(zero) The 2024 International Olympiad in Five Disciplines will be held in the following times and locations: International Mathematical Olympiad (IMO): The 65th IMO will be held in Bath, United Kingdom, from July 11 to 22, 2024International Physics Olympiad (IPhO) : The 54th IPhO will be held in Iran from July 21 to 29, 2024International Chemistry Olympiad (IChO) : The 56th IChO will be held in Saudi Arabia from July 21 to 31, 2024International Olympiad in Informatics (IOI) : The 36th IOI will be held in Egypt from September 1 to 8, 2024International Biology Olympiad (IBO) : The 35th IBO was held in Kazakhstan from July 7 to 14, 2024.
On July 14, 2024, the 35th International Biology Olympiad (IBO) closed in Kazakhstan. All four members of the Chinese team won gold medals, and the final rankings were 1st, 2nd, 5th, and 7th, setting the best results in history in the past ten years.
(1) On July 21, 2024, the 65th IMO International Mathematical Olympiad was successfully concluded in Bath, United Kingdom. In terms of team results, the Chinese team scored a total of 190 points, with a difference of 2 points, ending the "five consecutive championships" and winning the second place in the team. United States finished first in the team (192 points) and Korea finished third in the team (168 points).
In terms of individual results, Shi Haojia from Hailiang Senior High School in Zhuji City, Zhejiang Province, the only one in the field scored 42 points. Second place with a total of 40 points was Ivan Chasovskikh from Russia. Third place went to Alexander Wang from Team United States, who scored 38 points. Last year, too, he scored 41 points, sixth overall.
This IMO is a history-making one.
According to the statistics on the official website, a total of 108 countries (or regions) participated in this competition, with a total of 609 players, including 528 male players and 81 female players. The number of female players accounted for 81/609≈13.3%. As in previous years, this year's IMO has a total of six questions, each with a maximum score of 7 points, and a total score of 42 points. And this year's gold, silver and bronze medal lines have dropped a lot compared with last year. This year's gold line is 29 points, the silver line is 22 points, and the bronze line is 16 points. The contestants won: 54 gold medals, accounting for 54/609 = 8.87%; 121 silver medals, accounting for 121/609 = 19.87%; 145 bronze medals, accounting for = 23.81%; The total winning rate is (54 + 121 + 145) / 609 = 52.55%, which is almost half the percentage. 170 were honorably nominated, and another 119 were unfortunately not awarded or nominated. Compared with the International Olympiad in Informatics, a total of 360 official contestants participated in the IOI2023, and finally 30 gold medals, 58 silver medals, and 90 bronze medals were finally produced, and the winning rate was about 50%, which is similar to the International Mathematical Olympiad. After 2 days of hard work, the IMO2024 team TOP10 results are as follows: [1] United States (5 golds and 1 silver) [2] China (5 golds and 1 silver) [3] Korea (2 golds and 4 silvers) [4] India (4 golds, 1 silver and 1 honor) [5] Belarus (4 golds and 2 bronzes) [6] Singapore (1 gold and 5 silver)
[6] United Kingdom (2 gold, 3 silver and 1 bronze) [8] Hungary (2 gold, 3 silver and 1 bronze) [9] Poland (1 gold, 4 silver and 1 bronze) [9] Turkey (2 gold, 2 silver and 2 bronze)
Russia's players continued to participate in their individual capacity this year, with six players scoring a total of 185 points, followed by China and ahead of Korea.
It is worth mentioning that many national (or regional) groups have made history this time. India has advanced from 9th place last year to 4th place this year; Belarus rushed from 17th to 5th; Bosnia and Herzegovina also rushed from 36th to 13th, all of which were the best in history. In addition, Singapore has returned to the top 10 in five years, United Kingdom has also returned to the top 10 in three years, and Hungary has returned to the top 10 for the first time in 20 years.

Among the six players in the Chinese team, Shi Haojia and Wang Chunji both got full marks last year, and this is the second time they have participated in the International Mathematical Olympiad.
Shi Haojia has won full marks for two consecutive years, and his strength is super strong. Not only that, but he is also the fourth IMO double perfect score (full score for two consecutive years) player in the history of the Chinese team after Luo Wei, Fu Yunhao, and Wei Dongyi.
Xu Qiming, a student from Wuhan Jingkai Foreign Chinese Senior High School, won the gold medal with a score of 35 points.
Deng Zhewen from Wuchang Experimental Middle School won the gold medal with a score of 30 points. Deng and Xu are both from Hubei Province, which shows the strength of Hubei Province's Olympiad mathematics.
Hexagonal schools have students selected for the national team in this year's five major science Olympiads in the High School Affiliated to the National People's Congress. This year, two players from the High School Affiliated to the National People's Congress were selected for the national team of the Mathematics Olympiad. Wang Yubang won the gold medal with a score of 30 points, and Ye Yuxing won the silver medal with a score of 23 points.
This year's six national team players are from Shanghai, Hubei, Beijing and Zhejiang, which are the first echelon provinces in the domestic Mathematics Olympiad.
It is worth mentioning that the number of participants in this year's 81 female contestants has reached the highest number in history!
Team United States' Jessica Wan is the first female player on the United States national team since 2007. She is from Florida Virtual School and has won four consecutive EGMO gold medals (European Women's Olympiad) from 2021 to 2024.

