About AP World History: Modern

AP World History: Modern covers roughly 800 years of human history — from 1200 CE to the present day. The course traces the major political, economic, social, and cultural developments that shaped the modern world: the rise and fall of empires, the explosion of global trade networks, the political revolutions that birthed modern nation-states, and the wars and ideologies that defined the 20th and 21st centuries.

The College Board organizes the content into 9 units, each weighted differently on the exam. Units 3, 4, 5, 6, and 8 are the most heavily tested (12–15% each), while Units 1, 2, 7, and 9 are slightly lighter (8–10% each). The exam itself includes multiple-choice questions, short-answer questions (SAQs), a document-based question (DBQ), and a long essay question (LEQ).

Every page on this site is aligned to the College Board's official AP World History curriculum and completely free. Use what works for your study style — flashcards if you're an active recall learner, the cheat sheet if you want a one-page overview, podcasts for studying on the go, or practice questions to test yourself before the exam.
