This book is intended for students aged 12 to 14 who want to prepare for the "Deutsches Sprachdiplom, Stufe I" exam, known as "DSD I". It follows both the official exam format as defined by the Standing Conference of the Ministers of Education and Cultural Affairs of the Länder in the Federal Republic of Germany (KMK) and the proven formula of the "Arena" series: exam preparation with an additional section of grammar and vocabulary exercises.

It includes 10 model tests with a slightly increasing level of difficulty, covering all thematic areas and the four language skills, with topics suitable for the age group the book is aimed at.

The 1st test contains a detailed introduction explaining the exam format and presenting step-by-step methods for solving each part or exercise of the test. In each test, for the productive parts of the exam (written and oral production), four additional pages with practical exercises are provided, systematically addressing both the most important grammatical phenomena and the vocabulary from levels A1 to B1.

The solutions to all exercises are included only in the teacher's edition "Lehrerausgabe".
