Which books are the best for self-teaching AP Microeconomics and AP Macroeconomics?

<p>And is it worth it to do this, when applying to the University of Chicago for Economics? My GPA isn't the best, so if I do good in those AP tests could it help my chances? Or should I do AP Calculus BC and AP Statistics? Or is it best if I do all 4?</p>

<p>Do colleges even look at AP tests you took near the end of your senior year? I'm a junior, and as you can tell, not too knowledgeable about all of this. </p>

<p>Thanks!</p>
