Student access to courses is removed two weeks after the end of a semester. During this process all gradebook records are deleted. You should download your gradebook to your local computer after you submit your final grades.
Follow these steps to do it.
In order to export the gradebook for a course, you should goto the [Control Panel] for that course and click on the [Grade Center] link. Inside the Grade Center you should point to the [Manage] button on the menu bar and then click on the [Download] link. Under [Data] section, select the [Full Grade Center] option, under the [Options] section, select [Tab] as the delimiter type and [Yes] to include hidden information and then click on the [Submit] button at the bottom of the page. On the next page click on the [Download] button. You should get a dialog box with a request to save the file. Save the file to a location where you can find it later. The file you saved can be opened with Microsoft Excel.
