Do I have to watch all videos in a course to take a course exam?
We believe in building up students’ prior knowledge and skills. If you feel you are prepared enough to take an exam without completing some or all video lessons in a course, you are more than welcome to give it a try. However, please remember that you must watch at least 30 minutes of the course lessons every time you wish to retake that same exam, even if you’ve passed it once and simply want to improve your score.
