1, preliminaries, the time is from April to May, and the time is different in each province. Students voluntarily participate, first in the school selection, prefecture-level cities to participate, and select students to participate in the national mathematics league.
The league is held on the first Sunday in mid-September every year. The league is divided into first instance and second instance. Among them, students who voluntarily participate in the re-examination are interested in competing for the first prize in the competition area, and students who participate in the national middle school students' mathematics winter camp (that is, the final of the mathematics competition) must participate in the preliminary examination and re-examination, and the total score of the two examinations will be used as the standard for determining the first prize in the competition area and the campers in the winter camp.
3. The final (Mathematics Winter Camp) is held every June165438+1October. The winter camp lasts five days.
