You can see all the lessons for a course on the left side panel. You can click on these to navigate to them if the course allows you to. Sometimes the course will require you to finish the lessons sequentially.

Sometimes a lesson will have a quiz, you can either navigate to the quiz by clicking on it on the left side or the quiz will be at the bottom of the lessons that it’s meant to be a part of. 

These quizzes will be utilized to take notes for specific activities!
