My oldest daughter used the 2009 version and it was very helpful for her. So we bought the new edition for her younger sister. But the 2009 edition allowed my oldest to score her practice tests online, which she found very convenient and helpful. This 2011 edition does not have that option. You can still check your scores manually. The important thing, of course, is to actually use the book, practice a lot, and carefully review what you got wrong. In the essentials we expect this book to be useful, just not as convenient as the older edition.
