The International Mathematics Olympiad is held over two days, from 9:10 a.m. to 12:40 p.m., a total of three and a half hours.

There are 3 questions in each test, and the answer sheet will be judged by the national team leader according to the reference answers and scoring criteria, and then negotiate with the coordinator designated by the organizer, and if there is any disagreement, the main examination committee will be invited to arbitrate.

Each question is worth 7 points, and the full score is 42 points.

After the morning of the first day of the competition, the two invigilators received the test papers and sealed them and sent them to the designated place together to be corrected in the afternoon. The six team members returned to the hotel for lunch and rest in the afternoon to prepare for tomorrow's competition.

You must know that although there are only 3 questions in each Olympiad competition, each question is very difficult, otherwise an exam will not give three and a half hours. However, even given so much time, the vast majority of participating students are unable to complete it, and often may struggle to make only one and a half questions, or even less.

For an exam of this difficulty, the loss of spirit and spirit can be imagined, so students are given half a day of rest after only half a day of exam.

During lunch, several people couldn't help but discuss the morning competition questions.

"Alas, I've only made most of the three questions, and I haven't completed all of them, so I don't know how many points I can get." Fei Yang sighed.

Liu Beibei, a girl from Bashu, said: "I only finished one, and the other two were not completed." Wu Jizun, what about you? ”

"Complete two." Wu Jizun is as taciturn as Zhang Ziqiang.

Liu Beibei looked at Jian Fangge again and asked, "Fangge, how many have you done?" ”

"Of course, it's all done, but the accuracy is not guaranteed." Jian Fangge was still relatively gentle with the other girl among her teammates, and after speaking, she saw Liu Beibei looking at Zhang Ziqiang again, and said, "You don't need to ask, they have all done it." ”

Although he had expected it, Liu Beibei couldn't help but be stunned when he really got this answer.

Fei Yang shook his head and sighed: "Such a difficult question can be completed." You three are really perverted. ”

After Fei Yang finished speaking, he immediately heard the sound of eating around him, and when he raised his head, he met Jian Fangge's unkind eyes, and immediately realized that he had just said the wrong thing, and immediately begged for mercy: "Eldest sister, I said it wrong, you are not a pervert, you are a great genius!" ”

"Who do you say is the eldest sister?" Jian Fangge was even angrier.

"Beauty, I was wrong, just spare me."

In the afternoon, the leaders of the teams from all over the world gathered at Concord University. That is, the university that sets up the competition field in the morning conducts public marking in a large classroom.

There are more than 50 countries participating in the Olympiad this year, and counting the coordinators appointed by the United States and the members of the main examination committee, there will be more than 100 people participating in the revision of the papers, and they can only be carried out in large classrooms.

The team leaders sent by various countries are generally young and middle-aged professors who have studied the Olympiad, and there are reference answers and scoring criteria that can be compared, and there are only six papers with three questions, so it is not difficult to change the papers.

But the leaders of the countries did not take it easy. Because all the team leaders want to give as many points as possible to their students within the rules.

The same is true for Jiang Jiguo.

Although he has more confidence in the six students participating in this competition, especially Zhang Ziqiang, Fang Yuan, and Jian Fangge, this confidence is limited. Moreover. According to the news he got at noon, the test questions of this competition were the most difficult in ten years. In the morning exam, many students did not complete a single question, and even in some small countries, no one made a single question.

It's not just the questions that have become more difficult. The strength of Huaguo's main opponents this year is also quite high.

For example, Japan's Haruru Yamamoto was the third place in the 2018 Olympiad Competition, and the first and second places in the last session were due to age. He couldn't participate, so he was quite favored.

Another example is Michael, who has long been famous in the United States, was one of the perfect players in 2017, but failed to participate in 2018 for some reasons. This year, the 18-year-old Michael returned to the Olympiad competition, and his strength is likely to be even more terrifying, and many people in the main test committee recognized him as the champion of this year.

Another example is Germany's Yannick, although he is only 16 years old, he is a genius boy who has been famous for half of Europe in the past two years, especially in mathematics, and his talent has been praised by many European mathematicians and is called "God's grace".

There are also quite a lot of talented players from other countries such as the Soviet Union, the United Kingdom, France and other countries. It can be said that this session is also the one with the most talented teenagers in the past decade.

In this case, if the Chinese team wants to achieve good results, it may be unstable to rely on the strength of the team members alone. Therefore, Jiang Jiguo is ready to save face and strive to earn one or two more points for the players.

With this thought flashing in his heart, Jiang Jiguo looked at the coordinator of the United States beside him and said, "Mr. Smith, I will open the envelope and start revising the volume." ”

Smith was younger than Jiang Jiguo, in his early thirties, and said with a smile when he heard his voice: "Then Mr. Jiang, let's hurry up, there are already many people who have started, and I want to finish the work early." ”

Jiang Jiguo nodded, said no more, opened the file bag that sealed the volume, took out six volumes and spread them out and began to revise the volume.

Because it was the leader of the country who changed the domestic paper, there was no such thing as sealing player information, so Jiang Jiguo swept his eyes and knew that the first one was Fei Yang's paper. After two more glances, Jiang Jiguo frowned.

Fei Yang's three questions were not completed!

