Kaplan and Princeton update their GMAT books for 2007
I don't have any reviews for these books. The only thing that I can say is that the Princeton DVD version seems interesting as this is the first time any of these two companies have released anything other than a CD with their books. If you have any feedback on these, please post them here.
By the way, Kaplan is generally the better set of books and have harder questions. The Quant Math review in the Kaplan books is superior to that of the Princeton one as well. The difference between the 2005 and 2006 books for both companies was nothing more than an addition of more questions for the practice stuff. Would you believe that they didn't change even a word of the study guide sections from 2005 to 2006. Let's hope these 2007 books are better than that.
