In fact, Yunyan doesn't have high requirements for the accommodation environment. For the past seventeen years, she lived in the compound with her grandparents.

Lighting is trivial.

There are also couples fighting at night, beating children, or watching TV at night.

Because of quarreling with roommates about this kind of thing, Yunyan hasn't been so leisurely yet.

Yunyan faced the wall, brewing drowsiness.

Chen Ling took the things that Yunyan gave him, looked at Zhuo Feilan, and said mockingly: "I didn't see that everyone was asleep, and I'm still writing the gauntlet here. You don't let us sleepers turn off the lights, we will bear it, but you Don't make us rest."

Having said that, Chen Ling also took a bath and came back to rest.

She thought, Yun Yan was right, staying up too late would indeed affect the efficiency of attending the next day.

Really want to learn, not less than an hour.

Early the next morning, the girl who didn't know what time she went to bed for two nights at No. 3 Middle School was no longer in the dormitory.

Yunyan went to the classroom to see them.

Yun Yan and Chen Ling were both shocked by this.

- Don't these two need to sleep?

But they didn't study at the moment, but said to another person: "You ask me why Fang Yunyan didn't come, and you want to ask her a question? You don't know, the provincial number one was going to bed at eleven o'clock yesterday. Maybe she hasn't done it yet, but I wrote it until two o'clock and finished it."

As soon as Yunyan sat down in her seat, she heard the man say.

"Your answer is right, but the process is wrong. This step cannot be counted down like this."

Zhuo Feilan: "...impossible...really...isn't it?"

See Fang Yunyan coming.

The classmates on her left approached her and asked, "Have you written the question they were talking about, the sixteenth question?"

Yunyan took out the roll and nodded, "I wrote it, one roll or two rolls."

The man was shocked: "Of course it's the first volume. The second volume is too difficult. I couldn't bear it until half past one, so I went to sleep."

After speaking, he asked, "Did you write it?"

"...I'm done."

Chapter 52

Yunyan took out her own paper and handed it to the next table.

It was the two sets of test papers that the teacher mentioned yesterday, Volume 1 and Volume 2.

The teacher said: "The first volume tests simple knowledge points, and everyone has to finish it. The second volume is a test of thinking. You can pick yourselves and watch the simple ones. If you can't do it, leave it empty. Don't stay up too late, or your body will be overwhelmed."

Yun Yan felt that at this time, following the teacher's rhythm was absolutely no problem.

So she finished one volume yesterday, and there are fill-in-the-blank questions in front of the second volume.

There are two volumes and two major questions left, and I originally planned to leave it and wait for it to be done in the class today.

But at that time the whole dormitory was studying.

If Yunyan went to sleep directly, his conscience would be uneasy, so he also finished the second volume.

The boy looked at Yun Yan's answer sheet, his cheeks twitched quickly.

"Fuck, depend, depend! Is this the strength of No. 1 in the province? I've learned a lot."

His deskmate quickly moved up, and after reading it, he threw out two words with trembling lips.

"Fuck!"

"Is this the result of Xueba sleeping at half past eleven last night?"

"Stop talking, look at the questions. Thinking about how many questions I have not finished until half past one, it's really incomparable between people."

With that said, the two of them studied the answer to this question together.

It's not that they don't know it at all, it's just that there has been a problem with the process of taking the derivative, so the result is wrong.

Before Yun Yan came, they also discussed this topic with the boys behind.

Therefore, the boy who was talking to Zhuo Feilan saw that the two of them suddenly started to write quickly, and roared directly: "Damn, did you two come up with the answer?"

Don't you share it with your brothers?

Just a few minutes of effort.

There were quite a few people in the class, and everyone was discussing topics in twos and threes, and the class was a little noisy for a while.

There is a big difference in distance, and you have to rely on roaring to speak.

"Not yet, I'm looking at the standard answer."

"Standard answer, are you two kidding me? Our standard answer is only the answer, not the process."

Otherwise, everyone would not be able to solve it so hard.

But the two boys in the front row obviously don't have time to answer him now.

Because they are thinking about Yunyan's problem-solving ideas.

When Yunyan calculated this question, he did not seek guidance.

Just put the partial differential equation in the first step, and then use the remaining known conditions to derive the formula you want, and directly bring the equation of the first step into it.

This problem is solved.

"That's how it should be."

"We really jumped into the pit dug by the questioner."

"No, not only jumping in, but also digging deep with a shovel."

Because even if this question requires guidance, it is not the first formula to be calculated.

That preservation is just a confusing condition. If you really want to waste time on calculations, you will suffer a big loss.

"I really didn't expect to abandon this equation directly and use the rest of the known conditions to calculate."

"Wait a minute, why does this step have to be divided by the original unknown?"

"Let me see..."

Seeing that the boys at the back were ignoring them, they walked over with the papers.

After looking at it for a few minutes, he said, "This answer is really six, who wrote it?"

This classmate just told Zhuo Feilan about the mistake of seeking guidance, and he didn't hear what the people in the front row were saying.

The two boys who first took the Yunyan test paper pointed to her quietly.

"The paper of the boss."

So, the boy also joined the large army with twitching lips and cheeks.
