Before returning to the college entrance examination, I became popular in the science circle

Chapter 23
On Tuesday, the sensation caused by Wu Tong's counterattack to reach the top spot with perfect scores in five subjects subsided slightly.

Returning to school after dinner, squad leader Lin Yang found Wu Tong, "Teacher Chen said that you will also participate in the Mathematical Olympiad competition. There is Mathematical Olympiad training tonight, shall we come together?"

"Okay!" Wu Tong closed the advanced mathematics in his hand, took the bound draft paper and pencil case, got up and left the classroom with Lin Yang.

Every teaching building in the school has its own name, and the building where their class is located is called Bo Xue Building.Minghua Building is the building in front of them, and in front is the playground of their school.

The teaching and research section of Minghua Building is temporarily doing Olympiad training classes. When Wu Tong and Lin Yang arrived, almost all the students participating in the Olympiad had already arrived.

There are not many students in the class, only a dozen or so.

Except for a very small number of students who are really interested in Mathematical Olympiad, most of the students who come here are students who are at the forefront of single mathematics subjects to participate, and most of them are the students of the top class [-] and [-] who are in this building.

When Wu Tong came in, he was a new face to everyone.There is not much fluctuation among the top students in mathematics in the school. Many of them have participated in Mathematical Olympiad since the first year of high school, and most of them basically know each other.

When they saw Lin Yang who came in with her, all the students reacted. This should be Wu Tong who has been famous in the past two days and has perfect scores in five subjects. The new face to join can only be her.

It's only the third week of school, and the freshmen who entered the first year of high school this year haven't shown up yet.

The substitute teacher for the Mathematical Olympiad training is Mr. Duan Hongduan, whom Wu Tong has already dealt with. He has arrived early and sat down at the podium.

"Wu Tong is here!" He saw Wu Tong coming in, and couldn't help but greet Wu Tong with a smile. When he swept his eyes, he saw the book in Wu Tong's hand. He took a closer look, advanced mathematics?Duan Hong was stunned for a moment, that's right, students who have mastered mathematics in high school want to seek higher knowledge, there is nothing wrong with reading this book!

"Can you understand?"

"Fortunately, it was a bit difficult to watch at first, but the logic of thinking has been established in the past two days, and it's gradually getting better!" Wu Tong nodded. Now the teachers of various subjects basically don't care about her, except for occasional in-depth lectures, the class replied If you don't come up and ask her some questions, the basic class is no longer interfering with what she is learning.

She arranges her time freely, and has a little more time. She has already studied more than half of this advanced mathematics book, and it is expected to be fully completed within this week.

"It's a good thing to be able to see it. Take your time, there is still a big difference between high school mathematics and college advanced mathematics!" Duan Hong encouraged Wu Tong, "If there is anything you don't understand, you are welcome to consult me , or any math teacher in the school, would be happy to help you out!"

Thinking that Wu Tong had already started studying college mathematics textbooks, and the group of students in the class were still struggling with high school questions, he couldn't help but want to give this group of people some stimulation.

He pointed out his identity and introduced to the people in the class who had arrived: "This is Wu Tong. You should be familiar with Wu Tong. He is the only one who got a perfect score in the mathematics test this time. He also took this year's college entrance examination paper on the day when the results came out. I What I can tell you is that it’s still a perfect score!”

"There is heaven outside the world, and there are people outside the world. You should learn from Wu Tong. Don't think that just because you are better at math, you are number one in the world!"

"Understood, old Duan, you are not guilty of comparing us with such a super learning god!" Those who can enter this class will have the same grades, and the relationship with the teacher will naturally be more harmonious and close. Cheerful couldn't help but screamed mischievously!

"That's right!" Others cheered. Can a genius like them, who can get full marks on the college entrance examination papers, study the entire high school knowledge, and is already studying college textbooks, be comparable to them?Lao Duan really thinks highly of them!
"I think you guys are too idle and you are very good at talking. Let's take a mock paper and do it today!" Duan Hong was almost annoyed by this group of unsatisfied people. "Wu Tong, find a seat first." Sit down and do some mock papers on the Mathematical Olympiad test today. There are some differences between competitions and ordinary exams."

There were still many empty seats in the teaching and research room. Lin Yang had his own seat, so Wu Tong randomly picked an empty seat in the middle and sat down.

Duan Hong started to curl his hair, and the boy in the front row turned around and passed the papers over. He wore glasses that could not block the sparkle in his eyes, and he still had some baby fat and round face. He greeted her with a playful smile: "Boss, I am Sun Chao from Class [-], please take good care of me!"

Wu Tong recognized that he was the one who spoke out first, saying that Mr. Duan was right or wrong.

"Wu Tong, Class [-], God of Science, please take care of me!" If she remembered correctly, this was the one who was known as the little prince of science!

Mathematics seems to always get full marks. This time the one with 148 in Mathematics is him, right?His science scores are either perfect or close, even if his Chinese and English are a bit behind, he only hovers around [-], and he is also among the top grades.

As the test papers were handed out, all the students began to calm down and focus on the papers in their hands.Everyone is a top student in the top grade, so there is still some level of psychological control.

Wu Tong looked at the paper in his hand. There were not many questions on the paper, only four major questions.But it covers almost everything, including plane geometry, algebra, number theory, and combinatorics. Compared with the basic papers she studied before, the difficulty is not at the same level.

The first problem is plane geometry. In the acute triangle ABC, the height CE on AB and the height BD on AC intersect at point H, and the circle with DE as the diameter intersects AB and AC at points F and G respectively. FG and AH intersect at point K, given that BC=25, BD=20, BE=7, find the length of AK.

Wu Tong got some real questions in this area during the summer vacation, but not many. She successfully completed the high school courses by herself, and after she had the idea of ​​participating in the Mathematical Olympiad, she began to pay attention to the practice questions in this area. Time is limited, and she hasn't touched much yet.

As for the Mathematical Olympiad, it can only be said that we are on the threshold.

However, for the high school Mathematical Olympiad, the final assessment is high school knowledge. Even though Wu Tong has not formed any Olympiad thinking and is not familiar with the angle of the Mathematical Olympiad questions, but for her who has thoroughly mastered the high school curriculum and studied ahead of time, it finally comes down to one sentence Speaking or solving problems, she is really not afraid of this.

After carefully reading the questions, Wu Tong already had some ideas in his mind, so he wrote a few strokes on the draft paper to sort out his ideas.Wu Tong began to write on the paper:
Known BC=25···
AC·BD=CE·AB····
····AK=9*24/25=216/25。

The first question was successfully solved. It was a warm-up question and was not difficult for Wu Tong. She spent more time writing about the problem-solving process than thinking about it.

Wu Tong then moved on to the second question. There were two questions in the second question, each one more difficult than the last.

When Wu Tong read the questions for the first time, he was still a little fuzzy, which is a rare state in recent times.After reading the questions again and again, and thinking carefully, Wu Tong really got the start. The knowledge points that were running rapidly in his mind were connected in series and turned into problem-solving ideas, which were mapped to Wu Tong's heart one by one.

The second question, once again conquered, the complicated process of solving the problem, rustled in Wu Tong's pen.

Most of the students in the class were still troubled by the first question and were still looking for ideas. Wu Tong's coherent writing sound was particularly obvious in the quiet classroom.It caused other people to look at Wu Tong in awe and envy. Is this the second question?They haven't figured out the complete idea of ​​the first question yet, how terrifying are the strong academic gods?The crowd quickly turned their heads to think.

Don't waste any more time, don't worry, the boss is about to hand in the paper before they finish the first question!They have already heard of Wu Tong's style of handing in the paper half the time early.
