After breakfast, as his blood sugar rose, the suppressed sleepiness surged again. Tan Jiaxuan couldn't help but yawned loudly, and then asked Yang Dejun: "Dejun, do we have classes this morning?"

”

"Yes!" Yang Dejun's answer was concise and to the point.

"What class is it?"

"It's a high number."

Tan Jiaxuan suddenly felt sleepier and couldn't open his eyes. His first reaction was to skip class and go to the dormitory to sleep? But he immediately rejected this tempting idea. It was not that he had changed his mind and his conscience found out

, but in the past month or so, he has used up the quota for skipping classes, being late, and leaving early for the entire semester. If he skips classes again, he will have to retake it!

Before leaving, my parents were very sincere and told me to study hard, stop playing around, and try to get another bachelor's degree. I was very ambitious at the time, and I promised my parents that I would never let them down. Facts have proved that determination is a good thing.

It's easy to succeed but hard to achieve. In just over a month, he once again fell into the warm embrace of games, laziness and online novels. If it weren't for various check-in requirements, he wouldn't have left the dormitory for a month!

But once it is rebuilt, things will be in trouble!

The cost of retaking courses in the school is very expensive, with one credit costing hundreds. For example, 4 credits of advanced mathematics cost one or two thousand yuan! So when the school started, a director named Su said to everyone with a smile.

:

"You are very likely to be the last junior college students in the school. In order to prepare for the 'junior college to bachelor's degree' assessment, starting from this semester, every course in the school will be taught seriously, and you must also study seriously. The next exam will not deliberately embarrass everyone.

But we won’t deliberately let things slip like before. Although the make-up exam is free, there is only one chance. The cost of retaking it is very expensive! From the school’s point of view, I hope you can pass it, and I hope you can’t pass it. So, please

Cheer up and don’t say you didn’t predict what you said when the time comes!”

Moreover, if you retake more than 3 subjects, the school will contact your parents. At that time, your image of studying hard will be gone, and your flag of trying to get an undergraduate degree will also fall. Will your parents let you drop out of school directly, and then send you to school?

Go to the factory to drive screws?!

Thinking of this, Tan Jiaxuan had no choice but to cheer up, return to the dormitory to pack up his textbooks, and went to the third teaching building with Yang Dejun.

Yes, although there are four people in a dormitory, they are not in the same class for advanced mathematics. Tan Jiaxuan and Yang Dejun are in class A2, and the other two are in class B1 and one in class B2.

There is nothing we can do about it!

For many college entrance examination students, mathematics is a difficult subject. For a test paper with a score of 150, an expert can score 140 or 50 every time, while ordinary people can only hover around 100. As for the poor students, they can score 100 or 50.

A score of 60 or 70 is a high-stakes! Private colleges are a gathering place for bad students. Take the more than 1,700 students in this year's freshman year, I dare not say that only one in a thousand can get a passing score in the college entrance examination, but I can say that it is only one in a hundred.

, there is definitely a lot of moisture!

Today's college courses are often based on the standards of the 1980s and 1990s. Those who could get into college at that time were not losers in life, but winners who successfully passed the single-plank bridge of the college entrance examination! Their IQs, their

The diligence is enough to support the teaching goal of "broad and practical, shallow and specialized" in university professional education. What now? Those who study in junior colleges are all guys who can only score 2,300 points out of a total of 750 points, and these pitiful scores

, it basically relies on Chinese (as long as you write essays conscientiously, 70 or 80 points will be no problem), English (there are many multiple choice questions, you can get 50 or 60 points even if you are ignorant), as well as mathematics, liberal arts/science comprehensive choices

The questions support it.

However, advanced mathematics is a very test of basic knowledge and IQ. It is also a public basic course for science and engineering majors. It has a lot of credits. Moreover, it starts as soon as they enter the freshman year. It is easy to drag these scumbags to death and make them lose the ability to learn.

Confidence. It is with this in mind that Xu Shengzhou organized placement tests for public basic courses such as mathematics and English after the freshmen entered school, and taught students in accordance with their aptitude according to their level differences.

Take advanced mathematics as an example. Class A1 can basically follow the original teaching plan; class A2 is a mathematics textbook imported from a beautiful country. The first dozens of pages are introductory knowledge that junior high school graduates can understand.

The difficulty is gradually increased, which is considered a transition; for classes B1 and B2, to put it bluntly, they may not be able to pass the final test paper of the first semester of high school. They can only study slowly and finally understand what calculus is, which is considered a merit.

Infinite!

Tan Jiaxuan and Yang Dejun finished swiping their "facial fingerprints" and entered the classroom. They found that the first three rows of the classroom were basically occupied by girls. Some of them were silently reviewing the content of the previous class, and some were whispering or discussing with each other.

