There are 3 elective courses in science, including 2- 1, 2-2 and 2-2.
The above are the textbooks for the math exam (150).
If you want to take a test, you have to take a comprehensive ability test.
Mathematics is two problems, one is elective course 4-5 (selected lectures on inequality), and the other is elective course 4-4 (coordinate system and parameter equation).
Take it.
