Annotations API Features Overview

The students can use the sticky note on the page as a location-centric reminder for them to execute another task and return.

End users can open this tool and type any information they want into the Notepad window. They may be gathering their thoughts, composing a draft, or making a list of things to do, all within the assessment.

The context of the notepad extends across multiple items, and is more readily available throughout the assessment compared to sticky notes, which only appear when their parent Question or Item is visible on the page.

End users can select this tool and then perform freehand drawing on top of the page. They can use this to draw attention to certain areas, visually mark a boundary, or indicate things to be removed.
