The newspaper Su Chen read, there was a news that "the National High School Mathematics League is about to be held", Su Chen was a little surprised, this competition is usually held on the second Sunday of September every year. I don't know why it was suddenly postponed this year, this is what surprised Su Chen when he saw this news.

Su Chen had participated in this competition before, and the results of the competition were self-evident, and the promotion of the first prize was certain.

The full name of the National High School Mathematics League is the National High School Mathematics Joint Competition, which is a higher-level mathematics competition in the subject of high school mathematics in China, and its status is much higher than that of the mathematics competitions organized by the provinces.

About 400 students across the country who have achieved excellent results in this competition are eligible to participate in the CMO hosted by the Chinese Mathematical Society.

CMO is the Chinese Mathematical Olympiad, and CMO is the highest-level, largest and most influential mathematics competition for middle school students in China.

Those who enter the CMO and beat other contestants to win the final award are basically booked an admission letter from a first-class university in China, which is the legendary escort.

If you have a higher pursuit, then the top 30 members of the CMO can participate in the training camp, and this training team is the national training team, representing the country to participate in the IMO.

IMO is the International Olympiad, and that is another level of competition, IMO is about the existence of national honor.

So don't underestimate this national high school math league, it's a stepping stone to a CMO. Of course, it's not even a fart in front of IMO.

However, this is enough to leave domestic middle school students in the dust.

Su Chen's first reaction when he saw this news was: "Then my students still have a chance this year!" ”

Su Chen thought that this competition was over, but he didn't expect that it would not be held this year, so could he let the students participate in it? Su Chen thought of Yu Linjing.

Su Chen, the other students, didn't dare to say it, but Yu Linjing, the only student in class eight, Su Chen felt that he could still tutor her.

I just don't know if Yu Linjing is willing to participate, after all, this is not only to solicit the opinions of the school, but also to solicit the wishes of Yu Linjing herself.

Su Chen kept this matter in mind, and planned to ask Yu Linjing again when he gave the eighth class a math class in the afternoon.

Su Chen continued to read the newspaper again, but he didn't expect Su Chen to see a news about mathematics again, which made Su Chen very excited, it was really a lot of games.

Su Chen's startled move aroused the curiosity of Lin Wenxin, who was sitting at the front service desk.

"What is this Su Chen looking at? So excited? I'd love to see it too. Lin Wenxin thought to himself.

But out of the principle that girls should be reserved, Lin Wenxin still suppressed the restlessness in his heart.

Although Lin Wenxin was very stubborn in his heart, his body was always looking in the direction of Su Chen very honestly, and it became more and more frequent.

Su Chen didn't see Lin Wenxin, who was about to become a "Wangfu Stone", and Su Chen's attention at this time was all on the newspapers.

This is a news about the "National" Casio Cup "High School Math Graphing Calculator Competition", Casio Graphing Calculator I believe many people are familiar with it, this is a brand of calculator commonly used by students, of course, the calculator here is just one more function than ordinary calculators, that is, it can display the graph of functions.

You don't need to artificially draw a diagram or calculate the intersection point, solution set, etc., it can give you the answer in one step and very clearly.

Even the loan does not require you to list the formula, just enter the known value, and you can find the value you need.

It is a very advanced calculator, of course, this is relative to ordinary calculators, some people say that you can't use a calculator for the exam. (Except for the Magic Capital.) Wouldn't it be bad to use a calculator on a regular basis?

In fact, this is not the case, if your basic skills are solid, when you usually scan the problem, you list formulas, functions, sequences, and even equations, etc., and then use the calculator to calculate the results, which saves a lot of scratch paper is secondary, and the most important thing is to save yourself a lot of time to solve functions and draw pictures.

Calculating and solving equations are all basic skills, and you won't be able to solve them because you have a calculator to help you, of course, you still need to solve them yourself during the exam.

The calculator can only be used to save time on calculations when solving problems, so that you can save a lot of time to review other subjects.

Su Chen felt that this competition came very timely, and Su Chen felt that most of the students in his class could participate in this competition, because the threshold of this competition was very low, and they did not need to have extraordinary mathematical talent like the previous National High School Mathematics League.

And although the questions are difficult, most of the questions can be solved by calculators, and candidates only need to figure out the solution ideas, sort out the key points, and finally list the equations or equations, functions, etc., to find out the answers.

However, these questions are generally very large or very small, and they need to be accurate to a few decimal places, or a few times in ten.

Generally, manual calculations require a lot of time and brain power, but calculators are different and very convenient.

Su Chen planned to find a few students in the class who had good math scores to participate in this competition.

Because after winning the award in this competition, you can get extra points for the college entrance examination if you win the national award. (In reality, the college entrance examination has been completely canceled as a bonus item, but my book is not reality, so don't substitute for me, just because I'm bragging!) ）

This is very advantageous for students, and with a little score above others, it may rise by hundreds or even tens of thousands of rankings in the province.

Su Chen glanced at the contact information for the registration under the newspaper, Su Chen smiled, the registration contact person was Cui Tong, who was Su Chen's former classmate.

Su Chen has his contact information, so he will not record it, and Su Chen has to communicate with the school to determine whether he can let students participate in this competition.

After all, this is not Su Chen's words, if he takes the students out to fool around, if the school leaders and the parents of the students blame him, it will be difficult for him to say clearly, although he has good intentions, but others may not be willing to accept your affection.

Su Chen took the newspaper and walked in the direction of "Brother Yun" refreshedly, and Lin Wenxin, who had been paying attention to Su Chen's dynamics, immediately pretended to be casual and continued to write her things.

"Hee-hee, Brother Yun, I want to ask you something!" Su Chen leaned on the service desk in front of Lin Wenxin and asked with a smile.

"Say, I'm busy!" Lin Wenxin pretended to be reserved, but in fact, she couldn't wait for Su Chen to talk about it and tell her everything he had just seen in the newspapers.

"I want to take students to participate in the competition, what is the process, and who do I want to tell me? What needs to be done? Su Chen said his question directly, Su Chen didn't know if this school usually let students participate in some competitions, so it was better to find an acquaintance to ask.

"What are you going to compete in? In the general competition area, the big competition schools in the city will have a notice. Lin Wenxin said, in Lin Wenxin's eyes, the so-called competitions are nothing more than some competitions organized by the district and the city, the scale is average, and if you win the award, you will get a certificate or something, at most, the city will win the award, and go to participate in the provincial promotion competition.

Because there are too many leaders in the province, there have been no students in the school who can win awards in the province for many years, and the school is paying less and less attention to this aspect, so Lin Wenxin feels that participating in this kind of competition is simply a waste of students' precious time. The city's award college entrance examination does not add points, and it feels a bit worthless to sacrifice precious revision time to participate in such a meaningless competition.

"These two!" Su Chen directly put the newspaper in front of Lin Wenxin and pointed to the titles of the two competitions.

"The National High School Mathematics League, isn't this going to participate in the city and province pre-selection competitions, and only students who have passed the screening can participate, right? The provincial competition is already over! Lin Wenxin said that although Lin Wenxin had not participated in this kind of national mathematics competition, he also knew the general process.

Generally, the national competitions are screened layer by layer, level by level, and to participate in the national competition, they generally have to win awards in the province or in the region or special zone. Although this year's national competition has been postponed, the provincial and municipal competitions should have already ended, and the students from their own schools have not participated in the city and provincial competitions, how to participate in the national competitions?
