People at the practical education center only want to drop out.

It's not actually that bad.

how to say?

Bai Lan pulled her pants tighter; sitting for a long time made the fabric of the pants feel uncomfortable against her skin.

Then, he thought to himself:

General~

Although Ichinose has finally decided to spend money on desserts, she still won't spend too much money on pleasure.

Therefore, the dessert shop she chose was just an ordinary dessert shop, at most a better one among ordinary ones, or rather, one that suited her taste. It didn't sell anything particularly high-end.

Most ordinary sweets are like this: they taste delicious in a few bites, but become cloying after a few more.

Or perhaps it was because Ichinose's expression was too "exaggerated" when recommending these things that Bai Lan had too high expectations for them. The huge contrast made Bai Lan somewhat disappointed with these desserts, and she felt a bit cheated.

Although Bai Lan didn't think Ichinose was lying, it was probably just a matter of personal taste.

Bai Lan understood the reasoning, but her emotions, combined with the fact that she had eaten too much sweets, caused her to gradually lose her appetite.

Then, Bai Lan thought to herself: I've eaten so much already, Ichinose should have eaten enough too, right?

After all, it's said that girls' appetites are like a cat's belly in front of boys; no matter how much they can eat, they will subconsciously restrain themselves and not eat too much.

If you've eaten enough, then pack up and leave.

Thinking of this, Shiro turned her gaze away from the dessert and looked up at Ichinose.

Then, Bai Lan saw a chubby face with two crescent moons and a few white clouds.

Ichinose-san?!

Ichinose - Archangel - Perfect Idol - Elegant and Serene - Gentle and Refined - Honami, your image has collapsed, do you know that?!

With that thought in mind, Bai Lan couldn't help but take out her phone and take a picture of her chubby face.

Well, this video will come in handy when Ichinose brings up his "etiquette" again in the future.

Bai Lan only took pictures for about ten seconds, and before Ichinose could react, he snapped a few more photos.

However, Bai Lan overlooked one thing.

In Japan, various devices with camera functions automatically activate the flash and sound effects when taking a picture.

Moreover, the flash and sound effects are particularly noticeable to prevent people from taking photos secretly.

However, Bai Lan overlooked this point for a moment.

After he pressed the shutter button several times, Bai Lan's phone immediately made several clear "click" sounds and flashed white light several times at Ichinose's face.

The blinding white light pierced through Ichinose's squinting eyes, immediately drawing her attention.

Ichinose subconsciously opened her eyes, which she had been squinting, and looked in the direction of the blinding white light. Then, she saw Shirai holding her phone and pointing the camera at her.

"What are you doing?" Ichinose asked instinctively.

Bai Lan subconsciously said, "Collect dirt on me."

"Huh?" Ichinose asked in confusion.

Bai Lan quickly changed her words: "To record beautiful moments."

"Let me see," Ichinose said, extending her hand.

Bai Lan thought for a moment, then turned her phone screen towards Ichinose.

Looking at the chubby-faced girl on the screen with cream smeared on her face and a silly grin, Ichinose blushed instantly.

Ichinose grabbed a tissue to wipe his face with one hand and reached for Shirai's phone with the other.

"Delete it!"

Ichinose cried out, both embarrassed and annoyed.

Oh dear~ the gentle archangel is angry!

Bai Lan suddenly realized that he might have really gone too far. He quickly raised his hands in surrender and said "Okay, okay" while operating his phone.

The next moment, Ichinose felt a vibration in her pocket.

I took out my cell phone and took a look.

An email from Bai Lan?

Open the email.

Then, she saw that familiar yet unfamiliar chubby face, and it was moving!

Ichinose said, "Shiro-kun, you..."

Before Ichinose could finish speaking, Shirai said again:

"Okay, okay, I've already deleted it. To be honest, I think what you did just now was much funnier than usual. I suggest you save it."

After speaking, Bai Lan put away her phone and, as if nothing had happened, resumed eating.

Even though she had already eaten enough, Ichinose's appearance just now was so appetizing that it suddenly gave Shiraishi a renewed appetite.

Is this what they mean by "beauty is food for the eyes"?

"Did he really delete it?" Ichinose asked with some doubt.

But after Ichinose calmed down and thought about it carefully, she felt that it didn't really matter even if it wasn't deleted. Shirai probably wasn't the kind of person who liked to use other people's "ugly photos" to play pranks... right?

Seeing how much Shiraisha was enjoying her food, Ichinose gritted her teeth and continued eating as well.

