Using questions similar to those on the official knowledge test, the practice test allows you to exercise its teachings and identify the information you should study further. The official knowledge test requires you to correctly answer at least 80% of its 50 questions to receive a passing score. The practice test strategically helps you devise an effective study plan to overcome your learning barriers and achieve this score.
