"Tongtong, can you try your best to get into Class A for the high-mathematics exam this afternoon?"
The midday sun shines through the floor-to-ceiling windows of the dining hall, and shines lightly and softly on the white dining table.
After Chen Mo put down his mobile phone, he crossed his hands and put them on his chin, resting his elbows on the table. He looked at his girlfriend, who pushed up her glasses from time to time and was studying seriously under the extremely clean lemon yellow light, with love in her eyes.
and pampering.
After a while, he smiled brightly and asked softly.
"ah?"
Bai Yitong was mechanically putting slices of cantaloupe into his mouth, his eyes always staring at the exercise book in his other hand. At this moment, he raised his head in surprise when he heard this, and his glasses fell to the tip of his nose.
The big eyes flicker, making the picture look silly and funny yet cute (*?▽?*).
"Hahaha."
Chen Mo looked at it and chuckled, raised his hand to straighten his girlfriend's glasses, crossed his index and middle fingers, and lightly flicked his girlfriend's smooth and plump forehead.
"I said, take the exam well in the afternoon and go to Class A."
He leaned his head closer, his light-colored eyes were like gentle water, reflecting the appearance of his girlfriend, and repeated in a low voice and seriously.
"Well——"
Bai Yitong's eyes were still in a trance, not switching from the layers of high-numbered letters and formulas. After reacting, his pupils refocused in front of him, and he saw the serious and gentle eyes of Chen Mo who were very close. He didn't know why,
His face turned a light pink again. He really nodded at Chen Momo.
"Um!"
"I will work hard! Although I don't have confidence, but I said this to Ah Mo, I will work hard and I will definitely get into Class A!"
Bai Yitong didn't even ask why. After Chen Mo told her, she nodded and agreed without hesitation. She knew how difficult it was, but this was the first time Chen Mo asked her, and she would definitely do it no matter what.
!
Chen Mo smiled in surprise and looked at his girlfriend, feeling that she looked silly.
"Don't you want to ask why?" He looked at his girlfriend and said with a smile.
"Don't ask. If you have anything to ask, Ah Mo must be doing it for my own good."
"Hahaha, do I have such a good image in Tongtong's heart? I'm not that good. In fact, I also have selfish motives..." Chen Mo looked at Bai Yitong and said softly in the last sentence.
Seeing the little silly girl pushing up her glasses and lowering her head to read the question, Chen Mo was filled with smiles.
"Come on, bring me the questions, and I'll take you through it temporarily."
…
After dinner in the afternoon, Chen Mo sent Bai Yitong into the classroom of the business school.
After watching Bai Yitong go in and sit down at the back door, his eyes were still staring at the draft book, and his hands were wiping sweat on each other slightly, and he smiled.
He did not tell Bai Yitong that he and Teacher Liang had to get the exam quota and would take the exam with her this time.
I didn't choose to sit with her and make her feel nervous.
When the exam was about to begin, when all the exam students in the lecture theater were about the same size, Chen Mo found a seat in the back row. Seeing Bai Yitong's back in front of him, he smiled softly and sat down casually.
The bell rings.
"Students all know that we are just a temporary placement test now. There is a placement test, which I won't go into. Everyone must have received the notice. Please relax, the test paper is not difficult, it is just a test and you have to be careful.
and patience. This exam will not be counted in subject scores and grade points, so just take it with confidence."
The teacher on the podium is a man who looks to be under forty years old, but already has Mediterranean tendencies. His exposed scalp exudes the light of wisdom under the light. At this time, he is looking at the microphone and sitting in the lecture theater.
The standing student said with a smile.
Considering that the students have not been exposed to advanced mathematics, Professor Li, his doctoral supervisor, was really kind when he asked them to write questions this time. They are basically variations and extensions of high school mathematics. The questions are very suitable for this group of people who can pass the A-level exams.
For a talented person, if you have a solid foundation and work hard, you can still get 60 points in the exam.
I tried my best to ensure that the students still have the last bit of dignity after the exam, so that their mentality will not completely collapse.
As for taking the test above 80%, or even above 85%, it is very difficult. For questions beyond 60%, they have found some very "interesting" questions, and they must increase the sourness to a certain level.
Let the junior students also feel the beauty of mathematics, just like they were tortured to death by Teacher Li, bah, kindly taken care of.
