Paper 1 at a glance

Two sections, one option each: Section A (period study, choose one of four) and Section B (wider world depth study, choose one of five). Confirm your school’s exact two options before revising anything.

Section Options Focus
A: Period study America 1840-95, Germany 1890-1945, Russia 1894-1945, America 1920-73 Broad political/economic/social change over decades
B: Wider world depth study WWI, Inter-War Years, East-West 1945-72, Asia 1950-75, Gulf/Afghanistan 1990-2009 Tighter focus on causes/course of specific conflicts

The two skills every option tests

Regardless of which options your school teaches: causation (why did things happen/change) and change and continuity (how far did things change over time). Build revision notes around these two questions for your specific content, not around isolated facts.

The shared three-part shape

Both period studies and depth studies tend to follow a three-phase structure: an opening phase (establishment or aftermath of something), a middle phase (crisis, upheaval or diplomatic effort), and a final phase (lived experience or breakdown into renewed conflict). Revising all three phases evenly — not concentrating only on the most dramatic middle section — covers the specification properly.

Worked example: long-term, short-term, trigger

For any causation question, sort causes into three categories and show how they interact:

Long-term:    underlying conditions built up over years/decades
Short-term:   events in the run-up to the outcome
Trigger:      the specific event that precipitated it
Connection:   explain how the three reinforced each other -- naming
              all three without connecting them caps marks at the
              lower half of the top level

Building an answer to a “how far” question

Change-and-continuity questions ask you to weigh the extent of change, not just describe it. A reliable structure: state what changed, state what stayed the same (or changed only superficially), then reach a judgement on balance. For example, in AD America 1920-73, political rights expanded significantly for African Americans through the Civil Rights movement, but economic inequality persisted in many respects — a strong answer weighs both sides explicitly before concluding, rather than presenting only the changes and ignoring the continuities.

Source-based questions

Because Paper 1 also includes source-based tasks, practise the standard approach: identify what a source shows, consider its origin and purpose (why was it produced, by whom, for whom), and use this to evaluate its usefulness or reliability for a specific historical enquiry — rather than treating a source purely as a fact to describe. This skill applies across whichever period study and depth study your school has taught, since the source-handling technique itself does not depend on the specific content.

Exam traps

  • Revising an option your school did not actually teach — always confirm exact options first.
  • Treating Section A and Section B as needing the same style of answer, when period studies test broader sweep and depth studies test tighter causal focus.
  • Writing a narrative of events without addressing the specific concept (causation, consequence, change/continuity) the question asks for.
  • Confusing this Paper 1 content with the Historic Environment Study, which sits in Paper 2.

Interpretation questions

Some Paper 1 tasks also ask you to evaluate two differing historical interpretations of an event — distinct from evaluating a primary source’s origin and purpose. Here the focus shifts to why two historians might reach different conclusions from broadly similar evidence: differences in which evidence they emphasise, the questions they set out to answer, or the historical context in which they were writing. Practise explaining a difference between two interpretations in terms of what each historian focused on, rather than simply asserting that one interpretation is more convincing without evidence for the claim.

Building a revision timetable around your two options

Because Paper 1 tests two entirely separate historical narratives (your period study and your depth study), avoid revising them as a single undifferentiated block of “history content.” Allocate distinct sessions to each, and within each session revise the same recurring skills (causation, change and continuity, source evaluation, interpretation) applied to that specific content — this reinforces the transferable skill while keeping the two bodies of factual knowledge appropriately separate in memory.

Linking content knowledge to the assessment objectives

Paper 1 assesses AO1 (knowledge and understanding), AO2 (explaining and analysing causation, change, continuity, consequence and significance), and AO3 (analysing and evaluating source material and interpretations). Structured questions typically move from a lower-tariff AO1 recall question through to a higher-tariff AO2 or AO3 extended-writing question — so a revision session that only drills facts (AO1) leaves the highest-value marks unpractised. Pair every content-recall session with at least one timed extended-writing practice question drawing on that same content.

Self-test

  1. How many options must a school choose across Paper 1, and from which two sections?
  2. Name the two historical concepts every option is tested against.
  3. What three-category structure should a causation answer use?
  4. Why should a strong answer connect the three categories rather than just naming them?
  5. Which paper does the Historic Environment Study belong to?

Answers: 1. Two — one period study from Section A, one wider world depth study from Section B. 2. Causation and change/continuity. 3. Long-term causes, short-term causes, and the trigger event. 4. Because naming all three without explaining how they reinforced each other caps marks at the lower half of the top level — connection is what the highest marks reward. 5. Paper 2.
