Your understanding of appropriate safety measures, emergency procedures, and other crucial information will form the foundation of your success. You must correctly answer at least 80% of the 20 questions on the official knowledge test to pass. Using questions resembling those on the official knowledge test, the practice test delivers outstanding results.
