<p>Does anyone else have this book? I notice that for the critical reading there seem to be a good number of mistakes in the answer key (i.e., the explanation part isn't compatible with the key right after the test). The questions also seem more ambiguous...if that's possible? Does anyone else feel this way about the book? How was it for you if/when you used it?</p>
<p>thanks!</p>
<p>for me, this book is one of the best preparation book beside the blue book.
the questions are close to the actual test and the critical reading passages are at same difficulty level… this book also reflects my score very well…
during 11 practices, i scored around 550 for reading 
and in the Jan i scored 540 
however, i agree with you that the answer key seems to be inadequate. the explanation is quite vague and a bit too general</p>
