Chapter 15: Classroom disturbance

　　 After Xu Qiu left the laboratory.
　　 Wei Xingsi called Chen Wanqing to the office and asked:
　　 "What do you think of Xu Qiu's performance in the past two days?"
　　 "Hmm... his scientific talent is quite high, he learns quickly, and he is quite diligent." Chen Wanqing thought for a while and replied.
　　 Wei Xingsi nodded thoughtfully and said:
　　 "Okay, then you will teach him more recently and let him do some basic experiments for you. You can also save time and write your article well. Then you can give him a three-part article for your article."
　　 "Also, please see if he has the willingness to come here to study graduate school, and see if he can stay here. Of course, you have to be euphemistic and don't ask too directly."
　　 "Hmm." Chen Wanqing nodded.
　　 "Okay, then you go back and work." Wei Xing thought.
　　…………
　　Friday morning, the first and second classes are the degree professional class "Material Preparation and Processing".
　　 This course is a compulsory course for the students of the three majors of the Department of Materials. It is taught by Zhou Mathematics, the deputy dean of the Department of Materials.
　　Xu Qiu’s bedroom trio belongs to three different majors in the Department of Materials. Tao Yan is in material physics, and Ren Bin is in electronic science and technology.
　　 Therefore, "Material Preparation and Processing" is also a small number of courses that three people can take together.
　　 They traveled in groups. On the way, Tao Yan curiously said:
　　 "Binzi, you used to wake up all the time and then get up for lunch, why did you get up so early today?"
"Hey, Zhou Mathematics called me in last week's class, and asked classmates who knew me to give me a message in class, saying that I will be called next time, do I dare not go to this class?" Ren Bin said .
　　 "Hey, has he ever said that, why don't I remember." Tao Yan said.
　　 "Brother, because you skipped class too." Xu Qiu couldn't help but interject.
　　 Tao Yan patted his forehead and suddenly realized:
　　 "Oh, I remembered. Last Friday morning, I accompanied my sister to the school hospital. It was almost half past nine and didn't go to class."
　　 Xu Qiu and Ren Bin looked at Tao Yan with contempt.
　　 Tao Yan hurriedly said: "No, I don't have one, listen to my explanation..."
　　 Ren Bin stretched out his hand and patted Tao Yan on the shoulder, and said, "No need to explain, we all understand."
　　 The three arrived in the classroom a few minutes earlier.
　　 "Material Preparation and Processing" is a big class for more than 80 people. The seats are quite tight, so they didn't find an empty place for the three companies, so they found separate places to sit down.
　　 Every class of mathematics is called.
　　 But he is not the kind of teacher who reads one by one with a roster. According to him, that would waste a lot of teaching time.
　　 He talked about a certain point of knowledge, and when he came up with a question, he would randomly call a classmate to answer it.
　　 If the answer is correct, 1 point will be added to the usual grades, and no points will be deducted. If no one responds, whether it is skipping class or falling asleep in class, 3 points will be deducted.

　　The first class was about half an hour later.
　　 Zhou Mathematics scanned the students below, a few were sleepy and yawning, and a few were lying directly on the table with their heads down.
　　 He intended to refresh the students, so he said:
　　 "What is the difference between thermoset and thermoplastic? Let's find someone to answer."
　　 He took out the roster, looked through the roll call in the last class, and found a classmate who had a cross.
　　 "Ren Bin, is classmate Ren Bin here?" Zhou Mathematics asked.
　　 Ren Bin raised his hand to signal, and then stood up.
　　 Zhou Mathematics: "What question did I ask just now?"
　　Ren Bin was just wandering. He didn't know what the problem was. He stood there pretending to think for five or six seconds, and said:
　　 "Teacher, I don't know."
　　Zhou Mathematics: "Okay, please sit down and pay attention to the lecture in class."
　　 After this wave, the students really became energetic and began to secretly exchange the content and answers of the question just now. Even the sleeping student was called by a friend next to him.
　　 Zhou Mathematics drew a circle after Ren Bin's name on the roster, and then randomly picked another name.
　　 "Xu Qiu, is classmate Xu Qiu here?"
　　 Xu Qiu stood up calmly, this kind of common sense question is not difficult for him at all.
　　 Zhou Mathematics: "What question did I ask just now?"
　　 Xu Qiu: "The question the teacher asked just now was'What is the difference between thermosetting plastics and thermoplastics?' The answer is, one is insoluble and infusible, and the other is soluble and fusible."
　　 Zhou Mathematics nodded: "The answer is correct, please sit down."
　　 then drew a triangle after Xu Qiu's name.

　　The course is in the last few minutes.
　　 Zhou Mathematics patted the desk and waited for a while, after most of his classmates’ attention shifted to him, he continued:
　　 "The course content of this course has been introduced to the students today.
The next class is a question-and-answer class, and the exam week will come later. The test date of our course is tentatively scheduled for one month. This classroom is a bit small and can’t fit so many people. It may be split into two classrooms. .
　　The test mode is a closed-book test. The specific time and location will be sent to you by email after I confirm with the Academic Affairs Office. "
　　 The students below heard him say "send mail", their faces changed.
　　 According to the seniors of the previous year, Zhou Mathematics is very strict. After their grades, more than 80 people have 2 A, 3 A-, 34 F...
　　 The most embarrassing thing is that Zhou Mathematics also sent the list of students who have not been in the subject by mail to everyone in the class.
　　 Later, his explanation was that the wrong group was selected when sending.
　　 Fortunately, after the start of the school make-up exam, all 34 people who failed the subject passed.
　　The Academic Affairs Office of the Magic City University stipulates that for courses with more than 5 students, the A and A-points cannot exceed 30% of the total number of students who choose the courses, but there is no stipulation on the proportion of F points for a course.
The converted grade points of A, B, C, D, F are 4.0, 3.0, 2.0, 1.3 and 0. With +, increase by 0.3, and with -, decrease by 0.3. The total grade point is the average of all course grade points weighted by credits value. UU reading www.uukanshu.cóm
　　 Among them, there is no D+ in grade D, only D-, D- means failing and passing the make-up exam, F means failing and failing the make-up exam or failing due to lack of exam.
In order to prevent students’ grade points from being too ugly, many teachers first give full 30% of A and A-, then 40% to 60% of B+, 10 to 30% of B and B-, C and D. Grades are not given or only given to one or two students, and F will only be given to students who cannot read the test results or miss the exam.
　　 Normally, teachers like this are also called "B+ Unlimited" teachers, and they are very popular in the first semester.
　　 Some predecessors even developed a software called GPATOOL, which counts the historical points of many teachers, which can be used as a reference for students when choosing courses.

　　 After class, Ren Bin finds Xu Qiu and Tao Yan.
　　 "This course actually has more than 500 pages of PPT, and it is still a closed-book exam. Xu Qiu, you must help me, if I fail again, my grade point will be 1.9." Ren Bin said.
　　 "Okay, I will help you keep your keyboard and mouse when I go back, and I will return it to you after the exam." Xu Qiu said.
　　 "This is not so good..." Ren Bin hesitated.
　　 "This course is mainly about backing knowledge points and it takes a lot of time, so this should be the best way." Xu Qiu said.
　　 "Well, listen to you." Ren Bin seemed to have made up his mind.
　　 "Binzi, don't panic, and there is me. When I finish reviewing, I will send you the summary materials." Tao Yan interrupted.
　　 "Tao Yan, you will also review it? Didn't you take the exam before naked?" Ren Bin looked disbelief.
　　 "This semester's grades will also affect the results of the graduate program, so I can only fight for it. I am not as high as Xu Qiu." Tao Yan shrugged.