Even if he knew that Fei Yang's strength was the worst of the six, Jiang Jiguo's heart was lifted when he saw this volume-this is not good for opening the door, the first volume is not good, and the rest of the later ones are not satisfactory.

Smith also glanced at Fei Yang's roll next to him, although he didn't know Chinese, but the formulas and numbers were indeed universal, and he knew at a glance that Fei Yang had not finished the three questions, and couldn't help but smile.

"Mr. Jiang, don't hesitate any longer, hurry up and change the volume." Smith urged, and then added, "I can see that this paper is not ready, but don't think about giving more points, otherwise I won't be able to get through here." ”

Smith saw what Jiang Jiguo was thinking, and said it directly to his face, which made Jiang Jiguo embarrassed. At the same time, it was difficult for him to add two more points to Fei Yang.

Jiang Jiguo couldn't help but sigh in his heart: This Mi Chinese person speaks too directly and is difficult to resist.

Picking up the red pen, Jiang Jiguo began to change the paper one by one against the reference answers and scoring criteria.

After a while, Jiang Jiguo finished correcting it, and Fei Yang only scored 10 points for the three questions. Smith picked up the paper and examined it, nodded and said nothing.

Smith is aware of his responsibilities. It is not only necessary to supervise the fairness of the rating, but also to try its best to suppress the opponent for the players of the United States. He didn't have many opportunities to make a shot, and players like Fei Yang didn't pose a threat to the Mi players at all, so he directly agreed with the rating.

Of course, the most important thing is that Jiang Jiguo really did not favor the extra points.

Jiang Jiguo has a similar idea to Smith - he doesn't have many opportunities to make a move, even if he helps Fei Yang raise one or two points, it will not play a role in the entire team, it is better to leave it to the players who need it more later.

In this way, Fei Yang's volume was corrected, and then Jiang Jiguo finished Liu Beibei and Wu Jizun's volumes. The two scored 12 points each. One scored 15 points, and Wu Jizun got all the questions right.

Smith couldn't find fault with the scores of these two papers, so he let them go.

When he changed to the fourth Fang Yuan's volume, Jiang Jiguo's heart suddenly lifted, and he thought to himself: Fang Yuan, you must fight to do a good job, I can put the treasure on the three of you.

Sweeping the Fang Yuan rolls, he found that he had done it all, and immediately Jiang Jiguo couldn't help but look happy.

Smith's tawny eyes narrowed slightly. There was a cold light - it seemed that he had to find fault with this volume.

Jiang Jiguo quickly corrected the first two questions of Fang Yuan, and gave full marks to all of them, and the third question reached a certain step in the middle. But something went wrong, and the result was wrong. Jiang Jiguo frowned and stared for a while, and gave a 5 point.

"Mr. Jiang, this question can only score 3 points according to the grading criteria. You give 5 points, it's not just! Smith took the scroll and read it.

Jiang Jiguo didn't give an inch: "Mr. Smith, I won't be partial just because I am a student from my own country. My rating is absolutely unbiased. ”

Smith put down the scroll and said, "That's good." This paper is waiting for the arbitration of the main examination committee! ”

Jiang Jiguo couldn't help frowning even more tightly when he heard this--according to his understanding of the main examination committee, eighty percent of this paper will be sentenced to 18 points (4 points for the last question).

The fifth is Jian Fangge's paper, which is also all done, but there are also some minor problems in the last question. Jiang Jiguo gritted his teeth and gave 6 points.

After Smith looked at Jian Fangge's scroll, he stared at Jiang Jiguo and sneered, "Mr. Jiang, is it useful for you to do this?" Wait and see, your grading committee will all reject it! ”

Jiang Jiguo didn't bother to tell Smith more, and began to change the last volume, which was also the one he had the greatest expectations for - Zhang Ziqiang's volume.

Zhang Ziqiang also finished all three questions, with Fang Yuan and Jian Fangge's papers in front, Jiang Jiguo was not surprised at all. What he is afraid of now is that Zhang Ziqiang also has a problem with which question.

You must know that this is only the score of the first game of the Olympiad competition, even if all three questions are correct, it does not mean that after the second game tomorrow, all six questions can be correct.

Over the years, as the level of students participating in the Olympiad has become higher and higher, only with a perfect score can they win the championship.

Although this question is difficult, there are many geniuses. Therefore, if you want to win the championship, you still have to get a full score to be reliable.

Since Huaguo won the championship in 2013, it has been missing the championship for five consecutive years. Even in the past three years, even the top three have not been entered, and even the Olympiad organization with China has become an international laughing stock, and it is not an exaggeration to say that it is insulting to the country.

This year, three genius students finally came out, and Jiang Jiguo naturally hopes that the three of them can be ashamed of Huaguo and even win the championship again!

Thinking of these in his heart, Jiang Jiguo suddenly felt that Zhang Ziqiang's scroll had borne too many expectations, and his pen seemed to be pressing a mountain, and he couldn't help trembling slightly.

Smith saw Jiang Jiguo's hands trembling on the side, and couldn't help sneering - the first two completed rolls were all wrong, and this last one will definitely not be all right.

"Mr. Jiang, quickly change this last volume." Smith urged.
