Quick Suggestions for Environmental & Chemistry supplement

<p>Can any1 give me a suggestion for AP environmental self study because ive gotten mixed answers and reviews. Pros/Cons or explanations of why you reccomend it over a different book!</p>

<p>side note: can any1 reccomend a good book to supplement an honors chemistry class? would the SAT II book from a company be good enough?</p>

<p>Thanks</p>
