In a blink of an eye, it's time for everyone to go to the battlefield of the college entrance examination, and they all say that the college entrance examination is like thousands of troops crossing a single-plank bridge, and those who can pass it successfully can successfully reach the other side, but obviously Qi Yan's college entrance examination did not go so smoothly.

"In the past, the first three days of the college entrance examination will be a holiday for students to go home to recuperate, although this year is no exception, but the school still hopes that everyone can stay, and fight with their friends for three more days!

"But the teacher who wants to go back will not stop me, the examination room and the admission ticket have been issued to everyone, I wish you all the best in the exam!"

"On the afternoon of the exam, everyone gathered in the class, and no one was missing from our graduation photos. ”

Applause......

There will always be tears at the time of parting, and a person's tears are like the first drop of rain in the sky, which will always follow countless raindrops to fall on the earth.

I don't know who took the lead in crying first, the students in the class cried a lot, Lao Feng's eyes were also red, and no one could read the book in the evening self-study this night.

Probably only when you graduate from high school will everyone cry, after all, it is difficult to find such a group of people to accompany you to fight for the same dream, whether it is in the future or before!

I will never forget the girl who cried silently because she didn't understand the class, nor will I forget the student who often lectures to her classmates, knowing everything and saying everything, and I will not forget the partner who skipped class and went out to play with you, and there are many, many things that will never be done in the future and people who will never meet again.

Three days passed in the race against time among the students, and no one was absent, throwing it like the usual class, it would be better if you ignored the tension and depression of the class and the faint excitement, but at the last moment it became more and more unpeaceful.

"Students, the college entrance examination will be held tomorrow, and I would like to announce a sad news to you. ”

As soon as the head teacher Lao Feng walked into the classroom, he made the students who were about to go to the battlefield nervous. It's going to be the college entrance examination, what other bad news can there be?

Under the nervous and curious gazes of his classmates, Lao Feng slowly spoke, "The mathematics paper of our province's college entrance examination was stolen this morning!"

One sentence stirred up a thousand waves, and the first reaction of the candidates in the entire province when they heard the news was to take a look, the second reaction was what they were taking the test, and the third reaction was that the college entrance examination was going to be postponed.

When everyone was discussing this matter fiercely, Lao Feng's other sentence broke the illusions of the students.

"That's why the Education Bureau has decided to use the Olympiad Backup Papers!"

The students are not calm, what the hell is this! Olympiad ...... Spare volume ......

"Students, be quiet!" Lao Feng raised his voice to interrupt the lively discussion among the students.

"Although the science test paper has been leaked, there is a large part of our liberal arts and mathematics test papers, so in this way, it will become a set of spare Olympiad test papers for arts and sciences, I think you know what this means!" Lao Feng said with some sadness.

After Lao Feng's analysis, girls with poor psychological quality have red eyes, and the results of three years of hard work are likely to be lost because of mathematics.

Qi Yan remembered the theft of papers in 08, because a high math lecturer at her university was a candidate that year, saying that the average score in mathematics was a little more than 40, and the test of 60 was a very high score, and he took the 65 test, which became the motivation for him to choose a mathematics major, and he would brag to them every time he went to class. also said that there was a lot of crying after the exam, and many candidates fought, and some even jumped off the building, in short, the college entrance examination that year was very messy.

Qi Yan remembered that he also gave them the last big question, saying that he would get extra points for the final exam. This may not be important to other students, but it is very important to align with the inkstone, because the final grade is related to the scholarship.

So...... , so Qi Yan did the problem, but she didn't finish it, she used the method of college high mathematics to solve the problem, and only made the first two small questions. The title is vaguely impressive.

When everyone was silently anxious and sad, or when they were discussing fiercely, Qi Yan took out a piece of paper and took a pen, and silently wrote down the topic, seeing that it didn't feel right, but he couldn't think of the specific details, so he could only do so.

It was really difficult to solve it step by step, and it took half an hour.

Looking at the question in his hand, Qi Yan didn't know what to do, he couldn't give the question to everyone, and the day after tomorrow the math test would not be exposed, which made Qi Yan unable to explain.

Finally, Qi Yan folded the question and put it in his schoolbag. Stand up and walk to the podium. Looks like she's going to make a big move.

"Everyone be quiet!" Qi Yan stood on the podium and nodded slightly to Lao Feng before speaking.

"Now that everyone knows the situation, it's useless to just talk about it, and we have to take some action to deal with this unexpected situation. ”

The classmates in the class didn't know what she was going to do when they saw Qi Yan speaking on stage.

"How do you cope? It's only one night, and tomorrow the exam is over. Xu Siyuan, the squad leader, spoke first.

