After Liu Yichen completed the operation, he put the laptop into his bag. This laptop should not be known to anyone now, otherwise it would still be troublesome.

"Sister~~" Liu Yichen came out of the room and saw Liu Tingting doing her homework there, but she was dawdling. As for Lao Liu, she no longer knew where she was.

"I told you, don't call me sister, you want to die!" Liu Tingting looked over with a murderous look in her eyes. Even though she was thin and looked like a lady, she was actually very stubborn. Otherwise, she would not have done anything.

I would confront Lao Liu from time to time.

Liu Yichen said: "Tomorrow morning, I'll treat you to steak, will you come or not?"

"Really? You didn't lie to me?" Liu Tingting looked at Liu Yichen suspiciously, not believing it. When did this bratty brother become so generous?

"Really, it's more real than real gold." Liu Yichen said, "Forget it if you don't go, I'll go alone."

"No, no, I have to go!" Liu Tingting said quickly. She has never eaten steak in her entire life.

"Remember, this is a secret between the two of us. Don't tell Mr. Liu and Mr. Deng!" Liu Yichen lowered his voice.

Liu Tingting didn't know what it meant, so she naturally had no objection.

Seeing Liu Tingting suffering from a math test paper, Liu Yichen couldn't help but point out. To be honest, he didn't think Liu Tingting was stupid, but he just didn't know why. Liu Tingting's math was just average.

It can no longer even be said to be average, but it is seriously lagging behind.

And it seemed that he didn't read the notebook he gave him before. Otherwise, Liu Yichen felt that it would be no problem to get 60 points for a 100-point math question.

When Liu Tingting understood it, Liu Yichen almost collapsed. He actually had to explain a question very carefully from beginning to end twice before Liu Tingting could understand it.

Liu Yichen secretly murmured in his heart that his sister's partiality was really serious, and if she continued like this, there would really be no cure.

In the past, everyone would say that boys tend to be partial to subjects, and their partiality to subjects is serious. In fact, they often ignore that girls can also be partial to subjects, and their partiality is no worse than boys.

Think about last year, Liu Tingting chose liberal arts to avoid mathematics, which she hated and hated so much. She thought that liberal arts meant learning Chinese, English, history, geography, and politics. But she didn’t expect that after going to liberal arts, she still had mathematics, and mathematics was still there.

The score was 150, which almost made her collapse. At the end of the first day of liberal arts class, Liu Tingting went home crying to her mother.

well!

In order to save his sister, Liu Yichen could only endure the impatience in his heart. He picked up Mathematics Compulsory Course 3 and explained it from beginning to end. If Liu Yichen didn't understand, he would stop and explain in detail, especially statistics and probability. Liu Yichen even took out the math from his home

Practical explanations of rice, bowls, and dice. In the first semester of high school, you have to teach compulsory mathematics course 3. Some schools even teach compulsory mathematics course 4 faster. However, in the second semester of high school, elective courses are taught, as much as possible.

It is best to end the teaching of high school mathematics before the end of the second semester of the second semester of high school, and wait until the beginning of the third year of high school to officially start the first round of mathematics review.

It was rare for Liu Yichen to come back. He taught high school mathematics compulsory course 3 from beginning to end until 12 o'clock in the evening. Next day, he will combine the after-class exercises to consolidate and deepen his understanding.

Normally, if you are able to master the after-school exercises, your math scores will probably be at an average level.

"It seems that during the winter vacation, I have to make up for my sister's lessons. Otherwise, I won't be able to keep up when I reach the third year of high school!" Liu Yichen muttered to himself.

The third year of high school is an important node. In the third year of high school, many boys' advantages begin to come into play, because boys have better physical fitness. Maybe the first and second years of high school are not serious enough, but in the third year of high school, there is a sense of urgency.

Students will study more seriously, and their grades will naturally improve significantly. On the contrary, girls' weaknesses begin to be highlighted. Faced with endless test papers and review rounds after rounds, the more they study, the more confused they become.

For girls who don’t have a good foundation in math, which requires good thinking and logic, it will be difficult for them to keep up with and solidify their foundation even if they review for three rounds in the third year of high school. They will only get worse as they take the test. A 150-point paper will score 60 points.

, 70 points abound, and even 40 or 50 points are normal and not something to be anxious about.

Liu Yichen felt that the winter vacation and summer vacation were the last chance to save her sister. If she didn't save her, she would really be hopeless.

Liu Tingting's grades in other subjects are actually pretty good, but math is a serious hindrance. Even if she chooses liberal arts in separate classes for arts and sciences, she can't escape the demon of math and is suppressed. A 150-point math award, I dare to give you 30 points.

40 points. You must know that this is a test paper for No. 2 Middle School, not No. 1 Middle School. The test paper for No. 2 Middle School is much simpler than the test paper for No. 1 Middle School.

This will be fully reflected in the unified examination for the third year of high school. At this time, the examination papers for the entire Qingcheng will be unified, and even the examination papers for the entire Western Fujian high school will be the same paper, and it will be clear what level you are at.

Often the top performers in the second middle school can only be ranked in the middle or lower reaches of the first middle school.

As for Qingcheng No. 1 Middle School, the number one school in each year is often not ranked among the top ten in the city, ranking between 20 and 50.

Liu Yichen returned to his room and did not go to sleep immediately. Instead, he wrote down a plan. He named this plan - the Plan to Save Sister!

It is unrealistic to improve her scores in all subjects in all aspects. The fastest and best way to improve her scores is to help her improve her math scores. As long as her math test score can be raised to 130 points, it is equivalent to Liu Tingting's improvement of 90 points.

~100 points, which is impressive enough.

If it reaches this point, Liu Tingting can reach the upper level in No. 2 Middle School, and should be able to pass one in the college entrance examination.

Liu Yichen broke down the goals above. For example, Liu Tingting took compulsory course 1, compulsory 2, and compulsory 3 in high school mathematics during the winter vacation. During the summer vacation, she took up compulsory course 4 and other liberal arts mathematics elective parts. This should not be a big problem.

well!

Sighing, Liu Yichen felt that it was really too difficult for him. Not only did he have to study hard to become a top student, but he also had to save his sister, which was very tiring!

You can't just ignore the problem, she's your own sister.

I have never heard of the demon who supports his younger brother, but never the demon who supports his sister. Now he has no hesitation in embarking on the path of the demon who supports his sister.

Liu Yichen laughed at himself. If he had waited more than ten years to post a question on Zhihu: "What would you do if you had a boyfriend who was a supporter of your sister?", he would probably be criticized and criticized constantly.
