"It's really killing me. Why does the Department of Mathematics have such anti-human things like monthly exams? What should I do about tomorrow's high school exams?"
On October 16, 2015, Qian Yudong held Advanced Algebra in his face in the male dormitory of Jingzhou University and sighed one after another.
According to the tradition of the Department of Mathematics at Peking University, monthly exams are set for advanced algebra, fractions, and analytic geometry.
Among them, fractions and analytic geometry are one test paper.
Two games basically took up the entire Saturday, and I don’t know how many students complained about it.
Qian Yudong didn't like mathematics at all. During the National Day holiday, he was participating in club activities and watching beautiful anchors. He hadn't reviewed advanced algebra, mathematical analysis, and analytic geometry at all. It seemed a bit incapable of him to just cram in.
"Try your best to take the exam first. This is not the final exam anyway, so there is no need to make up the exam." Zhou Qi, who was immersed in reviewing for advanced studies, stopped when he heard the sound and stood up to express relief.
Not far away, Zhao Yuefeng echoed: "I only reviewed a little bit during the holiday. I hope I can get a passing grade."
"its not right."
When Qian Yudong heard Zhao Yuefeng's words, he suddenly realized something. He raised his hand to remove Gao Dai's book from his face and turned to look over: "Didn't you go home during the vacation? When did you review Gao Dai?"
"I reviewed at home." Zhao Yuefeng replied a little embarrassed.
As the sound reached his ears, Qian Yudong was a little confused.
I'm sorry he was the only one in the dormitory who didn't review.
The source of resentment is myself.
"You are such a thief, damn it!" After coming back to his senses, he severely criticized Zhao Yuefeng's bad habit of studying secretly, and then focused on Xu Yun.
"Brother Yun."
He yelled numbly and walked towards him.
Xu Yun put down the test book in his hand and turned around, dumbfounded: "At this point, it's no longer useful to shout, so why don't you just accept your fate obediently?"
"Alas~"
"That's what you said."
After Qian Yudong heard this, he thought about it carefully and finally sighed and stopped.
But then I thought about what Tang Yanshan said before, and I couldn't help but asked curiously: "By the way, Xu Yun, are you sure about tomorrow's monthly test? Those are questions that Professor Tang will give you personally."
When Qian Yudong mentioned this matter, Xu Yun didn't know what to say.
Tang Yanshan always keeps his word, and this time the monthly exam took the time to write out the test paper separately to test his true level.
Even numerical fractions and analytic geometry were not spared.
The difficulty level of the test papers has skyrocketed.
In the past half month, in addition to reviewing English and practicing for advanced mathematics exams, he also had to upgrade the image restoration technology algorithm. For this reason, the remaining fifty hours of deep sleep time have been used up. Of course, the gains are also huge. In addition to completing half of the Hexagon Warrior mission, the image restoration technology algorithm has also been basically upgraded successfully.
On the basis of the original intelligent portrait restoration, the function of restoring other categories of images has been added.
It is believed to be sufficient to meet the upgrade needs of the city's surveillance system.
However, he was quite confident in the mathematical knowledge he had mastered. As long as Tang Yanshan's questions ranged from the freshman level, it would not be difficult to get full marks.
After thinking about it, he answered: "It should be no problem."
"I believe Xu Yun will definitely get high scores." Zhou Qi took over the conversation as soon as he finished speaking.
He often asks Xu Yun for advice on big topics. No one in the dormitory knows Xu Yun's true level better than him.
"Brother Yun studies for such a long time every day, and I'm not surprised by any grades he gets, but I'm afraid he won't have to take math courses with us in the future."
"If you say this, I will accept it."
Qian Yudong agreed very much with Zhao Yuefeng's words. He saw how much time Xu Yun spent studying every day.
I'm basically only sleeping five hours a night lately.
The key is not feeling sleepy during the day.
Although I don’t know how I persisted, my perseverance alone is worthy of admiration.
After deciding to break the pot, Qian Yudong simply gave up the practice of sharpening his gun in battle, abandoned his advanced algebra, took off his shoes, washed his feet, and climbed into bed to sleep peacefully.
Speechless all night.
The next day.
Xu Yun finished breakfast and arrived at the assigned classroom on time.
Also traveling with him was Qian Yudong.
As for Zhou Qi and Zhao Yuefeng, they were in another room.
The monthly exams of the Department of Mathematics were held randomly by several professional classes. Xu Yun came to his seat in the front row and curiously looked at the situation in the classroom before the exam officially started.
There were mostly unfamiliar faces in the entire examination room, but it could be seen that most people were nervous.
After all, it is the first professional course exam after entering university.
Even if it's not as important as the midterms and finals, I don't want to be embarrassed if I do poorly in the exam.
On the contrary, Qian Yudong's face was full of calmness, which was obviously as close as giving up on his own initiative.
As the subject leader of the mathematics department, Tang Yanshan definitely did not have time to invigilate the exam for a short period of time. Around eight o'clock, Xu Yun saw his mathematical analysis teacher walking in with the test paper. Before he even stepped to the podium, the entire classroom fell silent. Come down.
But the teacher's actions in the next few minutes made everyone confused and didn't know what was going on.
