Goldfish teacher emphasized that mathematics should be done as soon as possible, so that students have the illusion that if mathematics does not start from the fertilized egg, no, it starts from the separation of homologous chromosomes in the late stage of the first division of meiosis, then they will achieve nothing on the road to mathematics.

If according to this "early" standard, how many students who participate in the tutorial class will be brushed off, Lu Xi doesn't know, she feels that she will definitely be brushed off.

In her previous life, she was not engaged in mathematics, although she was not a scumbag, but what she learned did not match mathematics at all. Lu Xi, the predecessor of this life, is a veritable liberal arts tyrant, a scumbag in science, and he has never studied mathematics well.

However, according to the dream of that God mathematician, with his very useful brain now, Lu Xi felt that she could still set mathematics as her goal, so she agreed with Mr. Jin's words to hurry up.

Because of the few mathematicians who were involved in mathematics competitions cited by Mr. Jin, they are now famous young mathematicians, such as Grigory. True geniuses such as Perelman and Tao Zhexuan have all been exposed to mathematics from a very young age, and have studied mathematics in depth.

These great gods, at her age, have already laid a certain foundation.

As for her, according to incomplete statistics, the real time invested is about 5 months. Compared with the real power of mathematics, it is too far and too far away.

And the basic knowledge base of mathematics, which has been developed for thousands of years and accumulated for thousands of years, is so huge. In the field of mathematics, it is not easy to review the past alone, and it is even more difficult to learn the new.

Thinking about it like this, Lu Xi realized that he had been too smooth in life and study recently, and unconsciously he was a little floating and his tail was a little upturned.

"No wonder Lao Kong said that if I want to examine my body three times a day, I will not find my own changes if I don't calm down for a long time to examine myself, criticize myself, and dissect myself. The change of boiling frogs in warm water is really not easy to perceive. ”

This discovery made Lu Xi feel ashamed, after all, he was a person who had lived two lives. Although each life does not live too long, it should not be.

I have to say that the sugar-coated cannonball is so powerful that if people are not careful, they may get lost in the praise.

Pressing down the floating heart, Lu Xi calmed down and began to listen carefully to the class.

Of course, the tutorial class in the senior year is very different from the first year of high school, the first year of high school is still in the basic knowledge, and the students in the senior year have mastered the basic knowledge of the number competition, such as some commonly used formulas and common theorems in the second test of the number competition, the difference is only whether it can be used flexibly.

What the instructor wants to talk about is this flexible problem, some mathematical ideas, and some technical things.

Give a typical IMO question, what kind of knowledge is involved in this question, where to start to solve this problem, and what ideas are available.

Mathematics is not Huashan, and there will not be only one path to take. Some people do this problem and solve it after writing a small half page, while others write several pages with different ideas, although in the end they have the same goal, but the process is different.

Of course, it is not enough for the teacher to always explain that it is not possible to blindly indoctrinate it.

Sometimes you seem to understand what the teacher says, but when it comes to doing the questions, you will be blind, this phenomenon is too normal.

What to do, rote memorization will not work, the Olympiad is a bottomless pit, all kinds of questions are ever-changing, you memorize one, come out of another slightly changed, and it will not be. At this time, you can only do the questions independently, thoroughly understand the knowledge you have learned, cultivate the thinking mode of mathematical competition, and master the thinking methods.

The problem is very simple, the teacher sends down the same simulation paper as the league, and focuses on solving the paper in the morning and explaining the paper in the afternoon.

Although the students in the first and second grades of high school and the third year of high school have different learning progress, each of them has their own pride and wants to prove themselves.

In the first two days, the mock paper was relatively simple, even a few students in the first year of high school could score more than 90 points in one test, and the brothers and sisters in the second and third years of high school scored more than 100 points. As for the second test, it is much worse, most of the senior high school students can do two or three questions, the second year of high school can do one or two, and the high school one, except for Lu Xi, some can do one, and some can't do one.

In the following days, the difficulty of the simulated paper gradually increased.

