Barron's 2007 ap environmental science, kaplan, smartypants and Miller textbook

<p>Can anybody tell me if Barron's 2007 ap environmental science, kaplan, or smartypants review book is better? Also, is the Miller textbook sufficient enough to help a student get a 5? If it is sufficient, what chapters would I need to read?</p>

<p>Can somebody answer my question?</p>
