From all-round academic master to chief scientist

4.5 hours is a long time or a short time, but for students taking the exam, these hours are not particularly sufficient.

Otherwise, the difficulty of CMO cannot be written casually. Three questions and 4.5 hours seem to be very ample, but obviously for most candidates, they still have to cry that this time is too long. Anything less is simply not enough.

Moreover, this year is an odd year. According to past practice, the questions in odd years are more difficult, while the questions in even years are relatively easier. Therefore, the difficulty of this year's test questions is quite high, and some people may not even get one Can't get any points.

According to common sense, as long as you participate in CMO, you will at least get a bronze medal. However, there are always a small number of candidates every year who cannot even get a bronze medal. It is because their performance in the exam is really poor. Otherwise, if they get 0 points If you can get a bronze medal, wouldn't it be too easy to get this bronze medal?

Therefore, in the examination room, every student was racking his brains to write the questions. As a result, almost all of the more than 300 contestants this year fell into deep thinking.

Except for a few students, such as Lin Xiao.

When Lin Xiao got the test paper, he didn't bother to read the questions at the end and just started writing the first question.

There were two short questions in the first question. The first question was an instant kill, and then the second question, after thinking about it for a while, Lin Xiao quickly solved it.

"Send points."

Lin Xiao, who came to this conclusion, estimated the time and estimated that it only took him thirty minutes to solve it. I believe that for most contestants, it would not be a big problem.

Soon, it was the turn of the second question. This question was a bit interesting. It was much more difficult than the first question. It was a question that directly combined algebra, three-dimensional coordinate system, and geometry.

However, looking at its essence, Lin Xiao quickly analyzed the routine of this question, which was nothing more than thinking in the order of one dimension, two dimension and three dimension, so he solved it quickly.

"It's better to send points."

Then there is the third question. This question is a good question because Lin Xiao came up with a very brilliant way to answer it. The answer is short and simple, but it is difficult to think about it and there are quite a few pitfalls.

But all in all, he managed it easily.

"They're all giving points anyway. This Olympiad isn't difficult at all."

Shaking his head, he sighed inwardly: "I should be considered a terrifyingly strong math expert now, right?"

In this way, he finished all three questions on the first day. He looked at the time and saw that there were still two and a half hours left. This meant that he only spent two hours to solve the problem that took four and a half hours to solve. Three questions solved.

Looking back at the students around me, most of them are still burying their heads and sketching on the draft paper. Some are even struggling with the first question, some are still solving the second question, and a few have achieved the third question. There are three questions, but obviously, the third question has a certain degree of difficulty. Most of the students who wrote the third question have not found the idea yet.

You must know that these students are all mathematics masters in the eyes of their classmates in their own schools, and they are all ranked among the top 300 mathematics geniuses in the country at the middle school level this year.

But now, they all seemed to have turned into ordinary candidates, tortured by the test questions in excruciating pain.

Only Lin Xiao is not an ordinary candidate no matter what level of exam he takes.

Now that he is used to doing this kind of competition questions, there is basically nothing to say about taking this kind of test again. It is no problem for him to be a proposition group or something. What did the proposition person think when he asked this question? He can guess it all.

Finally, he spent a rare half hour checking it from beginning to end. After confirming that there was no problem, he stood up directly and handed in the paper.

Teacher Ding doesn't care whether he submits the paper in advance or not.

After hearing the sound, all the candidates present couldn't help but look at Lin Xiao, with surprise and confusion in their eyes.

Why did this person hand in the paper?

Finished?

Or gave up?

Some candidates were not affected by Lin Xiao and were only briefly distracted before starting to write the paper again, while some candidates became nervous and anxious.

However, these things are not what Lin Xiao should consider.

The invigilator was naturally surprised when he saw Lin Xiao handing in the paper so early. Then he was even more shocked when he saw Lin Xiao's neat answers.

It only took this student two and a half hours to finish all the questions?

An invigilator looked at Lin Xiao's answers, and then quickly stopped his eyes to avoid being hit by an IQ reduction, because he couldn't understand it at all.

These invigilators are all teachers from this school and are not necessarily mathematics teachers. Of course, they cannot understand the questions of this kind of mathematics competition.

He could only lament that these people who are good at mathematics are simply more outrageous than the last.

…

Lin Xiao handed in the paper and returned to the meeting point.

There weren't even a few people at the meeting point.

After searching for a while, he finally found their two leading coaches.

What surprised him was that the two mathematics professors were actually playing chess, and he didn't know where the chess came from.

However, Professor Zhang was obviously not as skilled as Professor Huang. When Lin Xiao came over, he saw Professor Zhang knocking out Professor Huang's soldiers with a single chariot. However, he didn't notice Professor Huang's horse was right next to him, so he just walked away with it. , killed him.

"Hey, hey, I made the wrong move." Professor Zhang immediately regretted his move.

Professor Huang immediately opened his hand and said with a smile: "You will have no regrets."

Professor Zhang couldn't help but scratch his head. This was his last rook. Now that it was gone, he only had one knight and two cannons left. On the other hand, Professor Huang still had many chess pieces.

At this time, he raised his head and saw Lin Xiao coming. His eyes lit up, and he stood up and said, "Hey, classmate Lin Xiao, you have finished the exam."

Then he pushed the chessboard and said: "Lin Xiao is out and won't play anymore. This game counts as a draw."

Professor Huang suddenly blew his beard and glared: "Hey, you old guy! How can it be considered a draw if I have two more cars than you?!"

Lin Xiao, who was standing next to him, couldn't help but feel funny when he saw this scene. He really didn't expect that Professor Zhang actually had such a cheating side.

Professor Zhang also knew that Lin Xiao had seen him, so he kept silent about the chess matter and asked directly: "How was the test? Is the question difficult?"

Lin Xiao said: "It's okay."

"So how did you do? How many points do you think you can get?"

Lin Xiao said: "You should be able to get full marks, right? The questions are a bit simple after all."

"The question is simple?"

The two professors looked at each other. This year is an odd year, so the questions should be more difficult. Lin Xiao said it was easy?

At this time, Professor Huang suddenly looked at the time and was stunned again: "Hey, isn't there still two hours until the exam is over? Why did you come out?"

"It's finished, so it's coming out."

"You finished it in two and a half hours? Have you checked?"

"It took half an hour to check."

The two professors looked at each other again.

And it took half an hour to check?

Worthy of being a student with perfect scores in the league.

Awesome.
