CMV: “Useless” higher level math classes (calc, trig, etc.) should not be required for HS graduation. Not only will most people never use that math outside of school, but the extremely small minority who WILL actually use it will just end up retaking those exact same classes in college anyway.

CMV："无用的 "高级数学课（计算、三角函数等）不应该是高中毕业的必要条件。不仅大多数人在校外不会用到这些数学，而且极少数真正会用到的人最终也会在大学里重修这些相同的课程。
