It's all in vain for a long time.

Wen Xiaoguang decided to give up on this strange woman. Everyone has their own strengths, and her strengths are not in the brain.

In the future, I can only carry it alone, without a team, and I don't fantasize about cooperating.

Study, I'll come, you spread out.

Make money, I'll come, and you will scatter.

Before going to bed, he was firm in his thoughts.

There was no one in the night, and there was no sound.

Until the eastern sun shines on the earth, the coolness of the night slowly withdraws from this county.

The first street lights go out, the first pedestrian appears,

A new day in Xianzhou began here.

Wen Xiaoguang's day began with the noise of 120 ambulances coming from nowhere.

He tried to understand the family's feelings, but refused to be kidnapped by morality, saying that he was really unhappy to be woken up.

Wen Xiaoxiao didn't have to get up so early, otherwise the girl would have worked too hard.

As for breakfast, in such a small county, ten years ago, 5 cents was enough to buy a bun, and one dollar was enough to buy a cup of soy milk, which was completely sufficient.

Wen Xiaoguang thinks this is very good.

But last night, Wen Xiaoxiao didn't agree at first, and he had to say that he was no different from telling the truth now!

And what do you say, 'Two dollars is enough for an hour of Internet access'!

And it's not just a matter of surfing the Internet, her brother may not have breakfast!!

This thinking logic is just!

Wen Xiaoguang does not deny that there are indeed some people who don't know what to think about saving money to go online, but this kind of unforced thing can't happen to him.

Besides, the flags are all set.

So when school was out at noon, Wen Xiaoguang, who stayed at school for dinner, escaped the clutches.

He borrowed the money from the scrap letter and walked along the political and legal road at the school gate for five minutes until he reached an alley, turned right,

Walked into the Internet café.

This place is named Times Internet Café, with white characters on a red background, erected at the door, and the embarrassing thing is that most of the strokes of the word 'bar' are bad.

Lifting the plastic curtain at the door, on the right hand side is a young lady who kills Matt eating melon seeds.

"There's an empty plane, right?"

After the young lady raised her eyes, her sloppy eyes instantly condensed, and her whole heart trembled, staring at a certain part, "Yes, go up to the second floor, I'll take you there." ”

Wen Xiaoguang was a little strange, "No, just tell me what time it is." ”

It made her feel bad to be rejected outright, and the key was that she wanted to be ladylike, so she said, "That'...... It's the number 53, it's easy to use. ”

There is nothing particularly complicated, and the school uniform on his body is ignored, if someone asks, you can say that you forgot to bring your ID card.

The environment of the Internet café is not very good, the toilet at the staircase smells very strong, the six or seven rows of seats on the first floor are smoky, and the children wearing headphones sit in rows, except for the screen, everything outside has nothing to do with him.

Open the Baidu webpage and search for the Jiangnan University of Technology Postgraduate Examination Forum, he is not looking for many things today, only 8-10 past postgraduate examination questions of the major he studied before rebirth.

What's the use?

Naturally, it's about making money.

Last night, Wen Xiaoxiao gave him the inspiration of this: the real questions of the postgraduate entrance examination.

As a top student, I can probably only think of this,

After careful analysis, I feel that it is more feasible.

First of all, the real question + answer is pretty much the same: the workload is not that big.

And there are examples: when he was in graduate school, his classmates did this, and he made a small profit, and he understood the process.

Maybe there is a lack of practical experience, but the thing itself is not difficult, and it will not be empty, even if it fails, it will not be like other start-ups to owe a lot of debt.

Because the so-called cost is nothing more than printing and courier fees.

The core value of this part of knowledge is in his mind.

So how does this thing make money?

This is related to the graduate school entrance examination.

Generally speaking, there are four courses in the engineering postgraduate examination, advanced mathematics, professional courses (150 points each), and politics and English (100 points each).

Except for the three major courses, they are all unified, and there is only the difference between the first and second in the test and the English one and the English two.

From the perspective of the market, the commonality is large, the users are many, and the demand is homogeneous, so enterprises (postgraduate institutions) are willing to provide unified products (learning materials).

The trouble is the rest of the problem.

Because the professional course is the question of each school itself,

That is, there are N real questions in N schools, and there are hundreds of colleges and universities with master's degrees in the country, each containing an unknown number of professional categories.