At this time, even if it is a test paper, the score of the first year of high school cannot go up, and it is often a test of thirty, forty, forty or fifty, and the senior brothers and sisters of the senior who passively take the test of 100 are crushed so that there is not even a slag left. The sophomore in high school is a little better, and there are still seventy or eighty points.

The first attempt is already unrecognizable, let alone the second attempt. In the second year of high school, there is one that can't be done, but in the third year of high school, it is generally possible to do one or two. In the first year of high school, except for Lu Xi, who is still insisting, he has been completely blinded.

The kind of wretched bag that stared at the roll but couldn't use the strength was so aggrieved that Xi Haoran and Hu Wenliang were pale all day long.

But young people have a breath of energy, which may not be ambitious, but this breath can enable them to withstand failures, withstand setbacks, get up from where they fall, and make up for their shortcomings.

It's just that the Olympiad is a thing, and it's not easy to quietly find a tutor outside for tutoring. What can be found, the level is too poor, and it can't make up for it at all.

Looking for instructors, there are only a few instructors, and there are only two really high-level ones, and there are more monks and fewer porridges.

Looking for a senior brother or sister in the second and third years of high school?

It is said that twenty or thirty of the leagues this year are likely to win the first prize, and several may enter the provincial team. But it's okay to ask them to learn some experience, and it's impossible to learn from each other for a long time.

There was no way, they finally found the teacher, Teacher Fu Yefu in this class.

"You guys, you're just not modest, don't you see a 'teacher' far away in front of you?" Facing the disciples' requests for help, the old man said.

Xi Haoran and Hu Wenliang suddenly realized that they remembered Lu Xi who was in the tutoring class with them. In the mock exams of the tutoring class, the girl was the only one who stood out in their first year of high school. And even compared with the senior brothers and sisters in the second and third years of high school, it is not inferior, and even more than 99% of them.

It was very surprising to the senior brothers and sisters in the tutoring class, and even the goldfish teacher was full of praise, and he was like a god.

Lu Xi's side, seeing Xi Haoran and them, asked to study together, as far as she was concerned, if there were like-minded people who wanted to make progress together, they would naturally not refuse.

What's more, the boys in these classes, according to her observations, are not not smart enough, but they started too slowly to keep up, after all, they are the last to learn, and they have been studying for a year.

Soon, a digital competition discussion group centered on Lu Xi was established.

Because the math competition has long been canceled (CMO and league associates), the competition is no longer as safe as before, and it is possible to invest too much time in the math competition but fail to produce results, but delay the college entrance examination and fail at both ends.

Therefore, this group was nicknamed the Olympiad death squad by Xi Haoran, and it meant that for the sake of mathematics, he would not rush into it.

The group meets almost every day to discuss the aspects of mathematical competition.

The time is generally after dinner in the evening, and the location is generally in the canteen and Juqingyuan, and the discussion is sometimes a topic, sometimes a certain knowledge point, sometimes a mathematical idea, sometimes a thinking method, and so on.

In the team discussion, no matter what kind of topic Lu Xi can almost find, the prototype of the question can be found, and some can even be solved in several ways at the same time. No matter what formula or theorem it is, Lu Xi can deduce it and say why.

This made Xi Haoran and Hu Wenliang admire them at the same time, and at the same time, they worked harder, and Lu Xi did not let the women have their eyebrows, they did not strive for self-improvement, and they were not worthy of being bearded eyebrows.

With Lu Xi's help, they have worked very hard, and with a two-pronged approach, their progress is very significant. Lu Xi himself, with like-minded people, had a fierce collision of ideas, and felt extremely down-to-earth, and the illusory sense of floating before was swept away.

As for this Olympiad death squad, it later became famous, and other students who were engaged in math competitions in the first year of high school knew about it and asked to join one after another, which is already a later story.

On the other hand, there is a sense of competition between various grades, and they are secretly competing, so that you are chasing me, and the atmosphere of the tutorial class, which was originally relatively loose, is tense and cohesive, and it gets better.

The instructors looked at it and nodded secretly. The competition is all about the courage and perseverance. Although preaching has a certain effect, where can it compare with the motivation of students from the heart. R1152
