Then Liu Xu also nodded at the blonde professor, and then ignored the others, and also looked at the test question in front of him carefully.

Fortunately, this time the test paper was taken by Xiangya in the past, and the live broadcast camera did not pay attention to it here, if Liu Xu went over to ask for it in person, he would become the focus of the camera again if he wanted to come here, this kind of thing to steal the limelight of Ole and others is not what Liu Xu wants to see, after all, today Mo Tengting, Ole and others are the protagonists of this exchange competition.

After that, Liu Xu put all his mind on answering the questions, first looked down at the test paper there, and then picked up the pen next to him and wrote and drew there, until more than two hours later, Liu Xu raised his head with satisfaction and chuckled.

"Hmm, when did Concubine Su Chen and Cao Wanshui leave?"

Liu Xu was too engrossed in the question just now, and he didn't even know when Su and Cao would leave, obviously the two girls didn't want to disturb him, but at this time, seeing that the two girls were not there, he curiously asked Xiangya who stayed beside him.

Seeing Xiangya, who Liu Xu was asking at this time, she couldn't help but smile and said aloud, "Senior Sister Su left not long after Senior Brother did the question because she needed to deal with something personally, and Senior Sister Cao left half an hour ago, and it still has a selection competition to participate in!"

Liu Xu, who heard this, couldn't help but nod there with a smile, and then didn't say anything, but at this time, Xiangya was a little curious and asked out loud, "Senior brother, have you done all these topics?"

"Uh-huh, why don't you show me what's right or wrong?" At this time, Liu Xu said with a smile, but Xiangya, who heard this, couldn't help but roll her eyes there, although it is true that he is a top student at Beijing University, but this exchange competition test paper, he is really sure that he can make it, and there are only three questions, obviously this senior brother is deliberately teasing her.

However, Liu Xu ignored his expression, but looked at Mo Tengting and the others who were still doing the questions below, but after seeing that Mo Tengting and Ole were already smiling at this time, Liu Xu at this time also nodded secretly, and when he was just doing the questions, Liu Xu also secretly assessed the difficulty of these questions, generally speaking, it was not as difficult as the questions when he communicated with Ole in the competition, but they were also equivalent to the difficulty of the questions in the International Mathematics Competition.

However, in Liu Xu's opinion, these questions are not too difficult for Mo Tengting and Ole, and I believe that as long as they play normally, a full score is possible.

As for the others, although they seem to be frowning a little now, but according to Liu Xu's guess, ninety percent of the questions should not be a problem for them, after all, those who can come here are naturally all frequent visitors to the International Mathematics Competition, and they are not a few of them dealing with this kind of difficult question, and the key to really determining the remaining six promotion places is to see how they are in today's state.

Another half an hour passed, and the bell at this time also remembered again, which also means that this math selection competition is over, and then, of course, it is the on-site correction.

In order to ensure the fairness of this exchange competition, the correction of this selection competition is under the camera, which is why the five invigilators who came this time are all at the level of mathematics masters.

At this time, Mo Tengting and the others, after finishing the questions, naturally saw that they had not left De Liu Xu, and after the test papers were handed in, they came directly to Liu Xu.

"How do you feel like you're playing?"

After seeing everyone's arrival, Liu Xu couldn't help but ask there with a chuckle.

"It's not difficult!"

Naturally, Mo Tengting said this, but obviously this is also in line with Liu Xu's inner thoughts, and this topic is difficult for Mo Tengting.

"I don't have much confidence in one question here, but overall it shouldn't be a big problem!"

At this time, the man who praised Haikou in front of Liu Xu and others before the selection competition couldn't help but say it there, but Liu Xu, who heard this, nodded there with a smile, so it seems that this kid does have the strength and qualifications to say what he just said.

In this question, there are indeed three questions that are much more difficult than the others, obviously these three questions are also the key to determining which of them can break through the selection competition, since this kid only has one question that is uncertain, then if the other questions are okay, his chance of passing the selection competition accounts for at least 90%.

"I also have a topic that I'm not sure about!" said the only girl among the five people who participated in this selection at this time.

And when the girl said this, her expression was also extremely relaxed, and she obviously had a lot of confidence in being able to break through the selection competition this time.

However, Liu Xu, who heard this, couldn't help but look at her there, and really didn't expect that this extremely cheerful girl would play so well.

"I'm not sure about two things!"

"I'm not sure about two too!"

The remaining two people were a little frustrated at this time and said there, the two questions are not sure, although it does not mean that they have no chance to enter the finals, but one thing is certain, this probability will not exceed thirty percent at most, which is equivalent to a semi-judgment, they are already out of this exchange game, and Liu Xu, who heard this, couldn't help but comfort two sentences there, after all, Liu Xu also understood in his heart that failure in the two questions is equivalent to putting the initiative on others.

"What is this?"

At this moment, the only girl among the five suddenly said loudly, and the others, after hearing this, also looked towards Liu Xu, but at this time, Xiangya, who heard this, couldn't help but laugh and said, "Everyone, do you want to score here?"

After hearing this, everyone sitting here couldn't help but be stunned at first, and then couldn't help but be happy, and then squeezed directly towards Liu Xu, all wanting to see if the things on the desk were what they had guessed in their hearts, and even during this period, someone almost squeezed Liu Xu aside.

But when it was determined that the thing on the desk was the test they had just done, someone hurriedly shouted, "I'll take a look!

And the person who shouted was one of the two men who showed a depressed look just now, obviously he wanted to see Liu Xu's answer at this time, and compare it with his to determine whether he had some good luck, so that one of the two uncertain questions was answered correctly.

"Alas, question 13 is still wrong!"

But it didn't take long for the man to sigh and say, and after hearing this, the other man also frowned slightly, obviously his answer was also very different from what Liu Xu answered.

"It's really good luck! It seems that the thirteenth question should be stable!" And the only woman who participated in this selection couldn't help but say excitedly, and after hearing this, the faces of the two men just now became even more bitter.

"What I did may not be right, maybe, my answer is still wrong, you are right!" At this time, Liu Xu no longer knew how to comfort these two guys, so he could only say so at this time, hoping that their mood could be adjusted somewhat.
