This book has a dual purpose: to enable teachers to become informed about the content of the exams and to prepare candidates for the French language diploma examination, DALF level C1, organized by the CIEP. The DALF level C1 is usually obtained after 700 - 800+ hours of instruction. For this purpose, twelve folders + corrections + 2 CDs with methodological guidelines are proposed to fully understand the exams (written and oral) and all their corrections (composition + reasoned essay + presentation). The two written exams (composition + reasoned essay) + the oral exam (presentation) are presented in the form of authentic audio documents that are integrated into a real context and simulate the execution of oral production (12 folders / additional CD).
