Maybe in the eyes of other students, Xi Zirong may like her, which is big news, but for Xu Su himself, he doesn't think there is anything unusual.

Xu Su walked back to his seat expressionlessly, did not sit down, but turned out the math paper handed out in the morning in the hole in the table, took the pen again, and walked to Huang Feng to make the paper.

It wasn't until Huang Feng came to the same table that Xu Su returned to his position.

There was still an hour left before the afternoon class, but the classroom was almost full.

Xu Su was finishing the last big question of the first paper, and Chen Huiyu next to him suddenly handed over a scroll.

"Susu, help me look at this question, I can't do it."

Xu Su took it, and she hadn't started doing this test paper yet.

After carefully reading the topic, Xu Su frowned and hesitated to take out the scratch paper and make a tentative calculation.

After a while...

A little more later...

She put down her pen in frustration and looked at Chen Huiyu who was expecting on the side, "I'm not sure what to do, wait for me to think about it." ”

This is not an exam paper, it's just a test paper sent down for everyone to do publicly, can Mr. Wu use it so ruthlessly, and give such a difficult question!

Thinking that the teacher said that the test points of the midterm exam were all focused on these four papers, it was even more difficult for people to eat all these questions.

"Which way?" Xi Zirong's inquiry voice came from behind him.

Xu Su's body stiffened and he didn't look back.

Chen Huiyu excitedly handed over the paper, "The last proof question, learn God, can you write down the proof steps for us to see." ”

The person behind didn't speak, so he should have replied with a nod.

The classroom was quiet, Xu Su heard the sound of the tip of the pen constantly touching the paper, and not long after, a densely written scratch paper was handed over.

"Three methods, steps are written out."

Xu Su rejected the proof method shared by Chen Huiyu, she didn't feel that as a representative of the math class, there was really any teacher who had taught and couldn't do the math problems.

It's just that the reaction wasn't as quick as he was for a while.

The mid-term exam will be held in a week, and the already strong learning atmosphere in the class will be even more tense.

The teachers no longer had a quiz at every turn, as if they had made an appointment with Teacher Wu, and the teachers of each major subject handed out a few papers for the students to do privately.

When the class is officially held, it is still at their pace, the review that should be reviewed, and the new lesson that should be taught.

In the words of the Chinese teacher: "The knowledge of the half semester has been taught to you, and this exam is to test how much you have learned, all depending on your own strength, you are all big children, and there is no reason for the teacher to chase after you." ”

So in the past few days, students have almost no leisure time, and they are all doing papers in their morning and evening self-study and lunch break.

If you don't understand, ask the representatives of each subject first, and if the class representatives still don't understand, then you can only ask Xi Zirong.

After all, it is more convenient than other classes to have a god of learning.

So far, there are no exam questions that Xi Zirong can't do.

Other students could ask questions generously, but Xu Su, after feeling the change in the attitude of some students in the class, some didn't want to take the initiative to communicate with Xi Zirong.

Xu Su took cold medicine for three days in a row, and his symptoms finally improved.

At the evening self-study, Xu Sufen finished the last Chinese test paper and exhaled softly.

The papers sent by the teachers have been done, and at her level, the solutions to the two major problems in mathematics are still uncertain, and there are also major problems in physics and chemistry without a clue.

The language is okay, her foundation is there, and after the composition is completed, she only needs to check whether there are any mistakes.

English is the least to worry about, she passed the sixth level in her previous life, and her high school English is still difficult for her.

Xu Su put away the Chinese test paper in his hand, took out the math paper again, found the problem that he had not overcome before, and began to think.

Xi Zirong looked at the girl in front of her who hadn't moved for half an hour, hesitated for a while, took out four rolls from the hole in the table, rolled them into a ball, and poked her back.

It's almost December, the weather is very cold, Xu Su goes out early and returns late to wear a lot, and wears three layers inside the school uniform jacket.

The innermost is a close-fitting cotton sweater, and then she wears a warm clothes, plus a turtleneck sweater that Grandma Xu knitted for her last year, the color is very beautiful, hand-woven, warm and thick, Xu Su cherishes it very much.

Through several layers of thick clothes, the mat allowed to poke the test paper for the third time, and Xu Su felt it.

She turned her head and didn't say anything, just a questioning look in her eyes.

Xi Zirong saw that she was finally willing to look at herself after so many days, handed over the test paper in her hand, and whispered, "Do you want to take it for reference?" ”

Xu Su glanced down, it was the math paper she needed.

After hesitating for a few seconds, he reached out and took it.

The teachers have said that if they don't know what to do, they can ask the students who will help each other to answer.

"My handwriting is a bit sloppy, if you don't understand something, just ask me."

Xu Su glanced up at the boy and nodded, "Thank you." ”

When I opened it, I saw that the mat was really modest.

The handwriting on the test paper is very neat, enough to be used as a model to watch, Xu Su skipped the front and went straight to the question that stumped him.

I found that it was densely written with detailed answers.

After only looking at the beginning, Xu Su grasped the vague train of thought, his mind moved, he didn't continue to look at the answer, and did it himself.

A lot of times, it's not that you can't do it, it's a blind spot, you need a little hint, and everything that follows falls into place.

It wasn't until the two unfinished math papers were solved that Xu Su began to use his own papers and mats to answer them.

Then, slowly, a smile appeared.

Xi Zirong wrote two solutions to each problem, and Xu Su's solution process happened to be one of them.

It's not comparable to Xueshen, but it's also made by your own strength.

Xu Su is very satisfied, she has found the joy of learning, solving difficult problems one by one, and she really has a sense of achievement.

He returned the scroll and thanked him again.

Xi Zirong seemed to have been prepared a long time ago, he handed over a few physics test papers in his hand, and asked very intimately: "Do you want chemistry papers?" ”

"......" Xu Su didn't care about the vague gaze around her this time, she nodded honestly: "Yes." ”

It can improve academic performance, why not?

turned around with the test paper given by the mat, and saw the small note on the table, which was passed by Chen Huiyu.

[Ahhhh The squad leader is chasing you, right? Yes, right? 】

Xu Su glanced at Chen Huiyu, she lowered her head to make a question, and her face was actually red with excitement.

Xu Su wrote a few words on the note and handed it back.

[Be good, do the question well. 】
