CHAPTER XXVII

Twenty minutes later, the second test began.

Unlike the first attempt, there are only four questions on the second attempt.

Four questions, including plane geometry, algebra, elementary number theory, and combinatorics.

Each question is worth 50 points, and the full score is 200 points.

Exam time, 150 minutes!

Although the number of questions in the four questions seems to be very small, according to the average data of previous years, the more than 10,000 candidates in each session can complete a question within the specified time of 150 minutes, less than one-third of the total number of contestants.

Because the difficulty level of the second test question is too high.

After all, the questions of the second test are in line with international standards.

In other words, to prepare for the IMO (International Mathematical Olympiad) to select talents.

If the difficulty value of the second test question is compared to 100, then the most difficult question in the first test just now may not even be 50 difficulty value.

In the second test and four questions, as long as you can answer one correctly, you can be said to be the best among ordinary people, a genius-like existence.

If you answer two questions correctly, you can be regarded as a genius among geniuses.

If you answer three questions correctly, you have broken through the boundaries of genius and stepped into the ranks of demons.

Four correct answers!

Sorry, so far, there has been no such monster in Qidong Province for four years in a row.

............

"The second exam has officially begun, please start answering!"

The sound of the opening of the exam came out on the radio, and every candidate in the examination room acted quickly.

For different candidates, the strategies for coping with the second test are different.

For example, if some candidates are good at plane geometry problems, then they will spend 150 minutes to gnaw on that plane geometry problem, and if they can do that problem, they will be considered to have completed the goal.

And some candidates choose to be wet with rain and dew.

It's to do every question, although it must not be done, but at least you can earn some step points.

Bizzie also has a strategy, and his strategy is simple and brutal.

That is, starting from the first question, make all four questions in order!

Before the exam, Bi Qi came with the idea of completing all four questions.

He knew that Mr. Gu had a good record in the National High School Mathematics League that year - the only perfect score winner in the province that year!

As a student of Teacher Gu's personal tradition, Bi Qi feels that even if his grades are worse than Teacher Gu's, he can't be too bad!

Otherwise, it would be too embarrassing.

"Come on, don't embarrass Teacher Gu!"

After cheering himself up, Bi Qi looked at the first question.

It was a question that examined the knowledge of plane geometry.

Bizzie only scanned the question once, and knew that it was a rather tricky question.

But Bizzie didn't panic at all.

In the detailed explanation of the set of typical example questions that Gu Lu gave him before, there were several questions similar to this one.

And Bi Qi has long been familiar with its solution.

"Here, you need to put a P here, and then connect the SB to draw the perpendicular CF. Bizzy pestled his chin with the barrel of his pen, the pencil sketched on the test paper, and his brain was racing.

"Next, should you use Menielaus's theorem or Ptolemy's theorem?" Bizzy frowned and thought for a while, and wrote a few strokes on scratch paper, "Neither of these theorems apply, you should use Simson's theorem!"

Bi Qi muttered something under his mouth as he continued to reason about the answer on scratch paper.

Plane geometry is one of the types of problems that Bizzie is best at.

So except for a little bit of stuckness in the middle, the rest of the process was smooth sailing.

"It's finally done!"

In the twenty-fifth minute of the exam, Bi Qi successfully calculated the answer to the first question.

But Bizzy at the moment is not so easy.

More than 20 minutes of ultra-high-intensity calculations is a big drain on his brain power.

Bi Qi looked at the second question of the second test.

That's a combinatorial math problem.

Before reading the title, Bizzie was still a little worried.

After all, he had done an IMO combinatorial math problem before, which was the homework problem that Gao Yunjin left for them to calculate the minimum separation side.

At that time, the question left a deep impression on Bizzie, or rather, a shadow.

He had been struggling to solve it all day, and he didn't have the slightest idea.

It wasn't until he was ordered by Teacher Gu that he completely comprehended it.

So Bizzie is very worried that the combined math problems in this high school math league will be as perverted as that problem.

But as it turned out, he was completely overthinking.

The Chinese Mathematical Society will not have an IMO level difficulty problem in such a mathematics league at all.

Otherwise, the full score for the second test will no longer be 200 points, but 150 points.

After Bi Qi glanced at the question, he could barely hide the joy in his eyes.

In his opinion, this combinatorial mathematics problem is not as difficult as the plane geometry question just now.

The trouble is nothing more than complex calculations.

Rustle~~

The tip of the pen touches the paper, and the rhythmic sound of writing resounded in the examination room.

In this environment, everyone is like a taut string.

Ready to go, but at any time there is a danger of breaking.

............

Outside the exam room.

The sun hung high, scorching the land mercilessly.

It's a terrible hot day.

Even though he was sitting in the pergola, Gu Lu could still feel the heat wave coming from the shop.

Principal Chen and Principal Jiang seemed to have swept away their depression and began to talk and laugh.

Gu Lu raised his wrist and looked at the time on his watch:

"Half past eleven, forty minutes to go!"

Gu Lu yawned boredly.

For the National High School Mathematics League, one thing Gu Lu especially wants to complain about is that it does not allow early submission.

So back then, after Gu Lu finished the question, he could only sit on the chair in a daze, staring at the invigilator for more than half an hour.

Gu Lu glanced at the silent teaching building, buttoned his sunhat to his face, and found a comfortable position to lie on the back of the chair.

............

"Candidates, please note that there are still fifteen minutes left before the end of the exam time, and there are still fifteen minutes left, please hurry up and answer the questions if you have not completed the exam papers!"

Fifteen minutes before the end of the second test.

Many of the candidates in the exam room began to speed up, and the tip of the pen flew up on the scratch paper for the final struggle.

Of course, there are also some candidates who have completely given up struggling.

Lying on the table with empty eyes, his face was loveless.

In the corner of the classroom, the fine sweat on Bi Qi's forehead couldn't stop dripping, but he didn't wipe it.

"Why, why is it still wrong!!It stands to reason that it should be possible!!"

"Time is running out, no, no, I can't give up!"

Bi Qi cheered himself up.

What he is doing now is the fourth and final question of the second test. This is an elementary number thesis.

The first three questions have already been completed.

Half an hour ago, Bizzie had been working on this last question.

But over the course of such a long time, Bizzie has tried many methods.

But all of them ended in failure!

There are only fifteen minutes left before the end of the second test, and Bi Qi still hasn't figured out any correct solution.

He's in a big crisis!
