When you press the ‘Start Course’ button, you will progress through the course curriculum.
Here you have an opportunity to take a ‘tour’ to help you get started.
As you move through units and quizzes, you have the opportunity to mark units and quizzes complete.
If you do this, the next time you log in, you will have access to a ‘Continue Course’ button and this will take you back to your place in the course.
If you do not mark units complete, you will go back to the beginning and the ‘Start Course’ button.
