re-watch some of the videos once course is completed

Hi there! I received your request for assistance . Not only is it possible, it's highly encouraged and I applaud your willingness to both review and experiment on your own!

When I want to review a video of a course I've already taken, I generally start by clicking on the Library link at the top here and search for the course. Note that there are filters on the right side that you can use to search by topic which may make things easier depending on how many courses you've taken already. Clicking on the course will bring up the landing page for that course and if you scroll down under the "trailer" video, you'll see that the syllabus is divided into sections. These sections are then divided into "Steps". Clicking the small down arrow beside the "Steps" will show all the steps and an indication of whether they are a video, quiz, or challenge. Clicking that link will take you to the video/quiz/challenge.

If I get into a video and realize that I really need another one in that section, I navigate to it using the small white dots at the top. If you've already completed the course, they should all be checkmarks, but they are still interactive. Mousing over them will show you what the video/quiz/challenge is titled and you can then click the one you think you need.

Hope this helps!
