I am a freshman in Grade Three of Beijing Liberal Arts (1~ I became Grade Three in September), and my math class ended in the first half of the second semester of Grade Two. The teaching sequence of liberal arts mathematics in senior high schools in Beijing is as follows:

Required part: 1. Compulsory one (mainly set and function); 2. Compulsory 4 (mainly trigonometric function); 3. Compulsory five (the main content is series); 4. Compulsory course 2 (mainly geometry); 5. Compulsory three (mainly algorithm, the teacher basically passed by).

Elective part (only the compulsory modules are listed after the compulsory courses, which are within the scope of the college entrance examination): 6. Elective course1-1; 7. Elective course 1-2. The elective part is not very solid, with derivatives and so on. . .

Some schools will add elective course 4- 1. It is about the knowledge expansion of geometry. Our teacher bought a book, but stopped talking. . . The college entrance examination will not be tested, but it is helpful for training thinking.

The above textbooks are all people's education editions. Teach version a and version b respectively. Different districts have different choices, but the knowledge points of textbooks are the same. The college entrance examination only examines the overlapping parts of textbooks, so don't worry about different versions. Senior two should start from compulsory three, and start the first round of review after class.
