What are the Best Prep Books for Environmental Sci?

<p>I’m not planning to spend a hundred dollars on an actual textbook but I am willing to look into self-study review booklets from major publishers. What books did you use for this exam? Is REA ok?</p>

<p>I have the same question… any suggestions? I’ve heard the smartypants guide is good, but are any of the mainstream publishers worth buying? (pr, barrons, rea, etc.)</p>
