Please, can you give more insight about the school, instead of this short info "No curriculum - 80% went to college". What happens to 20%, are they completely uneducated because they didn't want to learn? Do they past some official mandatory tests? How exactly do they learn, who teaches them? You mentioned no classes if not requested, maybe 90% of knowledge gaining happens on that requested classes? How often do students get expulsion? What happens if some student don't want to do anything or don't even show up in school?
