The article's comparison to the SAT is misleading. Whereas the SAT is a reasoning test, the Gao Kao is a series of subject tests (think SAT Subject Tests or AP exams). The three mandatory subjects are Mathematics, Chinese, and a foreign language. In addition, students select one to three additional exams, and this choice depends on what they hope to study in college. Prospective science/engineering students will choose from Biology, Chemistry, and Physics; prospective arts/humanities students will choose from History, Geography, and Political Education.
