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 Beijing 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 was the case, he would also be responsible for it. Why didn't he 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, naturally no one dared to complain anymore. After getting the test paper, they immersed themselves in 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 they didn’t know what Tang Yanshan’s move meant, no one wanted 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 people's expressions were beginning to look solemn.
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 check whether your level has dropped."
Experiencing this kind of time-limited question for the first time, Xu Yun was immediately aroused and full of fighting spirit. He whispered in his heart that he couldn't care less about Qian Yudong and the others immediately picked up their pens and started answering the questions.
Although he did not review high school mathematics knowledge during the summer vacation, he did read advanced algebra in the library.
Coupled with its own digital computing 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 an m×n matrix, 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.
But he didn't think too much. Seeing that the time was approaching half an hour, he quickly started to answer.
Although the efficiency of self-study may not be as good as the teacher's teaching, his time spent in the library is not in vain.
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 (The improvement will be based on the mastery and understanding, up to 25%.)
Advanced tasks: Complete a thousand advanced mathematics questions in total and obtain the achievement of question master. 100 points will be awarded for completing the task, and the 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.
Unexpectedly, this time two advanced tasks would be conducted concurrently.
After suppressing his excitement for the time being, he carefully studied the ordinary tasks of being a top student called self-discipline.
His face also looked a little strange.
Because this is actually a time-limited mission that has never been encountered before.
The current schedule of the task has begun to move forward, which means that in four days, the panel will evaluate the content of this semester's mathematics major course that he has mastered, and reward the improvement in spatial thinking ability 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 it doesn't take long to read all the contents of the book.
As for the level of understanding and mastery, we can only find another way at that time.
After planning how to complete ordinary 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 his 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 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 find the feeling of doing the questions during 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 is still solving a system of linear equations later, and I haven't even finished reading the questions."
