Chapter 1

I almost slept on the first day of class today...even though the alarm clock rang deafeningly in the bedroom.

I have an extraordinary talent to sleep peacefully in almost any environment.

Since I was in elementary school, my mother bought me the loudest alarm clock in the world, but my brain quickly adapted. As soon as the alarm clock rang, I started to dream. I either stood on the side of the road and watched the ambulance speed to save people, or the police car whizzed past and caught bad guys, and easily integrated all kinds of noises that invaded my brain into my sleep.

Thankfully, things have improved since I went to college.

Not to mention that every time I have a similar dream, I will be alert when I really walk on the road or sit in a cinema and hear all kinds of harsh whistles.

Gradually, I can usually get up on time.

generally.

After taking a shower and eating something, I searched for the clothes I wore today in the closet.

In fact, I should have prepared last night, instead of getting up early and making a decision as I thought.

Now there is no time to iron the clothes you want to wear. Apart from T-shirts and jeans, you can only have white shirts and printed skirts.

After my last scrutiny in front of the mirror, I put on white canvas shoes and hurried out.

I also want to wear high-heeled sandals, but time is dripping and getting closer to class time. It's a long way from the apartment to the classroom, but high-heeled shoes affect the speed.

I can't be late for Donghuang Liao Hanwei's class.

I've never met this professor, but he is very famous in the department.

First, because of Donghuang's nickname, how to get it is hard to tell, and his awesome and mysterious name is confirmed.

And he is also very strict and has zero tolerance for laziness.

I think I have nothing to do with laziness, but it is definitely difficult for him to be late on the first day to convince him.

Frankly speaking, judging from the gossip I heard, Liao Hanwei is a bit annoying.

Fortunately, I only had to take one course of his this semester, and I should be able to handle one lecture every Friday... I have always been able to do it, even if it is not a particularly refreshing thing to get a high score under a disgusting professor.

I sighed secretly, you originally thought that the Political Economics of the Academy of Social Sciences would be far away from mathematics, but the fact is that when you learn to graduate level, no matter whether your major is liberal arts or science, you must understand some statistical knowledge, understand the advantages and limitations of different data collection methods, learn how to use statistical tools to analyze data, and how to make beautiful graphics, so 'data analysis and statistical inference' has become one of our compulsory credits.

I don’t know how to learn math, but I always rush to get it on the shelves, and at most I deal with homework and exams.

This course will certainly not become my favorite, in fact, the real situation is likely to be complaining.

I glanced at my phone, and my uneasy mood became stronger and stronger.

I kept cheering myself up and encouraging, and there was no reason to be nervous. 'Data analysis and statistical inference' is a public basic course, and it must be used in that huge staircase classroom. A person can easily be submerged in the vast crowd.

The teacher’s teaching is also from beginning to end, and all we need to do is listen quietly.

I quickly walked along the street to the bus stop. The graduate students also had dormitories in the school, but because I didn't like the idea of ​​sleeping together, I rented a small apartment in the residential area near the school early.

In fact, as far as I know, half of the graduate students of the Academy of Social Sciences rented houses in this community.

Walk along the street quickly to the bus stop, and the bus was not surprisingly late.

I might have gone out early, but it's too late to say this now.

I didn't spend long struggling whether to run two stops or wait for the bus, because as soon as I saw a taxi parked on the side of the road, I immediately ran up to grab the bus.

The driver was not very satisfied with me only taking two stops, but fortunately I went to school, so I didn't get off the bus because of the bad reason for the gas.

However, the driver was in a difficult situation when he drove. He followed the other cars slowly and never overtook. At least there were two traffic lights on the road. This master rushed out with the yellow light stuck and stepped on the accelerator. He even started to slow down before the yellow light was on.

I really don’t understand this type of driver. He seems so keen on making money. Shouldn’t he hurry up!

After finally getting to school, I ran to the teaching building panting at the speed of the flying man Bolt, pushed open the heavy door, and scanned the signs in the foyer indicating where I was going.

OK... there is definitely no mistake in the building. Going left is 101-124, and going right is 125-147, but what I want to go to is Classroom 155 Ah!

I looked at the watch only five minutes before class. I should have been sitting in the classroom now, or at the worst, running towards that classroom.

But in which direction do I run Ah?

My heart sank and panic followed.

This is not a good sign, I took a deep breath and forced myself to relax.

This is not the end of the world, I just need to find the classroom.

The building is here, so the classroom will not be too far away.

