Undergraduate students are shipped their textbooks from MBS Direct, our online book service after tuition payment has been received. Military students who are serving overseas, who have successfully completed courses with APUS previously, will be shipped their textbook at the time of course registration, not at time of payment. The cost of textbooks for credit-seeking undergraduates is covered by the Book Grant (refer to the catalog section on the Undergraduate Book Grant for more information).

In some cases courses may use electronic course materials available in the APUS Online Library, the electronic classroom, or elsewhere as identified by the course instructor.
