The Advanced Student's Book gives learners an immediate sense of purpose and clear learning objectives. It provides core grammar and vocabulary input alongside a mix of skills. Speaking lessons offer a unique combination of functional language, pronunciation and conversation skills, alongside video filmed in the real world. Each unit ends with a consolidation of core language from the unit and focuses on writing within the context of a highly communicative mixed-skills lesson. Students also have access to the Cambridge Learning Management System, which includes a complete assessment package with extra personalised practice and online workbook.
