Chapter 36 Chapter 36 Exclusive
Seeing the invigilator coming, everyone who was talking in low voices immediately quieted down. They all sat in their seats as quietly as chickens and watched the invigilator coming in.
The invigilators who came in were two middle-aged men, both of whom had very serious expressions. One of them came in and glanced at everyone in the class, and said, "Before the exam begins, I will review the exam room discipline again. No whispering, looking around, or other small movements are allowed. If I find out, you will get zero points for this exam."
"Also, if the test paper is not clear and you need a draft paper, remember to raise your hand." The man glanced at the students below with a sharp look and continued, "Also, remember to write your name on the draft paper and answer sheet, and on the test paper. If you don't write your name, this test will be invalid. Do you understand?"
"Understood." The students sitting below waiting for the exam answered in unison.
The invigilator nodded with satisfaction and opened the sealed paper in his hand.
In the quiet examination room, everyone was working on the questions silently. Even the occasional invigilator walking by could not disturb everyone's serious mood. Everyone was concentrating and checking the test questions with their pens moving quickly.
Lin Yimu was a little nervous before getting the test paper, worried that the preliminary examination paper of the competition would be so difficult that he would not be able to finish it. But now, looking at the questions on the test paper, Lin Yimu felt that he had thought too much.
Just as the math teacher said, the preliminary exam papers are basically not difficult. As long as you study hard in the training class, it is really easy to do them.
The first question was about the power function from the high school textbook. It was quite simple for the students in the training class who had classes even during the National Day holiday.
After finishing the first question, Lin Yimu had a rough idea in his mind. When he looked at the other questions, he no longer showed any surprise, but started to do the questions quickly.
Before he knew it, Lin Yimu had finished almost all the test questions, with only the last additional question left.
Looking at the last question, Lin Yimu's relaxed brows slightly frowned.
All the previous questions together only account for 110 points, and this additional question directly accounts for 40 points. This is obviously the most difficult question in the entire test paper, and it is also the question that is most likely to widen the score gap.
Lin Yimu carefully reviewed the last additional question, his brows furrowed tightly, his eyes fixed on the question in front of him, he pondered for a long time but had no clue and could not write for a long time.
The invigilator had actually noticed Lin Yimu before. Seeing him writing and stopping from time to time, with his eyes fixed on the desk, he walked over to him with a serious face and stood beside him, frowning and looking at his desk. A hint of surprise flashed in his eyes.
He noticed this student when he saw him sitting there motionless, staring at the test paper, and thought that he might have encountered a difficult problem and couldn't answer it. However, when he turned around and came back, the student had already started answering the questions at a very fast speed, and it seemed that he finished quite fast, which made the invigilator a little suspicious, so he kept paying attention to him.
When he saw the questions on his test paper, he couldn't hide the surprise in his eyes.
Only an hour had passed and the student had already finished the last additional question. Even though the previous questions were simple, this speed was too fast for a competition paper.
The invigilator stood beside Lin Yimu calmly and slowly looked at the answers on Lin Yimu's answer sheet.
Lin Yimu didn't notice the arrival of the invigilator at all. He was still concentrating on the test paper in front of him and finally started to check the calculation process on the draft paper.
While Lin Yimu was checking the test questions, another invigilator reminded him, "There is only one hour left before the exam ends. Everyone hurry up and do the questions."
The invigilator standing next to Lin Yi Mu heard the voice and shifted his gaze away from Lin Yi Mu's test paper, full of admiration for Lin Yi Mu in his heart.
This student seems to have a solid foundation and his problem-solving ideas are very novel. It's just a pity that I couldn't see him solve the last additional question in person.
You have to know that the entire test paper only has this additional question, which is specially designed to increase the difficulty of the test paper and test the students' knowledge level. It may be a bit troublesome for him as a teacher to do it.
Thinking of this, the invigilator shook his head regretfully and continued to patrol the classroom.
Not long after the invigilator left, Lin Yimu had completed the final step of the last question he was checking.
Seeing that the calculation had reached the last step and he was almost unable to move, Lin Yimu's originally relaxed brows frowned again. It was obviously going smoothly, but why couldn't the calculation continue?
This feeling was very similar to the feeling he had when he verified a mathematical conjecture before. It should have been a correct process, but he couldn't verify it no matter what. This made Lin Yimu a little anxious and irritable, and his heart beat much faster, causing a rare gloomy and irritable look to appear on his face.
Looking at the lines of calculations on the draft paper, they were clearly the correct process, but no matter how he calculated, there was no result, which made Lin Yimu really confused.
