my scientific age

Chapter 71 Is the perfect score as you expected?

At this time, Lin Wan, who was doing English papers next to her, felt her wrists were sore. She put down the pen and rubbed her right hand. She looked up and looked around. She immediately found Yu Hua who was facing the answer, a little surprised: "Yu Hua, are you correct?"

surprise.

deeply surprised.

How long has it been since Yu Hua got the real exam paper and finished it?
Lin Wan, who has excellent eyesight, can see the content of the math test paper on Yu Hua's desk, and can see that Yu Hua is not copying the answers, but comparing the answers.

Moreover, copying the answers has no meaning for the third-grade students who are about to graduate and meet the most important test in their lives. At this time, if they get full marks for copying the answers, can they also get full marks when they take the school's independent examination?
"Well, it's done." Hearing Lin Wan's voice, Yu Hua nodded with a smile.

Lin Wan asked curiously, "How was the test?"

The speed of doing the questions was so fast that Lin Wan couldn't help but wonder about Yu Hua's math grades.

During this period of contact, Lin Wan had a basic understanding of Yu Hua's preferences, that is, mathematics.

"Not bad, within my expectations." Looking at the simulated results of the real test paper, Yu Hua said to Lin Wan, a faint smile appeared on the corner of his mouth, and he was satisfied.

It became.

The mathematical foundation of high school has been completely laid, and there is no obstacle.

In this 1936 National Central University math exam paper, Yu Hua has at least three solutions to each question, and even four solutions to the last question. From today onwards, elementary mathematics, which he mainly studies in high school, can no longer stumped him.

If you use words that are biased towards the field of metaphysics, now Yu Hua can call it - the realm of elementary mathematics is complete!
"As expected?" Lin Wan heard this, she couldn't laugh or cry, what kind of answer is this?
"Student Lin Wan, I'll go first, I have something to do today, bye, thank you for your real test paper." Yu Hua smiled at Lin Wan, thanked him softly, and immediately packed up his things without delay, got up and left.

This weekend, there are a lot of things to do. First of all, I will go to Huangchenggen Bookstore to get back the printed set of math errors. Then I will go to the temporary workshop outside the school to make the official version of the portable lighting source.

After realizing the importance and scarcity of drafting standards, Yu Hua did not save the trouble and faked the overall structural design drawings he made, but prepared to make them himself.

Making it by hand is at best a hassle. If this overall structural design is circulated, once you expose yourself, the consequences will be disastrous.

Under the background of knowledge blockade, the design drawings containing the drafting standards are too important. Before the drafting standards compiled by oneself have not been officially published, their true identities must not be revealed.

Yu Hua hurriedly left. Lin Wan was the only one left in the reading room on the second floor. This weekend, many students took advantage of their vacation time to go back to visit relatives. Lin Wan still came to the library to study as always.

Without making a sound to ask what Yu Hua was doing, Lin Wan quietly watched Yu Hua walk out of the reading room, and her figure disappeared at the door. She smiled and shook her head, looked away, and prepared to continue her study of English. She was holding a pen in her right hand and was about to write when she stopped suddenly, a pair of clear and clear eyes. Bright eyes turned to the desk next door.

The real exam papers and answers of National Central University were not taken away, and they lay quietly on the surface of the desk.

have a look?

Humans are curious creatures, and Lin Wan is no exception. She had done this real test paper before and scored 78 points. After thinking about it, she put down her pencil, got up and went to Yu Hua's desk, looking at the real test paper full of handwriting. test paper.

The characters are in block letters, which are upright and atmospheric, revealing an ancient rhyme, which is very beautiful.

"This is?!"

There were no grades in the opening area of ​​the test paper, there were only tick-marked math questions. Lin Wan glanced at it, her brows slightly wrinkled, and she felt that things were not easy.

There are a lot of math questions ticked on this test paper.

Lin Wan was even more curious in her heart, holding the answer of the test paper in her right hand, looking at the first multiple-choice question, comparing the answers.

The first question is correct.

Second question, correct.

The third question is correct.

The fourth question is correct.

The fifth question is correct.

All multiple-choice questions are correct, what about fill-in-the-blank questions?

After Lin Wan checked the multiple-choice questions, she immediately turned her attention to the sixth question. She clearly remembered that this was where she started to make mistakes. The first three questions were all wrong, and the last three questions were all wrong.

The sixth fill-in-the-blank question is correct.

The seventh fill-in-the-blank question is still correct.

The eighth fill-in-the-blank question is still correct.

After comparing the first three questions, Lin Wan felt a little scalp tingling. She pursed her lips and looked down. Questions [-], [-], and [-] were all correct. Questions [-], [-], and [-] were still correct. All right.

Fill in the blanks, full marks!

The score of the math test paper is very good for judgment. It is different from the national language and party morality that need to be studied in the article to understand. The topic of math is right, wrong is wrong, and there is no ambiguity.

too exaggerated.

Are you a human?

Lin Wan couldn't help swallowing her saliva. Rao was the top student in the school. Looking at the real exam paper in her hand, she couldn't help being surprised and shocked.

The line of sight continues to move, and the next part is the most difficult part of all the math exam papers, the math questions.

There are seven calculation questions in total, with the highest proportion of test paper scores. It is also a headache for many literature students in the class. When many people encounter calculation questions, they have already been impetuous by the previous multiple-choice questions and fill-in-the-blank questions. Come to the calculation question, yes, the question knows me, I don't know the question.

Lin Wan was very curious about the errors in Yu Hua's test paper, but when she turned her attention to the calculation section, she couldn't help rubbing her eyes, wondering if she was dazzled.

what is this?
what is this?
What the hell is this? ! ! !
Lin Wan couldn't believe what she saw, she was a little incredible, a little unbelievable.

In the calculation part of the test paper, there is not a single cross, all are tick marks. There are no exceptions for the seven calculation questions. Mathematical symbols and formulas full of block letters constitute the blank area of ​​the test paper, and the formulas and solutions are all listed in a column.

The calculation problem is not enough to get full marks if you give the answer, you must write a complete problem-solving process.

Now, the problem-solving process is in front of Lin Wan.

The most important thing is that the problem-solving process given by Yu Hua is different from the problem-solving idea and process that he thought about at the beginning, but the answer is correct.

This shows what?
Yu Hua's math level is far higher than hers.

"So, the full score is what you expected?" After calming down a little, Lin Wan carefully studied the problem-solving process of each question, and the confusion and confusion before suddenly became clear. Suddenly, Yu Hua's confident smile appeared before he left, and the corners of his mouth twitched slightly.
