New Users: Click the "Practice Proficiency Exam" button on the left to log-in to the system and take the exam. The system will analyze your answers and generate a list of areas where you need help. Each of these areas will guide you through the concepts and enable you to practice what you've learned. When you're ready, you will take a final challenge to "test-out" of the tutorial. You will need to have your speakers turned on or have headphones to hear the audio in the tutorial modules!