Lin Yimu wrote down a few more steps, but found that he could not calculate the result no matter what he did. This forced him to stop writing and start thinking about other ways to solve the problem.
At this time, the invigilator spoke again to remind: "There are only 40 minutes left in the exam, so hurry up if you haven't finished yet."
When Lin Yimu heard what his math teacher said, something suddenly flashed through his mind, and the gloomy and irritable look on his face disappeared completely, and turned into a happy expression. He excitedly leaned over the table, picked up a pen and started to check the calculations.
He remembered that there was a thing that he had never been able to figure out before. If he changed his thinking and applied the Riemann function, all the problems would be completely solved. Moreover, this inspiration reminded him of the mathematical conjecture that he had not solved before.
Regarding the twin prime conjecture, he had been stuck in a misconception before and had not made any progress. Today, when he heard the teacher talking about time, he suddenly thought of numbers and functions.
The Riemann function was the content of the calculus unit he had learned recently. He had not yet finished reading and thoroughly understanding the calculus unit when he was studying advanced mathematics, so he did not remember it for a while. Now that it can be used to prove, the twin prime conjecture can also be applied.
Lin Yimu was excitedly thinking about the verification process in his mind. He was obviously happy, and the verification speed of his hands was getting faster and faster.
When the final result was calculated, Lin Yimu was so happy that he wanted to stand up and jump a few times, but considering that he was taking an exam, he forced himself to hold back.
Suppressing his inner excitement and anxiety, Lin Yimu patiently and carefully checked the test paper. After making sure there were no problems, he stood up suddenly and said, "Teacher, I want to hand in the paper!"
The invigilator who had just walked to the podium turned to look at Lin Yimu in surprise. After finding out it was him, he calmed down. However, he still walked over and asked subconsciously, "Are you sure you want to hand in the paper? Don't you want to check it or take a closer look?"
Although he asked this, he was not surprised that Lin Yimu could finish the test so quickly. After all, he had just seen his answering speed and answers.
However, he was still curious about Lin Yimu's solution to the last additional question, so after Lin Yimu said he had checked the paper and handed it in directly, he couldn't wait to take it away, and took away the draft paper as well.
After handing in the test paper and packing up his stationery, Lin Yimu turned around and left the examination room in a cool manner, leaving only a thin back figure for everyone who was still struggling with the last question in the examination room, making everyone who was already anxious even more anxious.
Not long after Lin Yimu walked out of the examination room, Huang Minglei also handed in his test paper. As soon as he walked out of the examination room, he saw Lin Yimu standing in the corridor.
Lin Yimu turned around when he heard the footsteps behind him, and said with a smile in his eyes: "I knew you would come out soon."
"You are really a prophet! Why don't you go home?" He looked at Lin Yimu curiously, "Are you waiting for me?"
Lin Yimu walked towards the school gate and said, "Yes, I'm waiting for you. Do you want to go to the Yanda Library together?"
Huang Minglei quickly followed Lin Yimu's footsteps and walked out together. As he walked, he said, "Of course I have to go. I've been looking forward to this day." Then he said, "By the way, should we tell our math teachers before we go to Yan University?"
Lin Yimu shook the phone in his hand as he walked, "I've already said that."
"Good job, kid! It turns out you've been prepared for a long time!" Huang Minglei stepped forward and put his arm on Lin Yimu's shoulder. "Let's check the answers when we get to the Yanda Library. I really think they might have printed the last additional question in the wrong place. The difficulty is almost as difficult as the national competition paper."
"Hey, how did you do on the last question?" Huang Minglei asked curiously.
Unable to bear it any longer, Lin Yimu pulled Huang Minglei's arm away from his shoulders. He glanced at him and said, "Don't you know how much you weigh?" Then he continued, "I have finished the last question anyway. I used the Riemann function, but I'm not sure if it's correct."
Huang Minglei was not angry when being despised. Instead, he said, "I used it too, but I'm not very familiar with calculus, so I'm not very proficient in applying it. I might fail the exam." He then sighed deeply.
Lin Yimu heard his sigh, turned around and said with a suspicious look: "Do you think I'm easy to fool, you academic bitch."
"How can you say I'm a school bitch? If I'm a school bitch, then you're even more of a school bitch, right?" Huang Minglei retorted to Lin Yimu with an unconvinced look on his face.
Lin Yimu thought about his own actions and said with pride instead of shame: "There's nothing wrong with being a school whore. After all, not everyone can be one."
The two talked all the way to the gate of Yan University. Looking at the four large gold-plated characters "Yancheng University" on the gate, the two walked into the campus.
