I Have a Research Support System

Returning to the dormitory after taking a shower, Xu Qiu saw Ren Bin sitting at the computer desk, wearing earphones, and operating the laptop with the touchpad.

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 earphones.

Review? Xu Qiu asked.

I'm not reviewing, I'm previewing. Ren Bin said with a sad face: These professional courses are too difficult.

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

I haven't passed Mathematical Analysis, Physical Chemistry, and C Programming yet. This semester, I quickly retake one, otherwise I'm afraid the department won't let me graduate. Ren Bin scratched his head and said.

Mathematical analysis is to do more questions, such as Ji... Xu Qiu originally planned to recommend Jimedovich to him, but after thinking about it, it seemed that it was not suitable for him, so he asked: Which college did you choose as a teacher? From the School of Mathematics, or from the School of Computer Science? Teachers from the School of Science and Technology are better for the branch.

Mr. Zhang Wei should be selected from the School of Economics and Design. Ren Bin said.

Ms. Zhang Wei is notorious for giving good grades. When you take the final exam, fill in the test paper and don't leave blanks. Zhang Wei sees that you are a third-year student, so there is a high probability that you will not be rejected. Xu Qiu said: However, his class is not easy to choose, and you are also lucky.

I wasn't selected at first, but I went to him and asked him to add my student number in the background of the course selection system. Ren Bin said.

There are three rounds of course selection in Shanghai Comprehensive University.

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 more than one course at the same time.

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

For example, if a course is limited to 50 students, and 150 students sign up, then 50 students will be randomly selected from the 150 students, and the other 100 students will be withdrawn from the class.

The second round is two weeks before the start of the school year. Students can choose courses according to the circumstances of their being withdrawn. At this time, they can only choose courses that have not been fully selected.

The third round is two weeks after the start of the semester. Students can choose to withdraw or choose courses according to the course trial situation. Similarly, they can only choose courses that are not fully selected.

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

In addition, the teacher of each course has the authority to increase the number of students enrolled in the background, so if you can’t choose a class, you can report your student number to the teacher and ask him to 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, Xu Qiu said, How about it, does it bother you?

It's okay, we retake one credit for 130 yuan, and foreign students pay 500 yuan for one credit, Ren Bin said, Let's not talk about me, how are you doing in scientific research now, I see you come back late every day recently.

Our group mainly makes solar cells. Now that we have learned the basic preparation process, the boss just arranged a project for me to do. Xu Qiu said.

Okay, it's only been two weeks, and I've taken over the project. When did you publish the article, you want to treat me. Ren Bin said.

It's just a small school project, just for fun. Xu Qiu said modestly.

By the way, the counselor sent an email, informing us of the time and classroom of the department's course exams. Ren Bin said.

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

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

Inbox (1454).

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

There is an email title that is a bit interesting:

Your device has been temporarily locked

Xu Qiu clicked on the title to view the text.

There is not even a poisonous attachment, just empty words, there will be no fools who really believe it.

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

The counselor’s email only notifies the exam status of the materials department courses, and the courses of other departments need to be found by themselves. Usually, the lecturer will convey it by email, classroom dictation, courseware annotation, etc.

Xu Qiu sorted out the exam time for the courses he took this semester.

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

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 a week, and both are closed-book exams.

Both of these courses require a lot of memorization and recitation. Fortunately, the interval between their exams is about one week, and there is plenty of review time. It is not a big problem to keep B+A.

Composite Materials and Inorganic Functional Materials are professional elective courses, which are arranged in the first two weeks of the exam week, in the form of open-book exams and reports respectively.

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

Inorganic Functional Materials is said to be graded according to the number of PPT pages. Xu Qiu once doubted the authenticity of this rumor, but he would rather believe it than believe it. In order to get an A, he still has to prepare the PPT seriously.

Outline of Modern History, a closed-book exam, can only be memorized. It is a bit too difficult to compete with liberal arts students for an A in this course, and you can only strive for B or B+.

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

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

When he came to the simulation laboratory, Xu Qiu found that the room 216 replicated by the system was the same as the real one, but only things related to the experiment could be replicated.

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

If you copy it, you can...

Let her help with the experiment.

Work efficiency doubled instantly.

such a pity.
