This new 11th edition offers complete and up-to date preparation for the Paper-Based TOEFL and the Computer-Based TOEFL, with a preview of the Next Generation TOEFL test. There is extensive practice-even for students who don’t have access to a computer. The manual includes a review chapter for each section of the TOEFL, including the new Speaking Section, and presents nine full-length model tests for the Computer-Based TOEFL, with questions answered and explained, along with one full-length model test for the Next Generation TOEFL and a practice test for the TOEFL Academic Speaking Test (TAST), with example answers. This compact disc-and-book package provides the audio versions for the Listening Comprehension sections of all model tests
