The essential grammar points required for the internal exam are explained step-by-step in an easy-to-understand manner, and in addition to the core grammar points, advanced grammar points and points that students should pay special attention to are organized.
We have made it possible to thoroughly organize the grammar learned in each unit through various types of subjective questions, and we have made it possible to organize the content learned in each chapter once again through integrated problem types.

To prepare for the latest professor evaluation methods, a separate descriptive evaluation corner has been created, and the Workbook (for descriptive preparation) provides ample practice of key grammar points through a variety of descriptive questions.
Breaking away from the difficult and complex explanations of the past, we have provided concise and accurate explanations so that you can summarize the key grammar at a glance just by looking at the commentary.
