How A Level History is Assessed: Cambridge 9489 is Undergoing Changes from 2027, So Verify the Options and Topics First
Based on the official Cambridge International 9489 History syllabus, this article explains the answering techniques, duration, marks, and weightings for the four papers (Source Analysis, Outline Study, Interpretations, and Depth Study), the four assessment objectives, the three options and topics (Europe, USA, and International), the topic rotation rules between Paper 1 and Paper 2, the topics dropped and added from 2027 along with the reorganization of the USA option, and how to prepare for source questions, essay questions, and historical interpretations.
A-Level History is a common choice for students applying to humanities and social sciences majors such as history, political science, international relations, and law. This article focuses on Cambridge International 9489. Two points need to be clarified first:
- Cambridge 9489 is being revamped starting with the 2027 exams: some topics have been removed, new topics added, and the US History option has been completely restructured;
- Edexcel also offers IAL History, but we were unable to directly obtain its syllabus PDF from the Pearson website (due to dynamic page loading), so this article only covers Cambridge 9489. We later organized Edexcel's four units, the options for each unit, and the combinations that cannot be taken together based on the official Pearson guide in the article How to Choose Edexcel IAL History Options.
Based on the official Cambridge syllabus, this article explains how the exams work, what changed in 2027, and how to prepare. For the US system equivalents, you can refer to AP US History and AP World History; for general A-Level rules, see How to Score an A* in A-Level.
I. The Four Papers
| Paper | Format | Time / Marks | AS Weighting | A Level Weighting |
|---|---|---|---|---|
| Paper 1: Source Analysis | One two-part source question (on the specified topic from the chosen option) | 1 hour 15 mins / 40 marks | 40% | 20% |
| Paper 2: Outline Study | Two two-part questions (on the specified topic from the chosen option) | 1 hour 45 mins / 60 marks | 60% | 30% |
| Paper 3: Interpretations | One interpretations question | 1 hour 15 mins / 40 marks | — | 20% |
| Paper 4: Depth Study | Two essays out of three | 1 hour 45 mins / 60 marks | — | 30% |
Three pathways: AS only; A Level taken over two years; A Level taken in a single series.
Assessment Objectives
| Objective | AS | A Level |
|---|---|---|
| AO1 Historical knowledge: recall, selection, and use of appropriate historical knowledge | 40% | 45% |
| AO2 Historical explanation, analysis, and judgment (cause and effect, change and continuity, similarity and difference, significance, etc.) | 30% | 30% |
| AO3 Sources: understand, analyze, evaluate, and interpret sources in context | 30% | 15% |
| AO4 Interpretations: understand how historians interpret and study the past | — | 10% |
II. Content and Options (From 2027)
AS (Papers 1 & 2): Choose one of three options
| Option | Topic |
|---|---|
| Europe: Modern Europe 1774–1924 | France 1774–1814; Liberalism and nationalism in Germany 1815–71; Russia from autocracy to revolution 1881–1924 |
| USA: US History 1820–1941 | The Civil War and Reconstruction 1820–77; The Gilded Age and Progressive Era 1870–1920; The Great Crash, the Great Depression, and the New Deal 1920–41 |
| International: International History 1870–1939 | Imperialism and the rise of world powers c.1870–1918; International relations 1919–29; International history 1929–39: the rise of extremism and the road to war |
Pay special attention to the "rotation" rule: Each option has three topics, which rotate between Paper 1 and Paper 2 each year; in the same year, the topic specified for Paper 1 will not be used for Paper 2. When preparing, check your exam year to confirm which topic is tested in the source question and which two are tested in the outline questions.
A Level
Paper 3 (choose one of three): Origins of the First World War; The Holocaust; Origins and development of the Cold War.
Paper 4 (choose one of three options):
- Europe: Europe 1919–41 (Mussolini's Italy, Stalin's USSR, Hitler's Germany);
- USA: The USA 1945–93 (The Truman and Eisenhower years, 1961–74, 1974–93);
- International: International History 1909–94 (The Soviet sphere of influence in Eastern Europe 1953–91; The end of minority rule in South Africa and Zimbabwe 1948–94; The road to independence in Malaysia and Indonesia 1909–67).
III. What Changed in 2027
According to the official syllabus change notes (not an exhaustive list):
- Topics removed: "The Industrial Revolution in Britain 1750–1850" from the AS Europe option; "China and Japan 1912–45" from the AS International option; "Britain 1919–39" from the A Level Paper 4 Europe option; and the original Cold War US-Soviet relations, decolonization in Sub-Saharan Africa, the spread of communism in East and Southeast Asia, and the Middle East conflict topics from the International option;
- Topics added: The three topics mentioned above have been added to the A Level Paper 4 International option;
- USA option restructured: The AS section has been consolidated from four topics to three;
- Minor adjustments have been made to the key questions, timeframes, and content of other topics; Paper 3 content remains unchanged.
Students using older textbooks and past papers should double-check whether their chosen topics are still being tested.
IV. How to Prepare
Here is some practical advice based on our experience.
- Confirm your option and exam year first: The content of the three options is completely different. Confirm your chosen option with your teacher and check the topic rotation for your exam year;
- Source questions: Analyze provenance, purpose, context, and reliability, and compare different sources rather than just summarizing the content;
- Essay questions: Start with a clear thesis, support it with specific historical evidence, compare the importance of different factors, and conclude with a well-substantiated judgment (the "judgment" in AO2);
- Interpretations (Paper 3): Be able to identify the argument and approach in a piece of historical writing, and explain why the historian interprets it that way;
- Build a solid foundation of specific historical facts: AO1 accounts for 45% of the A Level, so names, events, dates, and statistics must be accurate.
Final Thoughts
The key to A-Level History is solid knowledge, well-judged arguments, and the ability to analyze sources and historical interpretations. With the 2027 Cambridge revamp removing and adding certain topics, be sure to verify your options and topics against the new syllabus before registering.

Verification note: This article was verified against official materials in September 2026: the four papers, task requirements, time, marks, weightings, exam pathways, four assessment objectives and their weightings, options and topics, topic rotation rules, as well as the removals, additions, and restructuring from 2027, are all sourced from the Cambridge International AS & A Level History 9489 syllabus for examination in 2027, 2028 and 2029 (published in April 2025); the Edexcel IAL History course page exists, but the syllabus PDF could not be directly obtained from the page, so it is not covered in this article. The preparation advice is based on our practical experience.
