Chapter 10 So terrifying

Soon, Lin Xiao was taken to the conference room next door.

Obviously there was no meeting to be held today, so Ding Ping arranged for him to come over.

As a national special teacher, Ding Ping is relatively well-established in the school, and having some power is not a problem.

"You start doing it now. You get out of school at five past ten, right? Then you do it until ten o'clock, and then I'll see how you do. Don't be in a hurry when you do it, just do it at your own speed. , this paper is stipulated to take 230 minutes to write, which is the time it takes to complete the first and second trials of the league."

"Okay." Lin Xiao nodded, looked down at the paper, and couldn't help but wonder, is this a small opportunity for himself?

Without further ado, he took the pen and scratch paper that Ding Ping gave him and began to read.

Ding Ping stood behind and did not leave for the time being, watching how Lin Xiao planned to solve the previous questions.

If it were Lin Xiao before, if someone stood behind him and kept watching him write the question, he would definitely not be able to write the question. But now, with the help of the system and the fact that the question is indeed difficult, he quickly entered again In this state, he forgot that there was another person standing behind him.

This paper has a total of fifteen questions, with a total score of 300 points. The specifications are indeed comparable to those of the league.

One of the test questions consists of 8 fill-in-the-blank questions and 3 answer questions.

Lin Xiao got it and started writing the first fill-in-the-blank question directly without browsing the following questions.

The first question was a sequence question. Lin Xiao figured out the answer as soon as he saw it.

In the high school mathematics league, the first test questions are relatively not as difficult as the second test. In addition to testing the flexible application of various knowledge, the first test questions also mainly test whether students can remember these high school knowledge.

For example, the first question that Lin Xiao did was in the geometric sequence An, A9=13, A13=1. What is the logarithm of 13 with A1 as the base.

This tests students' observation ability and their grasp of the relationship between the numbers in the geometric sequence.

Lin Xiao took a quick look and found the key element, namely A1:A9=(A9:A13), so the answer came out, which was 1/3.

Next, there is the second question, a vector question, which combines the knowledge of ellipses.

For most students, this kind of question is a bit difficult, as it is both an ellipse and a vector. However, it was still not a problem for Lin Xiao and he passed it quickly.

Ding Ping, who was behind him, was finally truly surprised when he saw Lin Xiao's problem-solving speed. Only three minutes had passed, and this boy had actually written out the first two questions?

In Ding Ping's eyes, Lin Xiao had an idea after thinking about the first question for less than five seconds, and he also had an idea after thinking about the second question for less than ten seconds.

He realized that he had really found a treasure now.

The difficulty of the questions may not be too difficult, and if it had been someone else, they would have been able to do it.

But this speed of finding ideas is truly a gift.

He even began to think in his mind, should he find the math teacher in Lin Xiao's class, drive him away, and then personally teach their mathematics? What a beautiful thing it would be to be able to teach such students?

But he just thought about it, this kind of thing is a bit peach picking.

At this time, Ding Ping came back to his senses, and when he looked at Lin Xiao again, he found that he had already completed the fourth question. Looking at the time again, less than six minutes had passed.

He sighed deeply in his heart.

Then turned and left.

Maybe he would get a surprise when he came back in two hours.

Of course, there is another kind of accident. What if Lin Xiao encounters an accident in the following questions?

However, Ding Ping still believed in Lin Xiao's talent.

…

Ding Ping's departure did not affect Lin Xiao. He was still immersed in the topic of the paper.

The first questions are an appetizer, and the difficulty becomes higher as you go to the back. However, the higher the difficulty, the higher the pleasure he will get when solving the problem.

In this way, in a clock in the conference room, time passed quietly with the rotation of three hands, and ten o'clock came on time.

The door of the conference room opened and Ding Ping walked in.

"Lin Xiao, okay, it's ten o'clock, you..."

His voice stopped suddenly because he suddenly saw that Lin Xiao had actually written the third question of the second test, and it seemed that he had already completed nearly half of it!

He couldn't help but be shocked.

This Lin Xiao's speed is really too fast!

Two hours, a total of 120 minutes, and the first test takes 80 minutes, which is 40 minutes more. But what you need to know is that the second test lasts 150 minutes and has only four questions. On average, one question takes 37.5 minutes.

And now, in one hundred and twenty minutes, Lin Xiao not only completed the first test questions that originally took eighty minutes to complete, but also completed the second test questions that were originally calculated to take nearly one hundred minutes?

This reminded him of the math exam he took in proctoring. It took Lin Xiao only one hour to finish the two-hour question.

His understanding of this boy's talent became more and more profound.

If I had started training when I was a freshman in high school, wouldn’t I have the chance to win the provincial first grade by now, or even join the provincial team to participate in the CMO?

He felt a little regretful because their school's educational resources were limited and they had no time to set up a special competition class.

Seeing that Lin Xiao didn't seem to hear his words, he had no choice but to say again: "Lin Xiao, okay, just do this. It's already ten o'clock."

This time Lin Xiao finally recovered from the test paper, turned to look at Ding Ping, and asked doubtfully: "Teacher Ding, what's wrong?"

Ding Ping didn't know whether to laugh or cry: "It's already 10 o'clock, you must be too involved."

Lin Xiao was stunned for a moment, a little surprised: "It actually went by so fast."

He stood up from his seat and stretched his body, while Ding Ping took his paper and looked at the questions he had already written.

As expected, all the first test questions were written, and the first two questions of the second test were also completely written.

However, because the paper was one that Ding Ping found at random and he had never done it before, he didn't know what the answer was yet, so he had to check the answer for Lin Xiao.

So he took Lin Xiao back to the office, found the answers to this set of papers, and got them right.

"Well, the fill-in-the-blank questions in the first test...all are correct, and the answers to the three answer questions are all correct."

Doesn't this mean that if this was a formal exam, Lin Xiao had already obtained full marks in the first test?

Ding Ping was quite surprised.

However, what Ding Ping is looking at now is only the final result, not the process. After all, there is no time for the moment, and the process score is also more important.

But Ding Ping made an estimate and found that Lin Xiao's process should be fine.

Then comes the key point, the second test question.

The answers to the first and second questions are correct. The third question is a geometric proof question. The proof question completely depends on the process. Ding Ping took a brief look at Lin Xiao’s thinking and knew that his thinking was basically correct. Yes, but it only proves half of it, and there is still half left to write, but there is a high probability that it will not stump Lin Xiao.

This is equivalent to saying that Lin Xiao has a high probability of getting 250 points out of 300 points.

What is this concept?

This is equivalent to Lin Xiao basically undoubtedly being able to become the top 100 or even the top 50 in the country, and then participate in the CMO winter camp, enter the National Mathematical Olympiad, and even have the opportunity to participate in the IMO, International Mathematical Olympiad. Mathematical Olympiad!

This boy is so terrifying!
