While in structure the Workbook mirrors the Students´ Book, it also provides students with an extensive full-colour reference section covering Grammar, Vocabulary, Speaking and Listening, Pronunciation and Self Assessment. The Workbook can be used either in class, to keep fastfinishers or stronger students busy, or as homework. It is ideal for mixed-ability groups as activities are classified with one, two or three stars according to their level of difficulty. It should be possible for all students to complete the one-star activities, while two-star activities are aimed at the average students and three-star activities should be reserved for those students who need an additional challenge. The accompanying MP3 CD contains recordings of all Workbook audio tracks.
