It doesn't make sense to me that all kids get the same education at the same pace even though they have different abilities. If someone learns slower, maybe they need more hours at school to learn the same material as someone who learns faster. And maybe they even need to skip some unimportant subjects to find that time. It would be great if every individual student somehow got a tailored program (impractical with conventional teaching, I know) so they could all reach a sufficient standard of education. Some geniuses might not even have to go to school if they can just flip through the book and ace the test on their own, while the labor saved teaching them could be spent on those who need more.
