Simply work through the lessons one by one, selecting ‘Next lesson’ at the bottom of each page when you’re ready to move on. You need to work through every section.
When you’ve moved through all the essential lessons, your progress bar will change to 100% and you'll be able to download your course certificate from the course homepage.
You’ll see that quizzes, discussions and even some article-based lessons don’t have a completion time next to them in the ‘Outline’ tab on the course homepage. That’s because they’re optional lessons and skipping them won’t affect course completion.
But we recommend taking every lesson if you can, because the more fully you engage with the course, the more you’ll get from the experience. You can also bookmark the optional lessons and return to them later.
