To temporarily suspend the delivery of questions in a Qstream (but remain enrolled and save your current progress), you can activate Vacation Hold.
To do this, log into your Qstream account and click on the Qstream name under the Qstreams you are taking section.
On that screen, select the Qstream Options tab.
In the Vacation Hold section at the bottom...
Enter the date you want to stop question delivery or click the calendar icon and select the date there.
Enter the number of days you want the vacation hold to last.
Your Vacation Hold will begin on the date you have specified. You can cancel it at any time by clicking the End Vacation Hold link on your Qstream Dashboard.
