It is held on the first Sunday in mid-September every year, with 20 18 slightly ahead of schedule and in September 10. The league is divided into one test and two tests (also called extra test). Students who participate in the National Senior High School Mathematics League can voluntarily choose whether to participate in the "National Senior High School Mathematics League Extra Test"; Students who intend to win the first prize in the competition area and participate in the national winter camp for middle school students must participate in the initial test and the second test (additional test). The total score of the two tests will be used as the standard for determining the first prize in the competition area and the winter campers.

(Trial): The scope of knowledge involved does not exceed the teaching requirements and contents stipulated in the Mathematics Syllabus for Full-time Ordinary Senior Middle Schools in 2000 by the Ministry of Education, but the requirements for methods have been improved.

(ii) Contact with the International Mathematical Olympiad to expand knowledge; Some contents outside the outline have been appropriately added.

The expanded data structure, question type and score collocation are as follows:

The initial test time is 8:00-9:20 * * 80 minutes, including 8 fill-in-the-blank questions (8 points for each question) and 3 solution questions (16 points, 20 points and 20 points respectively), and the full score is 120 points.

The time of the second exam is 9: 40- 12: 10, *** 150 minutes, including four solutions, involving plane geometry, algebra, number theory and combination. 40 points for the first two questions, 50 points for the last two questions, out of 180. In some areas, the initial examination and the second examination are conducted together. The following are some questions and reference answers of 20 18 senior high school mathematics volume a.

The league is the provincial semi-final stage of the mathematics competition (the previous stage is the preliminaries), which will produce the first, second and third prizes in the provincial division, and the winners of each province are expected to be announced in late September.
