If you don’t want to be in class, fine. Don’t.
Correct.
Attempts to force a traditional post-elementary education on a low-IQ high impulsivity population are first of all doomed to fail and second of all will require increasing levels of coercion, especially of males, as their age increases.
The obvious answer to preserve some semblance of education after eighth grade is entrance exams for free high school - if your IQ is too low or you don't want to go, that's fine.
High school isn't prison, it's time to stop running it like one.
