"Indeed, that's what you think too..."

Nott Finliri frowned, his gaze shifting back and forth between Justin's magic textbook.

"Hogwarts' math curriculum is a bit... well, too childish, practically elementary school math."

The magical world's lack of emphasis on fundamental natural sciences is nothing new, after all, wizards don't rely on science to live.

In fact, during the last summer vacation, Mrs. Finliri had a heated discussion with Justin about the lack of common sense.

Just like all Muggle family debates about magic, all disputes and questions ultimately failed in the face of the all-powerful answer: "magic."

"Simple? Maybe it's because it's a low-grade textbook? After all, even with the new curriculum reform, different grades are considered..."

Amos Diggory leaned over to look at the magic textbook in Mr. Finliri's hand, a strange expression appearing on his face.

Learning to count, I grew taller, this is an apple, that is a peach...

These seem a bit childish.

But considering that Hogwarts has seven grades, decreasing progressively, it seems that the first and second grades can't directly take too difficult courses.

Taking a look at the other parents, without waiting for them to ask, Mr. Diggory actively opened the magic textbook and showed Cedric's curriculum to Mr. Finliri and the others.

"Well, look, Cedric's fifth-grade math and science class has obviously increased in difficulty. I even heard him complain about this... um, trigono—"

Amos Diggory suddenly stopped halfway, subconsciously looking at the page.

As one of the older students who graduated decades ago, Amos was hearing many of these terms for the first time.

"Trigonometric functions, equation of a circle, permutations and combinations, binomial equations... well, this is barely passable."

Mr. Finliri read a few lines of the fifth-grade math and science titles one by one, nodding noncommittally, his dissatisfied expression slightly easing.

Fifth and sixth grades are equivalent to the age of Eton College graduates, and this teaching content barely matches his somewhat vague memories.

Considering that the magical world only introduced mathematics as a major subject last year, this progress is quite good—when Finliri enters the fifth grade, he should be able to reach the advanced level of Eton College.

"Trigonometric functions are a bit difficult, that's one of the killer problems in MATH, and I had the biggest headache with it back then."

Mr. Finliri shrugged with a smile, saying with nostalgia, while turning his head to look at Benítez.

"By the way, speaking of which, I heard that Miss Kaslana participated in the second-grade curriculum content."

"Didn't she just move the enlightenment textbooks she used in public primary school before enrolling?"

"...Well, Elena—only attended one day of math class."

Benítez scratched his nose, said with a strange expression, while raising his hand to gesture roughly.

"She usually, um, studies by herself... because her mathematics learning progress is slightly, just a little bit... ahead."

If it were any other normal child, Mr. Finliri's guess would be more likely, but Elena is a troublemaker who made the teacher cry on the first day of the exam!

As for the fifth-grade teaching content that Mr. Amos Diggory showed, it seems to be... the questions Elena taught seven or eight-year-olds?

"Childish? On the contrary, I think Miss Kaslana and the Hogwarts faculty made the right decision."

Just then, another man's voice suddenly sounded in the ears of Benítez and others.

Everyone followed the voice and saw a wizard raising his magic textbook and sighing softly.

"Although the math and science textbook final exam for this academic year hasn't been held yet, judging from the usual grades, it seems that these 'simple' courses aren't that simple."

"Perhaps it's okay for your non-magical families, but I looked at Susan's grades this semester, and there are only a few times she got 'Good,' and most of the time she's hovering around the passing line."

Mr. Bones sighed again, looking worriedly at his daughter's math and science class grades displayed on the magic textbook, his voice somewhat low.

"Gentlemen, we are now looking at it from an adult's perspective, is it possible... that many children's foundations are really that weak?"

Are numerical calculations and object classification really that difficult?

Perhaps, after his daughter finishes tidying up later, he should have a good talk with her.

Even if these are brand new courses, even if it's non-magical content, it shouldn't be such a terrible result.

"Usual grades? Oh, there really are some at the back—"

Mr. Finliri was stunned for a moment, and hurriedly turned to the back.

Immediately afterwards, his expression gradually solidified, looking like an approaching rainstorm.

Unlike the all-excellent grades he imagined, Justin Finliri's usual grades seemed... no better than Miss Bones'.

Among the parents, Amos Diggory, who complained about the difficulty of the course, was in the best mood—Cedric's usual grades were mostly 'Good' or above.

And the lower the grade of Hufflepuff students, the worse their usual grades seemed to be.

Especially the second-year students, who have almost become a disaster area...

Although most Hufflepuff parents don't pay so much attention to academic performance, it's at least based on passing.

"Cough, is there a possibility—"

Benítez looked around at the parents who were "itching to start" and tried to ease the atmosphere uneasily.

"Actually, the content of the second grade is the most difficult of all grades... maybe the title just looks..."

"Absolutely impossible."

"No need to say anything, Mr. Benítez."

"These usual grades clearly show a lack of seriousness—"

"Well, it looks like we need to have a good talk..."

