I am a student of this school. No, don’t ask for an ID card. No cards are necessary in this school. We enroll ourselves, and if we flunk, that’s on us.
How do you flunk? You fail to learn the lesson. What about the exam, you ask? That doesn’t matter. Almost everyone fails that at one point or another. It’s the lesson after that counts.
And there are no grades, except what you give yourself.
