The reason many students find economics difficult is not because they don't know the content, but because they don't organize it properly.
If you organize the content of economics well with consistent logic and framework, you will be able to understand a lot of economics.
This book was created to address the difficulties faced by such students and to facilitate efficient learning for students studying economics through my lectures.
I hope this book will help you get to your destination a little faster.


If you find anything inconvenient, lacking, or praiseworthy while studying this book, I am always waiting to hear your feedback via email (sonconomics@gmail.com).
We will fill in what we lack and further develop what we excel at, creating books and lectures that will satisfy many test-takers.


I would like to express my gratitude to everyone at Sam & Books who helped me create this book, as well as to everyone at Namu Management Academy and Seoul Law School who always provide assistance with my lectures.
