Take a break and finish eating the buns.

While eating, he thought: "I definitely can't give these things directly to my wife after I take them back."

"Just give it to her directly. She won't be able to read it."

"I still need to reorganize and categorize it myself, so that it will be easier for her to learn."

"Besides, if I just send her the electronic version I bought, how will she know how hard I've worked?"

"To do practical work without taking credit is something only fools would do."

"I'm not stupid!"

"Not only should we say it, but we should also exaggerate it."

"I went home and told my wife that I had stayed up late last night to do this, so that she would feel bad."

Thinking of this, Fuhei Chen started to work.

Give the existing data a deep processing.

Start with mathematics and reorganize and classify the knowledge points of the three years of junior high school.

First, create a new Excel table and enter the title in each cell of the first row:

"Major category", "grade", "chapters", "knowledge points", "key knowledge points", and "corresponding high school knowledge points".

Today, let’s sort out the key test points first.

As for the corresponding high school knowledge points, Lin Yuchen plans to let Li Changyan sort them out by herself after she finishes the junior high school knowledge, so as to exercise her knowledge association and information retrieval abilities.

Open the folder that summarizes the three years of junior high school mathematics knowledge that I bought, and go over the knowledge points first.

Then, we made some great changes and categorized the knowledge points.

First of all, in the “major categories”, Lin Yuchen divided the three years of knowledge into six categories: “numbers”, “formulas”, “equations”, “graphs”, “functions”, and “data”.

The knowledge points that fall into the general category of "numbers" include: "Rational Numbers" in the first chapter of the first semester of the first year of junior high school and "Real Numbers" in the thirteenth chapter of the first semester of the second year of junior high school.

The major category of "expressions" includes: Chapter 2 "Addition and Subtraction of Polynomials" in the first volume of seventh grade, Chapter 9 "Inequalities and Groups of Inequalities" in the second volume of seventh grade, Chapter 15 "Multiplication, Division and Factorization of Polynomials" in the first volume of eighth grade, Chapter 16 "Fractions" in the second volume of eighth grade, and Chapter 21 "Quadratic Roots" in the first volume of ninth grade.

The major category of "equations" includes: "Linear equations of one variable" in the first volume of seventh grade, "System of linear equations of two variables" in the second volume of seventh grade, and "Quadratic equations of one variable" in the first volume of ninth grade.

The "Graphics" category contains many important knowledge points. In the senior high school exams, there is at least one 14-point question that is a graphics question.

So it needs to be taken seriously.

It mainly includes: "Introduction to the understanding of shapes", "Intersecting lines and parallel lines", and "Triangle" in grade 7; "Congruent triangles", "Pythagorean theorem", and "Quadrilateral" in grade 8; and "Rotation", "Circle", "Similarity", and "Projection and View" in grade 9.

Besides graphs, function is another knowledge point that needs to be paid attention to, and it accounts for a large proportion in the college entrance examination.

If you don't learn functions well in junior high school, it will be impossible to master functions in high school.

Big math problems tend to be one thing after another. Without a solid foundation, how can you solve comprehensive problems?

The knowledge points of "function" in the entire junior high school include: "linear function" and "inverse proportional function" in grade eight; "quadratic function" and "acute angle trigonometric function" in grade nine.

In addition, Lin Yuchen also classified the two knowledge points of "Plane Rectangular Coordinate System" in the seventh grade and "Axial Symmetry" in the eighth grade into the category of "function".

Finally, there is the "data" category, which includes "data collection, organization and description" in grade 7, "data analysis" in grade 8, and "probability" in grade 9. You can go through this type of knowledge briefly, but you should also know that it is also related to the number series in high school.

After categorizing, extract the key test points of the corresponding knowledge points and put them in the "key knowledge points" column.

It took about two hours to finish everything.

Lin Yuchen sorted out the six thick books from the three years of junior high school into two full pages of A4 paper.

No wonder teachers always say that at the end of a book, it’s just a page.

After leaving the Internet cafe, I went to the photo studio next door to print out the two pages of paper and put them in my schoolbag.

Ride your bike to school.

The first class in the afternoon was chemistry. The chemistry teacher of Class 10 was a female teacher in her thirties, single, serious and responsible.

(Refer to the image of Miejue Nun Tai)

She must not be late for her class.

Thinking of this, Lin Yuchen pedaled hard on his bicycle, shortening the journey of ten minutes to five minutes.

I finally managed to sit down one minute before class started.

Li Changyan, Liu Haoran and Lin Ni were all frightened by Lin Yuchen.

"Achen, where have you been? Why are you so red-faced and sweaty?" Liu Haoran was the first to ask the question.

Lin Yuchen took out his water cup: "Haozi, please help me get some warm water first."

Liu Haoran took the cup and ran towards the water dispenser.

The water dispenser was installed at the door of the teacher's office. As soon as the water was connected, the chemistry teacher had already picked up the test papers and experimental tools and was ready to walk out of the office.

Liu Haoran was a little afraid of her, so he turned the water on to the maximum, took two-thirds of the water, and then went back to the classroom to report.

In the classroom, Li Changyan took out two tissues and handed them to Lin Yuchen while talking.

"Hey, boss, why don't you sleep in the middle of the day and go run a marathon?"

"You still have a conscience and know to hand me the tissue." Lin Yuchen took the tissue from Li Changyan, feeling resentful in his heart.

Lin Ni didn't say anything, but turned to look at Lin Yuchen, obviously curious about where he went at noon.

Lin Yuchen put away his schoolbag, took out his chemistry textbook and test paper, and was about to speak when Liu Haoran came back with some water.

Just as I took the cup of water and was about to explain, the bell rang and the chemistry teacher was already standing at the classroom door.

There was no choice but for everyone to take their seats and prepare for class.

"Attend class."

"stand up."

"sit down."

The chemistry teacher stood on the podium, put down the experimental tools and test papers, and scanned the entire classroom. When his eyes passed by Lin Yuchen, he paused.

Because Lin Yuchen scored 95 points in chemistry in this monthly exam, ranking first in the class and tied for second in the grade.

So Nun Miejue...ah no, the chemistry teacher had an impression of him, and a good impression of him.

He glanced at him and said nothing. He asked everyone to take out the monthly chemistry test papers and continued to explain the test papers.

"Let's continue with the questions we didn't finish last class. Everyone, please look at question 7 of the multiple-choice test."

"The question asks: What happens when magnesium burns in the air? Which of the following options is correct?"

"A: emits dazzling white light and gives off heat;"

"B: emits a bright blue-violet flame and gives off heat;"

"C: a black solid is produced;"

"D: White powder is generated."

"This question tests junior high school knowledge. Please ask a student to answer it. If any student wants to come up, please raise your hand."

The classroom was silent.
