Which AP course should I self-study for?

<p>Environmental Science
Microeconomics
Macroeconomics</p>

<p>I can only choose 2 out of these 3, so which two are the easiest to self-study and get a 5?
Thanks so much!</p>

<p>*BTW, is getting the AP National Scholar impressive on college applications?</p>
