Old bird Wen Xiaoguang is quite familiar with the postgraduate entrance examination forum, so it is not a problem for him to find a few past papers.

This thing is difficult to say, because the scumbags not only want to sort out the past past questions, but also have a special neat and standardized answer detail, and it is better to have study notes from people who have come before, and it would be better if they could provide some practice questions.

Best of all, of course, all of this is free.

I don't know how much money it cost when I was admitted to college, and when it came to collecting such important information for the graduate school entrance examination, those children asked in the first sentence: dear, is it free shipping?

Thinking of these stalks of the year, Wen Xiaoguang was happy,

Get things done while having fun. Although the USB flash drive was borrowed from Wen Xiaoxiao, and the money was borrowed from the nonsense, it seems that he has already made money.

It's a little floating when you walk.

As for how to explain the money, he is not worried, it is more difficult to make up a reason to fool the stupid people in the family than to make money.

Just after 12.40, he came out of the Internet café, went to the print shop outside, printed ten copies of the test papers, bought a dozen more A4 papers, and then returned to the classroom.

In the morning class, mathematics, English and physics were all very relaxed on the first day, and I probably talked about some things, focusing on sorting out the structure, mentioning some simple conceptual things, and salvaging the students' memories.

For example, Lu Yonghua systematically talked about some sets and basic elementary functions in high school mathematics, and especially emphasized the problem of constant formation in high school mathematics.

Most of the students still haven't recovered during the holidays, and some little girls have fallen into Wen Xiaoguang's place, and the classroom atmosphere is very ordinary.

Despite the beautiful weather today, there was reluctance on everyone's face.

Only Wen Xiaoguang is very comfortable,

He sat in the corner of the back row, leaning against the window, opening it a little bit and blowing the wind, this kind of class rhythm he was very familiar with, and he didn't hate it.

After all...... As a student from childhood to adulthood, the feeling of beating others,

It may not be good to say so,

But really...... It's pretty comfortable.

At noon, he didn't have the habit of taking a lunch break, and he could write down the questions on those test papers, just ten test papers, although some of the questions were more tricky, but it was not difficult for him, of course, some time was still needed.

And we must hurry up, because the end of December is the time for the graduate school entrance examination every year, and the professional courses are already to be reviewed at this time, in other words, many senior students who want to be admitted to Jiangnan University of Technology are waiting to be fed at this time.

The money is waiting for him to pick it up.

Wen Xiaoguang has to get things done in a few days.

Getting money is the first step to escaping from the witch's clutches.

Dai Weiyi had already taken a break in the afternoon, and he took out something: the 2002 Jiangnan University of Science and Technology master's degree entrance examination questions.

On the left side of the desk, there is a roll, on the right is an A4 paper, and a pen is ready.

The first question is relatively simple, short-answer questions, listing the traffic distribution model, explaining the principles and applicable conditions, which can be memorized.

This part is the focus of this major, and it will definitely be examined, which can be roughly understood as a method implemented in four stages, each stage has its own various models.

This question is one of the stages of the investigation.

Answer: Start with the gravity model.

Wen Xiaoguang's mind has long been engraved with these things, his words are very good-looking, in order to be easy to read, the writing is not scribbled, horizontal and vertical block letters, like a print: the gravity model is the most widely used travel distribution model in urban transportation, the main principle is that the model assumes that the travel generation in the two intervals is proportional to the travel generation in the departure area, and inversely proportional to a certain power of the traffic impedance in the two intervals. The formula is expressed as: Xij=k· Ti· Uj/tij。

The meaning of the letters in question is to be explained.

Next, we can talk about the scope of application.

The above will probably tell the reviser that you know this thing.

But it's all memorized content, it's like poetry, you can memorize it, there's nothing bullish, let you explain the meaning, you're stupid.

If you want a full score for this question, you can also tell the reviser that I will use this model.

For example, how the relevant parameters in the model are valued in solving practical problems, Wen Xiaoguang naturally wrote it down: the k parameter in the formula can be taken from the existing model of similar cities, and the travel distribution curve is calculated accordingly, and compared with the current travel time distribution curve obtained from the starting and ending point survey, and then the correction coefficient is obtained, and iterated one by one.

This is one of the methods, and it can also be said that this kind of calibration has a lot of work, but the factors considered are more comprehensive than the increase coefficient method, which is too simple and crude......

The problem is that the formula of the model must not be written wrong, and not a single exponent can be written wrong.

It makes sense whether the letters are multiplied or divided, added or subtracted, and if you write them wrong, it means that you don't understand the logical relationship at all.

You say I made a clerical error, it's okay, no problem, just call him and explain when you go back and wait for the grader to change the test paper.

This is actually the easiest question, because half of the answer can be memorized.

The next is not so good, to give you the problem calculation, from the simple Dijkstra algorithm, to the Beckmann traffic balance model that requires a little bit of strength, from UE to so, and then to the difference between the two,

There are even a few years when there are basic questions about optimization theory, which are very demanding for undergraduate students.

In a word......

This is a good-looking girl blind date, this is a professional class pressure score, weigh it yourself and then take the test,

During the lunch break, there were not many people in the whole classroom with their heads up, and rows of children buried their heads in the stacks of books, even if they had to lie down for a while in order not to study.

Wen Xiaoguang is relatively rare and can make writing sounds, and there is also a little girl in the front row who has been doing her homework.

He was more attentive, so he didn't pay much attention to it.

But they turned their heads to look at him a few times.

When it was close to 1:50, the school bell rang, and Dai Weiyi raised his head in a daze, with red marks on his forehead, and he slept soundly at first glance.

Wen Xiaoguang accosted him, "Awake?"

Lao Dai's face was wrinkled, "Ah, you didn't sleep?"

"I'm not sleepy. ”

"It's really energetic," Dai Weiyi glanced at what he was writing and asked, "What kind of homework is this?

Wen Xiaoguang: ......

Not wanting to dwell too much on this, he only said, "You're drooling." ”

The corners of the mouth and the paper are connected by a crystal thread, and the saliva on the book outlines a heart shape.

What the hell did this kid dream about?

Dai Weiyi smiled hesitantly, and quickly wiped the paper.

At this time, Wen Xiaoguang also drew the last full stop of the answer to a certain question, and packed up the things and put them in the belly of the desk.

According to the class schedule, I will have a physics class for a while.

Middle school physics is very simple, but I have forgotten a lot of it for a long time, and I rarely practice the topics, so I need to listen to it roughly, just roughly.

In the past, when he was in the third year of junior high school, he was called Science 305, which means 15 in mathematics, 100 in physics, and 100 in chemistry, with a total score of 350.

The only thing that may be troublesome is English, after all, speaking well does not mean that the test is good.

After putting the book away, just about to go to the toilet, the girl sitting in front of them turned her head and took the math information book, "Wen Xiaoguang, there is a question I don't understand, can you help me read the next step?"

Slightly stunned,

Girl, why do I vaguely remember that you were napping in math class in the morning?

Could it be that I misunderstood, but you actually love to learn, right?
