You can complete many course lessons by simply marking the lesson complete by clicking on the button below the video. Some courses require that you watch the entire video before you can complete the lesson. The 8 hour and 4 hour family guardian courses are examples of courses that require playing of the entire video lesson before you can mark it complete and move to the next lesson. In addition, several lesson modules in these courses require that you successfully complete a quiz. If you fail the quiz, you should review the answers which are provided as part of the grading. This will enable you to answer the questions correctly when you take the quiz the second time. There is no need to repeatedly take the quiz, so look for the answers provided after the first quiz attempt.
