After taking the advice, I became a top student.

[Host detected copying 5 pages of math textbook, task completion 0.35%, nutrient +20]

As soon as Chen Mo sat down next to Shen Qingyi, he saw the notification in front of him.

He suddenly moved the desk up, not because Li Ze persuaded him, but simply because the next class was math.

With a thought, the panel appeared.

[Suggestion: Focus intensely on math. Reward: 100-10000 nutrient points depending on completion rate.]

Nutrients are captivating.

Although he had already decided to complete the suggestion of copying the book first, the reward for this suggestion also tempted Chen Mo. Moreover, it was only one less math class to copy, which would not have a big impact. At the same time, copying the math textbook was also a way for him to work hard on math, and there might even be a bonus. It was a win-win situation.

"?"

"So what exactly happened? Did you make up again?"

Little did he know that his action had left the rest of the class stunned.

The happier Zhou Hao was in chemistry class, the more miserable he was at this moment.

Shen Qingyi was also taken aback, somewhat unable to fathom Chen Mo's thoughts, but she was still gratified to see that Chen Mo had come to his senses.

When the bell rang, Hu Xin walked into the classroom with his textbook. He was used to the student in the aisle and didn't delay, starting the lesson immediately.

Today we'll still be talking about functions, specifically how to find their analytical expressions.

After explaining the method, Hu Xin asked an example question as usual. Chen Mo raised his hand immediately, but this time, Shen Qingyi and Zhou Hao were also among those who raised their hands.

Zhou Hao glared at Chen Mo with eyes blazing with anger. Since Shen Qingyi liked students who answered questions in class, he would actively answer questions in class. It wasn't like he didn't know how.

Hu Xin looked with satisfaction at the classroom that was starting to get lively.

This prosperous era is just as he wished!

Instead of calling on Chen Mo, this time he called on Zhou Hao to answer the question.

"This problem can be solved using substitution."

Zhou Hao raised his head slightly and said confidently, "But this problem is very troublesome to solve using the substitution method. By the time we solve it, get out of class will be over."

"When we encounter such troublesome situations, we need to observe the relationship between the independent variable and the subsequent equation, which is actually very similar to the constructor function."

"For example, in this problem, f(x-1/x)=x^2+1/x^2, these two expressions are clearly related. If we can't see the relationship at a glance when we want to find the analytical expression of f(x), we can try taking the perfect square root of the first expression first."

「就会发现，(x-1/x)^2=x^2+1/x^2-2，这开出来的就是后面的等式，所以我们带入进去，就能得到f(x-1/x)=(x-1/x)^2+2，这表达式不就出来了吗，f(x)=x^2+2。」

After Zhou Hao finished speaking, he raised his head even higher. This question was not too difficult, but it was not simple either. In addition, his unique solution was a perfect demonstration of his ability. Answering such a question made him quite proud.

"Not bad!"

Hu Xin nodded, "Zhou Hao is right. This problem cannot be solved by rigidly using the substitution method, otherwise it will be very troublesome to calculate. So when you encounter this type of problem in the future, you can first observe the relationship between the two expressions, which will make the solution more efficient."

"As expected of Zhou Hao, he's awesome!"

"I was wondering why this problem was so complicated; it turns out I hadn't found the right method. But how did the expert figure out at a glance that it could be solved by squaring?"

"Stop talking, just practice more. If you can spot it at a glance, you're a top student."

The students chirped softly, and Zhou Hao's image in their hearts grew even more impressive once again.

This made Zhou Hao very satisfied. He experienced the joy of answering questions for the first time, and he decided to raise his hand to answer questions more often in the future. It felt great!

"Okay, let's do a few more example problems next."

As he spoke, Hu Xin clicked the mouse again and displayed the next example problem: Given that the linear function f(x) satisfies f(f(x))=4x-3, then what is the value of f(1)?

"Can someone explain the thought process behind this problem?"

Hu Xin looked towards the classroom.

Chen Mo raised his hand without hesitation.

This time, Shen Qingyi and Zhou Hao did not follow.

Zhou Hao was speechless. Seriously, buddy, are you really hungry? Why are you raising your hand for every question?

What's the point of answering such a simple question?

Hu Xin was also somewhat surprised, but this question was indeed the kind that those who knew how to do it found easy, while those who didn't know how to do it wouldn't raise their hands. So, this time, only Chen Mo raised his hand again, and he had no other choice.

Chen Mo didn't pick and choose, and stood up seriously, saying, "Since it's a linear function, let's set f(x) = kx + b, and then substitute it into the original expression, we can get k^2x + kb + b = 4x - 3, so k^2 = 4, kb + b = -3. Solving a quadratic equation in two variables will give us the original expression."

[Suggestion complete. Actively raise your hand to answer questions in class. +100 points]

Seeing the notification light up in front of him, Chen Mo sat down with satisfaction.

The reward for this suggestion is fixed, but unfortunately it can only be completed once a day. Otherwise, Chen Mo could get a lot of nutrients every day by just doing this.

Soon, math class ended, and Chen Mo moved his seat back to its original location.

[Suggestion complete. Pay attention in class. +30 points]

Seeing the notification light up in front of him, Chen Mo remembered that Li Ze had given him a suggestion earlier. What an unexpected surprise! He really is a good brother!

"I'll treat you to stir-fried beef for lunch!"

Chen Mo happily told Li Ze that an extra 30 nutrients every day would add up to a considerable amount over time, and he would definitely have to treat him to a stir-fried beef dish.

"what?"

Li Ze didn't know why Chen Mo suddenly wanted to invite him to dinner. Before he could say anything, Chen Mo had already taken his math textbook to Shen Qingyi's side and started asking questions.

This time, he didn't ask about the content of the lesson, which indeed didn't have many difficult points. He asked about the problems encountered when copying from the textbook.

Although Shen Qingyi didn't know what Chen Mo was up to, she still answered all his questions and explained the problem to him in a serious manner.

[Daily suggestion complete. Ask the class beauty a question every day, +22 points]

The questions asked today were of higher quality, and I learned a lot more from them.

The next class was a Chinese language class, so Chen Mo naturally didn't move the book back, but continued copying from the book at his seat.

The students are now completely baffled as to what Chen Mo is doing. They just think this guy is too free, going wherever he wants.

11 p.m.

Lying in bed, I brought up the control panel.

[Host: Chen Mo]

[Logical Thinking: D (38/100) - Average Level]

[Memory Ability: D (44/100) - Average Level]

[Focus: D+ (93/100) - Slightly better than average]

Comprehension: D (35/100) - Average level

[Willpower: B+ (68/100) - Only strength]

[Special Effect: Front Row Aura]

[Nutrients: 7]

After a day of hard work, he has raised his focus to 93, which, with the added advantage of being in the front row, would be enough to reach level C.

Besides completing other suggestions, Chen Mo gained over 300 nutrients today just by copying books. At this rate, he will soon be able to raise all his attributes to C-level.

Chen Mo was somewhat expectant.

Before going to bed, he took out his phone again and began collecting new suggestions from netizens.

If you're not very bright, just ask more questions! I suggest you wait for your teacher after every class and ask them questions until they get tired of you.

Find a top student in your class, and do exactly what they do, imitating them until you surpass them.

Did Lu Xun know that he carved the character "早" (early) on his desk, and he was never late again? I suggest you carve "I want to go to Tsinghua University" on your desk to motivate yourself.
