Chapter 38

The next day was the opening ceremony of the National Mathematical Olympiad!

200 high school mathematics elites from all over the country gathered here.

It's really a gathering of masters!
The opening ceremony of this level of national competition is quite grand.

But if you participate in the scene, it is actually quite boring.

Because you have to listen to the speeches of the leaders on the stage here, and you will stand weak below.

The leaders were happy to speak at the top, and the students from various provinces below were also very happy to desert.

"Look, the few over there should be students from Hengshui No. [-] Middle School, right?"

"It looks like it should. It is said that four students from Hengshui No. 4 Middle School will participate in the National Mathematical Olympiad this year!"

"mmp, that's amazing! It's the second best high school in the country. It's really full of talents! For example, our province only had 4 people participating. It is said that the province where Hengshui No. 4 Middle School is located has eight people participating. But they Hengshui No. [-] Middle School It actually took up [-] places, which is awesome for my brother."

"Hey~ Their province is supported by Hengshui No. [-] Middle School! Over the years, Hengshui No. [-] Middle School has won countless gold medals in the National Mathematical Olympiad. They have even won a lot of gold medals in the International Mathematical Olympiad."

"Also, the three over there seem to be Huazhong Affiliated High School, which seemed to be the No. 1 high school in the national high school rankings last year. It is really the best in the country! This year they will all be in the top 30, and they will even become participatory One of the six in the International Mathematical Olympiad!"

"That's right, students from Huazhong High School, Hengshui No. [-] Middle School, Changsha Middle School, etc., which are the top ten schools in the country, will definitely be able to enter the top [-]! They all have the opportunity to participate in one of the six people who participate in the international competition. Olympiad competition!"

"They are too strong!"

Whether it is the students or the teachers of the team leaders, they are all discussing in a low voice.

After all, the students of the top ten high schools in the country are really against the sky.These schools take turns to participate in the International Mathematical Olympiad to win gold medals.All of them are awesome!
After the boring opening ceremony on the first day, the second day finally started the exam!
The National Mathematics Olympiad is divided into two days of exams, with three questions in one day, and the time is 4.5 hours.

This time Xiao Jun did not take the same exam as Yang Qianqian.

The exam has begun.

Xiao Jun who got the test paper glanced at the first question:
1. A, B, C, and D are four different points arranged in sequence on a straight line. Two circles with diameters AC and BD intersect at X, Y. The straight line XY intersects BC at Z. Let P be the straight line XY At a point different from Z, the straight line CP intersects the circle with diameter AC at C, M; the straight line BP intersects the circle with diameter BD at B, N.Prove: AM, DN, XY three lines have the same point.

"It feels like a big head in an instant!" Xiao Jun flipped through the knowledge reserves in his mind, but found nothing!He didn't give up, and planned to use his strong IQ to come up with a solution to the problem.

After 10 seconds, he gave up, and he found that his IQ was insufficient!
This kind of questions should be given to people with an IQ above 140. His IQ is only 120, so he gave up decisively.It is estimated that he can solve it in seconds when his IQ is 250.

"Since IQ is not good, I can only rely on hacking!" Xiao Jun sent the three questions to the [Xueba chat group] with his own eyes.

Xiao Jun: Old men, get up and work!
Comet Takishima: Group leader, are you taking the Mathematical Olympiad exam now?

Xiao Jun: Yes!Hurry up and help~ It's best to ask for a full-score answer or something.

Comet Takishima: No problem!
Sheldon: Pigs~ I'm coming~~ Hey, I'm a step late!Comet Takishima, wait for me~~
……

An hour later, Xiao Jun took the answer that Takishima Comet and Sheldon worked out together and wrote it down.

"Hey, all three questions have been solved!"

Xiao Jun, who finished the three questions, was bored and observed the surrounding area.

There are a total of 25 candidates in this examination room.

He saw that some people seemed to have nothing to love, obviously they couldn't find a way to solve the problem.Some people wrote and drew on the draft paper, and their foreheads were sweating, which is probably not enough.

Only a small part is quite calm!

But he should be the calmest one.Not surprisingly, he can definitely get full marks for the three questions today.

This is the end of the first day of exams.

When he leisurely returned to the dormitory, he saw that several other members of the Jiangbei provincial team had also returned and were chatting with the provincial team leader, Mr. Jiang Song.

"Xiao Jun, how did you do in the exam?" Wu Junhua from Jiangbei High School asked Xiao Jun.

"It's okay." Xiao Jun said lightly.

"Are you sure or not sure?" Teacher Jiang Song interrupted at this time.She was still very impressed with Xiao Jun.After all, he won the No. 1 competition in Jiangbei Province, so his potential should be very high.

"I'm sure!" When it comes to this point, Xiao Jun is also embarrassed to say that he is not sure, is he?

"Hey~ I'm sure about the first and second questions, but I have almost no idea of ​​how to solve the third question, so I just wrote some points. The score will definitely not be high then!" Zhou Xiaoyu, who is also from Jiangbei High School, stomped her feet.It seems that there is some self-pity that I can't do that question!

"Yang Qianqian, what about you?" Xiao Jun looked a little dull when he saw Yang Qianqian was silent beside him.

"Like Xiaoyu, I'm not sure about the third question." Yang Qianqian sighed.

"It's okay, today is only the first day, and you still have a chance tomorrow. Besides, you don't have to do all the questions! If you get the perfect score for the first question and the second question, you may also There is a good chance to enter the top [-]. After all, others may not be able to do all of them, can they all get full marks? There are very few who can get full marks." Jiang Song cheered.

"hope so!"

On the next day's exam, Xiao Jun once again felt that his IQ was insufficient, wishing that he had an IQ of 250!Because the three Olympiad test questions on the second day were even more difficult than yesterday's!
So he had no choice but to turn to the Xuebas in the [Xueba Chat Group] for help again.

The next day's exam ended simply like this.

The morning of the next third day was an academic report, another boring speech.Fortunately, the afternoon is a tour!Many people cheered.The results will be announced the day after tomorrow, and it will also be the closing ceremony!
In the afternoon, everyone went to visit the jewel in the palm of Tianhai City.

Then there was a dinner party or something, anyway, I had a lot of fun.

Everyone has forgotten the devil's exam for these two days!

Of course, there are still many people who are worried about their grades.

Because if you can enter the top [-], you will have the opportunity to participate in the training of the National Mathematical Olympiad Team, and you will have the opportunity to be selected as one of the six people to participate in the International Mathematical Olympiad Competition!
As for Xiao Jun, he didn't bother to think about it, anyway he had fun and had fun!
