Reborn Technology Scholar

Chapter 12 National Competition

Qin Yuanqing, as the captain of the provincial team, gave another encouraging words to everyone.

Chicken Soup for the Soul, many people hate it.

But at critical moments, Chicken Soup for the Soul can often play a huge role.

"Friends, now Shancheng University has gathered the best mathematics students from all over the country. The stage has been set. Are you ready?" Qin Yuanqing glanced at everyone.

"Ready!" the crowd roared loudly.

Sometimes, a lot of words won’t actually work. As representatives of the provincial team, they are all the best mathematical geniuses in Fujian Province this year. They have their own arrogance in their hearts. If this arrogance is ignited, they can rush faster than anyone else.

fierce.

The vice president couldn't help but feel a little relieved when he saw this scene.

On November 15th, the entire Shancheng University seemed to have a solemn atmosphere. The participating representatives held their ID cards and admission tickets and went to the examination room under the leadership of volunteers. No one was allowed to bring their mobile phones or any electronic devices.

Qin Yuanqing entered his examination room, found his seat and sat down, closing his eyes slightly to rest. There was still half an hour left before the exam. This half hour should not be wasted. He just needed to adjust his state.

At 8:58 minutes, the radio announced the order of the examination room and the notes for candidates. At the same time, the invigilator distributed the test papers. At 9:00 sharp, the radio announced that the exam had officially begun.

Qin Yuanqing started to fill in his name, admission ticket number, and ID number. Then he did not rush to answer the questions, but quickly browsed the test questions.

Afterwards, Qin Yuanqing began to answer questions.

The multiple-choice questions are obviously a higher level of difficulty than those in the provincial competition. Each question must be treated as a solution and the steps must be listed in order to get the correct answer.

Each question is based on knowledge that appeared in high school, but if it is not extended and expanded, it will be impossible to solve it.

After completing all the multiple-choice questions, Qin Yuanqing did not rush to fill in the blanks. Instead, he filled in the answers to the multiple-choice questions on the answer sheet and checked them once before doing the fill-in-the-blanks.

Fill-in-the-blank questions are actually much more difficult than multiple-choice questions. After all, the four options for multiple-choice questions are listed there. If the answer you come up with is not among these four options, it means it is wrong. You can check the steps to find the wrong place. However,

There is no way to check this fill-in-the-blank question. You just write whatever answer you give. As for right or wrong, you don’t know at all. You will only know when the answer is reviewed and the answer comes out. If you encounter a trap set by the teacher who wrote the question, you will fall into a deep trap.

There will be more people who don’t come.

And this situation is still common. Every year there is a question that misleads students with mischief, and students do not find out that they get the wrong answer.

After Qin Yuanqing filled in the answers one by one, he started to answer the questions. There were only three answer questions, each worth 20 points.

The first question is an unbeatable function question, but it is a function combined with geometry, which requires graphing and analysis before it can be verified. This question is the least difficult of all the answers. If you can't answer this question, then the second answer question

, the third answer does not require much thinking at all.

After Qin Yuanqing finished solving the first solution question, he continued to do the second solution question. This question was about solving inequalities, which incorporated logarithmic operations and multiple powers. Qin Yuanqing found it interesting because there were two solutions to this question, and

These are all high school knowledge points.

Sure enough, the most important thing in the high school mathematics league is mathematical thinking!

However, it is true that mathematics relies on talent. As long as those with high talent have correct thinking and logic, their answers will not be wrong.

A large number of college students have studied advanced mathematics, algebra, etc. in college, but their level is not even comparable to the mathematics level of some high school academics.

After Qin Yuanqing finished answering the second answer question, he started to work on the third question. This question is about functions, geometric combinations, and finding the minimum area of ​​intersections. For this kind of questions, you need to draw a picture to combine the functions. Otherwise, it is very easy to just rely on imagination.

What went wrong was that after Qin Yuanqing completed the drawing, he solved the problem step by step. If it had been half a month ago, he would not have been able to solve this problem, but now it is difficult for Qin Yuanqing, but the difficulty is limited.

When Qin Yuanqing finished answering the last question, there were still ten minutes left. Qin Yuanqing saw that only one-third of the candidates were left in the classroom, and he was speechless. Are the candidates in other provinces so high? But he remembered that there were still more candidates in the same examination room.

There is Yang Xin on the Fujian provincial team, why is he not here anymore?

However, Qin Yuanqing did not hand in the paper. Instead, he checked the test paper, thought about it, and wrote another solution to the first question. This solution uses university knowledge and reduces the steps by one-third.

When Qin Yuanqing finished writing this solution, the end-of-exam bell rang. The invigilator had already asked the candidates to stop answering, and then took away the examination papers.

Qin Yuanqing left the examination room and arrived at the gathering place at the school gate. Seeing that the Fujian provincial team had all arrived, Qin Yuanqing asked curiously: "Yang Xin, why did you hand in the paper so early? You disappeared as soon as I looked up!"

