The level B1 Student's book includes 18 units and 6 self-assessment tests. Each unit has 2 sections: presentation of contents and practice.

The presentation of contents parts are made up of the following sections: 

• Authentic and practical examples of the language in use. 
• "Así se habla": a set of expressions that will enable students to practise communicative functions.

"Así es": this provides grammatical explanations.

"Con estas palabras": this provides an overview and visual presentation of the most important vocabulary points.

A grammar summary and transcripts relating to the audio content can be found at the back of the book.

The audio content and answers to all of the exercises can be accessed by visiting www.edelsa.es and clicking on the "Zona estudiante" tab. Students will then need to register their details in order to access the content.
