All ChemEd X content is free.
ChemEd X no longer includes "premium" content and so no longer supports subscriptions.
Previously, ChemEd X premium content, such as our video library and online instructional materials (ChemEd X Web Software), required a subscription for access. No longer. Enjoy!
With our recent move to a new platform, you may still find links that denote "Subscriber only" content. Ignore the label and continue to access such content.
