We want to give you a quick reminder about the layout of this course. Like all of our CE courses, we use quizzes to help you learn. These quizzes may come before or after a lesson or a topic. This is how we teach the material to enhance your learning experience. You do not have to pass a quiz to proceed to the next lesson. There is an audio explaination after each quiz question that explains the concept we are teaching. The only test you do have to pass to earn your certificate is at the end of the course. So, sit back, relax, and have fun! Listen to the audio, then click on the opening quiz below to begin!