When the other party distributed the test papers, they deliberately skipped Xu Yun in the front row.
Although Xu Yun looked calm, others had never encountered such a situation before and did not answer the questions in a hurry when they got the test paper. They all turned their attention to Xu Yun and wanted to know what would happen next.
Of course, the score teacher didn't intentionally not give Xu Yun the test paper. After handing out other people's test papers, he saw him walking over again.
With a smile on his face, he took out a few pieces of draft paper from his pocket and placed them on the table in front of Xu Yun.
"This is a question that Professor Tang specially asked for you. He also said that he will personally mark the test so that you can answer the questions well."
Xu Yun reached out and opened the pieces of draft paper and found that there were handwritten titles on them.
Although there are only ten in total, it contains a lot of content and the complexity is unimaginable.
But what he is not afraid of the most is difficulties. The more challenging it is, the more interested and motivated he will be.
"Don't worry, teacher, I will try my best."
He nodded and counted the teacher's response sentences, and immediately calmed down and started to check the first question.
While he was answering the questions, other candidates in the classroom were still immersed in shock. In addition to feeling incredible, they also felt sympathy for Xu Yun.
What level of person is Tang Yanshan?
Just participating in the college entrance examination questions has made mathematics a nightmare for all candidates this year.
Now that I am taking the monthly exam in person, I can’t even imagine how abnormal the test paper will be.
This man is too miserable.
I don’t know why I offended Professor Tang and was treated specially.
There will be one more sad person after this exam.
Professor Tang's questions were so difficult that even a sophomore might not be able to get a passing grade.
With this idea in mind, everyone sighed and sighed in their hearts before gradually focusing on their own test papers.
Xu Yun doesn't care what other people think. Under the influence of concentration, he is completely immersed in these problems, and all his thinking abilities cooperate with each other to determine the ideas for solving the problems.
It has to be said that the questions Tang Yanshan asked are indeed very difficult, and the key points are different from the big questions he has done.
It's impossible to find anything similar.
In addition, each question involves several pieces of knowledge, so even he needs to be very careful.
Especially later, he suspected that Tang Yanshan deliberately increased the difficulty.
But fortunately, the content of these questions is still limited to the freshman level, and there is no situation that exceeds the outline.
As time passed by, he finally solved the last question.
"Suppose n-order matrix A=..., then |A|=..."
"Determinant?"
When the question information caught his eye, he only thought about it briefly, and then started writing about the solution process.
"Since the sum of the elements in each column of the determinant is n-1, each row can be added to the first row..."
…
It took about a few minutes to write out all the problem-solving formulas, which also marked that he successfully completed the answer sheet.
"Huh~"
"It's finally done."
I put down my pen and took a long breath, feeling extremely relaxed.
Ignoring the time, I raised my hand directly to signal to the math teacher: "Teacher, I want to hand in my paper."
There is no rule against handing in papers in advance for the monthly exams. Since he has finished the test papers, he will definitely not stay in the classroom to waste time. Besides, he has not yet completed the three-hour English study check-in task today, so he can take advantage of the opportunity to solve it. .
When Teacher Shufen heard Xu Yun's words, his first reaction was surprise.
He had read this test paper when it came. The difficulty level was much higher than the normal final exam.
He thought that even if Xu Yun had the talent to teach himself Gao Dai, he would never be able to complete it.
It is really unexpected that the paper is handed in early now.
First he raised his eyes and looked at the time, and found that it had just passed half way, and the doubts in his heart suddenly became heavier.
"Is it because you think the test paper is too difficult and you want to give up?"
When his thoughts stopped here, he walked over and said something encouraging: "There is still nearly half the time before handing in the paper, so you don't have to be too anxious."
"I've finished everything." Xu Yun stood up and replied.
"finished?"
The score teacher looked surprised and quickly picked up Xu Yun's test paper, lowered his eyes and looked at it carefully.
After confirming that Xu Yun had indeed completed the answers to all the questions, his mood fluctuated rapidly, and he finally understood why Tang Yanshan took the time to personally answer the questions for a new student.
Then his face returned to calm, he put away the test papers and said, "Remember to come on time in the afternoon to take the exams on counting fractions and analytical geometry."
"Good teacher."
Xu Yun nodded without further delay, quickly packed up his things and left the classroom with others looking up at him.
For other people in the same examination room, facing such a scene, their minds were filled with questions.
Isn’t this a question given by Professor Tang? Why was it completed so quickly?
Was it written randomly?
Or is it that Professor Tang has lowered the difficulty level?
But then he thought that he had only finished half of the ordinary test paper, and he immediately fell into silence.
Only Qian Yudong, who had not finished the third question, looked at Xu Yun's back gradually disappearing from sight, with a look of joy on his face.
"As expected of someone who came from our dormitory, he really brings glory to the dormitory."
He murmured secretly, and then continued to immerse himself in the big questions on the test paper.
In the afternoon, Xu Yun found it easier to do fractions and analytic geometry, and he also handed in the papers in advance and left.
This made his reputation begin to spread in the mathematics department. Everyone was paying attention to the final results and wanted to know how many points he could get in the test paper facing Tang Yanshan.
