The Protagonist’s Halo

Chapter 46 I have a halo

Not only the teachers and students who participated in the competition with Cheng Yin were stunned,

After the preliminaries, Cheng Yin’s reputation quickly spread in the physics groups of several major high schools in the city. Many people know that Donghua has produced a particularly powerful physics competition seed, and he showed off in front of the teachers in the preliminaries. A handful.

Not only the question is super fast, the accuracy of the preliminary questions is 100%, and the memory is abnormal. You can also write down the whole test paper and the answers to the questions in the process of solving the questions silently.

Don’t think that memory is so good that it only plays a role in liberal arts, and it is a big killer in every subject.

The preliminaries came out soon. Cheng Yin didn’t have any unexpected full scores, but it was not the only full score, but tied for the first place with another high school student in this city. He entered the semifinals smoothly. The physics semifinals date was also announced. In late September, there is still more than half a month left.

But before that, there will be provincial competitions in the number of leagues.

The National High School Mathematics Contest is the highest-level mathematics competition in Chinese high school mathematics. Its status is much higher than that of the mathematics competitions organized by the provinces. The final is the famous CMO, and it has the highest gold content, no doubt.

The competition is divided into two parts, one test and two tests. Only about 90 students from across the country who have achieved excellent results in this competition are eligible to participate in the “Chinese Mathematics Olympiad and (CMO) National Middle School Student Mathematics” hosted by the Chinese Mathematical Society. Winter Camp”.

Winners can also automatically get the qualifications for admission to major universities, and there are also independent enrollment and score reduction awards for the next few times.

A few days before the test, Mr. Xu frantically trained them to do the classic question types and various variants of the final mathematics problem, wishing to put all the knowledge and skills that may be tested in the competition into their minds.

Teacher Xu also knew that Cheng Yin had already scored full marks in the physics preliminaries. He directly told all the participating students, “It is okay to hand in papers in advance, provided that you think you can get full marks.”

Jiang Yunhao’s first reaction when they heard it was to look at Cheng Yin.

Cheng Yin’s full score in the physical preliminaries was also publicized by the school. Although there is more than one full score in the city, and the province even heard that there are twelve or three, nearly 60,000 people participated in the competition, and more people are on the sidelines with full scores. There are more than 50,000 students who have not been touched.

Xu Jun’s vision is also a bit complicated, his score is also very high, entering the semi-finals is not a problem, but there is still a gap with the full score.

And it’s still difficult to bridge the gap.

Precisely because he also participated in the material competition, he knows how difficult it is to get full marks.

What’s worse is why he is not surprised at all, and he still has a little habit of breaking. In the matter of competition, he is better than the process of sound, and in the competition of numbers, the gap between him and Cheng Yin is even greater. Xu Jun has to admit this.

Maybe it was because he was hit by Cheng Yin a lot in the math competition training class. Since the first time he took the initiative to participate in the discussion and problem solving, he was crushed by Cheng Yin at will. He also secretly wanted to try him and Cheng Yin. How big is the gap?

Then she was crushed into dregs without exception. Cheng Yin said that it would be solved in five minutes, and it would definitely not exceed five minutes and one second, and she even left room for herself.

Xu Jun even suspected that there were other math problems that could hardly beat her.

Just like what Teacher Xu said, it also gave them some pressure, and Xiao Han could take it for granted, nodded without hesitation, and said, “Teacher, I will.”

Jiang Yunhao and the others screamed crazy in their hearts, saying that it was you, don’t behave as if you listened carefully and took it seriously.

The first test is from 8 AM to 9:20, a total of 80 minutes. As soon as the paper is issued, there are eight fill-in questions and three answer questions, a total of 120 points. The difficulty is higher than the multiple-choice questions in the college entrance examination. The finale, the finale of the answer.

But this was just a warm-up, and Xiao Han believed so.

More examinees feel that you tell me this thing is a warm-up, you are afraid that you are not assing me.

Xiao Han repeated the scene in the physics preliminaries, but this time she stared at the test questions for a little longer before starting to write.

According to a professor who was specially invited by the school to give them a competition training class, number competition and material competition have always been at the top of the five major competition contempt chains. The difficulty of the two is about the same, and there are even many things in common. The first-class chemistry competition, the biological competition is at the end.

IO, or information competition, has always been the most out of place in the Big Five, because in their eyes, all other competition students do not know how to play computers.

Although this is meaningless, it is mostly a joke. As long as one can win the championship in one of the subjects, no one will say water stupidly, only the championship is worthy of disregarding others.

But there is no doubt that these two subjects are indeed the most difficult of all competitions.

The main knowledge area of ​​physical competition is very wide, starting with more than 70% of college physics knowledge, and there are many incomprehensible theorems and questions, and with the addition of advanced mathematics, the difficulty is rising.

The number competition is mainly about high school knowledge and development. There may be some college content in the number theory combination. The difficulty of knowledge may not be difficult, but the topics are all strange. It depends on brain, IQ, and feeling, or it is a flash. Inspiration.

