AP US Government: Review Books?

So I took AP US Gov’t last semester and so I have a whole semester between then and when I take the actual AP Exam. Does anyone have any recs for any review books?</p>

Princeton Review is the best (which I am using and according to many with experience). Good luck.</p>

AMSCO, bar none, is the best. Read and highlight/annotate the entire book, and you should be good to go.</p>
