This article explains how to save .pdf versions or print versions of your quizzes so that you can keep a copy of them, or allow students to take quizzes on paper.
To print your quiz:
Go to the quizzes tab inside a class which has had a scheduled quiz.
Click the "Print" icon next to the quiz name.
Once the quiz has opened, select File > Print.
Note: The example browser used in the screenshot is Chrome on a Macbook. Your device may look different.
From the print screen, depending on your browser, you can print the file or save to .pdf.
Once it is printed or saved to .pdf, you can then keep an archive of your quizzes or allow children to take them on paper as needed.
