# AP World History: The Comparison Skill That Appears on Every Exam
AP World History: Modern covers roughly 1200 CE to present. With such an enormous scope, students who try to memorize everything burn out. The exam rewards those who can identify patterns across civilizations and time periods — comparison is the core skill.
Exam Structure
3 hours 15 minutes: 55 MCQs (55 min), 3 SAQs (40 min), 1 DBQ (60 min), 1 LEQ (40 min). The essays (DBQ + LEQ) together are worth 40% of your score.
The Comparison Framework
Nearly every LEQ prompt and many SAQ prompts ask you to compare across regions, time periods, or civilizations. Use the SPICE-T framework for every comparison:
For any comparison prompt, pick 2-3 SPICE-T categories where you can identify both similarities AND differences. The exam rewards nuance — saying "X and Y were similar in trade but different in political structure" scores better than saying "X and Y were completely different."
Unit Weighting
The post-1450 period accounts for roughly 75% of the exam. The Columbian Exchange, Atlantic slave trade, industrialization, imperialism, decolonization, and globalization are the highest-frequency topics.
The SAQ Strategy
SAQs are 3-part questions worth 3 points each. Each part requires a specific historical example with a brief explanation. The trap: students write too much. One example + 2-3 sentences of explanation per part is sufficient. Spend no more than 12 minutes per SAQ.
High-Frequency Comparisons to Prepare
If you can write a solid comparison essay for each of these five topics, you're prepared for the majority of possible LEQ prompts.
