Some exams may allow you to flag items that you want to return to later. Review of items must be done during the testing time. You can select items for review whether you have answered them or not.
To flag an item for review:
A flag image appears within the flag outline when the item has been flagged for review. If you wish to unflag the item, click the Flag for Review button again and the flag image disappears.
When you reach the last item in a section, press the Next button to move to the Review Screen.
