The methods to creat a course are different as a product or as a course. If making as a course, it do now show the price, but other factors is more details...
So should I create a course with both or one of both ? or How to use both for making a course
If you want to sell the course, you'll have to create both. A course can only be sold when a product which is connected to the course is sold.
okay.. that is inconvenient to us.. I found "wplms woocommerce" while searching for the solution, and get to know the plugin has role to connect both.
in that case, it is no problem just to create product without making a coure?
If you are creating the course from the back end then you have to create a product first and then while creating /editing the course you need to include it in the course and then again you have to include/connect the course in product edit page settings area in backend .
However if you create course from front end then you will have both of the options at one place under pricing section of FEE .
