When you generate a test ID, it is automatically set to expire in seven days. If you want the test available for a longer or shorter period, you can easily set a custom expiration date.
Set Custom Expiration Date
First, tap Test ID on the top-right of the Grader; if you do not already have a one, you will need to generate a new test ID.
Next, tap on Expires to open the calendar roll.
Here, you can select a general time frame for the test ID (by hour, day, week, month, or year), or you can tap Custom Generation to set a more specific date and time of day.
When you’re done, tap Save and then tap the Test ID on the top-right corner to close the dialog box.
