<p>I have Barron<code>s ,PR,BB and Gruber</code>s prep book.I have also purchased the official college board study guide.SHould i only do CB practice tests only ?</p>
<p>on CB are the reals ones</p>
<p>So there it is pointless to take other practice tests except CB`s ones ?</p>
<p>I'd try to stay away from other CR practices. Do Gruber's math and Barron's writing.</p>
<p>and what if all of BB's CR is done?)</p>
<p>then you should buy the official online study guide and the qotd 2009 calendar</p>
