> we'll have to cut down on something in the high school curriculum. It's a trade-off between breadth and depth. Teaching increases depth and internalization, but it also can't be done when there's too many subject to cover. When I was growing up, high school students took 9 subjects on average. In contrast, a high school teacher only teaches 1-4 subjects.