Of course, as for the perfect score, Lu Ming never thought that only a top-notch genius could solve their problems. It would be enough to get a score of 88, because the last 12-point question was written by their teacher Li himself.
out.
He glanced at it while taking the paper.
Hiss, that sour feeling was exactly the same as when they were tortured when they were graduate students. That was simply not a calculation amount that could be calculated in one class.
Teacher Li put down his words. Basically, if this paper can reach 80, Class A will be stable.
But now he is right when he says that the paper is easy. The first 60 points that are easy are really easy. The later parts that are difficult are difficult, so there is no conflict~
Thinking of this, the smile on Lu Ming's face deepened and he squinted his eyes harder. I hope these students who are used to taking exams of 90 and 100 will not cry in this exam~
"Oh, yes, and more! We have no exam time requirements, and there is no requirement to hand in papers half an hour before the end of the exam. As long as you finish writing, you can hand in the papers directly.
Regardless of whether you can't write well or have finished writing in advance, you can submit the paper in advance. I just decided to teach you in advance. This class lasts for four hours. It will be taught right after the exam, so you don't have to wait.
Already."
"Okay, teacher!"
Very good, very motivated! Please keep it up!
After Lu Ming said this, he stopped talking nonsense. Hearing the confident answers from the lower class students, he smiled even more happily and asked for help to hand out the papers directly.
For the placement test at the beginning of school, maybe there was a thought that if there were too many papers, it would block the scratch paper, so there were quite a lot of papers given.
After the teacher handed out to the person in front of Chen Mo, there was more than enough, so he generously gave Chen Mo several sheets, saying that one sheet was for making, and the other sheets were welcome, and could be used for drafting. He also turned to the students and asked if anyone wanted them.
Use the extra papers as scratch paper.
It made Chen Mo twitch his mouth.
"Everyone can start, you're welcome~"
Lu Ming raised his hand and said.
Everyone was very excited when they got the paper.
There are many people hiding in places like A University. Sports aside, when it comes to brains, students at A University have never been afraid of anyone. A University has never been short of brains, even perverted people.
They were disappointed when they heard Lu Ming say that the test paper was not difficult. The test paper was not difficult, so how could they widen the gap?
But until the moment they saw the test paper, some students finally stopped thinking so. They finally understood the sinister intentions behind the smiling face of the teacher who was looking at them on the podium.
It’s so heartbreaking! It’s so heartbreaking!
Especially when they saw the difficult problem at the end, most of the students burst into tears.
Only a few people showed excitement and interest.
Fang Quan is one of the few people who picked up the paper and was interested in the questions at the end. He knows Professor Li Jianan and worked with his team during the summer camp. He has some experience with his question-writing style and research direction.
I have a lot of understanding. When I saw these questions, I could tell at a glance that they were written by Professor Li, and there was a sense of familiarity and intimacy.
But Professor Li was so ruthless that he tested students on the topic they were studying. Even he was stunned for a long time when he saw the difficulty and calculation amount of the last question.
Thinking of something, before laying down the paper and writing, Fang Quan turned his head and glanced at Bai Yitong. Seeing that she looked shocked and frightened, he snorted lightly, feeling secretly happy. He pushed up his black-rimmed glasses.
After clicking his tongue, he turned his head with a chuckle and started writing.
The difficulty of this test paper is really God helping him.
He didn't know if there were any other powerful people in this exam, but he was confident that he would be one of the first few to finish writing and handing in the paper. Being first would be the best, and Bai Yitong happened to be sitting in the first row close to the teacher.
On the podium, when he handed in the paper in advance, he would pass by her in a swaggering way while she was immersed in writing and unable to write, and then hand in the paper.
Let her know that her boyfriend from the art school really only has a good-looking face and can't help at all when it comes to serious matters.
…
But he didn't know that Bai Yitong was really shocked, but what shocked her was that she actually knew the previous sixty-point questions, which Chen Mo had taken her to review last night. She actually had some ideas for the later big questions,
Chen Mo took her to review it at noon today.
Her Amo is really awesome.
Bai Yitong was surprised and happy! If her hair hadn't been tied up and there were no loose hairs falling down, her hair would have stood up.
