Still seeing courses, levels, and lessons? We're updating names across Brilliant: courses are now topics, levels are units, and lessons are concepts. Your progress and content stay the same.
At Brilliant, we're continuously developing and refining our content to ensure we're offering the best learning experience possible. No longer seeing a topic that was previously available can likely be explained by one of the following:
The topic 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 topics, and as a result, it may appear that a topic has disappeared.
The topic was retired
To maintain exacting quality standards, we occasionally retire topics that no longer meet our threshold for content or best practices. When this occurs, these topics are moved to the "Archived" section, accessible on our desktop web platform on the Topics (or 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.
