Jiangsu province regards the elective part of high school mathematics as an additional question (not required by liberal arts), which is very simple. 40 points and 30 points are sub-topics, 5 points are slightly more difficult, and 5 points are slightly more difficult.

Because of the elective part, you don't have to study in high school. It is only stipulated that some chapters can be selected from them, and schools can choose their own elective chapters. Therefore, the additional questions of the college entrance examination are also for students to decide which one to choose (each question has several questions, and the candidates choose one).
