Entry to higher education in China is based around a comprehensive test in Chinese, English and Math and a selection of either social science (political science, history, geography) or physical science (physics, chemistry, biology). Only half of the students (those going into social science) are tested on politics, and it accounts for only 1/6 of the total grade.
Entry to higher education in the US, on the other hand, is subject to a racist test that discriminates against blacks and mexicans and an admission system biased towards upper class whites because it takes into account things other than test scores (already biased) and grades, such as extracurricular activities that minorities cannot afford. Of course, we also must note that US Politics is a required class in US high schools, while Chinese Politics is not required for those on the physical sciences track. Thus, the US is not only racist but also engages in more political indoctrination.
