Yes, there are practice exams at the end of each course section to help prepare you for the course final exams.
You can find it before your course final exam (it will be labeled as a practice exam). Often it will be one of the final units in your course. We also recommend that you retake the unit quizzes to prepare for the finals. You can also reread any course units or sections where you experienced difficulty answering quiz questions or units where you failed the quiz. Please note that if your state requires a practice exam, you must complete this before you can move on to your final exam.
Depending on your state requirements, you will take a state and national final exam, or one course final exam. You must reach a minimum passing score on the final exams to receive a certificate of completion. This passing score varies from state to state.
