What is the difference between these two books ?

<p>[Amazon.com:</a> Barron’s SAT 2400: Aiming for the Perfect Score (Barron’s Sat 2400): Linda Carnevale M.A., Roselyn Teukolsky M.S.: Books](<a href=“http://www.amazon.com/Barrons-SAT-2400-Aiming-Perfect/dp/0764138057/ref=pd_sbs_b_5]Amazon.com:”>http://www.amazon.com/Barrons-SAT-2400-Aiming-Perfect/dp/0764138057/ref=pd_sbs_b_5)</p>

<p>and</p>

<p><a href=“http://www.amazon.com/Barrons-SAT-2400-Aiming-Perfect/dp/0764132695/ref=pd_sim_b_img_1[/url]”>http://www.amazon.com/Barrons-SAT-2400-Aiming-Perfect/dp/0764132695/ref=pd_sim_b_img_1&lt;/a&gt;&lt;/p&gt;

<p>The first has 384 pages,the second 379 i think.And the covers are not the same.Both books are ;Barron`s 2400</p>

<p>the red one is the newer version. in all respects though its going to be practically the same thing.</p>

<p>I see.Well,i think amazon must remove the old version of the book.</p>
