A couple of questions about Environmental Science.

<p>Hey, does anyone know of a website that has reference on every type of math equation that's likely to appear on the exam?</p>

<p>Also, is Barron's enough for self-study, or should I supplement it with a textbook? I know Smartypants is good, but is it enough to get at least a four?</p>

<p>BUMP.</p>

<p>Anyone?</p>
