In stead of building something custom, I want to see if there ever was such a solution created to our problem.
We are creating an online language school for a client in Brazil. He wants to have some courses made free to everyone, but some courses must be payed for before use. This is quite straight forward.
The problem is, the free courses should only be *partially* free. That is, if a student enrolls to the course, he will only have access to some of the content/assessments. Only after payment has been made, the rest of the course will become available. Either non-payed for content/assessments will be blocked, or all content/assessments will be available, but only the feedback will be blocked until payment is made.
The whole idea behind it is to allow some sort of trial access to the school, and if the student wants to go further with his/her studies and make it official, he can simply pay, and continue where he/she left off.
I am completely new to moodle, so please bear with me if I'm unclear.
Thanks!
