Chapter 39 This is an impeccable test paper!

Professor Dong personally set up fractional questions. Considering the overall level of mathematics application class, 50% of the questions he gave this time are basic questions, 20% are advanced questions, and 30% are difficult questions.

It is not difficult to pass 60 points in the test, but if you want to get a high score, sorry, you can't do it.

Professor Dong personally invigilated the exam. He pushed his glasses, cleared his throat, and said,

"I took care of everyone's overall level this time, so the difficulty of the test paper is moderate. As long as you study hard, there is no reason for you to fail the subject. Don't think about cheating. If I catch cheating, just fail."

The students in the mathematics application class sat in the examination room, trembling like medieval witches who were sent to the execution platform.

The effect of Professor Dong's personal invigilation is completely different from that of other professors and lecturers.

Because many invigilators hand out the test papers, they will sit in front and read the newspaper all the time, turn a blind eye and close their eyes, and don't care what the students do below, but Professor Dong is different.

When invigilating, he likes to walk around the examination room, and likes to hang behind each student, not letting go of every detail.

In addition, he is usually very cruel, which left a psychological shadow on many students.

His score failure rate is as high as 70%, ranking among the top courses in the school.

So when he said that the test questions were of average difficulty, the students didn't want to believe a word.

The bell rang and the exam began.

Professor Dong began to wander around the examination room, like a conscientious old turtledove, looking for rotting corpses in the wilderness.

Professor Dong walked behind Bai Tongxin. Bai Tongxin shivered and shook out the prepared cheat sheet.

Professor Dong picked it up, opened the cheat sheet, and looked at it. They were all useless formulas.

Professor Dong shook his head, "I can't even cheat if I'm a scumbag."

Professor Dong let Bai Tongxin go.

Bai Tongxin recovered a small life and survived the catastrophe, but the exam papers were too unfamiliar to him, so he could only use the traditional mode of doing the questions. Three long and one short are the shortest, three short and one long are the longest, and if they are uneven, choose D .

Professor Dong walked behind the only female student in the class. The female student was trembling, and she was so frightened that she couldn't do the questions she would have done. She was racking her brains and sweating profusely.

Professor Dong shook his head, "How can you compete with male students on the same stage with such a psychological quality?" '

Professor Dong let go of the female classmate.

Professor Dong walked behind Tian Jingrui, and Tian Jingrui shivered. He couldn't do the questions he didn't know how to do now. He completely broke the illusion that he could pass the naked test. He recognized the reality and gave up on himself. Don't use the traditional mode of doing questions.

Professor Dong shook his head, "The scumbag among the scumbags missed the correct answer perfectly, and chose all the wrong answers." '

Professor Dong let Tian Jingrui go and walked behind Liu Tianming.

Liu Tianming didn't tremble. As the second best student in his class, he only wanted to surpass No.1, kill Gu Feng in seconds, trample all possible opponents under his feet, and achieve his reputation as a top student.

Liu Tianming is confident, and writes like a god. The simple questions in front made him relax his vigilance, thinking that this set of test papers is really simple, and when he solves the difficult problems, he is completely stuck, sweating profusely, scratching his ears and cheeks, and at the same time, he does not forget to block his own test papers , so as not to be plagiarized by the students around.

Professor Dong shook his head, "The basics are not bad, but if you encounter difficulties, you will be blind." '

Professor Dong let Liu Tianming go and came behind Li Ruiwen, who had the best grade in the class.

Li Ruiwen has a strong psychological quality. Not only did he not tremble, but he completely ignored Professor Dong and concentrated on solving the questions.

Professor Dong nodded, "This kid is not bad, he should be able to get a good score in the test." '

Professor Dong walked around the examination room and finally came behind Gu Feng.

He has great expectations for Gu Feng. They are all children who have submitted manuscripts to SCI. It is impossible to cheat in the exam, right?
With such a mentality, Professor Dong looked at Gu Feng's test paper.

Gu Feng's true-false questions and multiple-choice questions have all been settled, and Professor Dong glanced at his answers.

The 21-point judgment questions and the 15-point multiple-choice questions are all correct, which is good, and the foundation is very solid.

The calculation and evaluation of 10 points is good for the whole team, and the advanced knowledge has also been mastered.

Professor Dong was very satisfied with Gu Feng, so he stood behind and watched Gu Feng solve the problem.

If it was before, Gu Feng would definitely tremble like Tian Jingrui, and then forget all the questions he could do, but now, he has evolved into a fledgling-level academic master, plus he has a good relationship with Professor Dong, he will not will be affected.

Gu Feng looked at the score test paper, and each question looked like a graceful girl in light gauze, who seemed to be wearing clothes, but was actually completely naked, with a clear internal and external structure.

Each question is a beautiful girl waiting for him to explore, and they express their hearts with unique symbols.

Gu Feng is like a king of the sea, expressing that he wants this one and that one too, and he will take all these beautiful girls into his pocket and never let them go.

"It is known that the radius of a cylinder is R, passing through the diameter line of the bottom circle of the cylinder and keeping an angle of 30° with the bottom circle and cutting obliquely upward, what is the volume of the three-dimensional piece cut from the cylinder?"

Simple, take the cut diameter line as the x-axis on the bottom circle, and the center of the bottom circle as the origin to show the coordinate system, cut the solid with a plane perpendicular to the x-axis at the point passing through x, and the area of ​​the obtained right-angled triangle is..., so the Find the volume of a solid as....

"Put an isosceles triangular iron plate upright in the water (that is, the bottom is on the top), and the distance between the upper bottom and the water surface is 10 meters. It is known that the length of the triangle's base is 20 meters and the height is 10 meters. Find What is the static pressure on the triangular iron plate?"

Simple, draw an inverted triangular coordinate system, and solve the isosceles equation of the first quadrant.

This paper is not difficult for Gu Feng, 70% are basic questions, and 30% are upgrade questions to distinguish the difference between a master and a fake master.

The last proof question took a little time, but overall it is not difficult.

It took Gu Feng a total of 40 minutes to finish the test paper.

This made Professor Dong doubt life. Is the question he asked really too simple?Why can he finish it in 40 minutes?
Gu Feng checked the test paper for the last time and found that there were no loopholes before handing the test paper to the podium.

Professor Dong also walked back to the podium, and gave Gu Feng a meaningful look. He always felt that this excellent student had the potential to make his heart beat more and more recently.

He sat back in his seat, picked up Gu Feng's test paper and checked it carefully, hoping to pick out some flaws, so as to criticize him for why he handed in the test paper so long in advance with so much time! ?
Don't think that you can be proud and complacent if you have a good relationship with the professor!

Unfortunately, Professor Dong was disappointed.

Half an hour later, Professor Dong froze in place.

This is an impeccable test paper.

The problem-solving steps are clear, the thinking is clear, the calculation is accurate, and the answer is correct.

This is a perfect test paper!
Professor Dong thinks that Gu Feng is very smart and has a talent for mathematics, but he just thinks that Gu Feng can score about 89 points in the test, because the last question is beyond his outline, and it involves the knowledge points of the next semester.

But Gu Feng was completely right!
This guy has already taught himself how to score points!It must be so.

Professor Dong made a judgment.

Liu Tianming was upset at the moment, he didn't expect Gu Feng to hand in the paper so early, he obviously didn't review it, why did he finish the questions faster than me?Did you give up completely?
