Like the mode of the college entrance examination, the first session of the third middle school in the morning also tests the language.

Although Xu Yun hasn't reviewed Chinese these days, as his best subject before, after quickly immersing himself in it under the effect of concentration, he can answer the questions quite fluently.

In addition, he also has a good hand, and he can get a lot of points on the surface of the light scroll.

It took about two hours to finish.

However, due to the fact that the official examination school does not allow the paper to be handed in in advance, he can only look back and forth through the test paper in boredom.

However, there is no intention of checking.

Chinese is different from other subjects, if you are not fully sure, rashly revising the answer will often backfire and replace the correct one with the wrong one, especially affecting the neatness and beauty of the paper, so it is better to keep the original version of the answer.

After eating at noon, Xu Yun slept for half an hour for the first time.

Facing math at its best.

After the exam, Xu Yun got the test paper, first took a general look, and after confirming that many of the questions he had done were the types of questions he had done, he suddenly felt sure in his heart.

"It's a bit difficult, but it's not very high, and it should be able to surpass the score of the last in-class exam."

Whispered softly while immediately filling in the name, class, and test number, opened the sketchbook and began to calculate the first multiple-choice question.

In addition to making him more concentrated, his efficiency in solving problems has also been improved to a certain extent, and with the ability to think abstractly that can only be used in mathematics, it is simply like a tiger with wings. The whole multiple-choice fill-in-the-blank question can be described in two simple words.

Silky.

That's right.

It's silky.

After improving his abstract thinking ability, he can quickly find out the essence of various mathematical problems and solve them with the simplest ideas.

In addition, these days, he has almost asked Su Yushan for all kinds of questions, which can be said to be a lot of accumulation.

Even later on, he began to like the feeling.

Enjoy the satisfaction of conquering each question.

Unfortunately, this process did not last until the end of the exam, and he ran into trouble when he made the final question.

"The finale this time is actually a derivative function, which is a bit interesting." Xu Yun read the question stem and known conditions silently in his heart, and immediately became interested.

Of all the knowledge of high school math, derivatives are an absolute nightmare for every student.

The kind that makes it hard to wake up when you dream about it.

Because compared with the conic curve, which has caused countless people headaches, in addition to the large amount of calculation of derivatives, the key difficulty is that there is no so-called fixed routine, and I don't know what method to use to solve it, so I can only try to do it.

Even if you improve your abstract thinking skills, it will take a long time to make them.

But it was this difficulty that sparked his interest even more.

Only by constantly encountering challenges and completing challenges will the love of mathematics not fade away.

After thinking about it for a while, Xu Yun no longer hesitated, and immediately tried to calculate it in the draft book according to his own problem-solving ideas.

He spent less time on the previous questions, and it was still early to hand in the papers, so he didn't need to be in a hurry now, and he could slowly solve this finale question.

Ten minutes later.

Xu Yun flipped to the next page of the sketchbook full of formulas, his brows furrowed.

"That's not the right solution either."

After trying it himself, he knew that he had underestimated the complexity and difficulty of this question, especially after adding knowledge about triangles, it was simply perverted.

I'm afraid that even the college entrance examination may not be so difficult.

Seeing that the time was passing minute by minute, it was difficult for Rao is Xu Yun to keep the clouds and the wind light just now.

Of course it is impossible to give up, and he does not have these two words in his dictionary.

Faced with such a situation, it seems that there is only one way left.

"Do you really want to use points to get your brain overclocked again?" Thinking about his biggest reliance in his mind, Xu Yun seemed a little hesitant.

Judging from the performance of brain overclocking last time, it is definitely a waste of anti-aircraft guns to fight mosquitoes when it is used to solve problems.

But I was really unwilling to give up a finale like this.

Just when Xu Yun was struggling with this, he saw that the panel took the initiative to appear in front of him, and the information displayed on it made him feel pleasantly surprised.

"Congratulations to the host for completing the advanced task and obtaining the master-brushing achievement, and the task reward has been distributed."

"It's ......"

"I've done a thousand math problems, have I?"

During this time, he was trying his best to complete the task, so that he had already left the initial advanced task behind, and he had not taken the initiative to check the progress of the completed math problem. Immediately quickly controlled the consciousness to turn off the prompt information to find out the attribute page, and saw that the points were successfully increased by fifty, and the reward of increasing the abstract thinking ability by fifteen percent, the self-confidence reached the peak again.

Since it is difficult to solve this problem by increasing 15 percent of your abstract thinking skills, try 30 percent of the effect.

Thinking like this in his heart, Xu Yun decisively used this reward in the next second.

With the refreshing sensation at his temples resurging, his abstract thinking skills managed to increase to 30 percent.

The whole person's thinking about mathematics has undergone a qualitative change.

When we put our attention back on the finale, the original obstacle was instantly overcome.

The idea of solving the problem becomes clear.

"Isomorphic collocation is used in scaling, and derivatives are sought many times, so it should be no problem." Xu Yun checked the calculation in the sketchbook for a few minutes, and finally breathed a sigh of relief when he saw that the final export was successful.

It wasn't until the whole process was written on the test paper that I was in the mood to look at the other candidates around me.

Obviously, he felt that he was not the only one who felt the difficulty of the finale.

A casual glance at the glance can see a nervous, irritable and collapsed look on his face.

Even when it came time to hand in the papers, most people were still reluctant.

The obvious finale was not made.

Xu Yun asked the invigilator to take the test papers, took his things and walked out of the examination room, and stood at the guardrail waiting for Li Hui next door to come out.

During this period, when someone passed by, the most heard was the finale question.

"The finale of mathematics this time is really perverted, almost all the types and knowledge points of derivatives are summarized, and I just gave up halfway through the calculation."

"It's all the same, and I don't know who came up with this question."

"I'm afraid that this time the math score will not be high, and the score of a finale question will be lost."

"Don't worry, everyone is the same anyway, I just asked a friend in the key class, and there is basically no complete one."

Knowing that many of the top students in the key class were planted on this question, Xu Yun was a little moved, and he didn't know what kind of scene would be there when the results were announced.

Just thinking about it makes people look forward to it.

Just when he was secretly happy to make this finale question for himself, suddenly an arm was wrapped around his neck, and a familiar voice sounded in his ear: "It's better that you handed in the paper early, and there was a girl on our side who didn't hand in the paper, and was directly scolded and cried by the invigilator." ”

Hearing this, Xu Yun turned his head to look at Li Hui and said with a wry smile: "Is there a possibility that she didn't cry because she was scolded?" ”
