The current college entrance examination scheme in Guizhou is "3+X", in which "3" means "Chinese, Mathematics and Foreign Languages" and "X" means that students choose an examination subject independently from two comprehensive subjects: liberal arts (covering politics, history and geography) and science (covering physics, chemistry and biology) according to their own wishes. This scheme is the most widely used, mature and accepted in China. The total score is 750 (language 150, mathematics 150, foreign language 150, liberal arts/science 300).
