Speaking of systemic teaching issues, the only thing worse than math is physics.
I was able to do calculus at 10 yrs old (the reason I know that is kind of a long story), yet even at 20 years old I struggled to understand how it was taught.
Physics is worse because everything is always taught as an aprocryphal story about who discovered it and how. And then hand-waved away with math whenever questions arise.
Right, so send them to public school where individuality is homogenized out of them.
