Language in Use is a popular and highly acclaimed four-level course which both interests and stretches learners. Each of the four levels comprises about 80 hours of class work, with additional time for the self-study work. The Teacher's Book contains all the pages from the Classroom Book, with interleaved teaching notes, offering not only detailed support and guidance, but also many optional activities to cater for different abilities. There is a video to accompany the Beginner, Pre-Intermediate and Intermediate levels.
