Today my class did the first section of Practice TOEFL 6 from this book. In the first 30 questions, there were at least
4 typographical errors. Then we discovered that the answer key
in the back didn't match the test. I have been frustrated with this book in the past because of weak or inaccurate grammar explanations, but this was ridiculous. I really like the idea of a strategy-based TOEFL text, but this book seems like it would be more confusing than helpful.
