I Am the Sister of the School Grass

After Yunyan got through the phone, she felt relieved.

She talked to Yuan Mo for a while, then hung up. Arms stretched out to put the phone on the side table next to him, and get ready to rest.

The roommate next to her is trying to keep up with Yunyan's work and rest habits recently.

After all, everyone knows that Yunyan and Wei Ge are the main players of the io national team this year.

The io exam is not a team competition, although it requires six players from each country to participate.

Individuals.

In other words, this competition is based on individual performance.

Whether you can get a gold medal is also a personal reward.

It's just that the 'individual' represents the country.

So every time it comes into the country, it says 'my country won the International Mathematical Olympiad Gold Medal', which sounds like a group award.

This is also a misunderstanding of the public.

This year's main venue is in London, and the exams are scheduled for July 18th and 19th.

There are two days in total. The test starts at 8:00 in the morning and ends at 12:30 noon, and the test is continued for two days.

Unlike the o finals, the total score of io is 42 points.

There are six questions in total, and each question is worth seven points.

In this way, one less point may drop ten or even twenty places.

It is not cruel.

Yunyan slept for more than 20 minutes and got up, washed her face and continued to go to the study room of King's College next door to study the questions.

The roommate went with her.

Yunyan was a little puzzled, "Aren't you going to sleep for a while?"

The roommate shook his head wildly, indicating that he wanted to accompany Yunyan.

Yunyan knows that roommates are the kind of scholar who don't have the word 'lunch break' in the dictionary.

Recently, the reason why I can go to bed with her every day after eating is purely because my roommates have no pressure in their hearts.

She's just a backup anyway.

From the current situation, the six players of the national team are in great shape, and they don't seem to be under too much pressure.

It should not be her turn to play.

Yunyan's roommate said more than once, "I'm here to accompany the prince to study."

Yunyan: "…"

Yunyan thought, she is not without pressure.

Just don't want to put the pressure on my face, because it will put more pressure on the other five people in the national team.

—Everyone is counting on her for gold.

If she herself is so stressed, others will not learn to go crazy.

The pressure of the cloud and smoke comes from the recent roll.

She swiped two sets of previous years' examination papers in a few days, and was graded by two leading graders in her country.

A perfect score of forty-two would give her about thirty.

The teachers are very satisfied with this result.

"No surprise, absolutely gold!"

Yunyan herself is not satisfied, and it is not that she does not know these questions.

She figured out the answer and wrote all the points that should be written.

No matter how you look at it, it is more than thirty-one points.

In the discussion room, Yunyan picked up her own paper.

Looking at the '5' written by the marking teacher after the first question, the whole person fell into a deep suspicion.

She first calculated it by herself, and then compared it with her own answer.

Yunyan pushed the paper over, "Teacher, why is this question only five points?"

In the io exam, the test papers issued by the io committee are generally in the common language.

English, French, German, Russian, etc.

Chinese is not included in the common language of the io test paper.

As for countries that are not included in the lingua franca, two mathematicians will lead the teacher to translate and send them to the students to do the questions.

Correspondingly, the scoring is also conducted by leading teachers from various countries to assist the teachers of the committee to assess together.

After all, math knows no borders.

The teachers of the committee don't want to bury the math genius because of the 'language barrier'.

Therefore, the scores of the two leading teachers in each country must be objective and fair.

Now it is also to make the students adapt to io, and the two teachers who lead the team are also conscientiously marking the students.

It can be said that the current results are actually not much different from the results of the official examination room this year.

As long as there are no major problems before the exam, this score basically represents the individual's io score.

Yunyan is a bit incompetent because she knows this truth.

Her goal is not just gold!

Yunyan has so much ambition, she wants to be the first in the exam, and she wants to win more glory for the country.

However, the idea of ​​Yunyan has not been told to others.

After all, looking at the huge '31' on his roll, this idea is no different from bragging.

The teacher took Yunyan's test paper and circled two points with a red pen for her.

"These are deductions."

Although the teacher knows that you write here just to help you calculate the answer.

But she will affect your roll score.

Yunyan: "…"

I don't know what to say.

She smeared it out with a black pen, looked at it, and crossed out several lines of formulas.

She raised her head and asked the teacher, "So? Is it a perfect score?"

