At half past one o'clock in the afternoon, the bell rang, and the second half of the four-and-a-half-hour session officially ended, and the CMO national final exam officially ended.

Xu Chuan and Gong Rihui were in the training room, waiting for the other candidates from southern Hunan to return.

At this point, the Shonan training team is still doing a good job, no matter whether the topic will be done or not, I have to stubbornly persist until the last second.

Maybe you'll be inspired in the last few minutes?

But mathematics is such a thing, it will be a will, it will not be a no, you will force a person to grow wings and fly into the sky, he may not be able to make math problems that he can't do.

"Teacher Gong, I'm going to die, I'm going to die, the second half of this national duel is so difficult, I don't even have time to check."

Outside the training camp, I didn't see anyone, I heard his voice first, and the noisy voice of the little round-faced Lu Tianrui sounded.

"Rub, you're done, I haven't even finished the question."

"The first question was so difficult, so I made the first question."

"Don't say it, I only made the first two questions in the next two big questions, how can it be so difficult to be like this in the second half of this year."

"The first half was fine, but in the second half everyone was numb."

"In this year's national decision, I estimate that it will be about 50 points at most."

"Look to the sky! I'm pretty much the same. ”

"I'm probably thirty or forty points."

Accompanied by Lu Tianrui's voice, there were also the voices of other students in Xiangnan, and immediately, a group of people appeared in the training room.

"This year's topic is a little more difficult, but everyone just did their best."

Gong Rihui smiled and comforted everyone in the room, the exam has already been completed, no matter how strict it is, it is useless.

And Xu Chuan rewrote the question and showed him it, the question in the second half is really difficult, and it is indeed a little difficult for this group of students to solve it all in four and a half hours.

In particular, it took him nearly an hour to solve the plane geometry.

As for Xu Chuan, that's another matter

Since the end of the provincial training, he has not seen this student as an ordinary student, in his eyes, Xu Chuan's mathematical ability is definitely professional, and he may be on par with his professional mathematics teacher.

"Brother Chuan, you handed in the papers in advance again, you pervert! You can turn in such a difficult question in advance! ”

After entering the training room, Lu Tianrui saw Xu Chuan standing next to Teacher Gong Rihui at a glance, and suddenly looked resentful.

He barely finished all the questions, and he didn't even have time to check, so he didn't know whether it was right or wrong, but it turned out that this pervert was submitted in advance, which was really shocking.

Xu Chuan glanced at the little round face and didn't answer, if this is a stubble, it is estimated that the back will be endless.

However, after handing in the paper in advance, he and Mr. Gong Rihui wrote out the questions and answers, which would be convenient for teammates to check.

......

The national decision of the number of competitions is over, and the marking work is in full swing.

In the Mathematics Society, the six professors who participated in the problem and the other four directors who were transferred from the board of directors conducted the marking together.

Ten people, an average of 40 test papers per person, have to read all of them in a day and a half, which is still very energy-consuming.

After all, this is a national decision, and although there is only one standard answer to a question, many candidates may use some different methods and ideas to solve the question.

Different paths lead to the same end, just like when the school training team, Xu Chuan used calculus to do analytic geometry.

And every time the paper is marked, the teacher must carefully check the answers of these students.

"This class of students can't do it, the first half is a little better, and I have seen several blank papers in the second half, alas."

In the marking group, Academician Zhang Weiping, a professor of geometry, shook his head and put a zero on the white roll in his hand, and then sighed.

The judges who were reading the papers raised their heads one after another.

"Lao Zhang, have you ever thought that it may not be that the students are not good, but that the questions you come up with are too difficult?"

"That's it, the question in the second half was originally a paper A, but you stubbornly brushed all three questions in the A paper."

"Excuse me? In the second half, I had to do the geometry problem for at least an hour. ”

"I looked at it, and this year's average score is estimated to be less than sixty."

"Isn't it just a meal, you're really embarrassed by these students."

"Is it difficult? I don't think so. Zhang Weiping pushed the eyes on the bridge of his nose and retorted.

Hearing this, the white-eyed brushes in a row in the marking classroom were lost.

It is not difficult for a top mathematician and an academician of the Academy of Sciences with extremely high achievements in geometry to come up with a difficult topic for this group of students, each of whom is less than eighteen years old.

"Huh? This student is good, he solved all the first questions in the second half, and he solved them all correctly, the steps were correct, and the answers were correct. ”

"I'll look at the back, he has done the last two big questions, and the answer is right."

"Lao Zhang, you made a mistake, it seems that there are perfect score players this time."

Suddenly, a marking teacher shouted in surprise, attracting the curiosity of the other judges.

The difficulty of this year's CMO national final questions is obvious to all, especially the second geometry question, which is the first in the previous geometry questions.

Judging from the performance of candidates in previous years, there may not be a full score this year, and everyone was surprised that a full score player suddenly appeared.

On the side, hearing that someone had completely solved the second geometry of his own, Zhang Weiping suddenly couldn't hold it back, put down the answer sheet in his hand and walked over.

"I'll see, I'll see."

snatched the test paper from another grading teacher, and Zhang Weiping couldn't wait to review it.

Several minutes passed before Zhang Weiping came back to his senses and sighed.

"There are talents in the country."

Several judges who came over to watch from the side also admired.

"Yes, it's good, the student got a perfect score in the second half."

"Hahahaha, Lao Zhang, it seems that you owe us a meal alone."

"I'm going to Juchun Garden to eat Buddha jumping over the wall and braised shark fin!"

Zhang Weiping glanced at several directors of the question group, and said unconvinced: "A full score in the second half does not mean that a full score in the first half can also be scored. ”

"Heh, do you believe this yourself?"

"That is, touch your own conscience and ask it to believe it?"

Hearing this, Zhang Weiping was immediately deflated.

Indeed, he didn't believe it himself, the three most difficult questions in the second half were solved by this student, completely correct, full marks, and it didn't make sense that the easier questions in the first half yesterday couldn't be solved.

And they have already reviewed yesterday's test papers today, and there are quite a few who have got full marks.

"It would have been a little more difficult to come up with the question earlier, and this time it was really a big loss."

Zhang Weiping muttered, returned the answer sheet in his hand, and went back to read the paper.

So you may never know why the questions in this competition or the college entrance examination are so difficult.

Maybe it's just a bet made by the teacher of a certain group and someone else.