Mr. Finliri's face was as dark as water, his finger gently tapping on Justin's fluctuating grades.

In just two years, Justin went from being an excellent student who could attend Eton College to a fool who couldn't even get a perfect score in counting.

As a father, he must find out what happened, whether it's Hogwarts' magic or Justin's attitude towards learning, this problem must be solved anyway.

…………

At the same time, deep in the Hufflepuff student dormitory.

In a luxurious room located at the end of the aisle, with obscure magical runes branded on the door.

"Hannah? What are these books?"

Mrs. Abbott stood up, raising the stack of dusty booklets in her hand.

Just a few minutes ago, they were hidden tightly under the tables, chairs, cabinets, and even the bed.

However, with Mrs. Abbott's "master-level" housekeeping magic, they popped out of various places like little sprites with lives of their own.

"Uh—"

Hannah, who was tidying up the closet, was stunned, obviously not expecting her mother's magic to be so powerful.

But fortunately, most of the real contraband is hidden in Elena's chest.

Most of the things in this bedroom are randomly stuffed miscellaneous items, after all, in a sense, this is actually a four-person dormitory.

You know, house-elves won't help sort and classify things when cleaning, they only ensure the cleanliness of the overall environment and simple cleaning of clothes and bedding.

This is why she begged her mother to come and help tidy up—over time, there are some things that are intentionally or unintentionally stuffed into every corner.

"Oh, these are old textbooks, the first drafts of this year's math and science textbooks. Elena used them when tutoring us last semester."

Hannah glanced at the booklets in her mother's hand, shivering unnaturally, as if remembering something.

"Don't let them get close to me, I'm still a little allergic to them now..."

"Allergic? The math and science... textbook drafts?"

Mrs. Abbott raised her eyebrows slightly and looked down at the booklets in her hand.

On the cover, there was a somewhat abstract little monster drawn, with a delicate and beautiful quote written on it:

《Mathematics—The Most Brilliant Pearl on the Crown of Human Wisdom》

"Oh, I heard you say that you have a math class this year, learning some simple math."

Mrs. Abbott nodded with a chuckle, looking at the booklet in her hand with interest.

Unlike other wizards, she strongly supports Hogwarts' reform, and she doesn't think it's something that Muggles should learn.

As the current landlady of the Leaky Cauldron, she understands too well the importance of these seemingly insignificant abilities in real life. Without a clear mind, they would have to hire greedy goblins to work as bartenders, which would be too costly. Even if Hogwarts didn't offer relevant courses, she would personally tutor Hannah in arithmetic when she got a little older.

As for the "Elena" that Hannah mentioned, Mrs. Abbott couldn't be more familiar with the name, Hannah had been reciting this name in her ear so many times it was driving her crazy.

"Then you have to study hard, I didn't have your current conditions when I was studying—"

Mrs. Abbott touched the booklet in her hand with great emotion, looking at her daughter with a serious face, her tone rarely serious.

"At least, you shouldn't treat textbooks like this—if I had the time, I would even want to go back to Hogwarts and learn math together."

"...No, no, Mom, this math... is really scary."

Hannah subconsciously took a few steps back, as if Mrs. Abbott was holding a book of demons in her hand.

"Scary? It's just simple numbers and calculations, you're just afraid of trouble..."

Mrs. Abbott shook her head helplessly.

Speaking of which, this was the first time she had seen her Hannah being so resistant.

However, she didn't continue nagging Hannah. The more this is the case, the less you can force your child.

Mrs. Abbott always has her own educational tips for this kind of situation.

"How about this, I'll just flip through a few pages, and we'll compare who's better? Same as before, the loser gets a wish."

"Really? Um—okay! Then we have a deal!"

Hannah glanced at her confident mother, hesitated for a few seconds, and nodded seriously, biting her lip.

Although her mother has used this trick to win her too many times, after Elena's special training, she naively felt that she still had a certain chance of winning.

This child...

Is as simple as her father.

Mrs. Abbott lowered her head and smiled as she randomly opened the first page—

Like the textbooks in Flourish and Blotts, there were neat rows of seemingly magical words written there.

[Chapter 1: This is an Apple, That is a Peach!—Everything in the World Can Be Classified]

· Naive Set Theory and Russell's Paradox

· ZFC Axiomatic System

· Cartesian Product and Relation of Sets

·……

[Chapter 2: One, Two, Three!—Learn to Count]

· Cardinality of a Set

· Linear Mapping

· Algebras and Their Properties

……

"Um..."

Mrs. Abbott flipped through a few more pages quickly, and after a moment of silence, closed the book expressionlessly.

"So, you are learning a new type of magic..."

"That is indeed a bit difficult, you have to work hard—let's continue cleaning the dormitory."

…………

Meanwhile, on the other side.

The culprit looked at the complex forking passage ahead, her expression gradually becoming serious.

Um...

She seems to be...

Lost again.
