A genius? I just love studying.

Chapter 2 Class Test
“Finally reached 60%!”

A trace of joy appeared in Chen Hui's heart. He knew how difficult it was to come this far, and only he knew the bitterness.

With a thought, a data panel appeared before his eyes.

[Host: Chen Hui
Chinese Level 1 (53%)

Mathematics Level 1 (60%)

English Level 1 (37%)

Physics Level 1 (41%)

Chemistry Level 1 (23%)

Biology Level 1 (26%)

history……】

Without considering his proficiency in history, geography and politics, Chen Hui had already decided to study science. He had selectively given up these three courses as he had limited time.

Maybe it is true that when God closes a door for you, he will open a window for you.

Although Chen Hui was a slow learner, he had this data panel in his mind since he was a child. After countless attempts and verifications, he knew that other students did not have this data panel.

As long as he focused on studying a course, whether it was doing exercises or reading books, the corresponding proficiency on the data panel would slowly increase, of course, extremely slowly!

Otherwise, he wouldn't have just barely passed the Chinese and math subjects until now.

As proficiency increased, it became easier to improve it. So Chen Hui gave up other courses for the past six months and focused on improving mathematics. He wanted to know what would happen if he could improve his proficiency to 100%.

After so many years of research, he now understands that this so-called Level 1 is roughly the level of a normal student. For example, his Chinese proficiency is 53%, so his scores in recent Chinese exams have always fluctuated around 80 points (out of 150).

I don’t know if I can get full marks if I raise my proficiency to 100%?
Chen Hui couldn't help but look forward to a bright future.

He didn't know if there would be levels 2 and 3 after reaching 100% proficiency, but even if it was 100% level 1, it would be of great benefit to him.

I just don’t know if the time is enough.

There are only two and a half years left until the college entrance examination, and I don’t know how far I will have come by then.

I should be able to get into university, right?
No, this is not enough!

Thinking of the situation at home, Chen Hui quickly calmed down and focused his attention on the exercise book in front of him again.

If they could only get into university, their family might not have the money to pay the tuition. Even if they sold everything they had to pay, he couldn't bear to suck the blood of his uncle and aunt.

"Hui, it's OK, 90 points!"

Just as he was about to look at the next question, his deskmate's exaggerated voice came over. The next moment, a test paper appeared in front of Chen Hui, with the two numbers 90 written on it in red pen shining brightly.

Chen Hui was a little surprised. When he did this set of questions yesterday, his math proficiency was only 59%. It seemed that he performed beyond his capacity.

"Why don't we treat you to a meal to celebrate?"

My deskmate Li Hai kept chattering.

Chen Hui, in a good mood, took the test paper with a smile and turned his head to look at his deskmate, "There's plenty of porridge in the cafeteria!"

The porridge in the cafeteria is free.

"whispering sound!"

Li Hai scoffed, "It has to be the stir-fried dishes from the second floor."

Chen Hui ignored him and continued looking at the exercise book. Everyone knew his family situation, and Li Hai was just talking nonsense without any ill intentions.

[You pass any subject exam, gain +1 free attribute point]

However, the moment he turned his head, another line of text appeared before his eyes.

Chen Hui was a little stunned.

Free attribute points?

He had lived with data panels for 16 years, and this was the first time he had seen this thing.

Soon he became excited again. Change was definitely a good thing for him who was almost at the bottom of the valley.

A thought in my mind,
[Host: Chen Hui
Insight Level 0: (0.9/1)+
Judgment Level 0: (0.8/1) +
Creativity Level 0: (0.5/1) +
Memory level 0: (0.6/1) +]

A new data panel appeared before my eyes!
Seeing this, Chen Hui suddenly understood why he always felt slower than other students, learned slower, and remembered slower.

If level 1 is the level of a normal student, then does level 0 mean that his four abilities are far below those of an average student?
He even suspected that other students were born with initial attributes, while he started with 0 attributes.

God knows how he got through these 16 years.

But he has never been the type to complain, and he quickly turned his attention back to the panel in front of him.

This new panel appears because of the free attribute points. Combined with the + signs behind these four attributes, can the free attribute points be used to improve these four abilities?
Chen Hui focused his attention on the plus sign after insight without hesitation.

According to his years of experience, it is more beneficial to improve an attribute to the extreme. The panel seemed to shake like a wave, and the content had changed.
[Host: Chen Hui
Insight Level 1: (1.9/2)

Judgment Level 0: (0.8/1)

Creativity Level 0: (0.5/1)

Memory Level 0: (0.6/1)

If Level 1 is the level of normal students, and Level 1 100% is full ability, then what about Level 2?

