I watched the videos but when it came to the challenges it went to the next video. I need to do the challenges for my HTML5 class. Please explain how to get to the challenges after the video if they don't automatically play. Thank you very much.
Sounds like you might be seeing the videos page for this course?
To access the challenges, you'll need to play through the course on our course platform.
As an example, here is the link for the first challenge in Level 2:
