AP World History — the world from 1200 to 1450

Units 1 and 2 of AP World History: Modern cover the world from about 1200 to about 1450 and are worth between 16 and 20 per cent of the exam between them. The first looks at states and belief systems region by region; the second at the networks that connected them. This set takes ten of their ideas, one question each.

Most of these are causal rather than definitional, because that is what the exam rewards. The Song examination question asks not what the examinations were but what they changed: office held by birth became office held by demonstrated command of a textual tradition, and a scholar-gentry replaced a hereditary aristocracy at the centre of the state. The Champa rice question asks for the chain rather than the agronomy — a variety that ripens in half the time allows a second harvest, a second harvest feeds more people, and China's population roughly doubled across the period.

Two questions are really about economics wearing historical clothes. The Silk Roads carried silk, porcelain and gems; the Indian Ocean carried those and also timber, grain and salt in quantity. The reason is freight cost: a camel carries two hundred kilograms and must be fed and watered for months, so its cargo has to be worth a great deal per kilogram, while a dhow carries many tonnes and the wind is free. And what made overland trade expand in this period was not a new vehicle but caravanserai a day's march apart and credit instruments that let a merchant travel without carrying silver — infrastructure and finance rather than technology.

The Mongol question is the one students most often get wrong by trying to be fair. The conquests killed on a vast scale and levelled cities; the single authority that followed made travel across Eurasia safer and cheaper than it had been in centuries. Both are true simultaneously, and every wrong answer resolves the tension by discarding one half. The plague question closes the same circuit: the disease appears first in ports and route towns, ahead of countryside much nearer its origin, because the network that had been moving porcelain and paper for a century did not distinguish between cargoes.

On method, two things are deliberate. Every distractor is a mistake a candidate could really make — dating an institution to the wrong dynasty, crediting conquest with what commerce did, reading a later political idea back into the thirteenth century — and each explanation says which one produces which answer. And no modern translation of a medieval text is quoted anywhere, since published translations are themselves in copyright; where a traveller's account matters, it is described and attributed rather than quoted.

The limit worth naming: real Section I questions come in sets of three or four hung off a source — a map, an image, a chart, an excerpt. There are no sources here, so every question stands on its own text.

• Explain what the Song examination system changed about the basis on which office was held
• Account for the spread of Islam and Islamic learning into regions no Muslim army conquered
• Describe how Khmer rulers made a claim to divine authority visible through temples and waterworks
• Hold both halves of the Mongol record together — destruction and connection — without discarding either
• Identify caravanserai and credit instruments as the infrastructure that made overland trade expand
• Explain from freight costs why the Indian Ocean network moved bulk goods and the Silk Roads moved luxuries
• Describe the gold and salt exchange on which Mali's wealth rested, and place Ghana correctly before it
• Trace the consequence of Champa rice from ripening time to harvest to population
• Contrast European manorial obligation with the tenancy and taxation of a monetised Chinese peasantry
• Read the plague's geography as evidence about the trade network that carried it

Built against the published structure of AP World History: Modern. Unit 1, The Global Tapestry, and Unit 2, Networks of Exchange, both cover c. 1200 to c. 1450 and are each weighted at 8 to 10 per cent of the exam. The exam runs 3 hours 15 minutes and is taken digitally: 55 multiple-choice questions in 55 minutes for 40 per cent of the score, presented in sets built on sources; three short-answer questions in 40 minutes for 20 per cent; then a Document-Based Question with a recommended 60 minutes including a 15-minute reading period for 25 per cent, and a Long Essay Question in 40 minutes for 15 per cent. No modern translation of any medieval text is quoted in this material — published translations are themselves in copyright — and real accounts are described and attributed instead of quoted. Nothing is reproduced from any College Board publication, released exam or scoring guideline. Zestly is an independent study tool. It is not affiliated with the College Board, which owns the AP World History exam, and it is not an exam centre.
