Lectures will be automatically marked as complete once you have watched every minute of the lecture, but, if you need to manually mark the lecture as complete, you can easily do so.
To learn how to mark or unmark a lecture as complete, please read below.
Lectures Marked as Complete
Lectures that have been completed will have a checkmark to the right of it on the course dashboard, or the curriculum navigation in the video player. If the circle is blank, however, then the lecture is not marked as complete.
