As soon as Liu Linna's words fell, everyone was shocked.

You know, if the difficulty of the A paper is easier than the international paper, then the B paper is basically the standard IMO paper.

Even in international competitions, the prescribed time for answering questions will not be less than five hours, and Liu Linna actually completed the difficult B paper in less than two hours after completing the A paper, which is obviously beyond everyone's expectations!

"Eh, it's good!" Qin Pengfei nodded approvingly when he heard this, and motioned to the invigilator to put away Liu Linna's exam papers.

After the two invigilators got Liu Linna's exam papers, they quickly compared the answers, and then showed surprise on their faces, and then walked up to Qin Pengfei's ear and whispered a few words.

"Liu Linna, you have successfully passed today's exam. After hearing this, Qin Pengfei smiled, and then said: "It's a little late today, you are doing very well, you can go back and rest first." ”

"Teacher, aren't there still two sets of papers?" Liu Linna looked at the other two sets of difficult exam papers on the podium, and then said, "I want to try it." ”

"This ...... Okay!" After Qin Pengfei finished speaking, he took another exam paper from the podium and handed it to Liu Linna.

"Thank you!" After taking the exam paper from Qin Pengfei's hand, Liu Linna smiled slightly, and then continued to answer the paper.

"Ladies and gentlemen. At this time, Qin Pengfei looked at the watch on his wrist and said: "There is still an hour before the lights go out in the school dormitory, so I will give you the last half hour to answer the paper, and collect the paper on time at ten o'clock, and the exam results will be announced tomorrow, do you understand?"

"Uh, it means...... There is still half an hour to answer the question?" Duan Yun, who had been engrossed in solving the question before, only then did he react from his thoughts after hearing this.

"Yes, no matter how much you write in half an hour, it will be rewinded. Qin Pengfei glanced at Duan Yun, then frowned, and reminded: "Duan Yun, you have to come on." ”

Obviously, in Qin Pengfei's opinion, Duan Yun's performance today is not ideal, after all, except for him, everyone else has successfully completed the A volume, Liu Linna has even finished the B volume, and Duan Yun has not even completed the simplest A volume, this gap is obviously a bit big!

"Uh. Duan Yun nodded when he heard this.

By this time, he had already solved the penultimate question in the A paper.

Of course, the answers to the A paper written by Duan Yun are all answers that have gone through streamlined steps, and if he just wants to find the result, this exam paper will not be difficult for him at all.

It's just that now the allotted time is almost up, and there is not much time left for him to 'splurge'.

Moreover, the decisive role in this exam is the score, no matter how perfect Duan Yun's steps to solve the question are, it is just useless work, so seeing that the exam is about to end, Duan Yun decided to solve it quickly!

Thinking of this, Duan Yun immediately raised his head, beckoned to Qin Pengfei, and said:

"Director Qin, can you give me the rest of the exam papers?"

"You...... You mean all the rest of the exam papers?" Qin Pengfei asked in surprise after hearing this.

"That's right. Duan Yun nodded, and then said, "Time is running out, I want to answer all the papers directly." ”

"Stupid!"

As soon as Duan Yun's words fell, the other two boys in the Olympiad group snorted coldly with disdain.

And the two teachers who invigilated the exam also shook their heads with a smile when they heard this.

The thing is obvious, no one would believe that Duan Yun can complete four Olympiad exam papers in half an hour, which is almost impossible.

After all, this is the exam paper of the Olympiad, which is much more difficult than the general exam, and even if the IQ is as high as 173 Liu Linna has only answered two papers in nearly two hours now, and Duan Yun wants to complete the remaining three more difficult exam papers in thirty minutes, which is tantamount to a fantasy in the eyes of outsiders!

Even Yang Ying, who had the most 'iron' relationship with Duan Yun, saw this situation, and a touch of gloom flashed in her eyes, obviously she didn't have the slightest confidence in Duan Yun.

"This ......" At this time, after hearing Duan Yun's request, the two invigilators all looked at Qin Pengfei.

"Give him all the rolls!" Qin Pengfei said after a deep sigh.

Subsequently, the remaining three sets of exam papers were sent to Duan Yun.

The exam continues.

Liu Linna, who had already begun to answer the C paper, seemed to have finally shown embarrassment on her face, her willow eyebrows furrowed slightly, and she fell into contemplation after only half of the first question, obviously the difficulty of this C paper had exceeded her expectations!

Liu Linna was stuck in the puzzle, and the others seemed to be in trouble too, Yang Ying was stuck in the last question of the B paper, and was repeating the columns on the scratch paper, which had filled three full sheets of scratch paper!

As for the other two boys, they were also stuck in the second question of the B volume at the same time, and they were all worried, only occasionally when they looked at Duan Yun, their faces showed a little happiness.

Time passed minute by minute, and everyone tried their best to try their best to get to the highest level, only Duan Yun looked a little absent-minded, just drooping his eyelids, and wrote a string of formulas on the paper without hurry.

At this time, the atmosphere in the multimedia classroom seemed a little dull, the two invigilators were already standing at the door, talking about something to each other, while Qin Pengfei was standing by the window, looking out of the window, as if he was thoughtful.

Feeling that the invigilator was a little lax, Yang Ying suddenly coughed dryly, and then pushed her exam paper in the direction of Duan Yun.

When Duan Yun saw this scene, he didn't mean to plagiarize at all, he just smiled and shook his head.

"Ding!"

With a soft sound, the hour hand of the quartz watch on the classroom wall finally pointed to the direction of ten o'clock, and Qin Pengfei and the two invigilators at the door came to the five candidates again.

"Ladies and gentlemen, when the time comes, put the exam papers on the table and you can leave. Qin Pengfei said loudly.

"Wait a minute!" As soon as Qin Pengfei's words fell, Duan Yun and Liu Linna raised their hands at the same time and said.

"What's wrong with you two?" Qin Pengfei asked with a frown when he heard this.

"Give me five more minutes!" Liu Linna said with a frown.

"I'll finish it in three minutes!" Duan Yun said without raising his head.

"Okay, hurry up, the dorm lights are going out soon. Qin Pengfei looked at his watch and said.

"Rubbish! You won't be able to finish it in three more hours!"

"I haven't finished the first exam paper until now, it's rubbish!"

When the other two boys left again, they saw that Duan Yun was still writing the last question of the A paper, and whispered sarcastically.
