Linhai University, Teaching Block 4, Room 201.
On the podium.
An old professor with black-rimmed glasses was emphasizing the rules of the examination hall.
"Students, although this is not the beginning of the semester, I still have to emphasize the rules of the examination hall. One: No whispering, and no talking during exams. Two: No plagiarism, no plagiarism, no plagiarism. 3. You are not allowed to go to the toilet during the exam without special reasons."
After drinking the wolfberries tea in the thermos cup, the old professor continued,"I know that some students have prepared small notes and are hoping to have a chance to take a look. I advise these students to give up on this idea.”
Li Xiongfei, who was sitting in front of Gu Bai, immediately clamped his legs together when he heard the old professor's words.
Some of the other students who were preparing small notes also felt their hearts racing.
"Your sister…Why are you so strict!"
Some students complained softly.
Obviously, the invigilator on the podium had given them enough pressure.
Gu Bai smiled indifferently.
His results were already passable, and now that he had the system's mathematics lvl 4 boost, he just treated this exam as a game.
He stretched lazily and waited for the students in front of him to pass the test papers over.
"It's too difficult. There's definitely something fishy about this exam.”Li Xiong Fei, who was sitting in the front row, passed the test paper to Gu Bai and complained in a low voice.
After receiving the test paper from Li Xiongfei, Gu Bai wrote down his student number, name, and class. He casually glanced at the questions and was a little puzzled.
Was the test paper difficult?
He couldn't tell.
Then, Gu Bai picked up a black pen and started writing quickly.
He would only know if it was difficult or not after he wrote it.
The first type of questions on the test paper were multiple-choice questions. The first sub-question was a typical function f (x) im finding the limit. The result was obviously B when x went to infinity and x went to 0.
For the second question, there was no need to calculate the criteria.
The third question was about the spatial coordinate system. Gu Bai thought about it for a while and chose C.
As for the fourth question, it was a simple function calculation. It was purely a free question. Using draft paper was disrespectful to these two questions.
The last question of the multiple-choice question was a little tricky. Let 0=z=1 on the surface x2 y2=R2 (R0). The value of e x2 y2sin (x2 y2) ds.
em.......
Gu Bai thought for a moment and had an answer in his heart.
This question looked quite scary, but it was actually a combination of space curved surfaces and equations. As long as one grasped some methods to solve the equations of space curves, the final step was nothing more than calculation.
Wasn't this level of equation calculation done with hands?
"I guess Li Xiong Fei was mistaken. The test paper wasn't that difficult.”
"Or perhaps it's rare that they're all behind.”
Gu Bai did not dare to be careless. After finishing the multiple-choice questions, he began to rub his hands together and prepare to solve the questions at the back.
however
The difficulty of the next question…Gu Bai was stunned. He did the last question without any hiccups.
"This is the difficulty?"
Gu Bai thought to himself suspiciously. After filling in the last question, Gu Bai looked left and right. He was really afraid that he had taken the wrong paper.
"Don't whisper."
However, at this moment, the professor on the podium coughed and reminded Gu Bai, giving him a fright.
He wasn't planning to plagiarize. He was just wondering if he had taken the wrong paper.
After waiting for a while, Gu Bai thought about it and decided not to care. It was not his responsibility to give out the wrong test papers.
Fortunately, Gu Bai took the test paper and walked towards the podium to hand it in.
"I don't want to think about it anymore.”Seeing Gu Bai hand in his paper, the old professor who was sitting at the side pushed up his black-rimmed glasses and asked with dissatisfaction.
"Don't think about it." Gu Bai paused for a moment. He wanted to ask the professor if he had taken the wrong easy test paper, but he gave up after seeing his attitude.
As for the inspection, there was no need.
If he still needed to check this question, then…Gu Bai might as well kill himself.
"Okay, go ahead." Hearing Gu Bai's answer, the old professor shook his head in disappointment.
"Oh." Gu Bai placed the test papers neatly on the desk of the podium and left with his schoolbag.
Before the exam, Gu Bai received a message from Senior Wu Hai, saying that he would go back to school today to read his graduation thesis.
Gu Bai took this opportunity to look for Senior Wu Hai and collect the 800 yuan for his hard work.
"Sigh…" Seeing Gu Bai leave, the old professor sighed and reminded the students who were still taking the exam."This time, because the exam papers were taken from the Mathematics Department, the difficulty is indeed a little higher, but…The students could not give up just like that.”
"There are still 100 minutes before the exam. It's a pity to give up like this, right?”
The last question was deliberately said for the students in the class who were still writing their papers to hear.
The old professor slowly stood up and placed the thermos flask in his hand on the podium.
Suddenly, the lonely paper on the podium, filled with answers, stunned him.
He actually finished it?
It had only been 20 minutes since the exam.
The old professor picked up Gu Bai's test paper and began to read it.
"BDCDA, it's so rare that it's not written randomly. All the multiple-choice questions are correct.”
The old professor was a little surprised. Because he was the one who set the test paper, he knew the answer very well.
Without stopping, he continued to read the fill-in-the-blank questions.
The first question (-2 Pi, 2) was correct.
He also got the second question right.
The third question…
As the old professor looked down, the expression on his face changed from suspicion to surprise, and finally to a touch of shock.
He did not expect that this paper was actually a full score paper.
He wouldn't be so surprised if it was just a full score paper. Most importantly, this paper was completed by the student in 20 minutes.
He scored full marks in 20 minutes?
This was…Even some mathematics graduate students couldn't do it.
" Interesting, really interesting."
"A non-mathematics student can have such talent.”
The old professor couldn't help but smile. He hadn't seen such a genius for many years.
As for Gu Bai cheating, he could completely rule out that possibility.
Firstly, it was because he had personally invigilated the exam, and secondly, it was because he had personally printed the exam paper this morning.
After reading the questions, the old professor looked at the name column.
Name: Gu Bai
Student ID: **
Major: Nonwoven Materials and Engineering
"Gu Bai, not a bad name."
"I'll remember you."
The old professor's face revealed a strong interest.
