AP Econ - what should I study?

<p>I'm taking both Macro and Micro.
What do you guys think are some important things to study?</p>

<p>My teacher keeps telling us that externalities will be a short free-response (it was the long one last year), and also to study how to correct inflation/recession using combined fiscal and monetary policies.</p>

<p>What are some others?</p>

<p>I would study monopolies. Everything monopolies! It seems like there are always a decent amount of mcs on it and if you know how to graph a monopolistic firm, it could be easy points for the free response.</p>
