The Student's Book includes 16 small chapters divided into 8 thematic units. The 1st volume leads to level A1 and prepares for the Fit in Deutsch 1 exam. Planet is the first teaching method exclusively for Greek students. It is aimed at beginner students from 11 years old and leads through three volumes to level B1 of the Common European Framework of Reference. It prepares for the Fit in Deutsch 1 (level A1), Fit in Deutsch 2 (level A2) exams, and the Goethe-Zertifikat B1 (Zertifikat Deutsch and Zertifikat Deutsch für Jugendliche) and offers a pedagogically complete proposal for the lesson. The series is distinguished by its clear structure: every two chapters form a thematic unit and tell a story. This keeps the student's interest undiminished. Central roles are played by the skills of understanding listening and written texts and producing written and spoken language. A new element for the Greek student is the mediation practiced based on situations from Greek daily life. Additionally, the series offers students the necessary vocabulary to express their experiences and interests. The "Zum Schluss" section at the end of each thematic unit offers additional texts, techniques for understanding written texts, information about German-speaking countries, suggestions for group projects, tips for more effective study organization, and review exercises. The "Να τι ξέρω!" section includes a concise presentation of grammar, as well as a list of the most important vocabulary and expressions.
