Why do so many people recommend khan academy when it's compliant with common core math and worse online? Online educational sources has made everyone more retarded since it's creation. Go look at where the children of the elite go to school now and then compare it to the current public education system. The rich banned their kids from the internet and buy them books and toys instead. The rich themselves don't even go on social media. Those fuckers made screen free education and socializing into a luxury.
