In the evening, Xia Mang took a walk in the yard of the villa with her father after dinner, but she didn't know that her physics teacher was grading papers without even having dinner.

Every physics teacher has a strong heart, because they may see formulas on the test paper that have nothing to do with the question, and these students always hope that they can guess a few formulas correctly to get some points.

"Oh!" Old Zhang took off his glasses, rubbed his nose and sighed.

The math teacher next to him, Wei Guozhong, hadn't gone home yet and was still writing his lesson plan. "What's wrong with Lao Zhang?"

"Hey, who said that you can get points just by writing down formulas on a physics test?"

"Hahaha, I don't know about that. Didn't we have this when we were in school? I remember that if I had problems solving a problem, I would write down the formula and see how many points the teacher would give me." Wei Guozhong put down the pen in his hand and recalled the ridiculous things he had done in high school.

"Then you should also write down the relevant formulas. Look at this Ye Hao, no matter what formula he writes, he always writes it upwards. You said it was clearly a mechanics problem, but he wrote me an electrical formula. How do you think I should give him a score? Even if I wanted to, I couldn't do anything."

The math teacher also smiled helplessly, "This Ye Hao, there's really nothing we can do. His math is hard to describe. I told him not to do this problem that way, but he humbly admitted his mistake and refused to change."

"But Fu Jing behind him is really good!"

The math teacher smiled and said, "That child's grades are indeed very good and have been very stable, but he's just too worried."

The physics teacher frowned and said nothing. He had not spent as much time with the students as the math teacher, so he did not comment.

“Huh!”

The math teacher was also a curious person. "Whose paper is this... Xia Mang's?"

"You also know this little girl?" The physics teacher said with a smile, holding the physics test paper in his hand.

"Of course I know. She can get a perfect score in math. After I got her monthly exam paper, I went to look for her draft paper. She had written several solutions to one problem on her draft paper."

"That's right. I just took the physics test and found that her paper had the same standard answers. I was shocked. Han Yun did answer it correctly, but his steps were too complicated and not as concise as Xia Mang's. Fu Jing was concise, but he omitted necessary steps, which will deduct points."

The math teacher picked up Xia Mang's test paper and took a look at it. "This little girl is a promising talent!"

"Yeah, I want her to participate in the Oli Tournament! I think she will definitely give us a surprise."

The math teacher smiled and said, "When I saw her math test paper, I thought she was most suitable for math. But now it seems that she is suitable for any subject."

"Her Chinese is not top-notch, but it's pretty good."

"She came back from abroad. We can't be so harsh."

The two teachers discussed in the office that they would increase Xia Mang's learning progress in the future, but Xia Mang is still not worried!

The next morning, the experimental class was in a frenzy!

"I heard that Lao Wei helped Lao Zhang mark our physics papers last night. Not only are the scores out today, but even the rankings are out."

"Ah! How can I live like this? Physics is simply not something for human beings to learn."

"You should ask our math teacher why he wants to get involved in physics."

"Nonsense, mathematics, physics and chemistry have been inseparable since ancient times. Our Lao Zhang and Lao Wei are from the same country."

"Who do you think will win this time, Xia Mang or Fu Jing?"

"I think Xia Mang's IQ is too high."

"I think it's Fu Jing. Xia Mang probably just happened to encounter questions that she could answer during the monthly exam, but Fu Jing is the real boss."

"I say, you haven't woken up yet. Xia Mang is lucky to have good luck in so many subjects at the same time. He is really strong."

"Alright, alright, what are you arguing about? The first period is physics. Just wait for the physics teacher to announce it."

"Yeah, right, let's just wait, it's not us anyway!"

Xia Mang attaches great importance to this physics test because she wants to participate in the physics competition.

In her opinion, it would be boring if the three years of high school were limited to books and college entrance examinations. Participating in competitions can help her meet many like-minded people and understand her own shortcomings. Making friends through books is endless fun.

Xia Mang didn't have to wait long for the results to be announced. The first thing the physics teacher, Lao Zhang, did when he arrived in class was to announce yesterday's results.

"First of all, I want to say that yesterday's questions were similar to those from the Olympiad, but the results surprised me. Aside from a few students who stood out, the rest of us barely grasped the essence of these questions. This is very strange, because our school has special training sessions on thinking in this area every year. It seems like you've given everything you've learned back to the teacher."

"This time, first place went to Xia Mang again, with a perfect score in Physics! Her paper was beautiful. Not only were all the answers correct, but there was no way to deduct points. It was exactly the same as the standard answers. I felt very comfortable correcting her paper. Later, I found her scratch paper from the exam, and do you know what I found?"

"She can give you two or three solutions to the problem you can't solve."

When Lao Zhang said this, everyone looked at Xia Mang in disbelief. Is this a human?

It was already very difficult to solve it, how did she manage to write down several solutions?

"Student Xia Mang, can you tell me why you do this?" This is also what the physics teacher is curious about. Generally speaking, once a person comes up with a solution, he or she will not want to continue solving it, just like completing a task.

Xia Mang felt a little embarrassed. In fact, this was her method of training her thinking and it was also a habit. Every time she did a problem, she couldn't help but wonder if there were other simpler and better solutions.

"Actually, having multiple solutions to a problem is a personal habit of mine. Someone once told me that open-book exams are beneficial. You can try to solve a problem from multiple angles, which can train your thinking. Secondly, if a problem has several solutions, can you really be sure of which one is the answer? So, solve it several times and choose the best solution. Even the strictest grader won't deduct points."

Everyone in the experimental class found Xia Mang’s narration incredible. How could they have time to think about this during the exam?

Han Yun muttered beside him, "What if there's not enough time?"

What could Xia Mang say about this? She had never encountered a situation where she was short of time during a physics exam.

"Isn't that enough? I get an extra hour every time!" Ye Hao muttered, but his voice was not small, making the whole class laugh.

The physics teacher was very disappointed with his student and said, "That's because you don't know anything and can only guess a few multiple-choice questions."

Ye Hao smiled embarrassedly, "Teacher, that's not my fault. I also want to take a good look at them, but I don't know them!"

The physics teacher was so angry at Ye Hao that he ignored him. "Xia Mang, you will represent our class in the Olympiad this time."

"good!"
