If you have a master course that you have been working in, make sure that it’s up-to-date with all the content you need.
If you do not have a master /sandbox then you might want to create one and copy/import content to the course from your concluded course(s). This is completely optional.
If you want to explore the different features Canvas has you can always use your Sandbox course to learn/test those features. If you create something awesome you can always copy that to your master or live course.
