The advantage of duplicating a course is that it saves time by re-using an already created chapter structure. All you have to do is modify the content of each chapter.
In the “Training” menu, you can consult the list of all the training courses created. Several links are available in front of each training title, on the right of the concerned line, including the link “Duplicate”.
A window will appear asking you to give a title to the duplicated course.
