On: America's High School Graduates Look Like Other Countries' High School Dropouts

It should not be judged so easily.

However I have to say when I was in MBA course in US, I don't know why the teacher needs to teach the students how to calculate a linear equations of two unknowns. In China that is a question in elementary school and less than grade 5. I wonder how they graduated from high school and learning business.

Virtually everyone in your class learned to solve systems of equations in middle school or high school, and again in college math.

The reason the teacher explained it is that for many students in an MBA program it has been many years since they had to use that particular skill.

Linear equations of two unknowns are taught at grade 7 or 8, not less than 5 in China. Although still significant younger than MBAs.
