First, the second year of high school will take the county-level preliminary examination in March or April next semester and register at the school. The school will mobilize (some students in Grade One will participate in the competition with Grade Two), and each county will have a certain number of places (in fact, each local education unit is a competition area). Students who pass the preliminary test will take part in provincial competitions in the summer vacation of senior two-first go to a university to attend a summer camp for about ten days. Every morning and afternoon, a famous teacher or university professor will be invited to talk about the Olympic Games. On the last day of the summer camp, there are two papers, each with a score of 150, which seems to be two hours or 1.5 hours, with a break. The first paper has some fill-in-the-blank questions or multiple-choice questions, and there are several big questions; The second paper has three major topics: geometry, number theory, one forgotten; After the game in the morning, I asked the teacher to give a lesson on Olympic Mathematics in the afternoon, and few people attended the class. Then go home and wait until the third year of high school starts to know the result of the game. Those who were promoted participated in the second interview in the province, and the top ones were walked to Tsinghua Peking University Fudan University and other famous schools. They will also choose a few people to participate in the national training team, take the national training team exam every day, and finally participate in the international Olympic Games. In recent years, China has been the first in the total score.
