These home-study courses are available either in the book format or, in many cases, in the online format. In the book format, we'll send you the course text, post-test, and a Scantron card. You'll read the book, answer the questions, and return the Scantron card to us. Passing grade is 70%. Then, you'll get your Certificate of Completion. In the online format, you'll read the book online and take the post-test online at the end of which you'll know your score. We'll send you your Certificate of Completion in the mail.