Canada also welcomed Emily Ma, the first female player since 2017, who won a silver medal in the European Mathematical Olympiad sister tournament EGMO 2024.
Particularly dazzling is the Australia team, with a total of four female players, which is also the first time in Australia's history. Among them, Cloris Xu and Iris Xu are twin sisters, who won consecutive EGMO gold medals from 2022 to 2024, and this year is also the second time they have been selected for the Australia national team.

Let's talk about the Asian players that everyone talks about, and more specifically, the proportion or number of Chinese players. Among the top 10 groups, Asian countries account for half, European countries occupy 4 seats, and the remaining one is the United States. Five members of the United States team are Asian, and the United Kingdom team also has Alex Chui (individual No. 5) and Haolin Zhao. In addition, some popular study abroad destination countries have many Asian faces in the team. The Canada team is full of Chinese faces, and Warren Bei, a Year 10 student this year, has even joined the team for the fourth consecutive year. There are also many Chinese faces in the Australia and New Zealand teams. According to incomplete statistics, there are Chinese children in Switzerland, Sweden, Finland, Austria, Ireland, Portugal and other teams.
Not only are there many Chinese faces in the Mathematics Olympiad, but there are also many Chinese faces in other subjects such as the Informatics Olympiad. For example, among the four players on the IOI2023 United States team, two are Chinese faces; Among the four players of the European Women's Informatics Olympiad GEOI United States team, some of them are Chinese faces.

A reporter from the Hangzhou media "Metropolis Express" once sorted out the process with the selection of Zhejiang Province: first, more than 5,000 people participated in the provincial preliminaries, and about 1,500 people were selected to participate in the league, of which only 35-40 people could enter the Zhejiang provincial team. After that, the national finals, the top 60 entered the national training team, and last year, about 10 people from Zhejiang entered. In the training team, two rounds of examinations of "60 into 15" and "15 into 6" were conducted, and 6 people were finally selected to form the national team. Specifically, the whole process of the Mathematical Olympiad is divided into five stages: preliminaries, leagues, national finals (winter camp), national team selection, and the International Mathematical Olympiad IMO. 1. Preliminaries(1) Each province and municipality organizes itself; (2) The time is generally 5~6 months; (3) Written test for high school students; (4) Unified enrollment of schools; (5) The purpose is to screen out the contestants who will participate in the National High School Mathematics League, and for provinces and cities that do not have preliminaries, the quota allocation system will be adopted. 2. Mathematics League (1) Sponsored by the Chinese Mathematical Society; (2) The second Sunday of September; (3) For high school students who have won the ranking in the preliminary round; (4) Unified registration and written examination of the school; (5) The league is divided into one test and two trials, and the test is taken in the same place on the same day, with a 20 or 30-minute break in between. (6) Candidates who participate in the winter camp will be screened out, and the awards will be provincial 1, provincial 2, and provincial 3; The top students in the first province form a provincial team to participate in the CMO;
(7) The quota of provincial 1/provincial team will be uniformly allocated by the Mathematical Society. 3. National Middle School Mathematics Competition Finals (Winter Camp) (1) Sponsored by the Chinese Mathematical Society; (2) The contest will be held in November; (3) The participants are the top students in the Chinese Women's Mathematics Olympiad (the top 16 in 2023) from all provincial, municipal and provincial teams + the top students in the Chinese Women's Mathematics Olympiad. (4) The awards are the national first, second and third prizes, that is, gold, silver and bronze medals, and the top 60 players with gold medals will be selected into the national training team of the year, and the members of the training team have the qualifications to be sent to Tsinghua University, Peking University and other famous universities. (5) The Winter Camp (CMO) is the highest, largest and most influential mathematics competition for middle school students in mainland China. 4. National Team Selection (1) The 60 students selected for the national training team will conduct two rounds of training and competition, and determine the final national team members. (2) The first phase is usually held in early March of the following year, and 15 team members are selected to enter the second phase of the training camp; (3) The second phase is usually held in late March of the following year, and finally 6 team members will be selected to form a national team to represent China in the International Mathematical Olympiad. 5. IMO(1) IMO is the abbreviation of the International Mathematical Olympiad Mathematical Competition; (2) Hosted by each participating country in turn; (3) The competition time is July of the following year; (4) The participants are 6 contestants + 2 team leaders (students must be under 20 years old and have the highest secondary education); (5) The examination format is a written test;
(6) Awards are divided into gold, silver and bronze medals; It can be seen from the above competition process that if a single-digit student wants to enter the IMO Chinese national team, he must at least go through the preliminaries, league, winter camp (finals) and two rounds of national training team selection, which is really equivalent to "passing five levels and cutting six generals" in order to stand out among tens of thousands of people, and the difficulty can be imagined!
