[Machine Translation] This book is a textbook and does not include any CDs, answers, translations, or other accessories. This book is designed for those who are learning German for the first time, and covers grammar up to the level of German Proficiency Test Level 3. It has been revised to make it even easier to use. Some of the "Exercises" and "Readings" have been rewritten to make them more natural in German, and the "Grammar Appendix" has been further enhanced. In addition, a new "Supplemental Exercises" has been prepared for each section of the book.
