Start as a top student and move towards the stars and the sea

Xu Yang, in fact, you fully understand the basic properties of functions, but you are not skilled enough in using them.

Yes, teacher, I can remember everything in the book, but I'm a little confused when it comes to doing the questions.

In this case, I will slightly change this question and see if you can do it.

Okay, let me give it a try.

The reason why Ning Chen did this was to practice Xu Yang's ability to solve problems alone.

Because many students can understand the teacher's explanation, but when it comes to solving the questions, they feel unable to start.

If you want to improve students' scores, you must let them do the questions themselves.

Soon, Ning Chen came up with a new question. This question was the same as the previous wrong question on Xu Yang's paper, with only slight changes.

After Xu Yang read the question, he thought for a while and then started to write.

Because it was a question type that he had just finished talking about, Xu Yang was still able to think of ideas and finished the question within a few minutes.

Ning Chen took a look at Xu Yang's problem-solving process, nodded and said:

Yes, the basic process is correct. It would be better if we pay more attention to the details.

Ning Chen pointed out several areas where Xu Yang's process was not rigorous enough, which may result in process points being deducted in the exam.

Xu Yang's attitude was also very serious and he immediately changed it according to Ning Chen's request.

How about it? Do you want to do the questions by yourself? Is it a different feeling than just listening to the lecture?

Yes, teacher, I feel like I can remember every process of solving the problem better if I do it by myself. I will have to write more in the future.

In the following time, Ning Chen picked a few more questions, explained them to Xu Yang, and asked Xu Yang to do them again on the spot.

Although Ning Chen had no preparations, he was able to answer every question very easily and clearly explained every knowledge point involved. This made Xu Yang highly recognize Ning Chen's professional ability.

In addition, Xu Yang liked Ning Chen's teaching methods very much. In Xu Yang's heart, he basically decided that Ning Chen should be his teacher.

Unconsciously, time passed quickly. When Ning Chen looked at the time, he realized that an hour and a half had passed since class started.

Originally, today was just a trial lecture, but Ning Chen accidentally finished it according to the time of a regular class.

I didn't expect time to fly by so fast, so let's get here first today.

Xu Yang also felt that time passed very quickly. Mathematics was not Xu Yang's favorite subject, but Xu Yang did not feel bored when studying with Ning Chen.

Teacher, I think you speak much better than the teachers in the cram school.

Haha, thank you.

Ning Chenxin said that many tutors in cram schools are part-time jobs for college students, and their teaching abilities are naturally not as good as those of themselves who have several years of teaching experience.

Ning Chen came out of the room and saw Zhou Li in the living room, so she said to Zhou Li:

I accidentally forgot to check the time and it was a bit overtime.

It's okay, Teacher Ning. I see that you two are very devoted to your studies, so I don't have the nerve to disturb you.

Then Xu Yang's mother, I will go back first, and then we will contact you later.

In this case, parents will usually discuss with their children how the children listened today and whether they are willing to continue learning with this teacher in the future.

Teacher Ning, please sit down for a while and I'll go have a chat with Yangyang.

Well, that's fine too.

Zhou Li is a relatively cheerful person, and Zhou Li has a very good impression of Ning Chen, so she wants to quickly select a tutor.

After chatting with Xu Yang for a few words, Zhou Li came out quickly.

Teacher Ning, Yangyang said that you are much better at teaching than the teacher in the cram school, and he is willing to learn from you in the future. Let's make a deal now, and I'll give you today's class fee first.

With that said, Zhou Li took out three hundred-yuan bills and handed them to Ning Chen.

Ning Chen quickly waved his hand and said:

I can't accept the money. I agreed today that it's just for trial listening, and I'll just calculate the money after the formal classes.

Although Ning Chen gave Xu Yang a half-hour lesson today, this was because Ning Chen did not check the time and could not let Zhou Li bear the cost.

It's okay. Anyway, we had an hour and a half class today. It's rare for a child to listen so well. We can't take advantage of you in vain, right? Just take it quickly. If you don't take it, you'll be looking down on me.

Seeing what Zhou Li said, Ning Chen couldn't shirk anymore and had to accept the money.

After setting the time for next class, Ning Chen left Xu Yang's house.

While walking on the road, thinking about the 300 yuan he had just earned, Ning Chen felt that it was quite easy to make money.

This is a job that pays 200 yuan an hour. If you work eight hours a day, it will be 1,600 yuan a day, 48,000 yuan a month, and 576,000 yuan a year...

And this was still in 2010, prices were not that expensive, and the house price in the city center was only about 7,000 yuan.

Thinking that he had a job with an annual salary of more than 500,000 yuan, Ning Chen felt that buying a house was not that far away.

Of course, this is just an ideal state. After all, tutoring can only be done during holidays, and it may not be possible to find so many students.

But no matter what, the money earned by the tutor must be at least enough for Ning Chen to be self-sufficient.

After that, Ning Chen tried two more tutoring jobs, and both were very satisfactory to the students and parents.

After having three tutoring jobs, Ning Chen did not continue to take tutoring classes because Ning Chen still had to set aside enough time to study and do research. After all, this was Ning Chen's main business.

…

As the days passed, Ning Chen maintained a very regular life, but he did not feel that such a life was monotonous. On the contrary, he enjoyed it very much.

Every day, Ning Chen can learn new knowledge. This process of constantly acquiring new knowledge makes Ning Chen feel very happy.

The improvement in the subject level of the system interface and the accumulation of energy points allowed Ning Chen to see his progress more clearly, and he had the fun of playing games, killing monsters and upgrading.

Every time he accumulates enough energy points, Ning Chen will increase his brain power index, giving himself a more powerful brain, and also speeding up the acquisition of subject experience and energy points.

Through further research on the nature analysis of the Sine-Gordon equation, Ning Chen has completed the first draft of the second paper. Of course, because his first paper has not yet been published, Ning Chen is not in a hurry to submit the second paper.

On the other hand, through these days of tutoring, Ning Chen quickly saved more than 10,000 yuan.

With this money as a basis, Ning Chen definitely doesn't need to spend any more money from his parents.

As the Chinese New Year approaches, Ning Chen temporarily ends his tutoring job and prepares to return home.

With the gifts prepared for her parents, Ning Chen got on the train home.
