An invaluable test preparation book, the Testbuch corresponds in form to the "Deutsch als Fremdsprache in der Wirtschaft" created by the German-French Industrie- und Handelskammer. The tests measure competence in the areas of specialized vocabulary, written expresseion, grammar, and reading and listening comprehension, all within the business context. They allow students to work on each skill independently. The test preparation booklet may be used concurrently with any text, or independently as a final preparation before the test. Components include a test booklet and audio material on either cassette or CD. Written entirely in German.
