For a quick overview of what you have completed in the course and how much you still have left to complete you can use your progress bar.
The progress bar shows you your progress within the course.
Green means the topic is completed
Blue means the topic is not yet completed
If you hover over the bar you can see the topic names and icons to show you if you have passed or if it is not yet completed.
You can click on a section within the progress bar to take you to that lesson or quiz. Here you can see how many attempts you have made and the grades you achieved for each attempt.