Xiao Han seems to be the most indispensable for inspiration. Relying on years of experience in dealing with these two subjects, her knowledge expansion can be said to surpass any student. She is aware of the elusive theory of theory and the theory of thinking derivation.

Moreover, for ordinary students, Xiao Han can easily understand the obscure and complicated formulas.

She can always think of more than a dozen ways to solve a question. No matter how tricky it is, Xiao Han can’t be embarrassed, and she can always think of a way to solve it.

This is also the real reason why both the mathematics teacher and the teacher Xu of the competition class recognized her talent in mathematics.

Of course, thanks to the small gap between her last world and this world, a lot of experience and knowledge can still be used.

It is not like a college bachelor who has studied poetry and became illiterate in the interstellar age.

For Xiao Han, the time required to warm up is naturally not long, it can be done in forty minutes.

After reviewing the answer sheet, Xiao Han nodded in recognition of himself, and then raised his hand to hand in the paper.

Without mentioning the invigilator’s shocked eyes after she handed in the paper, Xiao Han had already left the examination room.

Teacher Xu is also the leader teacher of Donghua High School this time. He was not too surprised to see Xiao Han handing in the paper ahead of time, but the teacher next to him was shocked on the spot, “Mr. Xu, you student won’t hand in a blank paper.”

I really can’t speak. Teacher Xu gave him a blank look, and then ignored him. He took out the draft paper and pen he had prepared, and handed it to Xiao Han. He also said one more sentence, “There is plenty of time, so write slowly. ”

I heard from Teacher Wu that Cheng Yin would still have nothing to do if he handed in the papers in advance.

Xiao Han choked, but still silently took the paper and pen, and began to write silently in the lounge.

Skip the process of calculating in your heart, faster than in the examination room, less than half an hour is good, there are still ten minutes before the end of the exam.

Teacher Xu performed the calculation carefully by herself again, and the answer was indistinguishable from Cheng Yin, and it was not even as beautiful as the answering process she wrote.

The teachers in other schools who came to see the excitement were shocked and couldn’t believe it. The teacher who had previously suspected Xiao Han to pass the papers blurted out, “She is the memory metamorphosis of the previous physics group and got the full score of the preliminaries. sound.”

Teacher Xu put away Cheng Yin’s draft paper satisfactorily, and cast a scornful look at the other teachers.

Now I know how awesome my students are, huh.

The other teachers in the lounge yelled, “Don’t, don’t put it away first, let us also see how you answer the student question.”

Teacher Xu did not share the virtues at all, and as the announcement sounded at the end of the trial, the teachers were busy to see their students, and it was no good to pester Mr. Xu anymore.

The rest time between the first trial and the second trial was only 20 minutes, and it was time to take a break with a sip of water.

“I feel that this year’s semi-final questions are so difficult. Is the question group abnormal?”

“What the **** is the last big question? Isn’t it just a circle? I almost saw the flowers coming, and I didn’t think of how to prove it.”

“Just use the vector to find it. Use point P to draw a straight line and two other lines…”

The classmate’s face became more and more bleak, “Stop talking, I just want to be quiet now.”

There are still a small number of people discussing the answers, and more are adjusting their mentality. After all, there are more difficult second trials waiting later.

The second test is from 9:40 to 12:10, a total of two and a half hours. In these 150 minutes, there are a total of four solutions to solve, a total of 180 points.

Don’t look at only one A4 size test question, one answer sheet, how many candidates have to write more than a dozen draft papers for these four big questions, most of them can’t finish it in two and a half hours.

These four major questions are plane geometry, algebra, number theory, and combinatorics. The test sites are very fixed, but the content is flexible and good, making people want to cry because it changes so that it is difficult to understand.

At the moment when many contestants saw the problem, their mentality collapsed in half, and the remaining half were struggling for the last one hundred and fifty minutes.

While participating in the math competition training, Xiao Han self-consciously constructed a set of knowledge system in the memory palace belonging to the mathematics subject.

The number of questions is indeed a coincidence. There are traps everywhere, like deliberately intrigue with the examinee. The first question is what appears to be a sequence of numbers but is actually a number theory. If you don’t see it, you will want to break the world. There is no result, the key is that one of the equations is very long in Euclidean style, and the overall idea must be a bit similar to the proof of division.

The second question is very interesting,

The interesting part is not that it is difficult to solve the problem, but that after Xiao Han came up with five conventional ideas, he would naturally produce the sixth solution.

And this sixth is the most straightforward and simple.

This is similar to how the depth of thinking determines the candidate’s answer.

Xiao Han thought, the first five conventional problem-solving ideas, no matter who they are, all points will be given, because the answer steps are correct, but the scheming of the person who asked the question is played here, and it is regarded as the examinee of the question. Whether you are willing to dig deeper and discover the beauty of mathematics, or whether you have this kind of depth of mathematical thinking, you can think of the sixth solution.

And this process, it is rare for Xiao Han to have a wonderful feeling of swimming in the ocean of mathematics and unconstrained.

After thinking about it, Xiao Han wrote the sixth solution in a smart manner.

Guessed the intention, but she came up with the solution, why not write it, Xiao Han is probably not the kind of person who is willing to pretend to be mediocre.
