"Xiaoying, you're definitely fine. After Liu Linna heard this, Zhengse said to Yang Ying.

"I hope we can still become classmates when the time comes......" Yang Ying smiled slightly, and turned her head to look at Duan Yun beside her......

After the opening ceremony in the morning, Duan Yun and the three returned to the hotel.

The National Mathematics Olympiad lasts for 5 days, the first day is the opening ceremony, the second and third days of the exam, the fourth day of academic reports or visits, and the fifth day of the closing ceremony, announcing the results of the examination and awarding the awards.

The CMO exam is conducted in a completely simulated IMO manner, with 3 questions per day and a limit of four and a half hours to complete. Each question is 21 points (3 times that of the IMO test questions, which is in line with the cognitive habits of Chinese people), and the full score of 6 questions is 126 points. The difficulty of the questions is higher than that of the International Mathematical Olympiad, and it is highly technical.

If the provincial and municipal Olympiad competitions are at the level of the National Games, then this national Olympiad is at the Olympic level, and the difficulty can be said to be close to the limit of high school students' problem-solving ability.

So even though it had been a period of hard training, after returning to the hotel, the three of them still got together and started the final sprint.

This time it was the first time that the three of them stood at an important crossroads that would decide their fate!

That night, the three of them studied until 11 o'clock before going to bed, and at 5 o'clock the next day, they all got up early, washed up, and followed the team leader to the hotel restaurant for breakfast.

Different from the excitement of coming to Kyoto yesterday, whether it was Duan Yun or Liu Linna Yang Ying, their faces were a little serious.

After the meal, the three and the other students of the delegation left the hotel and arrived at Huaqing University by car.

Because the examination room arrangement was random, Duan Yun was not in the same examination room as Yang Ying and Liu Linna, and almost all around his seat were contestants from other provinces.

There are only more than 30 teachers in the huge school, the seats are very spaced, but there are four teachers who are invigilators, and cameras are also installed on the front and back sides of the classroom, so there is no possibility of cheating at all!

However, Duan Yun didn't think about cheating, after all, he was a master-level math master, and his level should be above that of other students.

And when Duan Yun saw the first question of the test paper, he was immediately attracted.

Different from the previous competition questions encountered in the province and the city, the test questions of the national competition paper do have a qualitative leap in difficulty!

Moreover, in Duan Yun's opinion, the solution ideas of these test questions are completely different from the test questions he has been exposed to before, even with Duan Yun's master-level mathematical mastery, it still takes a lot of thought to perfectly solve this level of test questions.

Duan Yun felt difficult, and the other candidates were also struggling.

When they first entered the examination room, the top students from all provinces looked confident, but at this moment, everyone's faces began to become solemn, and there were ten minutes after the start of the competition, and no one started writing!

The same goes for Duan Yun.

He has been sorting out the solution ideas in his mind, and although he has thought of some methods, he still has not finalized the solution to the problem.

As the minutes passed, the atmosphere in the examination room began to become more and more dull.

According to the rules of the competition, there are three questions a day, and the time limit is four and a half hours, which sounds like a lot of time, but in fact, in terms of the difficulty of the test questions, four and a half hours is not even enough for these candidates to completely sort out the ideas for solving the questions!

Duan Yun also entered into a long period of thought.

This thought took three hours to draw!

During this period, some students in the examination room have completed the answers to the three questions, but none of them have turned in the papers and left.

In the face of such a future-determining exam, no one will submit the paper in advance for the sake of showmanship, and many students are also checking repeatedly after answering three exam questions, trying to find out their mistakes.

"Hurry up, everybody, there's still the last hour and a half. It seemed that seeing that Duan Yun had never started writing, the teacher in charge of the invigilation kindly reminded him.

The invigilator's words seemed to interrupt Duan Yun's train of thought, and then, he finally picked up the pen and wrote his name on the exam paper in a regular manner......

"Ding~"

With the ringing of a bell in the corridor, the first day of the competition officially ended, and Duan Yun reluctantly glanced at the exam papers on his desktop, and then got up and left the examination room.

If the provincial and municipal Olympiad competitions did not challenge Duan Yun much, then the test questions of the National Olympiad made Duan Yun truly experience the 'happiness' of specializing in Olympiad mathematics, or these test questions were very interesting, so that he could immerse himself in them.

"Duan Yun, how did you do in the exam?" When Duan Yun left the examination room, Yang Ying and Liu Linna stepped forward to ask for the first time.

"It's okay. Duan Yun sighed lightly when he heard this, and he didn't seem to be very confident.

"Forehead" saw that Duan Yun's expression was a little solemn, and a trace ......of loss flashed in the eyes of Yang Ying and Liu Linna.

There is no doubt that Duan Yun is now the absolute core of this Olympiad group, if he can't achieve good results, then the entire heroic team will have no chance of winning at all.

"How did you do in the exam?" Duan Yun asked rhetorically to the two girls.

"That's a tough question...... It's different from the exercises we've done before. When Liu Linna heard this, she frowned and said.

"I'm a little worried......" Yang Ying's face on the side at this time was also not very good-looking, obviously the difficulty of the exam questions this time was far more difficult than she expected.

"Don't worry, you have to understand, we think the question is difficult, other players are not easy to do, and besides, this game is not over yet, and we will work hard tomorrow." Duan Yun comforted Yang Ying, then patted her shoulder and said, "It's good to work hard, as for the results, let it be fate......

"Hmm. Yang Ying's expression was a little gloomy, although she had worked hard for this competition for a long time, she still felt that the exam situation was not good.

Sitting in the car back to the hotel, several people were speechless all the way.

After entering the hotel lobby, Duan Yun saw several students from the same province happily chatting about the morning exam, obviously they were quite satisfied with their performance.

Seeing this scene, Liu Linna and Yang Ying also frowned, their faces were very ugly, and after getting out of the elevator and separating from Duan Yun, the two girls returned to the room with their own concerns.

Back in the room, Duan Yun also lay down directly on the huge double bed in the president's private room, his eyes looking at the ceiling in a daze.

He didn't want to think much about the morning exam, and in his opinion, no matter how high or low the score was, it was irreversible, and he just wanted to sleep well now, after all, it took him a lot of energy to answer the questions in the morning.

However, just as he was about to take off his shoes and sleep, the mobile phone in his trouser pocket suddenly rang, took out the number and looked at it, and was stunned for a moment, it turned out that the person who called him was actually the director of the Provincial Football Management Center who had been to his house before and had several encounters - Gao Bo!
