Two months after joining the physical chemistry team, the teachers collectively gave the selected students a set of questions.

"Today's set of questions is based on the content of the lecture during this time, and we will leave the top ten students through the results of this set of questions. Now start to distribute the test papers, and the students who get the test papers should not start writing first, and when I say start, everyone is writing in unison. Teacher Mei Yin, who teaches Tang Yuyan physics, said.

During this time, there is a small test in three days, and a big test in five days, and the students have already understood the routine of the exam, even if the teacher does not say it, they will abide by the rules of the exam.

In the class of twenty people in classroom 201, Tang Yuyan happened to sit in the first row. After taking the test paper in Teacher Mei Yin's hand with both hands, he began to bow his head and review the questions.

After Mei Yin finished sending the test papers, she looked at her watch, and after the second hand returned to zero, she said, "The exam starts, and the time limit is sixty minutes." ”

After the teacher said to start, Tang Yuyan took the paper and looked at the back first, and after confirming the question type on the paper, she began to write the class and name in the sealed area.

The question types include six single-choice, six multiple-choice, two experimental questions, and three calculation questions, with a total score of 100 points.

Don't look at the multiple-choice question score value adds up to more than 40 points, these points are not easy to get, every small question needs a formula to calculate, reasoning, if the choice is delayed for too long, then the answer question may not have a point.

This set of papers not only tests the students' grasp of the topic, but also tests the students' mastery of time.

Tang Yuyan held the manuscript paper and kept reasoning, calculating, and filling in the answers.

If you encounter a problem with a large amount of calculation, mark it first and move on to the next question. Through this technique, after completing all the questions on the test paper, Tang Yuyan then went back to the previously marked questions.

"There are still fifteen minutes to hand in the papers, students pay attention to the time." Teacher Mei Yin looked at the time on her watch and reminded.

When the teacher reminded the time, Tang Yuyan had already completed all the questions and started the first round of inspections.

Because the three exam times are staggered, all Tang Yuyan is not in a hurry to rush to the next exam room.

"When the time comes, the students will stop writing." Teacher Mei Yin clapped her hands and said.

After hearing what the teacher said, the students also stopped their pens and left the classroom according to the teacher's instructions.

After Tang Yuyan and Yan Yan left the examination room, they briefly chatted about their profound exam questions, and then Yan Yan returned to the classroom, and Tang Yuyan went to another examination room, and then took the chemistry paper.

Xu Kai, who is in the same class as Tang Yuyan, is also a classmate in the chemistry class, and the two get along quite well.

Tang Yuyan appreciates Xu Kai's decisiveness, while Xu Kai appreciates Tang Yuyan's seriousness. The two also became good friends because of the classes during this time.

When Tang Yuyan walked to the 203 examination room, Xu Kai also happened to walk to the 203 examination room from the other side.

"Here, how did you do in the physics test just now?" Xu Kai looked at Tang Yuyan and asked.

"It's okay, only two questions with a relatively large amount of calculation have delayed a little time, and the others are OK." Tang Yuyan said with a smile.

"Hmm." After Xu Kai hummed, he let Tang Yuyan walk into the classroom first.

"I learned about the timing of the preliminary rounds of these three subjects, and all three subjects will be held in the preliminary round next year. Math is in April, Chemistry is in June, and Physics is in July. So, if you pass both Physics and Chemistry, you don't have to worry about exam time conflicts. Xu Kai looked at Tang Yuyan and said seriously.

"Well, then I'll borrow your auspicious words, hoping to pass the exam!" Tang Yuyan replied with a smile.

With the clatter of her heels on the ground, a twenty-seven or eighteen-year-old female teacher walked into the classroom.

"Take out the exam pen, put away the other things, and prepare for the exam." This female teacher is none other than Teacher Wang Ya, who teaches Tang Yuyan chemistry.

When the students were packing up their things, Teacher Wang Ya continued: "I won't say much about the rules of the exam, and everyone should know it in their hearts." ”

The students nodded their heads in agreement.

Teacher Wang Ya's temper is known to Tang Yuyan and her classmates. If cheating is discovered, the fire may not be extinguished.

"Don't be in a hurry to answer the questions after sending the test papers, first check whether the questions on the test papers are complete, whether there are any missing prints, and report in time if there is. When I said to start the exam, the students were putting pen to paper. Wang Ya counted the papers and said after confirming the number of test papers.

The students nodded their heads again, indicating that they were clear.

After getting the test papers, Tang Yuyan still scanned the test papers first according to the usual practice, and there were 12 multiple-choice questions, 9 fill-in-the-blank questions, 7 short-answer questions, and 2 calculation questions in the chemistry test paper.

After browsing the scores of each question on the test paper, Tang Yuyan put the test paper again, prepared to wait for the teacher's password, and began to answer the questions.

After Wang Ya finished handing out the test papers, she looked at her watch, and after pinching the time, she said, "The exam begins." ”

Tang Yuyan picked up the gel pen on the table and began to write the name of her class.

The class and name must be written in advance, otherwise it will be forgotten when the paper is handed in, and it will be a zero score.

There are also many calculation questions in chemistry, for example, the first multiple-choice question: Let NO be be Avogadro's constant, what is the correct statement for 0.2mol/L sodium sulfate solution?

A total of four options are given in the question, which can only be calculated by elimination.

After Tang Yuyan gave time for each big question, she began to do the questions according to the planned time.

"Hurry up, students have 20 minutes to hand in the papers." Wang Ya walked among her classmates and looked around, then returned to the podium and said.

After calculating the last big question, Tang Yuyan looked at the time on her watch, and patted her chest like the rest of her life, there were still 12 minutes left, and there was still time to check.

Tang Yuyan is also meticulous in doing the questions, but because she was nervous when she was calculating the last two multiple-choice questions, Tang Yuyan planned to re-examine the two questions while there was still time now.

"There are still five minutes left, so students should hurry up and check the test papers more so that they don't miss questions." Wang Ya reminded.

Tang Yuyan breathed a sigh of relief after calculating the two uncertain multiple-choice questions.

No problem, just sit back and wait for the papers. Tang Yuyan thought after looking at the steps of answering all her big questions.

After the exam, Tang Yuyan, Qiao Mu, and Xu Kai went back to class together.

After walking to the door of the class, Tang Yuyan and the three knocked on the door.

At this time, this class happened to be a chemistry class, and the chemistry teacher was a middle-aged female teacher in her forties.

Tang Yuyan and the three of them also bowed to the teacher, and then walked quickly towards their seats.

After returning to her seat and finding out the chemistry test questions, Tang Yuyan's mind was still full of the test papers she had just answered.

"Tang Yuyan, come up and answer this question." Zhang Juan, who is also the chemistry teacher in Class A of the first year of high school, looked at Tang Yuyan, who was still in a fugue, and said.