121. Insurance and Accidents

Ⅲ Righteousness and hegemony, clothing and so on, also three uncles

Time flies and three days have passed.

Over the course of three days, everyone in the class handed in their scores from the three self-tests to Bai Lan.

Fortunately, no one did anything reckless, falsely reporting achievements beyond their capabilities and adding unnecessary workload for Bai Lan.

In this way, the first phase of Bai Lan's plan for the original Class D to prepare for the midterm exams has been completed.

After collecting everyone's self-test scores, Bai Lan used the data to determine each person's learning level and stability, and planned the target score range for each student in the midterm exam that evening.

Based on the three self-test scores provided by the class for each subject, Bai Lan found the lowest score in each subject.

Multiply this lowest score by 2, then subtract 20% of the result. The final value is the "highest average score" that can ensure no student drops out.

If Bai Lan sets the class average score higher than this "maximum average score", there is a high probability that some students will fail as a result.

The lowest score is multiplied by 2 so that the lowest score can reach half of the average score, which is a passing grade.

The reason for reducing by 20% is that 20% of the questions in the last quiz were beyond the syllabus, while the test papers used for self-testing in the class were normal test papers.

Therefore, for students who are learning normally, the maximum score they can get is not 100 points, but only 80 points.

Those who score 80 or above have basically studied extra material outside the textbook on their own.

Therefore, the score obtained from the self-test using a regular test paper needs to be reduced by 20% to get the estimated score for the midterm exam.

As long as Bai Lan keeps the class average score below the "highest average score", there will basically be no failing grades in the class.

However, the average score should not be kept too low.

Because the lower the average score, the fewer questions can be answered in order to control the score.

The fewer questions there are, the higher the percentage of marks each question carries.

With a very limited number of questions available, even a single mistake could lead to failing the exam, making the margin for error very low.

In Bai Lan's view, the ideal margin of error is that everyone can still pass if they get about three questions wrong when controlling their score.

Each question is worth approximately 2 to 5 points.

Therefore, the failing score should ideally be about 10 points lower than the lowest score, and the "target average score" is the lowest score minus 10 and then multiplied by two.

As long as the minimum score reaches 20 points or above.

After that, Bai Lan only needs to arrange things like this:

For those whose lowest self-test score is below the "target average score", Bai Lan's task is to perform to the best of their ability and guess a few more multiple-choice questions to avoid mistakes and keep themselves away from failing scores.

For those whose scores are usually slightly higher than average, they should just perform as they did in the self-test, only answering questions they know how to answer and avoiding guessing, which would introduce unpredictability.

For those whose average scores are significantly higher than average, but who do not reach 90 points or above, encourage them to lower their scores slightly to get as close to the average as possible.

In this way, the class's "target average score" can be controlled at a value with the highest tolerance for error.

In addition, the higher the "target average score", the more room Bai Lan can leave for top students who are confident of getting scores above 90, allowing them to win more awards for the class.

After all, if the "target average score" is too low, top students will not be able to perform well. In this case, a score of 90 will raise the class average by more than two points, and these two points are very likely to cause those who only score a dozen or even a few points to fail.

Conversely, if the "target average score" is high enough, a score of 90 can only raise the average score by less than one point, and its impact can be basically ignored.

Unfortunately, however...

Although Hirata organized a study session some time ago, some subjects cannot be improved by short-term efforts.

With Bai Lan forbidding guessing and only allowing students to answer questions they were confident about, let alone 30 points, many students even got 0 points in subjects like English and Math, which require long-term accumulation!

Goodness, their scores are usually based on the "probability" of multiple-choice questions.

This would result in a very low margin for error.

However, Bai Lan was not without options.

It's important to know that in Japanese high school exams, multiple-choice questions make up a significant portion of the score for math and English!

In these two subjects, nearly half of the marks in mathematics come from multiple-choice questions, while in English, multiple-choice questions account for nearly 80% of the marks!

Bai Lan's solution to this situation was to have everyone fill in the same option for all multiple-choice questions, while leaving all other questions blank.

Because everyone chooses the same option, in the end, everyone will get the same score, which will be approximately 25% of the total score for the multiple-choice questions.

At the same time, this score of around 25% is also the class average, while the failing score is half of the total score for multiple-choice questions, which is 12.5%.

The gap between 12.5% ​​and the lowest score of 25% can be used as room for top students to perform.

Top students can predict other people's scores by knowing their choices, and then play accordingly.

Don't be fooled by the fact that there's only a 12.5% ​​difference between 12.5% ​​and 25%.
