<p>Do we need to know about hyperbolas? I don't think I ever learned about these in school. I'm looking through Barron's and I know that it's way harder/covers way more than the actual test does, but I'm just wondering what I should know and what I don't need to know.... ughh!!!!</p>

<p>Can we put together some equations that we MUST memorize?
i.e., law of cosines? Should we know half-angle/double-angle formulas? What about trig sums and differences? I forgot all my trig!!! I'm freaking out here....</p>

<p>I'm in the same boat...</p>

<p>Cramming is only making me feel more stupid, haha. I'm starting to get really sleepy, too.</p>