The teacher looked at Yunyan with a 'you're too naive' look, and showed her the English version of the exact answer.

Although these are mathematical formulas, but in English, there will be prompts on what points to calculate in each line.

"This may be a question of your habits. Many students in China like to memorize some specific answers. Therefore, you have not written all the steps of this calculation."

The teacher pointed to the line crossed out by Yunyan and said,

"This formula should not be used here. This is an advanced version calculated by the teacher of our training team. You need to write the original formula. Of course, the space is limited, so you don't need to write the derivation process."

Yunyan: "…"

I really don't get graded by Daniel teachers, and I don't know where I am wrong.

Qian Xingwei also scored 31 points on this paper, but he wrote all the points that should not be lost like Yunyan.

She deducted points because she couldn't figure out the last question.

Qian Xingwei said, "In fact, these things were mentioned during the time you didn't come, but Mr. Zhang thought it was not important, so he didn't mention them to you later."

After all, the most important thing is to calculate the results.

Who cares if the formula is the original version, or is it derived?

Qian Xingwei comforted, "Don't worry about this, it can be adjusted in a day or two."

At that time, Yunyan will add these deductions to…

Isn’t that all thirty-three points? !

Yunyan seemed to know what Qian Xingwei was thinking, she pointed to her second question.

The deduction point is still in the formula.

In fact, Yunyan did not deliberately recite these derived formulas.

She really knows these formulas by heart.

Seeing that this step is more convenient to use the advanced version of the formula, I wrote it down.

I don't know, this is a pitfall.

The teacher said, "You can use these formulas, but you can't write them directly on the volume. Because no scientist has come up with this formula, you have to prove it after you write it down. It's too much of a loss."

Yunyan nodded, the teacher took her test paper and marked each deduction point.

"Student Yunyan, if you don't deduct points from the formula, your total score on this paper is 39 points."

Qian Xingwei was shocked.

After a pause, the teacher's next sentence was, "It's even higher than last year's highest score."

Yunyan's heart was suddenly full.

She feels that her wish to take the first place this year is probably, can, and will come true!

In this way, Yunyan redoubled her studies for ten days, and finally came the day of the exam.

July 18, 2020.

The marking teachers have been 'isolated' from the students since the afternoon of the day before yesterday.

Cannot communicate with the outside world.

After translating the test paper, listen to the teachers of the committee explain the detailed rules of the paper.

For this big exam, the Queen of Corruption even sent her own soldiers to guard the exam room.

Avoid all practices of favoritism.

Yunyan got up early in the morning and took out the national team uniform that had been prepared for a long time from the closet.

Get dressed and tie up your hair.

She was just packing when she heard a knock on the door.

"Get up quickly and go to the second floor for breakfast."

After finishing speaking, the footsteps gradually faded away, and it looked like they were knocking on another door.

Breakfast is provided by the teachers who lead the team from each country and tell the committee what they want.

Therefore, a beautiful landscape appeared in the dining area on the second floor.

Others eat toast, sandwiches, fried eggs, fried bacon, and milk oatmeal.

The Chinese team members eat fried dough sticks, scallion pancakes, and drink soy milk.

The scallion pancake is delicious with a little appetizer.

Not much fun.

"Do they do this every year? I heard that they haven't won a gold medal in eight years."

"No, it's like this every year, and I don't know what kind of mountain and sea delicacies they eat."

Yunyan could understand, she looked at the scallion pancakes and mustard on her plate.

I thought, this is the delicacy of mountains and seas in the eyes of foreigners?

After eating, it was only fifteen minutes past seven.

Students stood in a line and walked quietly to the examination room.

The teachers stayed where they were. After the students entered the examination room, they followed behind. They did not enter the examination room, but waited outside.

After entering the teaching building, Yunyan found her own examination room, waved with her companions behind her, and entered directly.

io competition, six people from each country will be arranged in different test rooms.

After the exam is over, teachers in your country will assist the committee in marking the papers.

There are blacks, whites and yellows around Yunyan, and everyone doesn't look at the others.

Sit in your seat and wait for your curls.

Yunyan's heart is beating wildly.

It was stretched from forehead to lips.

She thought of how she imitated Mexico's refueling handwriting on the scratch paper during the o exam.

But Yunyan thought, no need this time.

Really.

She will panic, but more confident.

She has the strength - take the first place.
