View Assessment Item History
When you save an assessment item, either in draft mode or as Final, MATLAB® Grader™ saves a copy.
To view the assessment item history, select Actions > View Version History.
By default, MATLAB Grader displays only the versions saved as Final. To view assessment item drafts also, check Include draft versions.
To view a particular version, click the date and time link.
When you are viewing a particular version, you can navigate forward and backward through older and more recent versions using the navigation arrows.
Restoring an older version is not currently possible. To use the content of an older version, copy and paste the older content into the current version.