A2 has its own class characteristics, that is, there are a high proportion of girls, and they are more diligent.

Yang Dejun was about to find a place to sit in the fourth row, but Tan Jiaxuan walked straight to the last row of the classroom, put down his schoolbag in the corner, and lay on the table like a puddle of mud: "I'm so sleepy! I want to

Get some sleep first!"

Yang Dejun hesitated for a moment, then sat down in the row in front of him: "I'll call you later in class?"

Tan Jiaxuan waved his hands feebly: "No need to call me. It was past three o'clock in the morning last night. Now my whole body is floating, my head is numb, and I can't understand. It's better to sleep for a while to regain my health."

, and listen carefully in the next class!"

It seems that you said the same thing in the last class, right? Yang Dejun wanted to complain, but he still held it back and began to silently preview the content of today's class.

Soon the class bell rang, and a young female teacher walked into the classroom. This teacher Peng is said to have a master's degree in mathematics. She just graduated from Jinling Normal University this year and joined the China Science and Technology Vocational College not long ago. This is her first formal teaching.

, I was occasionally a little nervous during class. But Yang Dejun felt that she had taught very well. Not only was she very detailed and thorough in class, but she was also very patient when answering students' questions. Unlike many teachers who only read what the teacher said in PPT.

Disappeared without a trace after class.

Teacher Peng glanced under the podium and saw the students sitting in the front row, listening intently. He also saw a few students who turned a blind eye and were playing with their mobile phones, including Tan Jiaxuan who was sleeping in the corner. But she

Without saying anything, he opened the PPT and started the class: "Students, today we are going to learn derivatives. Derivatives are also called derivative function values. They are a very important basic concept in calculus. Understanding the derivatives is equivalent to pushing away the learning of calculus.

A door. Let’s start with the concept of derivatives..."

No matter the school bell or the teacher's lecture, they did not wake up Tan Jiaxuan who was sleeping soundly behind him.

It took Teacher Peng two whole classes to finish explaining the concept of derivatives and the derivation rules of functions. She knew that this was the limit of what the students in the audience could accept. If she followed the teaching speed of her freshman teacher, she could finish the class in one

Twenty or thirty pages or a whole chapter, it is estimated that these students will be completely dizzy in the second week of school!

Whenever this happens, she is very envious of the principal, Xu Shengzhou. It is said that he can complete the basic knowledge of probability theory by himself in half a year, and then use it on the spot to learn seven or eight years at a loss. He is a probability scholar for more than ten years. He is simply inhuman!

After class, Yang Dejun packed up his books and pushed Tan Jiaxuan, who was sleeping heavily: "Lao Tan, get out of class is over!"

Maybe it was the shadow left by his teacher in high school. Tan Jiaxuan stood up reflexively and stared at the blackboard solemnly. It took him a few seconds to wake up and wipe the saliva marks from the corner of his mouth: "Oh, get out of class is over. Yeah!"

"Yes, get out of class is over." Yang Dejun still couldn't help but give a friendly reminder: "These two classes are about the concept of derivatives and the derivation rules of functions. The teacher said it is very important. In her words, the content is very thorough. Meat. I used to joke that I could no longer understand mathematics just by bending down to pick up a pen. If I don’t understand the concept and meaning of derivatives now, I won’t be able to understand advanced mathematics in the future.”

Tan Jiaxuan was a little annoyed that he didn't study hard and slept through two classes. He was also a little irritated by Yang Dejun's endless chatter. He grabbed his hair a few times and said, "I know, I know, it's really annoying!"<

/p>

Yang Dejun couldn't help being stunned and didn't speak for a long time.

Tan Jiaxuan also realized that he had said something wrong and apologized quickly: "I'm sorry, I'm not talking about you, I'm talking about high mathematics. Did you say that Newton and Leibniz were full, why did they do it?

Inventing something like calculus? Also, you said that we are a rubbish private college, why do we have to learn things like advanced mathematics? It is simply anti-human!"

Yang Dejun thought for a while: "All science and engineering majors in colleges and universities must study advanced mathematics, right?"

Tan Jiaxuan tugged at his wild hair again: "So you are against humanity! How about you tell me about today's class content?"

"Now?"

"Yeah."

"Okay! I just got a general understanding. I don't understand many things, so I can only tell you what I know. If there is anything unclear, you can ask Teacher Peng." Yang Dejun took out his textbook and notes.

, and start explaining.

After talking for more than ten minutes, Tan Jiaxuan yawned, took out his mobile phone and looked at it: "Ah, it's already past eleven o'clock. Let's go eat!"

Yang Dejun was stunned: "Then the content——"

Tan Jiaxuan scratched his head: "I'll listen to you some time next time! But I heard from the previous seniors that our school is all about dawdling, no one studies seriously at all, and they all pass the exam casually.
Chapter completed!
