Because you will find that it is very likely that you will not be able to do this question yourself until the paper is closed.

The smartest way is to finish the questions you know first and check them two or three times.

This will give you a chance to get a higher score.

I have to say, don't look at Yun Yan's temperament, as if he doesn't care about anything.

But she also has the common problem of being a scholar, and she can't take her eyes away when she sees a problem.

But Yunyan can better distinguish the priorities of things, for an exam like imo, which has only a full score of 42 points.

Fault tolerance is extremely low.

A point will be deducted for the slightest mistake.

She weighed the difficulty of the first two questions and chose to start from the second question.

The knowledge points of this question test are very clear. Although there are pits in the question, you can see the general idea after reading it several times.

Yun Yan first calculated on the performance paper.

Half way through, there is no answer.

At this time, more than twenty minutes had passed.

Seeing that half an hour had passed soon, Yunyan felt that she was really nervous and wanted to sweat.

However, the temperature in the examination room was excellent and there was no wind.

She is sweating now for no other reason than panic.

Yunyan went to look at the topic again, this time, she found a pit in it again.

A new hole that didn't appear in the previous exercise.

Yunyan couldn't help rubbing her forehead, she sighed, what kind of luck she is.

The first question was "hit luck", and the most difficult of the three questions was chosen.

Teacher Zhang said before that the shortest and least demanding questions have a 20% chance of being simple questions.

Most people can get points in this case.

After all, the short title means that there may be fewer pits.

If there is a big hole in such a short question, it can only show that the level of the questioner is high.

Can ask, will there be low-level question-makers in the imo committee?

There are six questions every year, and even the questions are just finished every year, and the whole world is scrambling to imitate similar questions.

Practice for your own students, and practice makes perfect.

Therefore, the level of the questioner has long been honed.

Yunyan couldn't help sighing in her heart, she spent another hour to finish this problem.

After checking the answer and finding it correct, it took another 13 minutes to transcribe the answer sheet.

At this time, she went to the first question very quickly.

Even the third question, which didn't understand very well at first, was easily solved when read it at this time.

After all, the question is long and the amount of information given is large, which makes it easy for people to draw the test center within a certain range.

Then, according to the test site, it is deduced that the questioner wants to examine everyone's content.

In total, it took 103 minutes for Yunyan Sweep and Calculation to transcribe the second question.

The first question only took 28 minutes.

For the third question, Yunyan also spent 79 minutes because it wanted to deduce the intention of the questioner.

After finishing a set of questions, she spent a total of three and a half hours.

When brushing the questions, Yunyan was distracted.

After finishing the questions, I looked up and saw that the surroundings were almost empty.

Yunyan: "..."

Shocked, everyone is doing the questions so fast?

Yunyan checked the answers twice, including every basic formula written on the answer sheet.

After everything was correct, there were still more than 30 minutes before the exam, she raised her hand and handed in the paper.

At this time, there were only about half of the people in the exam room.

Teacher Zhang and other teachers from Hua Guo were sitting in the cafe opposite the examination room.

More than 20 teachers occupied most of the cafe.

Teacher Zhang asked everyone what to drink and what to eat as snacks.

The answer: "Just like you."

Anyway, can't tell the difference if drink it.

Besides, Europeans like sweets, and the dishes and cakes are very sweet.

These days, teachers have refreshed a lot of cognition by ordering food by feeling, and decided that it is better not to step on the thunder.

The walls of the cafe are made of glass, and the teachers all sit by the window just to see when their students come out.

The exam took place at eight o'clock, and around eleven o'clock, a bunch of people came out of the exam room one after another.

The teachers trembled.

"Are they doing the questions so fast? This, this is only three hours. Only Yunyan in our team has this speed."

"Don't, don't, don't panic. They do the questions quickly, which doesn't mean the accuracy rate is high. Mr. Zhang has been leading the team for several years. Let's ask Mr. Zhang about the situation."

Teacher Zhang covered his face, and Teacher Zhang said that he did not want to speak.

"Old Zhang?"

"Mr. Zhang, what's the matter with you? Are you not feeling well?"

Teacher Zhang is determined to share the discomfort with everyone.

"In previous years, they also used the same speed. But in general, their total score in two days was around 25 points, and they didn't have to run for the silver medal."

"..."

After the silence, one of the teachers murmured, "Why don't you take this to heart, old Zhang?"

Teacher Zhang said, "Don't worry, I'm not panicking at all this year. We have Yunyan and Xingwei, and the other four students are not bad at all."

Two gold medals and four silver medals.

He added, "Besides, those contestants who really get high scores in the test every year answer the questions and check them until one second before they are closed. Foreigners who answer half of the questions and leave, generally don't have particularly high scores."

Teacher Zhang's voice just fell.

I saw a very familiar figure coming out of the building opposite.

Also wearing the national team uniform of China.

Who else could it be if it wasn't Fang Yunyan?

Teacher Zhang shook his hands and spilled the coffee.

Then he hurriedly said, "Bah ah, crow's mouth."

Yun Yan is actually quite a character of 'do as the locals do'.
