which ACT test prep book?

<p>i dont know much about the ACT since i live in california and i was planning on taking it after im done with the SAT’s. i just bought the “Barron’s ACT 2007 14th edition” and i was wondering if this is sufficient enough to help me do well on the ACT’s (score of 33 and up)</p>

<p>I didn’t use Barron’s, but the official guide and Cracking the ACT are great.</p>
