The fake daughter is also trying to exploit system loopholes today

That is, never cheat. In my previous life, you accused me of cheating in the exam, which made my father completely disappointed in me.

To be on the safe side, Su Yu checked his pockets and the desk before the exam to prevent Su Xiaomeng from tampering with the exam by stuffing cheating notes in them.

Then, in the name of putting the interests of the country above family ties, he reported himself for cheating in the exam, and even cried and talked in a teasing manner, saying that he did this for his sister's good and was afraid that she would go astray.

I bother!

Su Yu recalled the disgusting things that "Su Xiaomeng" had done in her previous life, and couldn't help but spit in her heart.

Soon, the test papers were distributed to everyone. Su Yu picked up the test paper and took a quick glance at it. After making sure there were no printing errors, he took out a pencil and started doing the questions.

First, fill in the blanks: the sum of 9 7s is ( ), both multipliers are 9, and the product is ( ).

Primary school students might need to do some calculations for this kind of question, but Su Yu was a top student who scored over 600 points in the college entrance examination. He got the answer without even reading the question stem.

After filling in two numbers, Su Yu looked directly at the next question without even looking up.

This is even simpler. For every two people shaking hands, three people need to shake hands ( ) times.

Su Yu was unstoppable and in the blink of an eye, he had finished most of the test paper, leaving only the application questions left.

1. Xiao Ming and her desk mate made little red flowers. Each of them made 6 flowers. How many flowers did they make in total?

2. The teaching building is 28 meters high, and the library is 10 meters higher than the teaching building. How many meters is the library? The gymnasium is 6 meters lower than the library. How high is the gymnasium?

The word problems in the second grade were not difficult for Su Yu either. She only took a quick glance and already had the answer in her mind.

Question 2: There are two people, Xiao Ming and his deskmate, so there are 6x12= flowers.

Answer: There are 12 in total.

第二题：28+10=38米，38-6=32米。

Answer: The library is 38 meters and the gymnasium is 32 meters.

With the last period drawn, Su Yu finished the entire math test paper in just two minutes.

"Hoo! Cool!"

After finishing the entire test paper in one breath, Su Yu felt refreshed. He looked around and found that other students were still writing furiously.

Su Yu subconsciously tilted his head and glanced at Su Xiaomeng, and found that she was still counting on her fingers, doing the first fill-in-the-blank question.

Most of the draft paper next to it has been used.

7+7=14，14+7=21

21+7…

Su Yu didn't expect that the seven-year-old Su Xiaomeng was so stupid that she couldn't even replace addition with multiplication. She was very curious about which number Su Xiaomeng had added. She was about to count carefully when she suddenly heard the math teacher's voice from behind her.

"Students, please do not look around or talk to each other during the exam."

Su Yu was stunned for a moment, then realized that the teacher was calling on him, so he quickly retracted his head and pretended to be doing the question seriously.

Seeing that Su Yu admitted her mistakes and corrected them, the math teacher didn't care. After looking at her a few more times, he found that she seemed to have finished the test paper.

"I didn't expect that Su Yu is such a genius. She finished it so quickly. I heard from your class teacher that you were in a very bad school before. I was worried that you would not be able to keep up."

Hearing what the math teacher said, Su Yu's heart trembled and she instantly broke out in a cold sweat. Looking at the math test paper that was filled with answers, she realized that she seemed to have done something very stupid.

The idea is correct to attract the attention of the Su family by improving grades and use good grades to get more attention.

But his grades improved too quickly, jumping directly to the top of the class, which was a bit too much.

After all, before coming to Luanxi Noble Primary School, Su Yu's grades were very poor. In the past half month at the Su family, she mostly studied etiquette and exercised, and did not take any extra classes. There was no reason for her to have such a drastic improvement in her grades.

"Teacher, I haven't finished it," Su Yu said embarrassedly, "It's just that this question is too difficult. I was afraid of handing in a blank paper, so I just wrote some numbers on it. In fact, I haven't even figured out the first question yet."

After hearing Su Yu's explanation, the math teacher was not angry. Instead, he smiled and patted her on the shoulder: "Student Su Yu, don't be afraid. Your foundation is weak. This test paper is difficult. It is normal to have questions you don't know."

"Leave the questions you don't know blank and do the questions you know first. Don't put too much psychological pressure on yourself. The teacher won't blame you even if you hand in a blank paper."

Su Yu sobbed, pretending to be deeply moved: "Teacher, you are so kind, thank you teacher, I will work hard."

Just like that, under the encouraging gaze of his math teacher, Su Yu picked up the eraser, erased all the answers he had written, tried his best to abandon adult thinking, and started to do the questions again.

7+7=14，14+7……

Faced with the first fill-in-the-blank question again, Su Yu did not directly turn addition into multiplication. Instead, like Su Xiaomeng, he added up sevens one by one, counting on his fingers, very clumsily.

Because of the incident just now, the math teacher was very concerned about Su Yu. He would come to check on him from time to time to see if he had made any mistakes in his calculations, whether his problem-solving ideas were correct, and to estimate to what extent he had mastered the most basic four arithmetic operations.

Su Yu was afraid that her math teacher would find out, so she acted desperately, trying to play the role of a primary school student as best as possible.

When the bell rang and the math teacher collected the papers and left, Su Yu was already exhausted both physically and mentally due to excessive mental exertion.

During the ten-minute break, Su Yu wanted to take a short rest, but other classmates were curious about what she had been doing during this period of leave, and whether it was really the same as Su Xiaomeng said. They surrounded her and asked her all kinds of questions, not giving her any time to rest.

"Ding-dong!" The bell rang for class. This class was English class, and the English teacher, like the math teacher, walked in with a large stack of papers.

"Boys and girls, we will have a simple quiz in this lesson."

"The class representative came over and handed out the papers."

No one wanted to take the exam. Amid complaints from the whole class, the English class representative walked up to the podium, took the test paper from the English teacher, and started handing out one paper to each student starting from the first row.

Having learned from the lesson of the math test, Su Yu controlled his speed when doing the questions this time. He thought about each word several times. After ten minutes, he only finished two questions.

Just as he was secretly applauding his own performance, a voice suddenly came from behind him.

"Teacher, I'm done writing and handing in the paper."
