From top stream to scholar

Yu Hui's math score is the first in the whole grade in the ordinary class, and his math foundation is even more solid than Yu Wanzhou's. Moreover, it seems that some difficult math problems are definitely much better than Yu Wanzhou's in solving math problems.

But Yu Hui just smiled awkwardly and said, "I'm not sure, it's also my first time participating in a math competition."

"What about you?"

"It's my first time too, and I'm not sure."

Yu Hui said with a smile, "It seems that the two of us are both fallen in the world!"

"Who says it's not?" Yu Wanzhou echoed, "I don't know how difficult the math competition will be."

"Well... Anyway, I read it online and said it was quite difficult." Yu Hui's eyes lit up, "Do you go online?"

"I seldom surf the Internet recently, what's wrong?"

"I looked at it yesterday and it seems that there is a special discussion group about mathematics competitions. I don't know many people in it."

"Probably the world of the great gods." Yu Wanzhou is relatively relaxed. He doesn't know much about these discussion groups, but he knew a long time ago that there are thousands of post bars dedicated to discussing competitions, and there are occasional discussions in various forums. There will be discussions about these competitions.

He was not surprised at all. In his opinion, it was a world that was very far away from him and could not be touched.

Now if someone tells Yu Wanzhou that he can achieve excellent performance in the mathematics competition, I believe that the first person to complain about this matter will definitely be Yu Wanzhou himself.

He hadn't thought about such a thing at all.

"By the way, Yu Wanzhou, you are also good at math." Yu Hui said, "How about we learn from each other sometime?"

"Okay." Yu Wanzhou didn't refuse. Studying with a good student like Yu Hui might give him some new ideas.

"I heard that the homeroom teacher is going to set up a study group, and then we will be in one group!" Yu Hui had never spoken to Yu Wanzhou before, but Yu Wanzhou was in his class anyway, and he didn't know the others very well.It seems that these people should all be students of the top class, he doesn't know each other, and he has no other choice but to talk to Yu Wanzhou.

He bit the bullet and talked to Yu Wanzhou. Surprisingly, Yu Wanzhou was quite easy to talk to.

He is not as arrogant as he is, probably because Yu Wanzhou never chats with others, or is immersed in his studies every day and does not take the initiative to talk to others, which makes people think that Yu Wanzhou is quite arrogant.

Yu Hui thought about it in his heart, "All the students in our class think you are very difficult to talk to."

"Oh?" Yu Wanzhou said with a smile, "I didn't expect me to be a talking point in class."

"That's right, you are quite famous in school." Just as he was talking, he saw someone he didn't know pass by, and looked at Yu Wanzhou for a long time, "Are you Yu Wanzhou?"

"I am." Yu Wanzhou nodded, the man was either excited or curious, "You are also here to participate in the math competition."

"Yes." Yu Wanzhou said jokingly, "Can't I come to participate in the math competition?"

The person talking to Yu Wanzhou chuckled, "It's not that I can't participate, but I didn't expect you to come to participate. It's quite strange."

"Thank you!" Yu Wanzhou looked at the man sitting in front of Yu Hui, "You two know each other?"

"classmate."

"Are you really studying in our school?" The man looked shocked, "I thought it was a rumor."

Then he muttered, "I haven't even seen you."

Yu Hui smiled at Yu Wanzhou, "Look, let me tell you that you are famous."

"..." Yu Wanzhou didn't express anything, and neither would he.If he is famous, he is famous, what else can he do.

When the invigilator walked into the examination room, everyone was already sitting in their seats, waiting for the invigilator to come in and distribute the test papers.

Because the rules of the exam are actually very clear to everyone, the invigilator simply said, "Don't whisper, don't whisper, do it yourself."

Most of the students have no possibility to participate in the semi-finals or the provincial and municipal finals, just to join in the fun.

Before No. [-] High School, no one was able to enter the semi-finals, so the teacher didn't say anything in particular.

When the test paper was found, Yu Wanzhou was a little confused.He found that his mathematical knowledge was not enough. The first question was plane geometry.

He looked left and right, not knowing where to start.Glancing to the side, the person sitting next to him, who had an empty seat, also had a sad face.

Turning his gaze back to his paper, since he was not sure about the first question, let's do the second question first.

However, the second question broke him even more than the first one!The first question is plane geometry, and the second question is directly about number theory.That was number theory, and it was very difficult for him to deal with this problem based on the trivial knowledge he had learned in high school and college.

Do you want to be so exciting?It was so violent at first.

OK!Give up the first two questions, he doesn't believe in the second question, he still can't do it.

The third question is still plane geometry, but at least it is simpler than the first question.After racking her brains, Yu Wanzhou finally found a method from her memory—Simson's theorem, that is, through any point on the circumscribed circle of a triangle that is different from the vertices of the triangle, draw a perpendicular to the sides or their extensions , then the three vertical feet are collinear. ①

After finishing the third question, Yu Wanzhou reckoned that almost half of the time had passed. The math competition really deserves to be a math competition.Based on his knowledge, it is impossible to pass the preliminary competition.