"Do you believe me?"

Although no one answered Qi Yan, everyone had a faint expectation for her at this time, hoping that this student who dominated the school in high school could give an unexpected solution.

"When I was in the fifth grade, I represented my country in Country M to participate in the International Mathematics Olympiad for Primary School Students. ”

Qi Yan's words caused a sensation in the class, and everyone knew that Qi Yan had a more glorious past than they imagined.

And won the first prize. Qi Yan waited until everyone's voices were quieter and continued.

None of the students in the class spoke this time and were quietly waiting for Qi Yan's next words, and at this time they seemed to see hope.

"So I still know a lot about Olympiad mathematics, although I used to specialize in Olympiad mathematics for primary school students, but I can now have such good math results because of the previous solid foundation as a support, so I want to send you a few formulas. ”

Qi Yan turned around and wrote five formulas on black and white.

"These five formulas are my own summary of the Olympiad all-round formula, it may be an exaggeration to say all-round, but they can solve 80% of the Olympiad problems. ”

"So I hope you remember these five formulas, you don't need to understand them, you just need to remember them, and if you don't know how to write these formulas together in the big math questions, especially the last big question, you must have points when you write it, believe me, there is nothing wrong!" Qi Yan threw the chalk away and walked off the stage after speaking.

The students below immediately applauded when they saw Qi Yan coming down, they are now like ants floating in the sea, and Qi Yan's formula is like a piece of driftwood that can cross them ashore.

Lao Feng has been studying these formulas written by Qi Yan, and it is really interesting to think about it.

"Okay, classmates, after my appraisal, these formulas are very practical, and they may be able to save your lives when the time comes!" said Lao Feng Xu, even if it is useless, he must say that it is useful, and the final critical moment cannot affect the mood of the student's exam.

The reason why I tell them things is that I still want them to have one and be prepared, otherwise they will collapse on the spot in the examination room.

Listening to Lao Feng say the same, everyone worked harder to copy the formula and memorize the formula, and there was a faint expectation in their hearts, and they could be a blockbuster when the time came~

Although Qi Yan said that as long as she memorized it, everyone was worried that she had to talk about the principle, and Lao Feng saw that everyone didn't have the heart to read the book, so he asked her to come up and explain the formula briefly.

Qi Yan took the stage and dismantled the formulas one by one and explained them in detail.

During the lecture, Lao Feng also brought a few top students from the first class to listen to the class, one of which was Shen Yi. The other students can leave it alone, and the matter is a foregone conclusion, but the hope of several schools cannot be given up.

"Okay, that's all, are there any questions?" Qi Yan asked as he put down the chalk and clapped his hands.

"I have long heard that Qi Yan in the liberal arts class is very good at mathematics, and when I saw it today, it was true!" The classmate next to Shen Yi touched him and sighed.

"Hmm. ”

"I want to ask, how do you know to use cracks and misalignments?"

"Oh, in fact, this last big question is generally used, the most important thing is transformation, how to transform into a method that can be used to crack the term? This Lao Feng has talked about many kinds before, some can be used directly, and some need to be found by ourselves, for example, ......" Qi Yan gave them a transformation that will be used in the last question, hoping to help everyone.

"I won't say much about the rest, if I can't do it, I'll throw these formulas on the test paper, there will definitely be a formula, and the teacher will give marks at the discretion of the teacher, and finally I hope everyone can get a good score!"

I bowed deeply in the applause of everyone.

It was nearly eleven o'clock when I returned to the dormitory, and after washing, I turned off the lights, and everyone was still reading with their own small lamps, but Qi Yan couldn't help but sleep first, I have to fight tomorrow, so take care of my spirit first.

Qi Yan's examination room is in No. 3 Middle School, which is a little far away from No. 1 Middle School. There is a group of students in the third middle school, another group is in the experimental middle school, and the remaining group is in the first junior high school, and the first middle school did not have an examination room this time. Tomorrow, the school will arrange a school bus to take the candidates who have not left the school to the examination room.

I don't know when the little lights in the dormitory went out, but Qi Yan knew that she woke people up one by one the next day, and the sleepy-eyed roommate bounced up all of a sudden and thought he had overslept.

At nine o'clock, everyone gathered at the school gate at eight o'clock to check things, and then got on the bus to take the test.

Along the way, there are a lot of traffic police to maintain traffic, there are signs everywhere prohibiting honking, and there are special passages for candidates, and the whole people participate in the college entrance examination, and the scene is very spectacular. Whether it is a test or not, seeing this scene is full of enthusiasm, and the candidates are especially dry.

The examination room has been seen in advance, and as soon as the door of the examination room is opened, everyone rushes in and walks directly to their own examination room.
