Yes, all courses can be taken at your leisure, from any location at anytime. Once a course is started, you can pause and come back to it at anytime. Even when the course is complete, you can revisit any lesson by dropping in at any point in the course. Our e-learning system automatically records which lessons you have completed, and what stage you are currently at in each course you are subscribed to.
There is no need to save your work manually, as your progress is automatically recorded during each visit you make to your course.
All of this is accessible through your account profile where you will find all of your courses, with links to every lesson it contains.
