Hi Carla,

We have to manually add the courses to the course selector in the Teacher Dashboard, which is why some of the courses are not currently available to add to your class. This is usually because the courses are unfinished and are still in beta mode.

Even if you're not able to add the course to your class, your students can still access the course via the direct link or through the Courses dropdown in the top left corner of the site. Additionally, you can still assign content from the course by navigating to the course directly, opening up a video or exercise, and then using the assignment bar at the top of the page.

I hope this helps! Please let me know if you have any additional questions!
