Your account allows you to track your progress.
The green horizontal line that is located on the right side of the lesson (if you are using your computer) or under the lesson (if you are using your phone), indicates your progress. This line is growing with every lessons and quiz you take.
This green line can indicate your progress only if you click on the button “Mark Complete” under the lesson you finished or “Click here to continue” after the quiz. Make sure to click one of these buttons to save your progress.
The lessons that you completed have green dots next to their titles. You can easily resume your learning any time you log in to your account. To do so click on the next lesson with a gray dot next to its name. Lessons with gray dots are the lessons that you didn’t watch yet.
To summarize, to track your progress, you need to click the “Mark completed” or “Click here to continue” button under every lesson you learned.
