When you add questions on the Questions page of an activity, the questions appear in separate groups, called "sections," based on their source. For example, questions you add from one folder in the Question Bank appear in a different section than questions you add from another folder. Questions you create or import appear in yet other sections.
You can add sections to an activity by selecting questions from multiple sources or by creating a new section and adding questions to it. You can then change the section order, rename the section, and set section preferences.
On the activity Questions page, click Add Sections.
Click Create New Section.
Type the name of the section and click Save. The new section and its related section information appear at the bottom of the list on the Questions page.
