Summer School Requirements (Patreon)

As I will be taking a more hands-on approach to grading and interaction with the summer school classes over the next few weeks, I'd like to establish some requirements. My main criteria is... I want people who will have fun, interact with each other, and be creative and engaging. Easy right?

It would also be nice if they've already taken 'Punishment Positions' as that allows me to use some of the stuff from that in the lessons without context (the second brain, the memory aid, etc). Additionally, having completed that class demonstrates their interest in the concept.

So, all of that being said, what should be the requirement for enrolling in a summer school class? Is it JUST having completed the Punishment Position class? Should I charge 'slut tokens' for it? Make everyone pass a quiz? What's fun but also achieves the desired goal? Any thoughts, my oh-so-lovely schoolgirl patrons?