The accuracy rate is 55, and you don’t need a genius mathematician to know that I bet on the right.

However, the digital sign on the door ends at 147 as the foyer sign shows.

However, there is also a door at the end of the corridor - an unmarked door.

There must be another row of classrooms hidden behind this door, including No. 155!

I pushed the door open and walked in, but I didn't expect to see another hall, with some sofas scattered, not even a front desk, which was not particularly encouraging.

I walked around quickly and didn't even see a flat sign. The teachers and students were walking in the hall in a hurry, and no one stopped.

They all seem to be in a hurry and they all know which direction to go.

I stopped a student who was not so hurrying, but the man shrugged and simply said that he was new and didn't know anything about it.

Class is now officially in progress.

I walked through another corridor and found an office and knocked on the door, hoping that the teacher behind the door would help me, but the one sitting in the room was a woman with dull eyes.

Sorry, can you tell me where the 155 classroom is?This building is too big and I'm a little lost.

She frowned and looked at me dissatisfiedly. It was not here, it was the teacher's office area, and it was just coming in from the main entrance and going downstairs to the left..

Thank you, you helped a lot.I mumbled and closed the door.

I ran back to the main hall, and took a few steps to the left and saw half a floor of steps.

Hope rises, some of the nameplates on the door are for people's names and room purposes, but some are also numbered, and the numbers are not only close to 155, but also the bigger the further forward.

I finally saw the door mark 155!

I don't even want to waste time complaining about why this classroom is not on the same floor as the others and why it is hidden in the middle of a bunch of offices…I was just happy to find this classroom and was only three minutes late.

I pushed the door and walked in.

As the door behind me creaked and closed, every eye in the classroom turned to stare at me.

On the podium, Professor Liao Hanwei also interrupted his speech and calmed down.

The classroom was big and full of students, but the unfortunate thing was that I was the only one who was late.

A hot heat spread from the back of my neck. I swallowed hard with a big blushing face and walked quickly towards an empty seat in the back.

I felt Professor Liao's eyes always following me. Although I only looked at him when I entered the door, that glance was enough.

For the first time in my life, I felt that the staircase was so huge, and the aisles were endless. Every step I took felt that Professor Liao planned to use his eyes to blow me out of the solar system.

I waited for him to scold him severely, such as 'It's so bad to be late for class on the first day', 'I'm honored that you can come to class!'The sarcasm that embarrass me, but he didn't.

Professor Liao just stared at me, and his eyes were still staring at me as I sat down to face the podium.

Professor Liao started talking slowly again.

Like I said.Teacher Liao cleared his throat. Although you are all graduate first-year graduate school and mathematics is a must-take in graduate students, because you come from different colleges and majors, I don’t know your true math level.If I think your class has the appropriate ability, I will reserve the right to upgrade the textbooks.But until then, all lectures and discussions will start from the most basic.Homework and exams will also vary according to your level and requirements. Please read the syllabus carefully.

Liao Hanwei sounded scary, and it really scared me.

I glanced at the people around me secretly, each with calm faces and no tension.

My math scores for the postgraduate entrance examination were not high, and I always thought that the math level I got tested was fine to deal with credits. I began to regret following the learning experiences of those who came through the search online.

I know that many of you come here without voluntarily. Professor Liao continued: You are here today because 'data analysis and statistical inference' is a compulsory course, not out of your love for mathematics, nor to understand life, society or country through mathematics.You are here just to earn enough credits and graduate successfully.However, I need you to understand that I take this subject very seriously and will not reduce your requirements for the school's pass rate.This course is very serious and I hope you can take it as seriously as I do, otherwise your grades will be negatively affected to varying degrees.

What is the difference between this and a blatant threat!I complained secretly, but fortunately there was only one class. How bad can it be?

The result is terrible.

Professor Liao took an hour to finish the class, and when he sent us home, he handed us a fifty-page reading assignment, along with the papers that needed to be summarized for reading analysis, and a series of recommended lectures.

Mathematics textbooks seem to be the most profound subject. I spend time reading these materials repeatedly every day, but I just don’t understand.

I'm just reading, not understanding.

The week was so fast, until midnight before class, I found myself sitting at the desk staring blankly at the pages, eager for a violent sandstorm, earthquake, fire the next day... Professor Liao made it very clear that he would randomly call people to answer questions during class to ensure that each of us could complete the reading tasks he assigned.

I have a feeling that he will pay special attention to me since he was late last time.

At one o'clock in the morning, I finally gave up and fell into bed and fell asleep.
