I'm just getting started and so I can't afford to upgrade to a paid version yet. Until then, is there a way to use pricing tiers of some sort with the free version?
I'm not sure what you mean by pricing tiers. Do you mind providing a bit more info and I can point you in the right direction.
On the Starter plan, what you can do is duplicate the course and simply set a different price for each one. Students can then chose the course which fits their needs.
Hope this helps!
