I Have a Research Support System

　　 After taking a shower, he returned to the bedroom again. Xu Qiu saw Ren Bin sitting at the computer desk, wearing headphones, and using the touchpad to operate the laptop.

　　 Is this guy playing games again?

　　 Xu Qiu walked over and found that Ren Bin was reviewing while listening to music, so he patted him on the shoulder.

　　 "Xu Qiu, you scared me." Ren Bin shivered and took off his headphones.

　　 "What about review?" Xu Qiu said.

　　 "Which is reviewing, I am previewing." Ren Bin frowned and said, "These professional courses are too difficult."

"Wait, what are you looking at? Suppose f(x) is continuous on (-∞, +∞), and for any x, f(2x-f(x)) = x, prove f(x) ≡ x+c." Xu Qiu said: "Isn't this the content of mathematical analysis?"

　　 "I haven't done mathematics analysis, physical chemistry, and C programming yet. I quickly rebuilt one this semester, otherwise I'm afraid the department won't let me graduate." Ren Bin scratched his head.

"Mathematical analysis is to do more questions, such as Ji..." Xu Qiu originally planned to recommend Jimidovich to him, but after thinking about it, he didn't seem to be suitable for him, so he asked: "Which college teacher did you choose? The number of colleges, or the college of computer science? Teachers from the college of accounting give the branch better."

　　 "The selected teacher Zhang Wei should be from the Academy of Accounting." Ren Bin said.

"Ms. Zhang Wei is notoriously good at giving points. When you finish the final exam, fill in the test papers and don't leave blanks. Zhang Wei sees that you are a junior, so there is a high probability that you won't hang you." Xu Qiu said: "However, his class is not easy to choose, you are also lucky."

　　 "I didn't choose it, but I went to him and asked him to add my student ID in the backstage of the course selection system." Ren Bin said.

　　Madu University’s course selection is divided into three rounds.

　　The first round is the pre-selection at the end of the semester. Students choose the courses they want to take, but they cannot choose multiple courses at the same time.

　　 After the first round, the number of students reported for some courses will exceed the maximum number.

　　 For example, a certain course is limited to 50 students, and 150 people are reported. Then 50 people are randomly selected from the 150 people, and the other 100 people will be dropped out.

　　 The second round is two weeks before the start of the semester. Students choose courses based on their dismissal status. At this time, they can only choose courses that are not full.

　　 The third round is two weeks after the beginning of the semester. Students can choose to withdraw and choose courses according to the course audition situation, and they can only choose courses that are not full.

At the same time, the elective restrictions for all courses have been lifted. In the first two rounds, some professional courses will be protected. For example, the professional courses of the materials department can only be selected by students from the materials department. However, as long as there is a margin in the third round, all students Can be selected.

　　 In addition, the teacher of each course has the authority to increase the number of courses in the background, so if you don’t choose a class, you can report your student number to the teacher and let him add it in the background. Most teachers will not refuse such a request.

　　 "If I remember correctly, mathematical analysis should be a 5-credit course, and it will cost 650 yuan to retake it," Xu Qiu said, "How about it, doesn't it hurt?"

　　 "It's okay, we retake 130 yuan for a credit, but 500 yuan for foreign students," Ren Bin said: "Don't talk about me, how are you doing in scientific research now, I think you come back late every day recently."

　　 "Our group mainly makes solar cells. Now the basic preparation process has been learned, and the boss has just arranged a project for me to do it." Xu Qiu said.

　　 "Yes, it has only been two weeks since I took over the project. When I post an article, please treat me." Ren Bin said.

　　 "It's a small project in school, for fun." Xu Qiuqian said.

　　 "By the way, the counselor sent an e-mail to inform us of the time and classroom for the course examination in our department." Ren Bin said.

　　 "Okay, then I'll go take a look." Xu Qiu said.

　　 Xu Qiu returned to his desk, took out the computer, and opened the mailbox.

　　 Inbox (1454).

　　 I haven't checked my mailbox for several days, and I have received a lot of spam.

　　 There is an email subject that is interesting:

　　 doesn't even have a poisonous accessory, so I just bludgeon it. There is no fool to believe it.

　　 Xu Qiu shook his head, permanently deleted the mail, and then began to organize his mailbox.

　　 The e-mail from the instructor only informs about the examination status of the course of the material department, and you need to find the courses of other faculties by yourself. Usually, the instructor will communicate it by mail, classroom dictation, and courseware annotations.

　　 Xu Qiu sorted out the examination time of the courses taken this semester.

　　 There are six courses in total, "Material Preparation and Processing", "Material Analysis", "Composite Materials", "Inorganic Functional Materials", "Modern History Outline", "The Spirit of Law". UU reading www.uukanshu. com

　　 "Material Preparation and Processing" and "Material Analysis" are degree professional courses, which are arranged in the last two weeks of the exam week, exactly one in a week, both of which are closed-book exams.

　　 Both courses are courses that require a lot of memorization and recitation. Fortunately, their test interval is about one week, and the review time is sufficient. It is not a big problem to guarantee B+A.

　　 "Composite Materials" and "Inorganic Functional Materials" are professional elective courses, which are arranged in the first two weeks of the examination week, and they are in the form of open-book examination and report.

　　 "Composite Materials" is said to have a lot of questions. Although it is an open-book test, more than half of the people can't finish it. However, Xu Qiu is very confident in his hand speed. It should be no problem to get an A.

　　 "Inorganic Functional Materials" is said to be divided according to the number of PPT pages. Xu Qiu once doubted the authenticity of the rumors, but he would rather believe it than others. In order to get A, you still have to prepare the PPT carefully.

　　 "The Outline of Modern History", the closed-book exam, you can only memorize it hard. It is a bit too difficult to compete with liberal arts students for A in this course, and you can only fight for B or B+.

　　 "The Spirit of the Law" is an elective course for general education, an open-book exam, you only need to read this book through once, and there is basically no problem. It is also guaranteed to be B and B+.

　　 After planning the review plan for the exam week, Xu Qiu lay on the bed and entered the system space.

　　When he came to the simulation laboratory, Xu Qiu found that the 216 rooms copied by the system were no different from the real ones, but they could only copy things related to the experiment.

　　 Isn’t the senior sister also related to the experiment, why didn’t it copy it?

　　 If you copy it, you can...

　　 asked her to help with the experiment.

　　 Work efficiency doubles instantly.

such a pity.
