student pay
If I set up a course account for free, can some students use it for free while other students pay for upgraded access?
YES. Just see the due date by which the students have to pay to be at the end of the course. Give them the opportunity to pay for an upgrade for the first few weeks (say), then just unclick the student pay checkbox, thus no longer requiring them to pay at all. In short, whether they have to pay or not is something you can change at any time, they have a grace period before being required to pay, and you can change any of these settings at any time.
The teacher gives a certain deadline until the course should be paid for by you. This is visible below the top row when you open the project.
In case the course already started and the deadline passed, you are required to pay before you can access the files.