"Wow~~" Yang Xin hugged Chen Xue, a girl next to her, and started crying. That was so sad.

Qin Yuanqing was puzzled. What was going on? Could it be that this test paper was too easy and Yang Xin was too excited?

But that's not the case.

"Captain, do you think everyone is as perverted as you?" Chen Xue said angrily: "Yang Xin and I only worked for half an hour and then left. Who can do such a difficult problem?"

"Yes, the questions this time were so difficult. Except for the first big question, I didn't answer all the other questions completely."

"To answer the question, I wrote a solution."

The others all spoke in frustration.

Qin Yuanqing touched his head in confusion. It's not that serious. This test paper is a bit difficult, but it's not too difficult.

"Don't be depressed, everyone. The questions in this year's league will be much more difficult than in previous years. I talked with other provincial leaders and I think this is the most difficult test paper in recent years." The vice president quickly comforted him, and then looked at Qin Yuan.

Qingdao: "Classmate Qin Yuanqing, how did you do in the exam?"

"It's okay. I've finished answering all the questions. I wrote two solutions to the first and second questions. I guess it should be fine to get a score of 140." Qin Yuanqing said honestly.

"Perverted!"

"What a bully!"

"God is unfair!"

Several other boys sighed when they heard this. They couldn't answer it. Qin Yuanqing was better, and he used two solutions, which was still life-threatening.

140 points should be fine?

Is this what people say!?

They were not even sure of a passing score of 90 points. As a result, Qin Yuanqing directly said that 140 points should be no problem, and the girls cried even more sadly. They worked so hard and were immersed in the sea of ​​questions every day, but...

The vice president was in a hurry. He had to comfort his classmates, but he was also very happy. With such a high score, he could not win the first prize.

You should know that last year in Fujian Province, no one won the first prize in the National Mathematics Competition.

As for those who finally made it to the national team, there was no one. As the vice president in charge of the competition, he almost couldn't hold his head high among his peers.

Different from previous years, this year's competition has some reforms. The first prize of the National High School Mathematics Competition final is limited to 20 people, which is 1%. The second prize is 100 people, the probability is 5%, and the third prize is 300 people, the probability is 5%.

It's 15%.

Only by winning the first prize, second prize, and third prize can you be qualified to participate in CMO.

Once you win the prize, you will basically be qualified to be recommended by the school to the university. Those who win the first prize can even get invitations from top double-first-class universities such as Shuimu University, Yan University, and Fudan University. In addition, there will be at least 10 extra points for taking the college entrance examination.

, some provinces can even add 20 points.

The vice president did not doubt Qin Yuanqing's words, because after spending half a month together, he basically understood Qin Yuanqing, it was true! Moreover, Qin Yuanqing was indeed the strongest among the Fujian provincial team.

If Qin Yuanqing really scores 140 points in this test, he may even be selected for the national team!

However, the vice-president did not ask any further questions. He took everyone to have a meal and asked everyone to have a good rest. The additional test questions in the afternoon were equally important.

Qin Yuanqing did not read a book, but listened to music to relax himself, and lay down to sleep at half past one.

At three o'clock in the afternoon, the extra test started on time.

Qin Yuanqing saw that there were only three questions in the test paper, but the answer questions had six pages, with an average of two pages per question. If he couldn't write it down, he could even ask the invigilator for extra pages.

Qin Yuanqing took a look and saw that the difficulty of the first question was comparable to the second answer question in the morning. It was obvious that the difficulty of the additional test paper this time was still higher than that in the morning.

Qin Yuanqing completed the first question and the second question smoothly, but frowned at the third question. Each of the three short questions contained knowledge from high school, but they must combine advanced mathematics, algebra, and linear algebra.

For example, the first question involves Gauss's theorem. If you don't have a deep understanding of Gauss' theorem, you can only write a solution, but you won't be able to start with anything else.

The second question is closely related to the first question. It is calculus. Calculus is also learned in high school, but it is only used in a very superficial way. It is simply impossible to solve this question with high school mathematics knowledge.

Qin Yuanqing finished answering the second question and stopped at the third question. The third question had a full 30 points, which was more than the first and second questions combined.

After thinking for a while, Qin Yuanqing began to answer. For this small question alone, Qin Yuanqing wrote four pages, with more margin than the previous ones. He just happened to write the answer in the last line, otherwise he would have to add extra pages.

At this time, there was only one minute left before the end of the exam. He took a look and realized that he was the only one left in the entire classroom.

Qin Yuanqing briefly checked his name, admission ticket, and ID card. They were correct. At this time, the bell had already rang.

"Young man, that's awesome!" The invigilator put away Qin Yuanqing's test papers and gave Qin Yuanqing a thumbs up. After everyone else in the classroom left, they stood behind Qin Yuanqing and watched Qin Yuanqing write down formulas one after another, but found that it was like

They can't understand it like reading a bible book, and they have never even seen some mathematical symbols.

They didn't know if Qin Yuanqing's answer was correct, but it gave them a very powerful feeling.
