Although this edition is a significant improvement from the 2003 edition it offers very little in the line of new strategy for attacking the games. It does, however, provide more practice questions that are actually former LSAT questions. These, in combination with the answer explanation pages, make the bulk of the advertised extended edition.
This book has been a great introduction to the games section for me, but sometimes the author's LSAT rhetoric is not only boring but virtually useless. The strategy is good, but the enforced suggestion to memorize all his cleverly trademarked names for different question types is over the top. Read this book but do not be too concerned with the trademarked names. Practice the questions and use the strategy suggested. The author does have an easily understandable and, in my opinion, powerful diagramming system which has made the foreign land of logic games more easily solved for me.
Worth the cash over the 2003 torrent pdf I read and will most likely be an easy resell since no book stores in my area carry it.
