The book offers eight learning paths, each composed of three units, which are further divided into six lessons. Each lesson is a learning unit lasting an hour and a half. Within each unit, there is material available for at least five hours of work. Each learning cycle forms a self-contained module that concludes with a test. At the end of the volume, there is a grammar reference section and an appendix with materials (such as photos, texts, and diagrams) for use in specific lessons.
