What books should I get if I'm not taking a class for these tests?

<p>I’m planning on taking six AP tests for which I’m not taking a class for, and for which I know almost nothing about. From my experience, there are some AP study books that are great for introducing yourself to the material and studying for the test overall, and there are books that are good only for reviewing things you’ve already learned in school. What books should I look into for the following courses I’m not taking classes for?</p>

<p>Macroeconomics
Microeconomics
English Literature and Composition
US Government & Politics
Comparative Government & Politics
Computer Science</p>

<p>same problem here.</p>

<p>US government and politics: Princeton review</p>

<p>Would the Princeton Review be good for any other subjects?</p>
