleted. The restore grades tool is for use with an existing gradebook. To restore a gradebook, simply re-create the gradebook with the appropriate date range. Follow our online directions for adding a gradebook.
