the thing about schools is that schools aren't there for learning
how it goes on: you get an assignment, you complete an assignment, and then you get graded
getting graded efficiently destroys the very foundation of studying and learning: fucking up, and fucking up royally at times
a bad grade is a punishment by itself, and depending on a kid's luck or lack of it, this punishment has further punishments attached to it, be so "no sweets for you" or getting beaten up to the point of getting into a hospital
therefore a child has no real reason for learning, only for memorising stuff for enough time to write a test and forget it forever if diligent, or just not giving a shit if normal or troubled
again, a student can also be diligent but not neurotypical enough to just memorize shit without attaching any meaning to it, resulting in a diligent student with bad grades
and this is the rotten system that makes the foundation of pretty much everything
