To create and edit tests and quizzes you need Question Tools Editor. QT Editor is visual — just draw your screen and question! Simply add text areas, pictures, shapes, multiple-choice buttons, audio clips, video, true/false buttons, hotspots, text answers, menus, and drag them to where you want them to be. You can set simple or complex marking, set time limits, and even allow your users to try difficult questions again.
The App Store version of Question Tools Editor lacks the video and audio capabilities.
