Well done for completing your course! The course completion icon shows how much of the course you have viewed. It includes every element within the course, including optional resources and quizzes. If you did not look at all of the optional elements, the icon will show less than 100% even when you have completed the course. Don’t worry! This does not affect your final assessment or your certificate in any way. However, you might want to go back and look at the optional resources, to ensure you’ve not missed out on anything that you’d find useful.
