Self-Studying AP US Government

How hard would it be to self-study AP US Government if I have 4 other AP Courses right now and I start immediately during Winter Break? Also, what is the difference in the level of difficulty between AP US Gov and AP Comparative Gov.</p>

use Princeton review, i basically studied that and got a5
shouldnt be that hard</p>

What about 5 Stepts to a 5 and Petersen’s? I got these from my cousin but they’re from 2006.</p>

Read them and then take practice tests; if you cannot pass the practice tests, get a new book. It is, more than likely, enough, although they aren’t the recommended ones.</p>
