Chapter 3 Midterm

The night before the midterm exam, Cheng Zhou fumbled through his class notebook in the office.Thinking of tomorrow's exam, her heart pounded, and her palms sweated from nervousness, as if tomorrow's exam was not a mid-term exam for a professional course, but a college entrance exam that was said to last forever.

When it was close to eight o'clock, Zhou Yuning stretched his waist, yawned and said, "No, I read the literature for a day, and the amount of information is really too much. I'm going back to recuperate."

"Sister Zhou, let's go together, do you want to eat Liangpi? The Liangpi in the small noodle restaurant is very good, and the tofu and barbecue are also spicy enough. It's in the snack street outside the school gate." Wang Xiaonan suddenly became active.

"You still tell people not to lose weight! Wang Xiaonan, let me tell you, I really haven't lost weight today."

"Come on, come on. Do you want to go with me, Junior Sister?"

"Senior sister, I won't go." Cheng Zhou looked up pitifully, "Tomorrow is the midterm exam, and I haven't finished my review yet."

"Eh?" Zhou Yuning put on his coat and leaned in front of Cheng Zhou to look at it, "The phase diagram of the binary system... Isn't this materialization? Let me tell you, Gu Yazhen got full marks in the middle and end of the materialization period. You also did all the additional questions correctly. You should make good use of such a good resource, junior."

Although one of Zhou Yuning and Gu Yazhen is a master student and the other is a doctoral student, they are also students of the same level.Both of them studied in this school, so Zhou Yuning knew Gu Yazhen's glorious deeds well.

She turned her head and shouted into the corner, "Yazhen, hurry up and show the demeanor of a senior sister, come and help junior sister."

Cheng Zhou took advantage of the situation and looked back, only to find that Gu Yazhen did not respond.At this moment, she lowered her eyes and the corners of her mouth twitched unnaturally.

Zhou Yuning and Wang Xiaonan have long been familiar with it.The two of them laughed and left the office shoulder to shoulder, and the room became quiet again in an instant.Sitting alone with Gu Yazhen in the empty and quiet office, Cheng Zhou couldn't help feeling a little nervous.

A few minutes later, the rattling sound of the rolling wheels on the swivel chair behind him broke the oppressive air that was about to solidify, followed by the soft sound of the sneakers stepping on the ground.

Gu Yazhen walked lightly, and her actions were always elegant and quiet. She walked to Cheng Zhou's table and sat down, with her white and slender hands hanging on the edge of the table, and asked softly, "Can I have a look?"

"...Yes, yes, you can read all of these." Cheng Zhou, who suddenly pulled away from his wild thoughts, lost his footing for a while, was taken aback by the senior sister's concern, and hurriedly pushed the textbooks and review materials forward.Sister, what are you going to do?

Seeing Cheng Zhou's embarrassment, Gu Yazhen smiled lightly, and took Cheng Zhou's textbooks, notes, homework and review questions from the table several times.She opened the document carefully, flipped the pages quickly, and her eyes under the long eyelashes turned left and right.

While Gu Yazhen was staring at the document intently, Cheng Zhou quietly raised his eyes to look at her face.When Gu Yazhen was serious about something, her expression naturally relaxed, without the obvious tension and indifference, and her hidden intelligence gradually revealed.In the past, the aura of Xueshen was too strong, and Cheng Zhou had never observed her carefully, but now looking at her exquisite and outstanding facial features, Cheng Zhou only lamented the injustice of God's creation.

"Where did this outline come from?" Gu Yazhen raised her head, her clear eyes accidentally met Cheng Zhou's examining eyes.Before Cheng Zhou, the voyeur, could react, Gu Yazhen lowered her eyelids first, and turned her eyes away.

"Oh... I bought it at the campus bookstore. The bookstore has a lot of notes and review materials for various courses, and it's not expensive. I bought this book for only 10 yuan. Have you bought it, sister?"

"No." Gu Yazhen shook her head.

Cheng Zhou realized that he asked a stupid question.How could Xueshen buy other people's notes and summaries?

"This outline is not well done." Gu Yazhen frowned slightly, "It just lists all the knowledge points in the textbook by chapter, which is no different from copying a textbook."

"Well... Sister, I want to ask, do you still keep your materialized notes and outline?" Cheng Zhou swallowed, looking expectant.

"Hmm. Do you mind if I scratch your book with a pencil?"

"Not at all, just row."

Twenty minutes later, Cheng Zhou looked at his unrecognizable textbook, his jaw almost dropped.

"This paragraph is nonsense, it is impossible to test, I will cross it out for you."