One operation is as fierce as a tiger, but at first glance, I look like a two hundred and five!

Fortunately, there are multiple-choice questions and fill-in-the-blank questions in the back, which are relatively simple, and Yu Wanzhou keeps doing it.The papers of the preliminary mathematics test made him sweat profusely. This is not participating in a competition, it is simply a complete and ruthless mockery of his ignorance.

The last question was made by Yu Wanzhou in the midst of the chaos.When the teacher asked to hand in the papers, Yu Wanzhou looked exhausted, and he hadn't moved on the first two questions at all.

That's three to 10 minutes. As for the last big question, he used the second mathematical induction method. As for whether he can get it right, Yu Wanzhou really doesn't know.

After handing in the papers, Yu Hui sighed, "It's too difficult, I guess I have no hope."

"Me too..." Yu Wanzhou didn't know whether to laugh or cry, "Although I know I'm bad at math, this paper really hits me!"

"That's not it!" Yu Hui patted Yu Wanzhou's shoulder, "Okay, don't think so much."

"I heard that the pass line for the preliminary competition is 60 points, and only after reaching 60 points can you participate in the next preliminary test." Yu Hui spread his hands, "I guess there is no chance."

"Me too..." Yu Wanzhou recalled the papers she had done, "The first plane geometry is so difficult that I can't do it at all. The second number theory question is confusing to me. The third question ..."

"The third question can be solved using Simson's theorem." The person sitting in front of Yu Hui walked up to them with a smile and said, "The subsequent multiple-choice questions and fill-in-the-blank questions are fairly simple, and the last question uses the second mathematical induction method." It can also be done. But if you are not careful when calculating, it will probably be miserable."

"My name is Chen Chen!" The man was a little familiar, "I'm in Class Two and Three."

"Senior!" Yu Wanzhou looked at Chen Chen, "It seems that the senior should be sure to enter the preliminary examination."

Chen Chen said with a wry smile, "That means I was able to pass the preliminary round. I also participated in it last year. The papers in the preliminary test were much more difficult than the papers in the preliminary round. There is no possibility of entering the semi-finals."

"Forget it, don't think so much, let's go early."

"When will the results come down?" Yu Hui glanced at Chen Chen before leaving.

"It should be around the National Day." Chen Chen pondered and said, "I don't know too well, there may be a time error."

Yu Wanzhou tugged on Yu Hui's clothes and said, "Do you think you can enter the preliminary examination?"

"I just want to see how many points I can get in the test." Yu Hui shook his head and said, "As for entering the first test, I haven't even thought about it."

"That's right." Yu Wanzhou nodded, "I don't know how many points I can get in the exam." If he can get fifty points in this paper, it will be blessed by the gods and Buddhas.

"Chen Chen, go play basketball!" Someone called Chen Chen loudly. At this time, Chen Chen said to Yu Hui and Yu Wanzhou, "Goodbye, let's talk later, I'm going to play basketball."

After Chen Chen left, Yu Hui thought about it and said, "I always feel that this person is familiar to me?"

"Really?" Yu Wanzhou and Yu Hui were walking on the boulevard when Yu Hui suddenly yelled, "Hey, isn't he Chen Chen from Class [-] and [-]?"

"Didn't he just say that he is from Class Two and Three?" Yu Wanzhou was a little puzzled, "What's wrong?"

"I heard that he has good grades and is quite handsome. He is very popular with girls. He is also the school grass of our Eighteenth Middle School..."

"Oh!" Yu Wanzhou didn't pay attention, but pointed out the problem, "I heard that Xu Tao is also a school grass..."

"..." The two looked at each other, and they were not interested in talking about it for a moment.

Xu Tao blasphemed in class every day, he had no image at all, and he didn't know what those girls liked about Xu Tao.

After separating from Yu Hui, they came to the school gate.Yu Wanshen was already waiting for him outside the door and saw his unhappy face.Yu Wanshen said with a smile, "What's the matter? Did you fail the exam this time?"

"It's not that I failed the exam." Yu Wanzhou shook her head, "It's because I felt the injustice of this world."

"What?" Yu Wan was stunned for a moment, "Why do you say that?"

"The question is too difficult. Why can someone achieve full marks? I can't even estimate how many points I will get in the test."

"Then how much do you think you can score?"

"Forty or fifty is already long live." Yu Wanzhou rubbed the center of her brows, "It's too difficult. It's different from the basic knowledge of previous exams, and the difficulty has increased a lot."

Yu Wanshen wasn't surprised, "After all, it's a competition. It's a test to select mathematics talents. It must be difficult."

"Don't be discouraged, work hard, and strive to get to the first line. We don't compare with geniuses, we compare people with others, and it makes people mad!" Yu Wanshen comforted him, "Go, brother will take you out to play and relax."

"Brother, where are we going?"
