Once you have purchased a course it is immediately made available in your account profile page accessible from the E-Learning menu item at the top of every page on the website. See the image below to see where to access this option.
Your Entire Learning Centre
Your account profile page (from main menu > e-Learning > account) is the centre of your learning experience. From here you can start a newly purchased course, continue an in-progress course, and even check your quiz scores.
Remember, once you have purchased a course, simply go to your profile to start learning!
