Chapter 17 League Begins

After strict inspection by the invigilator, Xu Yuan successfully entered the examination room and sat in his seat.

Glancing around, I noticed that many people were wearing school uniforms.

In addition to Luyang No. 1 Middle School, which had the largest number of students, he also saw contestants from Pingzhou No. 1 Middle School in the same city. Although he did not know them, his eyes still lingered on them for a few seconds.

After all, he knew that the competition materials he used were provided by Pingzhou No. 1 Middle School.

It may be that many of the contestants are only in their second year of high school and they are visibly nervous.

Not as calm as him, a senior high school student.

Of course, the main reason is that he is confident enough, and he has experience as an associate researcher in the research institute in his previous life.

8am.

As the exam bell rang, the invigilator on the podium opened the test paper.

After receiving the test paper, Xu Yuan took a quick look and confirmed that there were fifteen multiple-choice questions.

The total time is one hundred minutes.

For ordinary students, the league test is the most difficult, but in the eyes of professional competitors, it is often easier to widen the score gap with the first test results.

Because you have to solve fifteen questions within a limited time, you cannot think too long on the questions. What is tested is your proficiency in answering questions and the solidity of your knowledge.

But this doesn't matter to Xu Yuan.

After picking up the pen and getting into the state quickly, with the help of solid basic knowledge and abilities such as numerical calculation and logical thinking, he almost did not need to use draft paper when facing the multiple-choice questions and fill-in-the-blank questions in front of him. He was able to quickly grasp the key points after reading the questions and generate problem-solving ideas in his mind.

It is no exaggeration to say that he is now like a test-taking machine.

As for the three big questions that follow, inequalities, complex numbers and sets, only the final set problem involves knowledge such as functions, straight lines, circles and equations, which is relatively complicated.

After thinking for a while and coming up with a suitable method in mind, he wrote down the answer on the paper.

Draw perpendicular bisectors and prove that fixed points inside the circle must intersect.

Finally, the set of points on the straight line is obtained.

After writing the last symbol, I looked up at the clock and found that it was just past nine o'clock.

Thinking that there was still more than half an hour before the paper was due, he couldn't help but mutter to himself.

"It only took more than 60 minutes. I should have done it more slowly."

If you hand in your paper early, you will be arranged to rest in a designated area. It is better to just sit in your seat and wait.

So I had to close my eyes and rest for the rest of the time.

After all, maintaining a high level of concentration is also a drain on the spirit.

If it were before, he might have tried to solve the problem with other ideas on the draft paper.

But now he thinks that he is using the most suitable methods, so there is no need to do it in the opposite direction several times.

As time passed, the only sound in the entire examination room was the sound of pens scratching across paper.

And uncontrolled nervous leg shaking.

Especially when there are only ten minutes left, those who still have blank questions will have their palms sweating constantly, and they can only choose to wipe them directly on their clothes to prevent getting the test paper wet.

It wasn't until the bell rang and the invigilator started collecting the papers that everyone felt relieved.

There is a twenty-minute break before the second round of the extra test. Many people will choose to go outside to breathe fresh air and adjust their condition, or quickly go to the toilet to solve physiological problems.

Even though everyone doesn't know each other, there will always be someone who takes the initiative to say hello and start a conversation.

The topic that was talked about the most was undoubtedly the exam that had just taken place.

Even though the coach had told us not to talk about these things in advance, I couldn't help it when the time came.

Although Xu Yuan did not participate, it did not stop him from listening with great interest.

"How did you do on the test, classmate?"

"I didn't have time to finish two fill-in-the-blank questions. What a pity."

"The difficulty of the questions this year is moderate. It depends on whether there will be additional questions in the future."

"At worst, I can come back next year. I came here to experience it during my freshman year of high school."

……

Soon, everyone returned to their seats as the exam was about to start. Soon, Xu Yuan finally saw the extra test paper. The exam lasted two hours and there were three big questions to answer.

Each question is worth 50 points.

As far as he could remember, he was tortured by these big questions during the competition last year.

In addition to involving more knowledge content, the question types are often complex and varied.

The proof process alone would take a long time to write.

After taking a quick look at the three questions, Xu Yuan started to work on them seriously. He used his abstract thinking ability to find the essence of the questions and determine his approach. He finished answering the first two questions in less than forty minutes.

When it came to the last question, he finally found some challenges in this league.

The whole person couldn't help but get excited.

"Finally something interesting."

With his mind active and quick, the question suddenly appeared in his sight as his eyes moved.

“由n个点和这些点之间的1条线段组成一个空间图形，其中n=q+q+1，1≥1/2q(q+1）+1，……”

“q∈N”

……

"Prove that there must be a spatial quadrilateral in the graph..."

After reading the question silently twice in his mind, Xu Yuan began to substitute the conditions in his mind to create the graph.

Unravel the problem and determine the appropriate solution.

"It's indeed a bit troublesome, but using a point set should be the most appropriate."

He murmured thoughtfully, and then he finally determined his idea and started to calculate in seconds.

"Let the set of points be V = {A, A, ...A}, ..."

……

After spending nearly half an hour, I finally finished writing the final formula and giving the proof.

Although it was the longest question in this competition, it gave me a great sense of accomplishment.

And he didn't pay attention to the panel progress bar the whole time.

If he has to rely on the panel to determine his thinking even for a league exam, then he has wasted all this time reviewing.

It is worth mentioning that this time he did not sit in his seat waiting. He put down his pen, checked his name and admission ticket number again, and then raised his hand to signal the invigilator.

"Teacher, I want to hand in my paper."

Almost at the moment he finished speaking, the others around him raised their eyes at the same time.

His face was full of astonishment.

By submitting the paper so long in advance, did he meet a big shot, or did he voluntarily give up the extra test points?

Upon hearing this, the invigilator on the podium glanced at the time, and when he found that it was just a little after eleven o'clock, he was secretly surprised and stunned.

Thinking about the several mathematics leagues I have supervised, it seems that there have never been students who submitted their papers so early.

After all, even if someone really doesn't know how to do it, they will procrastinate until the last minute.

The main theme is never give up, never abandon.

However, despite being surprised, the invigilator still led Xu Yuan to the waiting area according to the regulations.

You can leave the examination room only after the examination is over.

After handing in the paper and walking out of the classroom, Xu Yuan did not forget to look back and silently apologize to his younger classmates who were still writing furiously.

After all, his example of submitting the paper early will definitely bring psychological pressure to many people.

"I'm just training your ability to withstand pressure, so there's no need to thank me."

After finding a reason to make himself feel at ease, he completely disappeared from other people's sight.

Until the bell rang on time at twelve o'clock, marking the successful conclusion of this year's high school mathematics league.

As for the final result, naturally some people will be happy and some will be sad.