This diversity means that there will never be an institution that will provide thousands of complete sets of past papers, so how many people will have to recruit and how much money will it cost?

Of course, you can also have this service for money, which is a private customization class, for example, if you pay 20,000 yuan, no problem, just for you, the undergraduate final exam papers of that university will be found out for you.

Either you go and search the Internet yourself.

In addition, even for the same major, different colleges and universities will have different questions, which involves raising and pressing the scores of professional courses.

It's easy to understand, for example, computer science, you can go out of the second school simply, just like looking for a partner, the ugliness is still demanding, who goes?

985 colleges and universities have difficulties, because there are many people who want to go to her.

In fact, in this case, wouldn't it be easier for colleges and universities to publish their own learning materials for the convenience of candidates?

Answer: Think beautifully.

Transparent you ghost, your family introduced people will all strip naked to show you?

They only told you to refer to such and such a book, and then they didn't even talk about this information.

So the question is, how do you know what kind of questions your target institution is going to have?

How difficult is it?

What question type?

You don't even know a few questions.

Don't say it doesn't matter, you go and try, you know everything in the college entrance examination and it's not like you are like.

And please note that 150 points in the professional class is not a trivial matter.

So there is a saying that half of the success of the graduate school entrance examination is studying, and the other half is collecting information. These preliminary preparations are essential, and it really takes a lot of effort, don't be stupid.

People said that they recruited 8, but it turned out that 7 were escorted students, so you have the ability to take the test.

Past papers are crucial in this information.

You don't see that the relevant forums are full of "asking for 625xx planning professional questions",

"Ask for past questions of xx university xx majors, paid!"

The smarter ones can be written: Seniors study notes!

His roommate had such an experience as soon as he was in graduate school, not only did he give the information to the 'difficult schoolgirl', but he also transferred money to others, bought a mobile phone, and didn't want to be happy every day.

Life is very happy, and I was a little sorry to know that it was a man.

By extension, it is another tragicomic novel.

This also shows from the side that those materials are not easy to find, otherwise which big man is willing to coax another big man to pick his feet every day, and it's not a real gay, it shouldn't be.

Therefore, there is no standardized channel to buy, you can only scrape together some things from the Internet, and you can't buy them if you can't find them, but the credibility of a certain Tao is limited.

He will give you a set of questions, marked with the 2007 real questions of xx university xx major, which is a small waste of money and a big delay in the postgraduate examination.

The truth and falsity of information on the Internet are one and the same thing.

In addition, there is the problem of information fragmentation.

As a result, in most cases, you either miss the past papers of the year or the answers to that question, or you are going to take the A university exam with the past questions of B University in your hand.

Or maybe you got the question right, but the answer given to you is wrong, sometimes it's the person who sells it with a sharp Crtl+C to Crtl+V operation, sometimes he thinks it's right, and sometimes, you can't see that the answer is wrong.

The most exciting thing is that it happens that you find that the answer in the exam room doesn't seem to be right, but you can't say what's wrong, but time doesn't allow you to think about it, and then look at the score, this question is 25 points!

Wow, that tangle in the continuous turn,

Do you feel that the tension from head to toe, trembling and the double torture of body and soul are full of excitement that makes people obsessed with it and can't extricate themselves!

It's so fucking cool!

In fact, the answer to the question from unknown sources is very doubtful.

Wen Xiaoguang is a major in urban transportation, but all science and engineering majors must make requirements for mathematical models and optimization algorithms, his alma mater is awesome, the teacher's nostrils are facing the sky when the teacher asks questions, and the topic of optimization theory is put out, and those who can do it stay, and those with low IQ go.

In other words, those questions are not easy.

The most terrible thing is that there are open questions, there are no standard answers, but it is very important to test your attention and understanding of the research frontier of this major, especially to have your own thinking, the thinking here is not just a random idea, you must be logical and self-consistent.

For example, what do you think about urban traffic congestion?

A lot of people will say, I will. Then write the set you see in the media, list the questions one by one, what about journalism and communication?

Get something that everyone knows and put it up, you really don't watch the news when you are a teacher, right?

