The final exam has finally arrived, and in order to get a good score, all the students have done their best.

In addition to the normal answer sheets during the exam, many students also prepared cheat sheets.

For example, the key exercises drawn by the teacher before are cut out of the textbook and then hidden in a pencil case or trouser pocket, and some simply hide the textbook in their clothes and bring it into the examination room.

The boys wore clothes that were looser and easier to hide, while the girls were a little more troublesome.

However, girls have a better advantage than boys, that is, they can hide the cheat sheet in stockings, and on the day of the exam, almost all girls who love to wear short skirts on weekdays will change into long skirts, and girls who usually wear high necks often change to low necks on this day.

Moreover, most girls with long hair will not wear whips to cover the sky, but will naturally spread their long hair on their shoulders and hide their ears.

Of course, no matter how smart a student is, he or she is certainly not as smart as a teacher.

Teachers actually evolved from students, so when they looked at the dresses and eyes of their classmates, they knew what little Jiujiu was hiding.

The reason why they are silent is that they don't want to worry about these children, and if the teacher really wants to be serious, the students will never have a chance to cheat.

Although Ji Ran's review was not bad, but, for the sake of insurance, he still prepared a few cheat sheets, one on the outside of the stockings on each leg, and then a cheat sheet behind the left ear, and a copy in the bra in case of emergency.

Chen Lili was even more exaggerated, and actually wrote the cheat sheet directly on her thigh, as soon as she lifted her skirt, she could see it.

Chen Xiaoyin is more regular, but she didn't prepare a cheat sheet, but Ji Ran really sweated for her.

Although Xiaoyin girl is very smart and belongs to the more intelligent type of girls, however, Wanwan's high school education is much worse than that of the mainland, so if Xiaoyin girl wants to catch up with half a semester of study, it is basically very difficult.

In this final exam, if Xiaoyin's sister is not "prepared", it is possible to fail the course.

However, Xiaoyin's sister didn't believe that she would fail the course, so she insisted on answering the questions independently.

The exam began in a tense atmosphere.

Examinations are ranked according to the results at the time of admission.

Ji Ran's grades are still in the middle of the upper reaches, with the student number in the twenty in the class, Chen Lili in the thirty-fifth, and Du Ziteng in the forty-second.

When entering the examination room, Du Ziteng quietly walked over, gently tugged Ji Ran's skirt, and whispered: "Xiao Ran, help, after you are done, give me an answer." ”

Ji Ran looked at Du Ziteng's bitter gourd face, and thought that this kid was just not ready, he was either working or playing games this semester, and he must have fallen behind a lot in his studies.

"Okay, I'll try." Ji Ran said to Du Ziteng.

"Is the note ready?" Du Ziteng asked in a low voice.

"Notes? No, will you use calculus paper then? Ji Ran said that because it is a science and engineering exam, it will involve a lot of calculations, and when the time comes, the exam will issue calculation paper.

"Don't, use mine." Du Ziteng said, quietly stuffed a few prepared notes into Ji Ran's hand, and squeezed Ji Ran's little hand tightly, "Xiao Ran, please." ”

Ji Ran smiled and nodded, clipped the note to the skirt, and then went to his seat.

Du Ziteng sat down at the adjacent table not far from Ji Ran.

"Please." After Du Ziteng sat down, he quietly arched his hand at Ji Ran.

Ji Ran smiled and made an OK gesture.

As the exam bell rang, the exam finally began.

The teachers handed out the test papers and returned to the podium.

However, when the teacher turned around and returned to the podium, what Ji Ran didn't expect was that Du Ziteng actually copied the textbook directly under the volume.

He is really bold, and he copied so fiercely at the beginning of the exam.

Ji Ran is not in a hurry to do his own test papers, many of the questions in the test papers are actually what the teacher usually says, and, before the exam, the teacher has marked the key points, as long as you usually listen carefully, in fact, the question is not very difficult, even if you forget the answer, as long as you follow the steps taught by the teacher, recalculate, you can also get the correct answer.

Ji Ran gradually entered the state and filled in the answers one by one into the test paper.

In fact, she only came in the middle of the semester, and she couldn't keep up with some of the previous questions, and the calculation of many topics needs to involve some permutations and combinations in high school and the relevant knowledge of limit algorithms, in fact, this algorithm for finding the limit has already involved the field of calculus, and calculus is a course that can only be learned in college in Wanwan, so Xiaoyin feels very difficult.

How can you calculate complex problems without math tools?

Chen Xiaoyin encountered several problems in a row, which was really a headache, especially when she saw a few questions with huge scores at the back of the test paper, she had a feeling of being loveless.

Almost all of the big problems in the back require calculus, which is simply difficult for exchange students in Wanwan.

Ji Ran was answering the question, and at the same time, she also felt the difficulty of the question, she quietly looked back at Chen Xiaoyin, Xiaoyin's sister was biting the tip of the pen, and her willow eyebrows were frowning and calculating the question.

Clearly, she was in trouble.

Du Ziteng, who was not far away, saw Ji Ran turn around, coughed deliberately twice, and then quietly hooked his hand at Ji Ran, signaling Ji Ran to quickly pass the answer to him.

Ji Ran shook her head and pointed to her test paper, in fact, she hadn't finished answering it herself.

Du Ziteng scratched his head anxiously, he copied what he should have copied, and he almost copied what he should have been, but he was still more than 20 points away from passing, as long as Ji Ran passed a few of the multiple-choice questions and the last few big questions, it was estimated that he would be able to pass it almost immediately.

Du Ziteng waited in torment, looking east and west, anxious like ants on a hot pot.

The teacher sitting on the podium glanced at the examination room, and then said: "Students who have finished answering the paper should not look around, affecting the answers of others, if you think it is no problem, you can submit the paper in advance." ”

Hearing the teacher's reminder, Du Ziteng hurriedly lay on the table, put his face on the test paper, and turned his head to look at Ji Ran.

Looking at Ji Ran, who was seriously answering the question, Du Ziteng felt a beautiful feeling in his heart, and it seemed that only at this time could he appreciate her quietly, right?

Finally, Ji Ran's answer sheet was completed, she shook her somewhat sore wrist, carefully checked the test paper, and after confirming that there was no problem, she quietly took out the note from the skirt and quietly wrote her answer on the note.
