<p>Does anyone know where I can find a site with an overview of the math formulas that we're suppose to know for the MC/Free Response questions?</p>
<p>Much appreciated, thanks.</p>

<p>Try Course-Notes, they have a section for EnvSci with a few formulas. I don’t think you must memorize them though, just be familiar with them. </p>
<p>You’ll probably want to memorize how to find doubling time and some other things (rule of 70).</p>
<p>I think the only formula I remember using was the rule of 70 (doubling time). There might have been more math problems, but no strict formulas. Memorizing exponential and logistic growth functions might be worth it, but I don’t remember needing them.</p>
<p>Isn’t there some type of conversion formula or something with energy that I’m suppose to know? I have a Barron’s book, but I know its near useless since Barron’s overprepares you.</p>
<p>The energy flow is something like only 10% of energy moves up each trophic level, resulting in an energy pyramid, because 90% of energy will go uneaten and returns to the earth… I’m using Barron’s too, and, since i have the time, i have no problem being over prepared :D</p>