Above full marks?

Looking at the 1.9 in the insight column, it is only 0.1 away from 2.

"So, my insight now exceeds that of most of my classmates, almost reaching the limit of a normal student?"

Chen Hui felt that his brain seemed to be working much faster, and he subconsciously turned his head to look at the exercise book.

"Okay, we have an hour, so do as much as you can."

The young and middle-aged man on the podium knocked on the desk and looked down at the entire classroom from above.

Chen Hui only then realized that there was an extra test paper in front of him. It was handed to him by Li Hai. The other students had already started doing the questions.

This test paper is a bit strange. It is not like the usual exam format. It only has 8 fill-in-the-blank questions and 3 essay questions. It does not look like a test paper, but like questions randomly given by the teacher.

I didn’t think much about it. Since it was a question, I just did it.

The improvement of proficiency is also traceable. The faster you improve by solving more difficult questions, of course, it will take more time to solve difficult questions.

1. The sum of all elements of the set A = {n|n^3<2025<3^n, n∈Z} is ____
Hey, Lao An’s set of questions is not difficult.

Chen Hui found that he understood the meaning of the question the first time he read it.

12^3=1728, 13^3=2197, so n^3<2025, then n≤12, 3^6=729, 3^7=2187, so 2025<3^n, then n≥7, so the possible values ​​of n are 7, 8, 9, 10, 11, 12, and their sum is 57!

Write the answer to the first question easily.

2. Let the function f(x) = (x^2+x+16)/x (2≤x≤a), a>2, if the range of f(x) is [9, 11], then the range of a is____
The second question examines a function. This is obviously a check mark function shifted upward by one unit, a graph is drawn, and the minimum value is found. Based on the range of values, the value of the boundary point x can be easily obtained, and naturally the value range of a can be easily calculated as 4≤a≤8.

The third question is about probability, which is also not difficult. The fourth question is about complex number operations. The fifth question is about geometry. As long as you draw a figure and do some "little reasoning", you can still easily calculate that the area of ​​the tetrahedron P-ABCD is equal to the square root of two-sixths.

"Easy to take!"

Li Hai, who was sitting next to Chen Hui, was full of confidence. After writing down the answer, he looked at the sixth question.

6. Given that the graph of the function y = f(x) is symmetrical about the center of point (1, 1) and about the axis of line x + y = 0, if x∈ (0, 1), f(x) = log2(x+1), then the value of f(log2(10)) is ____
After reading the question, Li Hai was silent for two seconds, then began to draw a picture. After fiddling with it for a while, Li Hai looked directly at the next question.

7. In a rectangular coordinate system, the ellipse Ω: x^2/4+y^2=1, P is a moving point on Ω, A and B are two fixed points, where B's coordinates are (0, 3). If the minimum area of ​​△PAB is 1 and the maximum area is 5, then the length of line segment AB is ____
This time, after reading the question, Li Hai saved the trouble of fiddling with the draft paper and went straight to the next question.

Question 8 is a question about calculating probability.

Li Hai gave up before even finishing the question. This was the realization he gained from countless failures.

When people are pushed to the limit, they can do anything, but they just can't solve math problems, and there's nothing you can do about it.

Li Hai has a clear understanding of his math ability. He usually scores around 100 points, and he has tried his best.

Leave professional matters to professionals.

He subconsciously raised his head and looked to the front right. There was the seat of Liang Peixuan, the math genius in the class who had scored 137 in the entrance examination yesterday.

However, before he could see Liang Peixuan's test paper clearly, Li Hai suddenly turned around and looked at his deskmate.

"???"

What dirt did he see?

Chen Hui was actually already answering the questions!

What’s even more outrageous is that the answers to the first eight fill-in-the-blank questions are already written in the blanks!
isn't it?
really!
This guy must have just written the answer randomly!
Li Hai denied the three consecutive times, because he was also prepared to write some data on the questions he didn't know, such as the square root of two, the square root of three thirds, etc.

57, 4≤a≤8, three-quarters, square root of 3*i, square root of sixth...

Subconsciously checking the answers to the first five questions, Li Hai took a breath of cold air. Chen Hui's answers were actually the same as his!
Although he is not a math genius, he is still confident about the answers to the first five questions and he thinks they should all be correct.

Chen Hui's answers to the first five questions were the same as his, so...

Seventeen fifths, square root of seven, 1026.

Li Hai looked at Chen Hui's answers to questions 6, 7 and 8 and fell into deep thought.

Then quickly, he looked at his test paper again and began to write and draw on the draft paper.

Since Chen Hui can do it, there is no reason why he can't do it.
