Intuitively though at 40ish, most of the things I "learned" in school but never used have all fallen out of my head. The knowledge I have is things that I was actually excited to learn: computers, enough math to make computers do what I wanted, writing so I could socialize with other nerds better, history because I like history. Basically, you couldn't stop me from learning those things, but the things I was forced to learn ended up being somewhat of a waste of time for both me and the instructor, I think. I mean, you want to challenge kids a bit because they might resist something at first and then eventually realize they like it quite a bit (math for instance), but there's also a point where the tests mostly just become kayfabe. We say these people are doing "better" because they get a higher test score, but then they get into the real world where there is no test score, and that entire academic framework is kind of useless and maybe even harmful.
