▶ Concept organization according to the Ministry of Education's new curriculum!
In line with the new curriculum's basic direction of fostering fundamental scientific literacy by presenting core concepts and principles, we have explained the core concepts of each subject in a way that makes them easy and quick to understand.

▶ Clear learning objectives!
At the beginning of each part, learning objectives are included in a short story format so that you can know the core topic of each part in advance and focus on it.

▶ Detailed explanations that are easy to understand!
It covers the overall content of each subject, so that it can be used as a supplementary textbook, reference book, or homeschooling textbook, while organizing the explanations as easily as possible. It also includes plenty of related figures and photos to help you understand them more clearly.

▶ Organized so you can see key concepts at a glance!
At the end of each unit, we summarize key concepts with “Know This.”

▶ Solve problems considering descriptive evaluation!
We have included actual descriptive questions to help you become familiar with the process assessment and descriptive assessment that are emphasized in recent curricula.
