After the morning meeting, Crescent Academy ushered in the first morning self-study since the establishment of the school.

Thirty students sat in the same classroom, and they were still talking, but they fell silent the moment they saw Claire walk into the classroom with a stack of test papers.

The sight of the pin drop also shocked Claire for a moment, and she squeezed out a smile and spoke.

"Don't be nervous, this is just a practice paper, and it won't be registered on your transcript."

Claire's words did not put the students at ease, and the tension became even stronger as the test papers were distributed.

Evanna was not good at magic in the first place, and at this time, she scratched her ears and cheeks in the face of this math problem like a book of heaven, and she didn't know where to start.

"The model for this question seems to have been taught in what class, and what is it?"

She scans through the papers, trying to find the ones she can get her hands on, but soon she realizes that she can't write a single question.

Evanna looked to the side, Xia Luo frowned, as if she was confused about the test paper, but compared to Evina, Xia Luo at least wrote several questions.

The difficulty of this paper is not smooth, nor is it simply in order, it is designed by Reiner to test the students' ability to observe the questions, except for those who have no questions to stump, most of the students with good grades are actually just knowing how to choose.

They are able to see the difficulty of a question and the time it takes to solve it, and they are not obsessed with a perfect score, but only sprint towards an 80% score, which is a simple test-taking strategy, a measure taken to maximize the use of time.

Reiner, a veteran fritter who has been educated for exams for more than ten years on Earth, and a high school teacher, naturally knows the doorway clearly, and he will also tell the students these skills in tonight's lecture, but he wants to see which students can learn without a teacher first.

In the midst of a silent wail, only three people seemed to be indifferent.

One of them was Elimia, who, though sometimes stagnant, managed to do her job well, and from an old family, she must have been very comfortable with magic, and although she was dissatisfied with Reiner's actions, she managed to complete her studies.

There was also a man named Fina. Nabistin, a little girl with short hair and glasses, who has been ranked first in Crescent Academy's final exams for many years and is also the most promising student to advance to a full-fledged mage, it seems that these basic questions will not be difficult for her at all.

And the third person is actually Dana.

Dana looked at the test paper, although she had never seen the questions on it, but many of the question types were familiar to her, and they were the types on the Reiner special test paper that had tormented her for many days, and since she had done it many times, she drew the gourd in the same way, and soon got the answer.

She just followed the steps that Reiner had told her to solve, calculate, and when she came back to her senses, she had already written the last question.

Raising her head, Dana looked at the classmates next to her, almost all of them were still struggling with the sea of questions, with a painful look on their faces, you know, in the past exams, such a situation should have been reversed.

Dana rubbed her eyes to make sure it wasn't her dream, then lowered her head and checked her answer again before continuing to focus on the puzzle she had skipped earlier.

For Evenna, time flies, and she has only written three questions when Claire, who is on the podium, clapps her hands.

"It's time."

"Huh?" "How is it so fast?" "Let me finish the math!" "Wait, don't worry......"

The students' cries came and went, and the air of sadness filled the classroom.

"How did you calculate the third question just now?"

"I remember it was like I had to use a formula......"

After the exam, it was time to hear and answer the answers, and several girls gathered together and chattered like sparrows.

"That angle must be sixty degrees, I figured it out!"

One girl swore that the answer was shared by the others.

Dana heard their discussion and showed a slightly puzzled expression, and was seen by the girl and asked.

"Danna, is your answer to the third question sixty degrees?"

The girl probably just had the idea of asking casually, and didn't expect Dana's answer.

But I didn't expect Dana to think for a moment and blurt out.

"There are two answers to this question, one is sixty degrees and the other is one hundred and twenty degrees, because the value of sinA obtained in the end is three of the root number of twoths, so there are two angles in reverse."

“......”“......”“......”

Dana's answer caused several girls to freeze in place, thinking about it, as if there was nothing wrong with what she said.

That means you've got the wrong answer.

"Well, I've got classes later, I'll go first."

With an apologetic expression, Dana hurriedly packed her things and hurriedly left the classroom.

However, the paper could not hold the fire, Dana's performance in mathematics soon spread, every time after class, there would be students to find Dana, ask her a variety of math problems, although not all of the problems she can solve, but most of them are similar types of problems she has seen, a little thinking can also get a certain idea of how to solve the problem.

At the time of an exam, Dana became what the students called a math master.

It was only then that Dana realized the role of Reiner's math test paper.

It not only exercised her computing ability and ability to solve conventional problems, but more importantly, taught Dana the idea of problem solving, now whenever Dana encounters a problem that she has never seen, she will first list all the known conditions, and then continuously deduce the implicit conditions through the known conditions, and finally analyze the problem and transform it into a problem with a known solution method.

Even if you put it into magic, you can quickly learn and even deepen your understanding by converting a spell model that you have not mastered into a combination of known spell models.

For example, Dana found that there were many similarities between the standard zero-ring spell fireball spell and the standard one-ring spell fireball, and by analyzing the spell model construction, she quickly figured out the differences between the two spells, which greatly helped her master the fireball technique.

This is the effect of inductive summarization.

Originally, Dana felt that for many people who would not become mages in the future, what she was learning now was useless, and being a baroness did not need to learn trigonometry and analytic geometry, nor did she need to know alchemy reactions and the history of magic, but now, Dana understood that the so-called learning is not just about learning knowledge, but more about learning a way to learn.

Thinking of this, Dana couldn't help but be full of gratitude to Reiner, and he didn't use boring preaching, but let Dana actually experience this, which benefited him for life.
