If you see this icon in the margin of your ebook, your teacher has added an assessment to your text.
Click on the icon to open and answer the assessment. Your teacher will be able to see and score your response.
If you are reading in our web reader, you can find a list of all the assessments in your ebook by clicking the Overlay icon on the left side of the web reader screen.
You can also find a list of all assessment questions (including those published by your teacher in other ebooks and those that are not associated with a particular line of text) by going to the course dashboard (My Courses -> click your course icon) on the web portal (not the mobile apps) and clicking Assessments on the left side of the page. You'll be able to answer assessments there, as well.
