content: I used this book in a TOEFL preparation course for about a month and found it a bit disappointing. The book's explanations are quite technical (which is sometimes helpful, especially in the grammar section) but my intermediate-level students all found the practice exercises in the book too easy. The CD-ROM practice tests, on the other hand, were too hard. Some of the Writing section's explanations were good--especially with thesis statements and conclusions--but the Reading section was ridiculously banal. In addition, there aren't enough practice tests, especially in comparison with other TOEFL study materials available on the market. For the price you're paying, you'd be better off buying Longman's Complete Preparation (for intermediate to advanced students), Longman's Introductory Preparation (for beginner students), or Barron's TOEFL book with 8 practice tests.
