In order to draw more learners and to demonstrate the content of your paid course, you can make any number of lessons free to access.
If you already have a paid course and you want to create some free lessons there:
- Create them
- Add them to the course
- Make it Public in the Edit mode
One of the lessons may be open to access directly from the course page. It will be available by clicking Try for free button. To make a lesson open, go to Menu - Publication and choose a free demo lesson.
