The school goddess, she becomes more and more beautiful

Chapter 222

On Saturday morning, the teaching building of Peking University School of Mathematics.

At eight o'clock in the morning, the National Preliminary Examination will start here.

There are only three questions in the preliminaries and finals, and they are all subjective questions.Each question is worth 21 points, and the total score is 12 points.The exam time is from 30:[-] to [-]:[-], a total of four and a half hours.

From the regional preliminary competitions to the provincial competitions and then to the national competitions, there are fewer and fewer questions on the paper, and the total score is getting lower and lower, but the difficulty is also increasing.

The test questions on the first day did not involve geometry. The first question was about sequence, and the second and third questions were all proof questions.

During the training camp, Song Ranran practiced too many of these types of questions. After getting the papers, the questions generally went smoothly, except that he spent a little more time on the third question.

Because the process is very important in the solution of proof questions, even if the proof is not proved in the end, you can get step points if you write the key points.

In order to get full marks, participating students should try their best to write logically clear and complete steps in solving problems, and no matter which method is used to prove it, it must be rigorous.

Song Ranran did the first two questions relatively quickly, leaving plenty of time.

According to the question stem, try to infer on the draft paper now, and after proving that the method is indeed feasible, write it on the answer sheet step by step.

An hour and a half before the end of the exam, Song Ranran stopped writing.

At this moment, her team members are still answering questions.

Time passed, and after twelve o'clock, Jiang Ye and Yue Wenyan also stopped answering questions.

From the looks of it, the situation shouldn't be too bad.

An exam lasted from morning to noon, and it was finally liberated after the invigilator collected the papers.

When Song Ranran led the team members out of the teaching building, the teacher who had been worrying all morning immediately stood out from the crowd, and led them back to the hotel step by step like a mother chicken who spread her wings to protect her chicken cubs. rest.

"You must be tired after taking the exam for so long, go back to the hotel to rest first. I called to order lunch, and it will be delivered later."

While talking, the coach secretly observed everyone's expressions after coming out, hesitant to speak.

As the leading teacher in charge of them this time, he must still want to know how the exam is going to be.

But I am afraid that I will put too much pressure on the students after asking directly.

After holding back for a long time along the way, when he returned to the hotel, he still couldn't hold back and quietly pulled Song Ranran aside.

"Ran Ran, how do you feel about today's topic? Do you have any questions?"

Seeing the girl shaking her head, the coach was half relieved.

The Olympiad exam is a very energy-consuming thing. After lunch, the coach asked the students to sleep well during the lunch break. They gathered at [-]:[-] p.m. to discuss today's exam questions and analyze the possibility of advancement.

There were only three questions, and after writing them down from memory, the coach and the students discussed the answers together, and Rong Zhou also participated in it.

Although they are coach assistants, the players are actually not very familiar with Rong Zhou.

But in the link of problem solving and discussion, they really felt the efficiency of learning gods.

The national competition exam lasted four and a half hours. Some people didn't finish the exam until the end of the exam. They gave all the answers in less than two hours, and there was more than one method.

Everyone matched the answers with each other and roughly estimated the score.

Song Ranran is all right, full marks should be no problem, as for Jiang Ye and Yue Wenyan, although the proof of the third question is not complete, they still have three to five points for the steps. lower.

As a rough estimate, their team has at least 101 total points.

Compared with last year's results, this score is not a big problem for entering the country this year.

　To be honest, Zhao Zhao hasn't studied mathematics for four years, and reading math problems is like a scripture.But I actually like mathematics very much, and I really envy people who are good at mathematics.
