Chapter 78 Self-disciplined academic master’s time-limited mission

Xu Yun carefully searched the memories in his mind and made sure that he had not offended Tang Yanshan in any way. After all, when he applied for the Mathematics Department of Peking University, Tang Yanshan took the initiative to invite him.

If you really have to give a reason, the source can only come from Ji Yuan Zhou Zhi.

The other party had previously made it clear that he wanted to transfer him to the Planning Academy.

But if this is the case, he is inevitably responsible for it, because he didn't make it clear to Zhou Zhi at the beginning.

Of course, it would be difficult to explain this in front of other students at this time.

We can only wait until after class to talk privately.

Having made up his mind, Xu Yun stopped thinking about it for the time being and still focused on the podium.

Soon after the names were called, Tang Yanshan put away the list and took out a stack of test papers and placed them on the podium.

"These are some basic questions I asked. I will take the opportunity to give you a proficiency test today."

"Time limit is thirty minutes."

After saying this with a calm expression, everyone below immediately started to wail.

"I have an exam right after class starts. Can I take the exam a few days later?"

"Suddenly."

"It sounds like I haven't done any questions for a while."

Listening to the students' voices, Tang Yanshan showed no intention of stopping. He threw the test paper to the boy in the first row and asked him to pass it out to everyone. With two simple words, the classroom became quiet again.

"You can sit here today. Who is not a top student in high school and is still afraid of exams?"

"Just thirty minutes."

"When the time comes to wind up, you can do as much as you can."

With Tang Yanshan's words, no one dared to complain anymore. They got the test paper and started working on it without saying a word.

As I said just now, if you can get into Jingzhou University, your math scores will not be much worse.

Even if I didn’t touch the books and do the questions throughout the summer vacation, I wouldn’t have forgotten all the knowledge.

At most it's a bit crafty.

Although I don’t know what Tang Yanshan’s move was for, no one wants to do too poorly in the exam.

Xu Yun took the test paper and put it on the table. He did not do it immediately like the others, but roughly browsed the question types of the test paper.

conic section.

derivative function.

Solid geometry.

It’s basically high school content.

Although there are not many questions, the complexity of each question is not inferior to the final question of mathematics in the college entrance examination.

He raised his gaze to look at the other people around him, and could see that many of them had serious expressions.

Even Zhou Qi next to him was no exception.

"This is much more challenging than the college entrance examination. It's just a chance to test whether your level has dropped."

Experiencing this kind of time-limited test for the first time, Xu Yun was immediately aroused with fighting spirit and full of interest. He secretly murmured in his heart that he could not care about Qian Yudong and the others immediately picked up their pens and started to answer the questions.

Although he did not review his high school mathematics knowledge during the summer vacation, he did read a lot of advanced algebra in the library.

Coupled with its own numerical calculation capabilities, manual calculation steps are rarely required.

Therefore, the speed of solving the questions is much faster than others.

In just twenty minutes, he had finished all the previous questions.

Only the last one remains.

"A is a matrix of m×n, r(A)
"Eh~"

"It's actually a system of linear equations."

When the question requirements caught his eye, Xu Yun was immediately surprised. He did not expect that Tang Yanshan also included advanced algebra in the test paper.

However, he didn't think too much. Seeing that the time was approaching half an hour, he quickly started to answer questions.

Although the efficiency of self-study may not be as good as the teacher's teaching, it is not in vain that he spent so long in the library reading books.

Try to answer no questions.

The essence of solving a system of linear equations is to transform the original system of equations with the same solution, and finally convert it into a system of equations corresponding to the simplest row echelon matrix that is extremely easy to solve.

Knowing this, Xu Yun was not slow in calculating. When Tang Yanshan asked people to start collecting the test papers, he successfully completed the last step.

But before he could breathe a sigh of relief, the panel suddenly appeared above the test paper in front of him without any warning.

Displays the secondary page of the task.

——

Mission: Self-disciplined academic master

Requirements: Study the content of this semester's mathematics major course alone. The time limit is one hundred hours. The generation of the task is regarded as the beginning of the task.

Progress: 0/100

Reward: Ability - Spatial Thinking (depending on mastery and understanding, the improvement will be up to 25%.)

Advanced tasks: Complete a thousand advanced mathematics questions in total and obtain the question-solving master achievement. 100 points will be awarded for completing the tasks, and your spatial thinking ability will be doubled.

"Is this a new advanced mission?"

Xu Yun saw the information on the panel clearly and was immediately attracted by the advanced tasks that followed.

I didn't expect that this time, two advanced tasks would be conducted concurrently.

Temporarily suppressing his excitement, he carefully studied the ordinary tasks of a top student called self-discipline.

His face also looked a little strange.

Because this is actually a time-limited mission that I have never encountered before.

The time schedule of the task has begun to move, which means that in four days, the panel will evaluate the content of the mathematics major course he has mastered this semester, and reward the degree of spatial thinking ability that can be improved based on the actual level.

He is naturally no stranger to spatial thinking, and this ability is no weaker than his previous abstract thinking.

It can help him go further on the road of mathematics.

He has dabbled in the three major mathematics courses this semester, advanced algebraic mathematical analysis and analytic geometry, in the library, but it is definitely impossible to achieve a high increase in spatial thinking ability based on this alone.

Fortunately, he now has the ability of photographic memory and can read all the contents of the book in no time.

As for the level of understanding and mastery, we can only find another way when the time comes.

After planning how to complete common tasks, a new problem also appeared in front of him.

Where can I get thousands of advanced mathematics knowledge questions?

"It seems like I need to buy a few exercise sets."

Just when he was thinking secretly, he saw the classmates who were arranged by Tang Yanshan to collect the test papers stopped in his row.

"Classmates have handed in their papers."

Hearing the sound, he suddenly came back to his senses and quickly picked up the paper and handed it to the other party.

The next second, Qian Yudong's voice rang in my ears.

"Are you done Xu Yun?"

"I barely finished it." Xu Yun nodded and answered truthfully.

As soon as he finished speaking, he saw that Qian Yudong's face was uglier than eating bitter melon, and he looked very annoyed.

"I had known that I would have read the book during the summer vacation. I found that I couldn't remember many of the questions at all."

"Me too." Zhao Yuefeng next to him also echoed.

Only Zhou Qi's face remained calm, and he finally added: "Xu Yun and I are similar, but there may be something wrong with the linear equations."

At the same time, there were also discussions in the classroom, and judging from the words and expressions, they were probably not very optimistic.

"This is not a basic question. The difficulty level is too high."

"I'm only halfway done."

"It's okay to overdo it during the summer vacation. I can't even feel the same way I did when I was doing the questions in the college entrance examination."

"Compared with the advanced mathematics content in college, this is indeed a basic question, but the linear equations at the end are a bit beyond the scope."

"What are you talking about? There's also solving a system of linear equations later, and I haven't even finished reading the questions."

Thanks to Youqin’s Siwang for the 500-point reward!
Chapter completed!
