Study.com - What does 'Optional' mean on quizzes?

[Supermind]

When it moves to 'optional' status it mean you have covered the material and you do not need to take it - basically it counts as a 100% score on that quiz

Actually, it is not always so. I noticed some lessons are already marked as optional, and you are awarded 5/5 points for them. But when I looked at the contents, they were very new. Of course, I had covered the basic points. But these ‘optional’ lessons were elaborating further details. I wrote to SDC asking if these optional lessons would not feature in the final test, bcos we often choose to overlook them. Haven’t heard back yet.

Thanks, I just meant that I never see it say optional until AFTER i have actually taken that particular quiz

When you are about to begin a new chapter, you will actually see a percentage score, which tells you how much has been covered in that chapter. This could mean one of two things: certain lessons are repeating from a different chapter or from a different course that you have recently completed. If you scrolled thro the list, they will all appear as ‘optional’. The other possibility is that some chapters are somehow deemed ‘optional’ even if you haven’t covered them previously. I don’t Understand what that means- if it is deemed not necessary for the final test, and if it is only for you to improve your understanding if you chose to.
