<p>Is there an approximate breakdown for the # of questions for a particular time period for the AP US exam? Like for Physics B I know Electricity is about 30-34% and etc.</p>
<p>Is there a breakdown like that for the US like 10% Revolutionary War, 15% Reconstruction etc.?</p>
<p>"Approximately 20 percent of the questions deal with the period through 1789, 45 percent cover 1790 through 1914, and 35 percent cover 1915 to the present including questions on events since 1980.</p>
<p>Within those time periods, 35 percent of the questions are on political institutions, behavior, and public policy; 40 percent are about social and cultural developments; approximately 15 percent of the remaining questions cover diplomacy and international relations; and 10 percent cover economic developments. A substantial number of the social and economic history questions deal with such traditional topics as the impact of legislation on social groups and the economy, or the pressures brought to bear on the political process by social and economic developments. As you’ve learned, historical inquiry is not neatly divided into categories so many questions pertain to more than one area."</p>
