I am in starkest disagreement with this claim from the top-level comment: > I think that a lot of students don't have what it takes to learn the mathematics curriculum they signed up for, no matter how you teach them. Unless “a lot of students” means “the < 10% of the population with a severe mental handicap most of whom never went to college”... which okay, I am happy to concede that. I also dispute that with all else held equal, certain people are inherently “10 times faster” at “improving” at mathematics. This just doesn’t seem plausible to me. For context, I have observed close-up several of the smartest math students in the world, and also spent a decent amount of time trying to help people who were heavily struggling with remedial coursework. I would even claim that the latter group were “improving faster” than the former group.
