To access written materials for a course, press the "Written Materials" tab on the left of the video player in the course center.  The course center is what pop-ups when you're watching one of the online video courses.  

All of our courses come with written materials available in pdf format.  You can print this pdf, save it onto your computer, or even access it at a later time.   You will still have access to the written materials (as well as the course itself) after you have completed the course.
