The Content tab works a lot like Google Classroom. You can organize materials into Sections — drag to reorder them however makes sense for your course — and add resources to each one.

Click the “+” menu inside a section to add a resource. You've got ten types to choose from:

Folder, Video, Files, Discussion, Test, Polls, Assessment, YouTube, Link, Embed Link, and Copy Resource (which lets you reuse a resource you've already built elsewhere rather than recreating it).

This is the natural place to post homework, quizzes, reading material, or anything else you want students to access outside of a live session.

Each resource can also be marked complete using the Mark as complete option. Tutors and admins can use this to track which pieces of content have been finished and which are still pending — and it gives students the same visibility, so they can see their own progress through the course content at a glance.
