At breakfast the next day, Zhang Xu got his class schedule.

Before school started, when Zhang Xu lived in the Leaky Cauldron Bar, Professor McGonagall went to Diagon Alley to find him once for the class schedule.

In Zhang Xu's room at the Leaky Cauldron Bar, Zhang Xu and Professor McGonagall sat opposite each other in front of the table that Zhang Xu had conjured up with Transfiguration.

"Mr. Zhang, starting next semester, you will be the acting professor of Muggle Studies, and since you will be teaching Muggle Studies while completing your own course, I would like to ask for your opinion when arranging the schedule." Professor McGonagall said.

Seeing that it was a matter of the class schedule, Zhang Xu also had a headache.

The professors at Hogwarts School of Witchcraft and Wizardry are very hard.

Students from Year 3 onwards take at least two courses from Ancient Runic Studies, Conservation of Magical Creatures, Divination, Arithmetic Divination, Herbal Medicine, Defence Against the Dark Arts, Astronomy, History of Magic, and Mathematics in addition to the eight compulsory courses.

Professors of compulsory courses teach seven grades alone, and professors of elective courses teach five grades.

In grades 1 to 5 before the O.W.Ls exams, compulsory courses such as potions and herbology are taught by two houses in each class, so the professors of these two subjects will teach a total of 14 classes in 1 to 5 years and 4 classes in 6th and 7th grades.

Compulsory courses such as Defence Against the Dark Arts and Transfiguration are taught by one academy per class, so the professors of these two courses will teach twenty classes from grades one to five and eight classes from grades six and seven, for a total of twenty-eight classes.

Elective professors don't have much more ease, with two colleges at a time and ten classes from grades three to seven.

Hogwarts School of Witchcraft and Wizardry has four classes a day, two in the morning and two in the afternoon, excluding astronomy classes in the evenings. Each class lasts an hour and a half, with twenty minutes between classes for students to rush to the next class.

Zhang Xu remembered that in "Drama", Hermione had to take three electives at the same time. Aside from a top student like Hermione, if a student took only two electives, and both of those electives were in those three courses, that student would cry.

Thinking of such a situation, Zhang Xu felt that the class schedule was simply a feast of killing brain cells, which was really embarrassing for Professor McGonagall.

"This year's schedule is really difficult to arrange." Zhang Xu thought for a moment and said, "I suggest that the Muggle Studies class be changed to four houses at the same time per class, so that I will only have five classes a week, exactly one class a day from Monday to Friday." ”

Professor McGonagall thought for a moment and replied, "If you think you can teach students from four houses at once, that's okay to agree with. ”

Because there were not many students taking Muggle Studies classes, the number of students from the four houses taking classes together was not very large.

"I wonder how the school will arrange if students have a conflict in the class schedule for their electives?" Zhang Xu asked.

"We will persuade students to take electives that do not conflict with other times." Professor McGonagall replied.

"I've heard that Hermione has taken all of her classes, and I don't think she will give up any of them easily." Zhang Xu said.

"Yes, there are special arrangements for Miss Granger." Every time Professor McGonagall mentioned Hermione, she always had a look of relief.

Professor McGonagall then told Zhang Xu about the time turner. Every professor knows about this, so Zhang Xu can also know.

Zhang Xu stayed away from this time converter, who knows what limitations this time converter has for users. At least Dumbledore wouldn't have been able to use it, otherwise Voldemort would have been killed by Dumbledore.

Zhang Xu read a very good "Harry Potter" fandom in his last life, in which the protagonist and Hermione had a problem using the time turner, and ran to the era of the Dull King, and then Hermione's stock skyrocketed.

Zhang Xu felt that it was enough for him to travel to this world, and if he crossed over again, he couldn't play the infinite stream. If it's a time to travel to the two-dimensional comic harem world, the left hand Hiiragi mirror and the right hand A Zimeow, Followed by a group of twin sisters, classmates, female teachers, childhood sweethearts, daughters, blonde hair, black hair, brown hair, silver hair, long hair, medium long hair, short hair, clear soup, noodles, straight curly hair, ion perm, double ponytail, single ponytail, double braids, single braids, wavy curly hair, sailor suits, suits, uniforms, sportswear, judo clothes, archery suits, nannys, nurses, maids, policewomen, nuns, military secretaries, loli, tsundere girls, cheerleaders, flight attendants, waitresses, black goths, white goths, white goths, cheongsam, sick beautiful girl, white son, radio wave paranoia, dual personality, queen, princess, stockings, garters, women's dress, men's glasses, eye patches, bandages, school swimsuits, one-piece swimsuits, bikini swimsuits, V-shaped swimsuits, string swimsuits, monsters, ghosts, beasts, ears girls…… OK. In case you run to the Cambrian and Triassic periods, it is better to wipe your neck directly.

So Zhang Xu gave up the idea of finding a time turner in the future.

After thinking for a while, Zhang Xu said to McGonagall: "Professor McGonagall, why don't you give me the task of scheduling this class, I will complete it as perfectly as possible." ”

"Are you sure you can do the job?" Out of a sense of responsibility for her work, Professor McGonagall questioned Zhang Xu.

"No problem." Zhang Xu said with certainty, "As long as you give me the roster of students, the list of all elective courses and the arrangement of other courses, I can complete the arrangement of the school's curriculum in one day." ”

Professor McGonagall thought about it, every year the class schedule would give her a headache for several days, and it was not impossible to let Zhang Xu take over, if he didn't arrange it well, he would be busy again.

So Professor McGonagall agreed to Zhang Xu's request, and at the same time took out a thick stack of relevant materials from her handbag and put them in front of Zhang Xu.

After reading all the materials roughly, Zhang Xu took out two black boxes in Professor McGonagall's surprised eyes.

Zhang Xu opened the laptop he just bought last month, connected it to the power bank, and began to write the class scheduling software.

It is not difficult for Zhang Xu to write the class scheduling software, but the trouble is to enter the students' information into the computer.

Zhang Xu, who was immersed in entering students' information, thought that since there is a quill pen for automatic writing, it is possible to make a manipulator that can type automatically, or even an automatic keyboard and mouse set, which should be very good to sell if it can be made.

When the power bank was only 6% left, Zhang Xu finally used the class scheduling software to arrange the most suitable class schedule for Hogwarts this year.

In this class schedule, Zhang Xu ranked his Muggle studies class at the end of each afternoon.

In other course arrangements, we try to avoid course conflicts between students in elective courses, and also take into account the rest time of professors.

In the end, the order of daily classes was optimized for Hermione, so that her liver would not be overwhelmed.

Professor McGonagall, who had learned how to use the mouse, went through all the timetables written by Zhang Xu and found that this timetable was well arranged, and she couldn't find any faults.

After Professor McGonagall agreed, Zhang Xu went to the embassy with a 3.5-inch tray containing the class schedule, printed a class schedule for each student at Hogwarts, and sent it to Professor McGonagall along with the printed expense reimbursement voucher.
