Paper 1 is a source exam, not an essay: Paper 1 checks how well you read, use, and judge sources — not how much history you can recall. You get four sources on one prescribed subject and answer four set questions.

Your prescribed subject here is The Move to Global War. That means your four sources will be about the aggression of the 1930s.

Here is the best news about Paper 1. The question types never change: every exam asks the same four things, in the same order, worth the same marks.

So you can drill a fixed method for each one long before you ever see the sources.

Your own knowledge of the case study still matters, but only the last 9-mark question rewards it directly. The first three questions are won or lost purely on how you handle the provenance and content of the sources in front of you.

This unit has two case studies. The Asia case study is Japanese expansion in East Asia, 1931–1941 — from the Mukden Incident to the attack on Pearl Harbor.

The Europe case study is German and Italian expansion, 1933–1940 — Hitler tearing up the Treaty of Versailles and Mussolini's hunt for empire.

Whichever case study you get, the same source skills carry you. You read each source, judge it as evidence, and — only at the end — bring in facts of your own.

  • Read the provenance line every time. It tells you the author, date and type of source. It is free information, and it does half the work on the value question for you.
  • OPVL is the method for the value question. It turns a source into evidence a historian can weigh.
  • Watch for common source types. Expect a government statement, a League of Nations report, a dictator's speech, a newspaper on appeasement, and a modern historian's verdict.
Memory hook — '3-2-4-6-9': The marks run 3, 2, 4, 6, 9 down the page and add up to 24. Spend about one minute per mark, and remember 3-2-4-6-9 to remember the whole paper.

Each question is unlocked by its command word — the verb that tells you exactly what to do. Learn what each one is asking, and the method that earns the marks follows.

1

Q1(a) — Comprehension [3 marks]

Starts 'What, according to Source X, were…'. State three separate points the source actually makes — each clear point earns 1 mark. Stay inside the source and add no outside knowledge. If the source says Japan acted to 'defend the railway' at Mukden, that is one point — find three like it.

2

Q1(b) — Message [2 marks]

Starts 'What does Source X suggest about…', usually about a cartoon, photo or map. Give the overall message — what the source wants you to think or feel — and back it with one detail. A British cartoon of Hitler swallowing Austria whole is warning about salami tactics; say that, do not just describe it.

3

Q2 — Value and limitations [4 marks]

Starts 'With reference to its origin, purpose and content, analyse the value and limitations of Source X…'. Use the provenance line. Give a value AND a limitation, each tied to a real feature, and link both to the exact topic named. Frame it as 'BECAUSE it was written by… FOR…, it is useful for… but limited because…'.

4

Q3 — Compare and contrast [6 marks]

Starts 'Compare and contrast what Sources X and Y reveal about…'. Give both similarities and differences, and link the two sources to each other. For example, a Japanese army statement and a League report on Manchuria may agree on the facts but clash on who was to blame. Never write two separate paragraphs that never meet.

5

Q4 — Judgement [9 marks]

Starts 'Using the sources and your own knowledge, evaluate the view that…'. This is a mini-essay: short intro, both sides using the sources as evidence, your own facts woven in, and a clear verdict at the end. It is the only question where knowing the history — dates like the Rhineland (1936) or Munich (1938) — pays off directly.

Comprehend → Message → OPVL → Compare → Judge (3-2-4-6-9).

QuestionMarksCommand wordWhat wins the marks
Q1(a)3What, according to…Three separate points from the source
Q1(b)2What does X suggest…One backed-up message
Q24Analyse value and limitationsValue AND limitation tied to origin, purpose, content
Q36Compare and contrastLinked similarities AND differences
Q49Using sources and own knowledge…Both sides + own facts + verdict

Source-handling (Q1–Q3)

  • Stay INSIDE the sources
  • No outside knowledge needed
  • Reward technique: points, message, OPVL, linking
  • Worth 15 of the 24 marks
  • Win these with method, not memory

Judgement (Q4)

  • Use sources AND your own knowledge
  • Needs facts the sources do not give you
  • Reward argument: both sides plus a verdict
  • Worth 9 marks — the biggest single question
  • Win this with knowledge AND a clear verdict
Turning a fact into Q4 evidence: Suppose Q4 asks whether appeasement caused Hitler's successes. A source might quote Hitler promising Munich was his 'last demand'. Your own knowledge then adds what the source leaves out: the Rhineland gamble of 1936, the Anschluss of 1938, and Hitler breaking his promise by taking all of Czechoslovakia in March 1939. Source detail plus wider context is exactly what the top band rewards.

How this is tested: Q2 always uses OPVL. The big trap is to describe the source instead of judging it as evidence. A second trap is treating bias as if it makes a source useless — bias is itself a value, because it shows what people wanted believed.
Source B (invented for practice): A public statement issued by the Japanese Kwantung Army in September 1931, days after the Mukden Incident: 'Chinese soldiers attacked our railway line near Mukden. Our troops acted only to defend Japanese lives and property. Order and prosperity will now return to Manchuria under our protection.'
IB-style questionAnalyse value and limitations[4 marks]

With reference to its origin, purpose and content, analyse the value and limitations of Source B for a historian studying Japan's seizure of Manchuria in 1931.

Common mistakes: 1. Describing the source instead of judging it. 2. Treating bias as useless — bias limits facts but is valuable for attitudes. 3. Forgetting to link back to the named topic. 4. Giving only a value or only a limitation — Q2 needs both. 5. Inventing provenance — use only what the attribution line states.
