Interchange Third Edition is a 4-level series for adult and young adult learners of English from the beginning to the high-intermediate level.

Student's Book A contains units 1-8, the first half of the full Student's Book, along with frequent Progress Checks that allow students to assess and monitor their own learning, and a self-study section. Included is a Student Audio CD that contains the Conversation, Pronunciation, and self-study section from the Student's Book. As with the other levels of Interchange Third Edition, a complete set of ancillaries is available to make classes productive, varied, and fun.Richards, Jack C. is the author of 'Interchange Student', published 2005 under ISBN 9780521602204 and ISBN 0521602203.
