Hello there ericray1979!
It sounds like you are wondering where your physical textbook may be? If so, this may help!
Textbooks take about 10 business days to arrive in the mail. You can check the shipment of your textbooks by selecting the "View Shipment History" button inside of the "What would you like to do" box on the right-hand side of your "My Courses Page".
Keep in mind not all courses have physical textbooks. If they do make sure to utilize the Textbook and the Study guide. Other wise you can just use the Online Textbook.
Another thing to keep in mind is the, usually, inside the header of the Course box will be a bullet that say something along the lines of "Number of lessons completed before next Shipment: (# of lessons)". This will appear if your next course has a physical textbook that needs sent to you.
I hope that this helps!
