"It's really killing me, why is there such an anti-human thing as a monthly exam in the mathematics department, and what should I do with tomorrow's senior generation exam."

On October 16, 2015, in the men's dormitory of Jingzhou University, Qian Yudong held advanced algebra in his face and sighed one after another.

According to the tradition of the Department of Mathematics of Kyoto University, monthly exams are set for high algebra and numeracy and analytic geometry.

Fractions and analytic geometry are one paper.

The two games basically occupied the whole Saturday, and I don't know how many students complained about it.

Qian Yudong doesn't like mathematics in the first place, and during the National Day holiday, he is participating in club activities and appreciating beautiful anchors, and he hasn't reviewed advanced algebra and mathematical analysis and analytic geometry at all.

"Let's try our best to take the exam first, anyway, this is not a final exam, so there is no need to make up the exam." Zhou Qi, who was immersed in reviewing the high generation, stopped his movements and stepped forward with relief when he heard the sound.

Not far away, Zhao Yuefeng echoed: "I only reviewed a little during the holidays, I hope to get a passing score." ”

"That's not right."

When Qian Yudong heard Zhao Yuefeng's words, he suddenly realized something, raised his hand to take away the Gao Dai book on his face, and turned his head to look over: "Didn't you go home during the holidays, when is the Gao Dai to review?" ”

"I'm reviewing it at home." Zhao Yuefeng replied with some embarrassment.

As the sound came into his ears, Qian Yudong was a little confused.

He didn't review the whole dormitory.

The seed of resentment is actually myself.

"You're such a chicken thief, damn it!" After coming back to his senses, he fiercely criticized Zhao Yuefeng's bad habit of secretly studying, and then focused on Xu Yun.

"Brother Yun."

He shouted as he walked towards it.

Xu Yun put down the real question book in his hand, turned around and cried and laughed: "It's all at this time, it's not good to shout anything, or you should obediently accept your fate." ”

"Alas~"

"That's what you said."

When Qian Yudong heard this, he thought about it carefully, and finally sighed and stopped.

But then thinking of what Tang Yanshan said earlier, he couldn't help but ask curiously: "By the way, Xu Yun, are you sure about the monthly exam tomorrow, that is the question that Professor Tang personally gave you." ”

Hearing Qian Yudong mention this, Xu Yun didn't know what to say.

Tang Yanshan has always done what he says, and this monthly exam deliberately took time to test his true level and put out a separate test paper.

Not even fractions and analytic geometry were spared.

The difficulty coefficient of the test paper has skyrocketed.

In the past half a month, in addition to reviewing English in daily classes and brushing up on advanced math questions, he also has to upgrade the image restoration technology algorithm, for which the remaining 50 hours of deep sleep time have been used up. Of course, the harvest is also very huge, in addition to the hexagonal warrior mission half completed, the image restoration technology algorithm has also been basically upgraded.

On the basis of the original intelligent portrait restoration, the function of restoring other types of images has been added.

It is believed to be enough to meet the upgrade needs of the city's monitoring system.

However, he is also quite confident in his mathematical knowledge, as long as Tang Yanshan's range of questions is in the freshman stage, it is not too difficult to get a perfect score.

Turning his mind, he replied, "It should be fine." ”

"I believe Xu Yun will definitely get a high score." As soon as the words fell, Zhou Qi took over and said.

Usually, he often asks Xu Yun for advice, and 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 am not surprised by any grades, but I am afraid that he will not take mathematics major classes with us in the future."

"You say this, then I'm convinced."

Qian Yudong agrees with Zhao Yuefeng's words, and he sees Xu Yun's study time every day.

Recently, I have only slept for five hours at night.

The key is not sleepy during the day.

I don't know how to persevere, but this perseverance alone is worthy of admiration.

After deciding to break the jar, Qian Yudong simply gave up the behavior of grinding the gun in battle, dropped the advanced algebra, took off his shoes, washed his feet, and climbed into bed to sleep peacefully.

Nothing to say all night.

Following.

Xu Yun finished breakfast and arrived at the assigned classroom on time.

He was accompanied by Qian Yudong.

As for Zhou Qi and Zhao Yuefeng, they are in another room.

The monthly examination of the mathematics department was disrupted by several professional classes, Xu Yun came to his seat in the front row, and took advantage of the fact that the exam had not officially begun to look curiously at the situation in the classroom.

The entire examination room was mostly unfamiliar faces, but it could be seen that most of the people were nervous.

After all, it is the first professional course exam after entering the university.

Even if the importance is not as high as the mid-term and final term, I don't want to be embarrassed when the exam is too bad.

On the contrary, Qian Yudong's face was full of calmness, which was obviously similar to giving up on his own initiative.

Tang Yanshan, as the leader of the mathematics department, definitely didn't have time to invigilate the small monthly exam, and it was about eight o'clock Xu Yun saw his mathematical analysis teacher walk in with the test papers, and before he stepped to the podium, the whole classroom immediately fell silent.

But the next few points teacher's actions made everyone wonder, and they didn't know what was going on.

The other party deliberately skipped Xu Yun in the front row when distributing the test papers.

