The Student's Book provides approximately 80 hours of core teaching material, which can be extended to 120 hours using the photocopiable resources and extra ideas in the Teacher's Book. An interactive CD-ROM, which comes with the Student's Book, encourages learner autonomy with exercises in all language areas, video, games, customisable tests and a progress chart. At Advanced level, 'Accurate Writing' sections help students overcome typical problems such as spelling and punctuation. 'Real World' lessons help learners become more spontaneous, natural communicators by teaching practical language as well as further developing learners' reading, writing, listening and speaking skills.
