Differences in RocketReview Revolution Editions

<p>I'm planning to purchase the RocketReview Revolution book from Amazon soon, but I don't know if the 2006-2007 edition is any better than this first edition:</p>

<p>Amazon.com:</a> The RocketReview Revolution: The Ultimate Guide to the New SAT: Adam Robinson: Books</p>

<p>After reading CC, I would be using the book for solely writing/CR strategies. Does anyone know if any changes were made to the first edition in the 2006-2007 edition so I can know which one I should purchase? Thanks for your help!</p>

<p>Buuuuuump.</p>