You must know that according to the development process, our current urban problems have been experienced abroad 30 years ago, so what you are talking about may be the views and formulations of a paper 30 years ago.

What do you mean?

Do you want to say...... Scholars in recent years include mentors from this school, who have followed up on their research...... It's all rubbish without reference?

If you rise to a height, avoid the real and make up the number of words, and want to show that you think a lot, and then say that there is a problem with this, and there is a problem with that,

What do you mean?

Do you want to talk about the cause of socialist modernization...... In this one aspect...... Going the wrong way?

There are a lot of magical things when I go to graduate school, for example, when a child answers political questions, he has to write the Communist Party = Party,

What do you mean by this, this, this?

Even if you write about my party in a colloquial way, it's so difficult to write Nima's characters?

No, you have to write like that, and you will have a huge iron on your head.

So sometimes it's weird,

You say I'm not bored.

No, you're so interesting, you just mean please give me a 0.

Take a step back and think carefully about where the answers to those professional questions came from.

Don't expect seniors, they are the ones who were tortured a year in advance, that's all, unless they are full scores.

Mentor? It's not possible.

They are busy with teaching, scientific research, and projects, so how can candidates sort out a solution process?

I have to take care of your level when it's over, and you can understand what you write.

As for making money......

Naive.

Mentors don't earn this money.

...... Because there are too few.

Let's put it this way, his own mentor took over the project introduced by a graduate senior.

The mathematical model is very exaggerated, there are sixty or seventy constraints alone.

Modeling + programming two steps, make it to give 600,000 yuan,

Don't you want to believe it?

Is it suddenly boiling blood and shouting in my heart: Ah! Lao Tzu also wants to make money like this!

Calm down

Those math formulas and your hair will tell you: no, you don't want to.

What's even more nonsense is that the teacher didn't ask for the money in the end, and the great god only built a mathematical model, and didn't do the programming, saying that you can get it yourself, and ask me if you don't understand anything, as for the money, it's outside.

People are not short of money, because they think it is boring, he wants to do his own research, and his ambition is to publish a nature.

It's very uncomfortable, I want to cry when I hold this model in my hand, what the fuck...... You let us figure it out ourselves, can we figure it out and I'll find you?

To sum up, the graduate school entrance examination is special here compared to the general exam - you have to collect information yourself, distinguish the information, and then understand the information.

The last step is more famous and troublesome, because those ghost questions are very floating, and there are some things that you can't understand in front of you.

Unbelief?

Let's make a basic definition, we learn to learn, just a definition, not a topic,

Rest assured, basic:

Mapping ||·||:R^n→R is called the seminorm on R^n if and only if it has the following properties:

（1）、||x||＞0，∀x∈R^n

（2）、||αx||=|α|||x||，

（3）、||x+y||≤||x||+||y||，∀x，y∈R^n

In addition, in addition to the above three properties, if the mapping is also satisfied

||x||=0↔x=0，

It is called ||·||is the norm on R^n.

In fact, it is also very simple,

It's hard to find this, so what do you think of this book?

That's because that's on page 2,,,,

The whole book is more than 600 pages.

Do you know who Wen Xiaoguang is now?

Of course, if you want to get rid of these troubles, there are four ways for you to choose, there are many choices, don't rush.

A: You've found a senior, you're a girl, you're beautiful.

B: You've found a senior sister, you're a man, you're very handsome.

C: You have something that seniors think it's beautiful and handsome: RMB.

D: Give up the graduate school entrance examination, and all the troubles disappear in an instant.

This answer can be applied in many ways.

So money doesn't solve all problems?

I'm sorry, that's for Jack Ma.

What is the pressure of studying? Are you worse than that diploma?!

Why can't you find a girlfriend? Are you missing Wu Yanzu's face?!

For Wen Xiaoguang now, the most important thing is that when selling online, buyers can't see his people.

What about a 17-year-old?

I just said that I am a doctor, and I know all those topics anyway, how about it?

Even the teacher who made the questions is from a research group, and he knows what kind of questions he likes, and he has even graded the exam papers, how?!

The only problem was that he couldn't remember the topic and wasn't a computer, so he went to the Internet café.

Anyway, Wen Xiaoxiao doesn't know, so what?

I just want to ask, again, such as, what?!

The new book asks for support, and I also ask for support.
