In the office, Yu Huan and Lin Xia moved two small stools to change the papers at Cheng Xin's desk.

Because I read Chen Ke's paper in class, Yu Huan changed it quite quickly, and the questions she learned in the first and second years of high school were quickly corrected, that is, she had blind spots in the knowledge points of the third year of high school, and there were still a few questions empty.

As for Lin Xia, she was about to bite the cap in her hand.

Look at the east for a while, look at the west for a while, especially looking at Yu Huan, who writes smoothly, with a head full of question marks.

Cheng Xin glanced at Yu Huan several times, and originally wanted to ask what she was doing with Gu Jing just now, for fear that if she didn't study herself, she would bring the sixth class of students to ruin.

After all, it was cultivated by Lao Chen with the top prize in the college entrance examination, if something goes wrong, he must not strangle him?

But he didn't ask the words, but he found out unexpectedly that Yu Huan changed the question very quickly.

What to do with writing so fast?

To ensure the accuracy rate, why is this little girl so impetuous?

You still have to calm down when you do the question, this is a wrong one, it is better to copy the answer twice.

He was about to open his mouth to say a few words to her, and if he didn't know, he could ask, but he found that this little girl did the question.... It seems to be all right.

The steps are clear, the idea of solving the problem is quite clear, and the answer seems to be right.

And this word looks a lot better than before.

Cheng Xin felt a little surprised, but after thinking about it, in the past two days, except for this time when she was late, this little girl seemed to be quite peaceful.

I heard several teachers say that I don't play games in class, I don't sleep, and I read math books quietly.

He didn't believe it at first.

But now, it seems to be a little believed.

Cheng Xin took Yu Huan's roll and looked at it twice,

"Do you know all these questions?"

Yu Huan nodded,

"The one who has changed it will be."

The remaining few are blind spots, and I feel a little at a loss.

Cheng Xin took the pen in her hand,

"Which one won't, I'll tell you."

"This."

Yu Huan pointed to the big question on the third page,

"This."

Cheng Xin glanced at Lin Xia,

"Listen to it."

So Lin Xia also came over, although she didn't want to hear much about the small stove opened by the head teacher, she couldn't help it.

After a set of volumes, Cheng Xin found that Yu Huan's thinking was quite fast, and she could understand it at one point, and she immediately wrote down a few knowledge points that she didn't know.

This speed of learning is not at all like a scumbag who is at the bottom of his grade.

"Have you ever made this set of rolls before?"

Cheng Xin couldn't help but ask, because Yu Huan learned too fast, so fast that it was surprising.

Yu Huan glanced at Cheng Xin and asked,

"Didn't this set of papers just come out in the morning?"

Moreover, it was his own question.

Cheng Xin: "......."

Yes, the questions in this set of papers are his own, and they are not past years.

He coughed twice, and suddenly felt that the question he had just asked was a little retarded, how could she have done the question he had just come up with?

So Cheng Xin looked serious,

"Yu Huan, you did a good job in this paper, which shows that you are still very smart, and if you put your mind on studying as soon as possible, you will definitely be able to achieve good results."

Yu Huan nodded, his pure eyes full of seriousness.

Cheng Xin looked at it and felt that Yu Huan's attitude was very good, so he spoke again,

"If there is anything that won't happen in the future, come to the office and ask me."

"Yu Huan can go back, Lin Xia stays and continues to change."

Hearing Cheng Xin's words, Lin Xia almost wailed.

Yu Huan nodded at Cheng Xin,

"Then teacher, I'll go first."

"Go back and study hard."

Cheng Xin added, Yu Huan went out with his own roll, and winked at Lin Xia before leaving, as if he was silently saying, come on!

But Lin Xia couldn't mention the word "come on" at all, and even wanted to tear up the test paper in front of him.
