What changes for the May 2027 AP World History exam

Section II gives one DBQ and one required LEQ. College Board recommends an hour for the DBQ, including a 15-minute reading period, and 40 minutes for the long essay. The DBQ is 25% of the exam score and the LEQ 15%. Older papers can help with historical reasoning, but they may show a different choice of long-essay prompts.

From May 2027 the LEQ provides one broad prompt. It allows students to focus on one or more of the developments referenced in it. College Board expects a defensible claim, relevant contextualization and at least two pieces of specific, relevant evidence, with developed analysis. Follow the wording of the actual prompt and use the official rubric when reviewing practice.

A worked DBQ paragraph using practice documents

Original practice question. To what extent did maritime commerce change economic relationships across the Pacific from the sixteenth century? Imagine that Document A is an invented port register listing goods and destinations, and Document B is an invented merchant petition complaining about restrictions. These notes are practice material, separate from the historical example that follows.

A port register listing both silver and manufactured goods would support an argument that exchange connected markets with different kinds of demand. Its administrative purpose would make it useful for tracing registered cargo. It would offer less evidence about unrecorded trade or merchants’ motivations. A merchant petition, by contrast, could show that traders saw imperial rules as a constraint. Its persuasive purpose matters because the writer might emphasize burdens in order to obtain a change. The documents would contribute different evidence to the same argument about regulated exchange.

This paragraph treats sourcing as an explanation of how a document can support a particular claim. A title or profession alone gives little analysis. Name the feature, link it to what the source records or emphasizes and explain how that affects the argument.

A historical example for a long-essay argument

The Manila galleon trade linked Manila and Acapulco. According to the Metropolitan Museum of Art, Asian goods including porcelain and silk moved to Mexico through the route in exchange for silver from the Americas. The example can support an argument about interregional integration because it identifies the places, goods and direction of exchange.

A paragraph can use the example to explain a change in trade connections. To show continuity as well, look for a distinct example or verified evidence of practices that persisted. State exactly what continued. Continuing demand for a commodity is a different claim from continuing use of the same trading institutions.

For a long essay, build an argument from multiple specific examples suited to the prompt. If you use the Manila case as one example, choose a second development you have studied and can describe accurately. It should extend, qualify or contrast with the argument rather than repeat that trade expanded.

How to fence a DBQ or LEQ word

1. Base. The route increased integration. 2. Detail. The route increased commercial integration between Manila and Acapulco. 3. Tone. The route linked markets with different demands for goods. 4. Logic. By carrying Asian manufactures and American silver across the Pacific, the route made exchange between those markets more direct. 5. Transfer. A later transport route can link regional markets while leaving older local exchange practices in place.

Compare transformation and continuity. If a route changes the scale and direction of exchange, explain those changes. If some local practices remain, say which ones. An essay can use both terms when the evidence describes different dimensions of the same process.

Practise reading the task before choosing evidence

If a question asks about causation, identify the development and explain how the causes worked. If it asks for comparison, use a common feature such as state control or the role of merchants. If it asks about continuity and change, compare the same feature at two moments. Choose examples after deciding which reasoning move the prompt needs.

What makes contextualization useful? It shows how a relevant broader development helps explain the question. How should I use the documents? Support claims with their content and explain why sourcing matters when it affects the argument. Can I select a different LEQ in May 2027? The updated format gives one required broad prompt.

After a timed response, mark your thesis and every example. Draw a line from each example to the claim it supports. Check that you explain a connection or process between the two. If the line only points to a date or name, add the reasoning that makes that fact useful.

Word list · Fencing Method · Revision

Test the reach of a historical claim

A route can link distant markets without affecting everyone equally. A claim about merchant access, imperial revenue or the terms faced by workers would each need different evidence. When you write about integration, name the specific markets or people being integrated and explain what the connection changed.

Prepare a comparison by choosing the same question for both examples. Who controlled access to exchange? What goods moved? What changed for producers? If you compare a trading route with a tax policy, state the shared issue before discussing the difference. A clear comparison gives context and evidence a common purpose.

Practice workshop

Place the claim within the prompt’s period

Underline the dates in a practice question before planning. Check the date or period of each example. If an example falls outside the frame, it may still establish background where relevant, but it should not stand in for evidence about the specified period. Use dates as boundaries for the claim, not as decoration.

Give contextualization a purpose

Write a two-sentence context for a prompt about changing commercial relationships. The first can name a broader development and the second should explain how it matters to the issue. A reference to overseas empire becomes useful when it helps explain how rulers controlled or facilitated particular exchanges.

Decide what each document contributes

Imagine one document gives shipping figures and another reports a merchant’s complaint. The figures may support a claim about movement of cargo. The complaint may help explain the effects of regulation as perceived by a trader. Explain why neither answers the whole question on its own. Then decide how they can work together.

Explain sourcing through a specific claim

Name a document’s purpose and ask what it would make the author record, emphasise or omit. A list compiled to track cargo can be useful even if it tells us little about household consumption. State why the feature matters to the argument you are making. Avoid assuming that a source with a purpose must be unreliable.

Use outside evidence as a separate piece of reasoning

Add one verified example from your course knowledge that is not in the practice documents. Describe it clearly enough for a reader to know what happened and why it supports the claim. If it only repeats a document’s example, choose a different one. Give the new evidence a distinct role.

Make complexity visible through qualification

If a development connected markets more closely, ask whether that happened in the same way for merchants, producers and officials. A sentence that narrows the claim to one group can be more useful than several general statements about complexity. Explain which effect varies and what accounts for the difference.

Check an older paper before using it as a mock

An older long-essay question can be useful for practising historical reasoning. When simulating May 2027, use the current College Board format and answer one broad required prompt. Set time for planning and for checking that both specific examples support your thesis. Reserve a final pass for the reasoning that connects them.

Two specific examples for a broad maritime-trade LEQ

For a broader early modern question on how states shaped maritime trade, pair the Manila galleon route with Portuguese attempts to enforce a naval-pass system in the Indian Ocean. The Manila example can illustrate an empire maintaining a route that channelled exchange between distant markets. The Portuguese cartaz example can illustrate an attempt to control shipping by requiring passes.

Keep the claim proportional to each example. The galleon route shows a connection between markets. A pass system shows an effort to regulate access, and its existence alone does not establish complete control. If the question asks how states shaped commerce, compare the mechanisms. One channelled goods through a recurring route. The other tried to regulate which vessels could move under what conditions.

In a finished essay, place both examples within the prompt’s date range and explain why the comparison matters. It could support a judgement that states shaped trade through multiple means while continuing to depend on merchants and existing demand. If the actual question concerns the Pacific alone, choose evidence within that geographical scope.
