The series "Greek" is aimed at those who are learning the Greek language as a foreign language and/or preparing for the Greek language proficiency exams of the Center for the Greek Language (CGL), the Institute for Lifelong Education of Adults (ILEA), university teaching centers, or other institutions that conduct or may conduct similar exams. The books are primarily written for classroom teaching. However, they can also be used for self-study with the help of a good (bilingual) illustrated Greek dictionary.

The third book in the series, Greek C, corresponds to level B2 of the CGL. Like the previous books in the series (Greek A and Greek B), which quickly emerged among the most popular Greek teaching manuals in Greece and abroad, this book contains rich illustrations, written and oral exercises of all kinds (phonological, grammatical, syntactical, text comprehension, etc.), as well as an audio CD with dialogues and listening exercises. The units of this book have been tested for several years in adult preparation classes and introduce students to the reality of contemporary Greek language and society.
