“I hope my competitors don’t read this book” - Reader Review
Over 200,000 Reviews! The Study Bible That's Captivating Asian Students

What if someone who doesn't even know how to handle a weapon goes to war? Unless luck is on their side, they're sure to suffer a crushing defeat.
So, what is the most important weapon in the battle of exams? It's the brain.
Memorizing knowledge and concepts, applying various formulas appropriately to problems, and grasping the core of a problem and deriving an answer are all ultimately done by the 'brain'.
However, most test takers are too busy studying and taking tests right in front of them to be interested in learning the rules or usage of their brain.
And if their grades don't improve, they think they didn't put in enough effort and increase their study time, or they give up on studying, thinking they were just born with a bad brain.

However, after the publication of the book “The Optimal Study Brain” by world-renowned brain scientist Yuji Ikegaya in 2011, the perception of test takers changed drastically.
Students who learned how to study using their brains through this book have left comments such as, “I was able to memorize something I couldn’t even after studying for 10 hours, but I finished it in 2 hours.” They have come to realize that it is not the amount of studying that determines grades, but how well you use your brain.
Afterwards, it was published in China and received an explosive response, and the so-called 'Ikegaya study method' became a trend in Asia.
This trend did not end overnight, but continued for over 10 years, as it was not the secret of one individual who was accepted to a prestigious university, but a study method scientifically verified by a brain scientist based on over 100 years of research.
Even in China, the number of reader reviews has exceeded 200,000 in just three years, and vivid reviews are still being posted consistently.


“If you want to get the grades you want, you have to set up your brain properly first!”
Is it because I'm stupid? Or because I lack effort? The answer lies in brain optimization.

Yuji Ikegaya says this in his book:
“Most people's ability to perform is only one-hundredth of their actual ability.
“Because we haven’t discovered the hidden abilities of our brains.” According to him, those who are called geniuses are just people who have a clever memory, and anyone can become a genius if they know how to utilize and optimize their brains.
The secret of those who achieve excellent grades and pass the exam on the first try, even though they study for the same amount of time, lies in the proper use of the brain and the 'optimal brain settings.'
In this book, he persuasively explains the characteristics of the brain and how it is created to have a brain that doesn't forget anything until the test day after seeing it just once, a brain that absorbs knowledge in a short period of time, and a brain that finds a solution to a problem as soon as it sees it.

His study method emphasizes ‘efficiency.’
For students who have a mountain of things to study, there is nothing more important than studying efficiently.
For example, while other textbooks only talk about the importance of review, this book analyzes and conveys the minimum number of review sessions, time, and intervals based on brain science.
Likewise, it explains the study principles that must be followed for effective memorization, learning, and application, in connection with the characteristics of the brain.
Knowing these principles will help you create the most effective study plan while others waste time studying incorrectly.
Additionally, it provides study strategies that only a brain scientist can teach, such as study methods that take into account brain functions that change with age, effective study times for each subject, and methods to enhance learning ability using theta waves and the amygdala.

“There is nothing more tedious and exhausting than effort without results.”
A neuroscientist's secret recipe for achieving your goals in the shortest time possible.

Studying is hard for everyone.
And the biggest reason why studying is difficult is because grades are often not proportional to effort.
Ikegaya Yuji wrote this book in the hope that if students must study anyway, they will at least achieve results commensurate with the time and effort they put into it.
This is because he was a lazy student who not only hated studying during his school days, but also did not memorize the multiplication table.
Rather than wasting time and energy or exhausting myself because I hated studying, the strategies I stuck to in order to somehow get good grades easily and efficiently turned out to be excellent ways to use my 'brain'.
But as I studied like that, I became more interested in studying and I am still living as a scholar.

There is nothing more boring and tiring than effort without results.
If you've lost interest in studying because your grades remain stagnant no matter how hard you try, or if you've lost confidence and even self-esteem after failing exams countless times, I highly recommend this book.
As one reader commented, “I read this because I didn’t want to study, but now I want to study,” it will definitely be a turning point.
