Tie Dan felt that this was a novelty, and listened with wide eyes.

"My classmate said that anyone who participated in her training class would have a monthly tuition fee of 300 yuan. Then she didn't give lectures either, and only gave 3 questions. As long as the student completes 1 question, she will return 100 yuan. There will also be a bonus for those who excel. She said that she was not for profit, but only to do an experiment and write a valuable paper. ”

"Very good, I'll sign up. Tie Dan said, and called Yaya and Miaomiao.

"Yaya, what are you busy with?"

"I encountered a physics and mechanics problem, but after doing it for a while, I found that I needed to use the knowledge of high school electromagnetism that we hadn't learned yet, and I was thinking about borrowing a book from the second and third years of high school. ”

"That's right, you come to Sister Chen Ling's house, there is a strange good thing waiting for you. ”

Then Tie Dan called Miaomiao again: "Miaomiao, what are you busy with?"

"I added a foreigner to WeChat. Not old, also a senior in high school, a British boy. I wanted to learn the real British language through voice calls and video chats with him day and night. Don't bother me if you don't have a hundred thousand urgent things!"

"Okay, then you're busy. ”

After Yaya came, she was also very happy to hear Chen Ling explain the details.

Tie Dan and Yaya both added the teacher's WeChat ID. It's called Xuehai Exploration.

The two of them sent a red envelope of 300 yuan to Mr. Xuehai Tanqi. Tanqi sent each of them a question.

Tie Dan received a chemistry problem. There is both knowledge of inorganic matter and knowledge of organic matter.

Chen Ling smiled, went to the bookshelf to find a chemistry textbook for the second and third years of high school, and lent it to Tie Dan.

What Yaya received happened to be the physics question she had just encountered, which was a question involving the knowledge of electromagnetism in the second and third years of high school.

Chen Ling smiled again, went to the bookshelf and found a physics textbook for the second and third years of high school and lent it to Yaya.

When the two high school students said goodbye, Chen Ling waved her hand and said, "Goodbye." Gotta get the prize, maybe a gold bar!"

7 days after tomorrow, Tie Dan and Yaya each received a reward of 2,000 yuan because they had completed the questions sent by Xuehai Tanqi.

"That's too much, teacher. Yaya said politely to Teacher Xuehai Tanqi in WeChat.

"It's fine. This is the money paid by those students who did not finish the questions within 10 days, and it will not be returned, but will be sent to the younger brothers and sisters who have completed it. ”

"Then they'll have a big problem, right?"

"Nope. Although some students only made one question, they also expressed their deep gratitude to me, thanking me for forcing them to go to Liangshan and stimulating them to develop very useful self-learning ability. ”

"Hmm. I appreciate you too. Yaya said.

"You're welcome. I am also grateful to you. ”

Tie Dan also expressed his gratitude to Teacher Xuehai Tanqi, and at the same time expressed his worries: "If the students are all trained to learn on their own, they will all learn by themselves in class, will they not make the teacher angry, right?"
