Are you sure you want to go back? When you return, you will need to change your answer, and then select your final answer.

Why can’t I move on to the next exit when completing the theory work?

Did you click on the course complete button at the end of each exit once the timer has expired? If not be sure to do so otherwise the timer will reset.

Did you pass each quiz with at least an 80%? If not retake the quiz, or reread and then retake the quiz.
