Why is my course missing?

At Brilliant, we're continuously developing and refining our content to ensure we're offering the best learning experience possible. No longer seeing a course that was previously available can likely be explained by one of the following:

The course was updated, renamed, or restructured

As we further build out comprehensive coverage of various subjects, we'll occasionally rename or reorganize existing content so that it's presented to users in a more optimal sequence. Sometimes, this includes merging or separating existing courses, and as a result, it may appear that a course has disappeared.

The course was retired

To maintain exacting quality standards, we occasionally retire courses that no longer meet our threshold for content or best practices. When this occurs, these courses are moved to the "Archived" section, accessible on our desktop web platform on the Courses page.

If you're unable to locate specific content or have further questions, please reach out to our support team at support@brilliant.org.