"The formula is too long, there are too many parameters that need to be substituted, and the practicality is very low. I will cross it out for you."

"This paragraph is used to enrich your knowledge. If there is no test point, I will cross it out for you."

"Deduce the intermediate process formula, cross it out for you."

"...cross out."

Looking at the large and small silver-gray crosses in the textbook, Cheng Zhou estimated that there were only about [-] pages left in the [-]-page book.

"Senior Sister, how do you know which ones are important..." Cheng Zhou felt mixed feelings at this moment.

Gu Yazhen turned the outline to the reverse side, and explained to Cheng Zhou while writing on the blank page: "Every book, whether it is a novel or a textbook, is telling a story. It has a story line and the author's intention to express. .From the beginning to the end, sort out a main story line and a few branches, which together form a complete knowledge point; after understanding the story, you will naturally understand the author's intention, and that is the test point."

Cheng Zhou focused on the delicate handwriting that Gu Yazhen left on the paper, and copied it carefully in his heart.Starting from the contents of the textbook, Gu Yazhen set up a systematic story framework for her, combining the knowledge points of each chapter meticulously and logically.When the story line was closed, Cheng Zhou seemed to be enlightened, and really connected all the points in his mind.

"Senior Sister, you are too amazing..." Cheng Zhou jumped with joy, as if he had discovered a new continent, "I want to go through all the knowledge points based on your summary."

"Okay," Gu Yazhen stood up, and pointed to several large notebooks on Cheng Zhou's desk before leaving, "In the future, don't copy the textbooks into the notebooks, and then use colorful pens to copy the contents of the notebooks to other books. On a notebook. It's too time consuming."

Cheng Zhou couldn't help blushing, and awkwardly stuffed the notebook into the drawer and locked it.

----------

The next day, the materialization midterm exam was held in class, and the invigilators arranged seats for everyone according to their student numbers, with an empty seat between students in the same row.

Chen Junhan complacently sat down on the seat next to Brother Shui with a stationery bag and a water glass, and did not forget to give Brother Shui a fist: "Brother Shui, please take care of me later, and remember to move the paper to my side when you finish writing it." move."

Brother Shui has water in his name, but he doesn't have water in him at all. It is not in vain that Chen Junhan is so ecstatic that he has been contracted to be the top three in his grade for two years.

Zhong Qi sat behind Chen Junhan, and repeatedly told Chen Junhan to hang her hands and lean on the back chair after copying, so that she could straighten up and read the paper in front of her.

Cheng Zhou sat behind Zhong Qi and Xie Feifei in front.She squeezed her sweaty palms, stared at the textbook in front of her in a trance, doing the last struggle before the exam.Her heart was almost jumping to her throat, and she didn't even notice the soaring resentment behind her and the eye knife that cut her into pieces.

Xie Feifei stared at Cheng Zhou's back, holding back her full of resentment, and hesitated to speak.After hesitating again and again, she poked Cheng Zhou's back with the cap of her pen: "Zhou Zhou, is it okay to put the paper in an obvious place after finishing writing? I want to check the answer with you."

"I'll try my best." Cheng Zhou whispered softly, like the sound of nature.

Xie Feifei only felt that it was harsh.She rolled her eyes and gave Cheng Zhou a venting gesture.

"One test paper for each person, both front and back; three answer sheets, write on the back if there is not enough space for the answer; two draft papers; a total of ten major questions and two additional questions, all of which are question and answer questions." After falling, many students in the classroom gasped.

There are no multiple-choice questions and true-false questions, and the chance of getting zero marks is really within your reach.

"Now you can start answering the questions. The exam time is two classes, plus the break time, a total of 100 minutes."

Cheng Zhou took a deep breath and roughly scanned the ten big questions.The first few questions are very simple, similar to the sample questions for after-school homework. As for the latter few questions, she is not sure yet.

It took her about half an hour to complete the first seven questions. If there is no mistake in the calculation, there is no problem in passing.After relaxing a bit, she began to study the last three difficult problems.

At first glance, these three big questions may not seem to have been done, but when you think about it carefully, they are actually related to the three hidden important knowledge points highlighted by the senior sister last night.Cheng Zhou's hand holding the pen trembled.As if hiding a big secret, she hurriedly finished the three questions, ignoring the scribbled handwriting.

By the time the ten major questions were written, seven or ten minutes had passed for the exam.This is the first time Cheng Zhou has finished the test paper so early.She raised her eyes and looked around. Everyone was writing vigorously, and the fountain pen of the classmate beside her was still stuck on the eighth question on the answer sheet.
