<p>I have the old 2005 Official SAT study guide and the 2005 Grammatix guide. These two go together because the problems in that official study guide are explained in the Grammatix guide. I am particularly interested in the CR section.</p>
<p>I'm giving this to my son to use for studying for the CR as well as the new 2010 Blue Book.</p>
<p>Is there any reason NOT to use this old study guide?</p>
