At 9 o'clock, the exam officially started.
Xu You did not turn on the deep learning state, and started answering the questions in a normal state.
The first part is five multiple choice questions.
In order to increase the difficulty, the multiple-choice questions of Wujing are indeterminate choices, which may be single-choice or multiple-choice.
If a question is completely correct, you can get a full score of 6 points.
If it is missed, you can get 3 points.
If you choose wrong, you will not get a point.
Some students, just to be on the safe side, will not choose any option that is not allowed.
Even all the questions are treated as multiple-choice questions.
But for Xu You, this is not a problem to tangle with.
"The first question is to analyze the force of the ladder, and then we can compare it,b."
"The second question is also a mechanical problem, and the synthesis of forces is investigated. Only c is correct."
"The third question, the kinematics image problem, this Dong Chao You shouldn't be wrong, cd."
Xu You answered the first few questions very smoothly.
In fact, the difficulty of the preliminaries is not bad, a large part of it is the knowledge of high school physics, and some of it involves university knowledge.
Soon, Xu You had completed the multiple-choice and fill-in-the-blank questions.
Looking at the time, only half an hour has passed.
But the rest is the most critical part - calculation questions.
In the entire 200-point roll paper, calculation questions accounted for as much as 120 points.
It can be said that whether the calculation questions can be done well is the key to deciding whether to enter the semi-finals.
Six calculation problems, mainly related to electromagnetism, mechanics, kinematics, optics and other parts.
It can be said that every question exceeds the difficulty of the calculation questions in the college entrance examination.
Among them, some advanced mathematical knowledge is also involved.
This is very difficult for some candidates who have not fully studied Wujing.
Some students who usually scored more than 90 points in the physics test were already in a state of being overwhelmed.
Obviously fill in the blanks with the previous choices, but there are still a few more ones to make.
When it comes to the big question behind, why did it start to be outrageous?
Candidates decided to give up struggling one after another and handed in large blank test papers.
After they came out of the examination room, they couldn't help complaining.
"md, I'm not sure about the first question, should I choose c or d?" "I'll choose all the multiple-choice questions, and at least I can get 3 points for the missed ones."
"I'm just a kinematic image What are the big questions in the back? Half of them are electromagnetic calculation questions."
"Yes, it is not easy to do a big electromagnetic question in the usual exams. These six big questions are easy to read just by looking at them." "Headache."
Before the exam was over, there were less than half of the students left in the classroom.
Most of the students participated in the competition with an attitude of participation, and only a few of them really wanted to win the prize.
"Phew~ I'm finally done."
Half an hour before the end of the exam, Xu You completed the answer to the last question.
Xu You breathed a sigh of relief, this test paper was quite enjoyable for Xu You.
It was also a breakthrough for Xu You to be able to finish the answer in two and a half hours under normal conditions.
After all, it is just these six calculation questions, and they are all difficult questions in the college entrance examination.
But after answering the paper, Xu You was not in a hurry to hand in the paper.
He can't guarantee that these answering processes are correct.
Seeing that there was still time left, Xu You began to check the test papers.
It wasn't until the bell rang that Xu You handed in the test paper on time.
After coming out of the examination room, Xu You saw Hu Shucheng standing at the exit.
After Hu Shucheng handed in the paper ahead of schedule, he was waiting for Xu You at the door.
In Hu Shucheng's heart, Xu You is the only object contestant in the fourth middle school that he can fancy.
Seeing Xu You approaching, Hu Shucheng quickly said:
"Damn, Xu You, why did you come out? This is not at your speed! I have been waiting for you for more than half an hour, hurry up, before you forget the answer, Hurry up and write down a pair."
"I checked, so I didn't hand it in in advance."
"Hey, just answer the preliminaries, we will definitely be able to advance at this level."
In fact, if Xu You does not enter the state of deep learning, The speed of answering questions is not as good as that of Hu Shucheng.
While the memory was still clear, the two started the process of answering questions.
"Choices: b, c, cd, cd, d. Exactly the same."
"Fill in the blanks: first question, 1.2, 2.0. Second question, lower than, with the same sign and size..." Face to face, The two found that, except for a few disputes, most of the answers to each other were the same.
Because there will be some steps in the big question, it is impossible to accurately estimate the score.
Counting some process points that may be deducted for big questions, the scores of both of them should be at least 180 points or more.
"How can you enter the semi-finals with a normal score of 120? The semi-finals must be stable. There are still two weeks before the semi-finals. Hurry up and prepare for the semi-finals."
Hu Shucheng was not very surprised by this, after all, both of them Went to the national fair.
If you can't even get close to full marks in the preliminaries, let alone the national competition.
The two were walking and talking, when Hu Shucheng suddenly thought of Lu Zhiyao.
"Hey, Xu You, Lu Zhiyao in your class didn't come to take the exam."
Only then did Xu You realize that he didn't see Lu Zhiyao today.
Because the city's preliminaries were all taken in one examination room, and even Hu Shucheng, who had been guarding the entrance of the examination room, didn't see Lu Zhiyao, so Lu Zhiyao probably really gave up the test.
"She didn't have a high intention to take the exam. Like me, she just started preparing recently. It's normal to give up."
In fact, Lu Zhiyao didn't come to the physical competition sprint class in No. 4 Middle School.
Xu You thought that Lu Zhiyao was just studying on her own, but now it seems that she really gave up.
"At first, I thought that Lu Zhiyao was the most evil in the No. 4 middle school. Now it seems that I was wrong. Compared with you, Lu Zhiyao is still a little bit worse."
"Maybe she thinks that the college entrance examination is the most suitable for her. Anyway, Lu Zhiyao is also the No. 1 middle school, the most likely to pass the college entrance examination and get into Jingbei."
"Well, that's true. There is no hope for the college entrance examination like me, so I put all my hopes on the competition. "
If the college entrance examination is normal, Hu Shucheng can only pass 985, and there is still a certain gap from Jingbei.
"By the way, Xu You, if we can't go to Jingbei, do you have any other plans?"
"Well...haven't thought that much yet."
For Xu You before, even 211 was a luxury, let alone what 985 university he wanted to take.
But to Hu Shucheng's ears, these words changed their meaning.
"Damn, you've already identified Jingbei, right? In fact, the Seven Masters of National Defense are also good. If you want to apply, some majors may be better than Jingbei." Xu You also nodded upon hearing this.
Indeed, Jingbei is not the best choice if you want to devote yourself to aviation, aerospace, military and other industries.