Although Xu Yun's face was calm, the others had never encountered this situation, so they didn't rush to answer the questions when they got the test papers, and they all turned their eyes to Xu Yun to know what would happen next.

Of course, the teacher didn't deliberately not give Xu Yun papers, but after handing out other people's test papers, I saw him come over again.

With a smile on his face, he took out a few pieces of scratch paper from his pocket and put them on the table in front of Xu Yun.

"This is a question specially given to you by Professor Tang, and he also said that he will personally read the paper so that you can answer the question well."

Xu Yun stretched out his hand to open these scratch papers, and found that there were handwritten questions on them.

Although there are only 10 courses in total, there are so many contents that the complexity is unimaginable.

But the last thing he is afraid of is difficulties, the more challenging he is, the more interesting and motivated he can be.

"Don't worry, teacher, I'll do my best."

Nodding his head, the teacher responded to the sentence, and immediately calmed down and began to check the first question.

And when he answered the question, the other candidates in the classroom were still immersed in the shock just now, in addition to feeling incredible, it was more of a sympathy for Xu Yun.

What level of character is Tang Yanshan.

Just participating in the college entrance examination has made mathematics a nightmare for all candidates this year.

Now that I personally propose the monthly exam, I can't imagine how perverted the test paper will be.

This man is too miserable.

I don't know how to offend Professor Tang, but I was actually treated specially.

After this exam, there will be one more sad person.

Professor Tang's question, this difficulty is probably not even able to get a passing score when the sophomore seniors come.

With this kind of thought, everyone sighed a few words in their hearts before gradually putting their minds on their test papers.

Xu Yun doesn't care what other people think, under the effect of concentration, the whole person is completely immersed in these problems, and various thinking abilities cooperate with each other to determine the solution ideas.

I have to say that the difficulty coefficient of Tang Yanshan's questions is really high, and the key is not the same as the big questions he has done.

It's impossible to find anything like it.

In addition, there are several knowledge involved in each question, and Rao also needs to be very attentive.

Especially after that, he suspected that Tang Yanshan was deliberately increasing the difficulty.

But fortunately, the content of these questions is still limited to the freshman stage, and there is no overclass.

As the time passed, he finally solved the last question.

"Let the nth order matrix A=......, then |A|=……”

"Determinant?"

When the information about the question came to his eye, he only thought about it for a short time, and then began to write down the process of solving the problem.

"Since the sum of the elements in each column of the determinant is n-1, you can add each row to the first row......"

……

It took him about a few minutes to finish all the formulas, which also marked the successful completion of the answer sheet.

"Whew~"

"It's finally done."

Putting down the pen and exhaling, the whole person only felt extremely relaxed.

didn't care about looking at the time, and directly raised his hand to signal to the teacher: "Teacher, I want to hand in the papers." ”

There is no such thing as not being allowed to hand in the paper in advance for the monthly exam, since the test paper has been completed, he will definitely not continue to stay in the classroom and waste time, not to mention that he has not completed the three-hour English study check-in task today, and he can just take the opportunity to solve it.

When the teacher heard Xu Yun's words, his first reaction was to be surprised.

When he came, he read this test paper, and the difficulty coefficient was much higher than that of the normal final exam.

He thought that even if Xu Yun had the talent to teach himself Gao Dai, it would be absolutely impossible to finish it.

It is really unexpected that the paper is submitted ahead of schedule.

I first raised my eyes and looked at the time, and found that it was just half over, and the doubts in my heart suddenly became a little heavier.

"Do you think the exam paper is too difficult and plan to give up?"

The thought stopped here, and he walked over and encouraged: "There is still nearly half of the time before the paper is handed in, so you don't have to be in a hurry." ”

"I've done it all." Xu Yun stood up and replied.

"Done?"

Teacher Shufen's face was full of surprise, and he quickly picked up Xu Yun's test paper and lowered his gaze to examine it carefully.

After making sure that Xu Yun had indeed completed the answers to all the questions, while his mood fluctuated rapidly, he finally understood why Tang Yanshan deliberately took the time to personally write a question for a freshman.

Immediately, his face returned to calm, and he put away the test paper and instructed: "Remember to come over on time in the afternoon to take the test of counting and analytic geometry." ”

"Good teacher."

Xu Yun nodded, didn't delay too much, and quickly packed up his things and left the classroom under the gaze of others.

For others in the same examination room, their minds were suddenly full of question marks in the face of such a scene.

Isn't this Professor Tang's question, how did he finish it so quickly?

Is it scribbled?

Or did Professor Tang tone down the difficulty?

But when I thought that I was only halfway through even the ordinary test papers, I immediately fell silent.

Only Qian Yudong, who had not finished the third question, looked at Xu Yun's back that gradually disappeared from sight, and his face was full of joy and joy.

"It is worthy of the people who came out of our dormitory, and they really bring glory to the dormitory."

muttered to himself, and then continued to bury his head in the big questions on the test paper.

In the afternoon, Xu Yun made it easier to do the counting and analytic geometry, and he also handed in the papers in advance and left.

This made his reputation also begin to spread in the mathematics department, and everyone was paying attention to the final results, wondering how many points he could score in the face of Tang Yanshan's test paper.
