Many online classes have a course-specific orientation, which explains how that particular class works.
For many online classes, orientation is incorporated into the course as a video for you to watch or a module for you to work through. Simply log in to Canvas on the class start date, and access the course to learn more.
Some online classes may require you to attend a synchronous, online orientation meeting at a specific day and time. Log in to Canvas on the class start date, and access the course to find out specific details.
