Kaplan 2400 Book

<p>I got recommended to one of these but I don't know which to buy: the 2007 edition or the 2006</p>

<p>For some reason the 2007 edition is about $7 cheaper o.O - anyone know why?</p>

<p>I'm planning to get them from amazon:

<p>bumppppppppp</p>

<p>I used it for the March SAT 07' and I got the 2007 edition, it's best to have the most updated material. in addition, this book rocked because it showed you all the hardest stuff you would encounter.</p>

<p>personally i think the barrons 2400 is better. It really improved my math and i rarely touched it and it has good CR techniques especially for passages.</p>
