Back to 90s she made a fortune from scientific research

Chapter 173 I don't think it's necessary to change anymore

"I'm sorry, Classmate Qin, I don't understand this question." Yu Chu was very ashamed, very ashamed, and then quickly promised, "You can ask me again later, I will definitely understand!"

"Okay." Qin Hongfei didn't care, and speculated backwards on the pen and paper, but she couldn't get the correct answer, so she was basically sure, it should be a wrong question, and there was a cross there.

Then move on to the next question.

Twenty questions per page, forty questions on both sides, she swiped extremely fast, if it wasn't for the app, it would have been faster to simply write the answers.

During this period, Qin Hongfei asked Yu Chu a few more questions, and then Yu Chu found that he couldn't answer them, and he was very depressed.

When there were only the last two questions left, Qin Hongfei didn't give up asking her because she couldn't answer them. She pointed to question 39 and asked, "Student Yu, this..."

Yu Chu glanced mournfully, and then burst into tears, she finally understood this question!Very good!She said excitedly, "I understand, classmate Qin, this is a wrong question." She was super confident.

Qin Hongfei guessed the same thing, crossed this question again, and thought to herself, the teacher who gave the question this year is not good.

There are two wrong questions on one paper, I don't know what I was thinking when I wrote the question, sleepwalking?This is easy to delay students, irresponsible, bad review!

The effort of thinking wildly, also counted the last question.

But at this time, during the break in the second class, Teacher Shu asked the students to read silently, and went back to the office to get some things. When he found that Teacher Chang was already there, he told him what Teacher Gao had just come to look for.

Teacher Chang hurriedly stood up while supporting his lower back, and said, "I did take a test paper when I came back. When I was chatting with you, I put it on your desk. Hey, why did it disappear?"

Teacher Shu hurriedly said, "Don't worry, I'll look for it for you."

Then I rummaged through the drawer, found a paper, and immediately smiled, "It's this one." After looking at it, no, isn't this the simulation paper from last semester? She gave Qin Hongfei the paper just now. , why there is another one.

She made a photocopy of this paper on purpose, it's just one copy, it's impossible to make an extra copy!

Thinking about it, he couldn't help but think of the paper for Qin Hongfei, and murmured, "Oh, I might have taken the wrong paper for classmate Qin just now, it's okay, I'll change it now, but there may be a few questions that have been solved... "

Teacher Chang quickly said, "It's okay, just take it back and make a new copy."

Teacher Shu also felt the same way, and hurried back to the classroom to Qin Hongfei's desk and said, "Student Qin, the teacher gave you the wrong paper just now, this one is the right one, change yours for yours."

When Qin Hongfei heard this, she couldn't help but glance at the title of the simulation paper, oh, the paper for the first year of high school.

No wonder she said that junior high school didn't seem to learn these things in her memory, but because of the long memory, she didn't dare to be sure, but she went back and she was silent.

How can I return the paper that is full? It must not be returned. Qin Hongfei said, "Teacher, it's too late to change it now."

Teacher Shu thought she was afraid that she would be angry and blame her, so she said in a soft voice, "What's wrong, you ruined the paper, it's okay, the teacher doesn't blame you if you ruin it, just take it and make a copy gone."

Qin Hongfei said directly, "No, teacher, I have already finished writing this math topic, and I don't think there is any need to change it."