She glanced at the closed front door of the amphitheater, where Chen Mo had sent her in before. Her eyes were full of excitement and feeling. She withdrew her eyes, pulled out the pen cap, and started writing like a warrior with a sharp blade, writing furiously.
…
Chen Mo glanced at Bai Yitong and saw her starting to write. Then he habitually turned the black pen and glanced at the paper before starting to write.
He is not excited. The difficulty of this question is not enough to make him excited.
Unlike when he was giving lectures to Bai Yitong, Chen Mo was very fast at reading and answering questions. As Bai Yitong said, Chen Mo did a lot of calculations in his head and got direct results. Many of the simple fill-in-the-blank questions on the test papers were
, there was no calculation process at all, Chen Mo just wrote the results directly on the answer sheet.
If the amount of calculation is relatively large, Chen Mo will at most write an extra number next to the question in the test paper as an aid and transition for mental arithmetic.
Just like what Teacher Liang Rui said, the questions in the placement test were indeed not difficult for Chen Mo. When he finished writing and there was only one big question left, the minute hand barely moved for less than a quarter of an hour.
Fortunately, Chen Mo was sitting in the last row, in an inconspicuous position, otherwise the people sitting next to him might have been overwhelmed by his rolling voice.
Fortunately, there was no one beside Chen Mo. The brother sitting in front couldn't look back. Although he heard Chen Mo turning the paper quickly, he didn't hear the sound of the signature pen rustling against the paper. He thought that the brother behind him didn't write either.
To some extent, it was just because I didn’t know how to write and I looked back at the paper, so I wasn’t too nervous.
Sighing softly, it is better not to be impatient when things happen.
The little brother even felt a lot more at ease, feeling that he was at least better than the guy behind him. Although he wrote slowly, he walked back step by step in a down-to-earth manner, glancing at the words filled with words.
Two pieces of draft paper were filled with formulas and calculation processes, which gave me a great sense of accomplishment. So I smiled and continued writing.
Chen Mo did indeed write a few words as he heard at the front desk. Apart from the answers, he basically did not write any extra words. Even the big questions at the back only left the calculations and results of the most important steps.
.Concise and save ink.
Chen Mo, who had already seen the last question, quickly read through the overly long questions and conditions.
He raised his eyebrows slightly.
The last topic was really familiar to him. The mathematical model analysis of using orthogonal functions to solve fiber optic gyroscope errors, and the digital-analog analysis of optical fiber were so familiar that he couldn't be more familiar with it.
He finally understood that Teacher Liang Rui said that he and Professor Li who had written the test were familiar with each other, so much so that they collaborated on a project. Teacher Liang Rui must have often asked Professor Li to help him calculate experimental data. Look at what happened.
Each placement test paper also contains content related to optical fiber.
Chen Mo tugged at the corners of his lips helplessly.
The last question was not difficult for Chen Mo, who had already calculated countless questions of this type, but the calculation amount was a bit heavy and there was a lot to write.
The space on the answer sheet of this test paper is actually endless.
So Chen Mo simply indulged himself in following the thinking pattern, skipping complicated calculations, and only picked up the important key steps and wrote:
Constrained parameters and mathematical modeling of fiber optic gyroscope measurements
1.1 Constraint parameters of fiber optic gyroscope measurement
In order to solve the fiber optic gyroscope error, we first analyze the constrained parameter model of fiber optic gyroscope measurement, use parameter optimization and binary differential parameter fusion methods to control the process of fiber optic gyroscope error measurement, and use binary differential equations to establish the constrained parameters of fiber optic gyroscope error measurement.
Distribution model, combined with the binary multi-beam solution method...analyze the connection functional of the fiber optic gyro error map f on i×r×r→r...where, u:i×ird→ir is the real value of the fiber optic gyro error distribution
Function, d≥4... Obtain the binary combination function of fiber optic gyroscope error distribution as...
2.2 Mathematical model of fiber optic gyroscope measurement
…
Just skipping steps like this, Chen Mo also wrote nearly a whole page of paper with thousands of words in a eloquent manner. He wrote very fast, even thinking about mental arithmetic. When he finished writing the last question, it took nearly half of the time.
After an hour, when he finished writing the last line of words, a gel pen he bought on the charity shelf of the self-service shopping was completely out of water. At the last period, Chen Mo could only click a dot instead.
