"Okay, that\'s all for the new lesson. Now let\'s have the practice to check what you have learned in this lesson."

All the classrooms in Colin High School were equipped with projection equipment. Ms. Acheson projected several questions for students to do.

After a while, Ms. Acheson asked, "Are you finished? Now let\'s look at the first question."

Immediately, a student raised his hand and answered the first question. Ms. Acheson was very satisfied. She explained the solution to the first problem to her students briefly and continued to ask the following questions. She was giving another chance to another student to give their answer.

Sophia saw Melissa at the next table, working out the second question. She glanced at Melissa\'s answer and saw that it was correct. She made a gesture to Melissa, indicating her to put her hand up and answer the question.

Melissa was less sure about her answer. But as Sophia encouraged her, she raised her hand.

Ms. Acheson was surprised, and then smiled, "Melissa. Have a try."

"Is the answer quarter root six?" Melissa said.

"Good. That\'s right." Ms. Acheson happily announced it.

Molly glanced at Melissa and whispered disapprovingly, "I raised my hand... I should have been picked."

Sophia quietly gave Melissa a thumbs-up in praise. This made Melissa instantly happy, and her eyes crinkled up, and she smiled broadly.

When it came to the last question, none of the students in the class raised their hands.

This question was very difficult. Ms. Acheson had told them that it\'s difficulty was about the level of the college entrance examination. It could not be solved by using the sine and cosine law alone, but they also needed to apply the knowledge they had learned before.

Ms. Acheson was a little disappointed, "Has anyone worked it out? Or just had a go? We have learned all the knowledge points one needs for this question. Try to have a think and give me an exact answer, "

Molly glanced back at Sophia unkindly and suddenly said, "Ms. Acheson, I saw Sophia do it. She was just embarrassed to say it!"

She had just looked back and seen the blankness of Sophia\'s sheet of paper. If Sophia was asked to stand up to answer this question, she would definitely make a fool of herself for not having an answer to give!

Ms. Acheson frowned slightly, "Molly. You can\'t get other students to answer questions. This is a violation of our behavior code, and you know that?"

Molly flushed and looked down. She didn\'t dare to speak again.

Ms. Acheson looked at Sophia. She had seen Sophia doing math problems before and thought her math was good, so she asked, "Sophia, have you worked out this question?"

Sophia had to stand up. She knew that Molly had deliberately set her up to get her back for math book palava.

"The answer is root three-seconds plus one! Ms. Acheson."

Molly snorted contemptuously. This problem was very difficult. She had made a few auxiliary lines on her rough paper and thought for a long time but still could not come up with a solution. Sophia hadn\'t written anything on her paper. How would she be able to get the right answer? Mental arithmetic? This question couldn\'t be solved by mental arithmetic.

As she thought this, she suddenly heard Ms. Acheson said, "That is the right answer. You may sit down."

Molly was confused. How was it possible? If she couldn\'t work out such a difficult question, how could a bad student like Sophia be able to do it?

Ms. Acheson explained the solution to the problem to the students in detail. But many students still did not understand. Even after she had repeated it, there were still many students who could not get it.

After finishing the exercise, Ms. Acheson said, "I want to take a moment to praise one of our class: Sophia. As some of you may be aware, she was in a terrible accident two years ago and woke up just before the summer vacation. The question we just looked at is very difficult and she was the only one to work it out by herself. I can only imagine how hard she must have studied when she woke up to make such wonderful progress. This kind of hard-working attitude is worth learning from."

***

Sophia felt a bit bad, and she hadn\'t tried; any effort had been in her previous life. She had been so overwhelmed by the joy of being in a body that could freely move that she had just run around all day and never read a book ever since she woke up.

Ms. Acheson continued, "So I have decided to ask Sophia to be our class\' math representative. Would anyone like to comment on that?"

A few of the students who were hoping to be the math representative themselves were surprised and a bit disappointed. But no one directly stood up against it. Even Molly could not say anything. After all, that question had proven Sophia\'s strength in math. She couldn\'t match her.

Sophia had somehow become the math representative for her class. She didn\'t really know what the class representative should do. She had never been a class representative before. In her previous life, she studied well, but she was paralyzed and couldn\'t move freely and so had stayed out of that side of school life. And the other Sophia Green had been a troublemaker. No teacher ever asked her to be a class representative.

She imagined that the class representative probably assisted the teacher, giving out and collecting homework and other things like that.

After class, the Sister Alliance gathered around to congratulate Sophia. The elections were in the afternoon and yet she was just elected as the math representative in the first period of the day

Carol Carter, who had been a class representative before, explained the role to her. Besides giving out and collecting homework, class representatives had a few other responsibilities, but mainly they just did whatever the teachers wanted of them.
