Lu Xingyin walked into the office, the students inside looked up at him neatly, the boy in the front seat asked softly, "Hey, why are you here for chemistry class?"

The representative of the chemistry class was distributing chapter exercises. Hou Hao also saw him, but uncharacteristically, he greeted him with a smile: "The place is small, so you can follow the corridor and listen to the class now. After all, you still have a little sense of crisis."

Thirty or so students from class 27 squeezed into the chemistry group, and they definitely couldn't fit in. Although the office of the chemistry group was very empty, there were still many students writing questions in the corridor.

Hou Hao sat at the desk and sorted out the knowledge points for them on the spot. It sounded no different from the content of ordinary classes. I don't know why it took so much trouble.

Qu Jiao and Chen Yuanyuan were sitting at the desk by the door. Seeing him coming, they squeezed to the side to make room for him: "Little deer come here! Sit with us—didn't you just say you couldn't come? "

As they asked, they secretly stuffed him with the remaining half-pack of crispy noodle snacks, and they didn't mean to get to the bottom of it.Lu Xingyin walked over and huddled in a chair with them, and saw a batch of numbered test papers on the desk in the clean classroom, looking at the name and class, it was a class.

There was a light yellow post-it note on it, with red writing on it: "The test papers will be distributed by the class representative, and the two students with full marks will take turns explaining, and the rest of the time will be self-study. If you have any questions, collect them and hand them to me. The teacher in the other class resigns, I will take the place, and I will wrong everyone first."

Looking at the date, it was a day ago, and the representatives of the first class did not come here to collect the test papers. I don't know if they forgot or didn't see it.

In this small class, Hou Hao talked about the knowledge points for 10 minutes, and wrote the unit test for them in the remaining 10 minutes.

Deer Walking Yin wrote quietly.

The rustle of the nib reminded him of what he was doing: studying.

Only learning is something that completely belongs to him and is under his control, and it is the only right track in everything he has experienced so far.

The restlessness subsided slowly, and Lu Xingyin began to force himself to write the unit test paper in front of him as quickly as possible, so that he didn't have to think about anything.

It was one of the little games he used to play when he first met the "Regents of Carleton University."In the summer vacation of the second year of junior high school, two teenagers who didn't even know how to use modeling tools lost the math competition, but became confidants in a certain sense.

The name of the "Chairman of Carleton University" is Zhou Jia, a young man with thick eyebrows and big eyes who is one year older than him.He competed with him to write the test papers. A timer was kept by his side. On the same test paper, both of them did not write or use scratch paper.

After reading the first half, turn the page to see the second half.After reading, everyone has 2 minutes to write down their answers.

The one that is right more naturally wins.

It was the most boring and blind mind game for a teenager at that age, but it gave Lu Xingyin an incredible way of growing up: he developed extremely powerful mental arithmetic ability and memory in this prank-like competition. Jia Jia is not as good as him in calculation, but his memory is stronger than him. Zhou Jia taught him how to use the "memory palace", how to correspond knowledge to everything in life one by one, and how to organize and divide knowledge points.

Chen Yuanyuan poked Lu Xingyin: "Primary school master, can you do this question? I wrote down every single word in my notes today, but I just couldn't find this knowledge point after searching for a long time. I didn't see it, or I copied it. gone?"

Qu Jiao looked over and said, "You mean the third-to-last question and the second-smallest question?"

Lu Xingyin was still reading the questions, while Chen Yuanyuan said on the other side, "That's right."

Qu Jiao: "It seems that he didn't talk about it, let's watch the elementary school bully first."

Lu Xingyin brought their notes and looked at it against this topic.

They are still in the organic part recently. Hou Hao taught a part of organic chemistry calculations in this class. Lu Xingyin could tell at a glance that this is a slightly more complicated calculation problem of organic laws.

But Hou Hao didn't mention a word about the routine solution to this question.Generally speaking, this part of the content is not summarized in textbooks, but it needs to be summarized by teachers and taught to students, and it may not be fully summarized in reference books.For example, starting from the calculation of oxygen consumption, for example, in C(X)H(Y), different ratios and masses of XY, publicity and induction, etc.

I can't finish talking about this in a while.

Lu Xingyin circled the topic and whispered, "Let's dance first, I'll tell you when I get back."

Chen Yuanyuan said: "Okay, alas, but the old monkey will take it up and change it, let us hand it in after we finish it."

"It's okay, I'll do it first, you just copy it as I say." Lu Xingyin continued in a low voice, "It's not convenient to talk about it here."

It's quiet around.

The students have solved this problem one after another, and they are all stumped.

One after another, people began to ask Hou Hao this question. Hou Hao stretched out his hand and made a quiet gesture: "One by one."
