The Open World Preliminary offers a unique approach to language management, combining exam preparation with real-life language situations. Each unit of the Student's Book explores different topics, allowing students to build their confidence as they acquire the language and skills needed for everyday situations in English, as well as for exams.

The Workbook reinforces and expands the language and exam skills covered in the Student's Book and includes audio files for the listening activities. An Online Workbook is also available separately, along with classroom audio material that includes the listening resources from the Student's Book in the Teacher's Book.
