Here is the Certification Level Textbook which contains quizzes at the end of each chapter you can take online. We recommend completing the "Written Test" of this chapter immediately following reading this chapter. You do not turn in your end of chapter test for grading. But, you do turn in all of your 21 Handwritten Tests for grading. So, upon completion of reading this chapter, do both the end of chapter quiz and the Written Test while it is fresh on your mind. The Written Tests must be filled out by hand and completed in your own handwriting.
