Hi kperkins1017!
KendraB is correct; all of the books and course materials, including ICD9 & 10 are included in the cost of the program. Your classes are intended to be taken one at a time, because they're designed to build on one another. As you complete the required number of lessons in a particular class, it acts like a trigger to open up the next class. If there is a physical textbook in that next class, it would ship at that time.
Book Shipments FAQ& Tracking Shipments are 2 documents that may come in handy moving forward.
Let me know if I can be of assistance in the future!
