Why do I see a lesson from a Tier I did not enroll in?

For some courses that have multiple tiers, you may see the titles and links for content only avaible to a higher tier. If you try to open these pages you will get a message that will prompt you to upgrade to the tier required to access the content. You can either skip over this content by clicking the next link in the course lesson table or by clicking “Next Lesson” at the bottom of the lesson page.
