ExploreAbout this exam
IB History HL is the higher-level history course within the International Baccalaureate Diploma Programme, typically taken by students aged 16–19 across two academic years. It suits candidates who can read sources critically, hold several interpretations in tension, and write sustained analytical prose under time pressure. The course combines a prescribed source-based study assessed in Paper 1, world history topics assessed in essay form in Paper 2, and, at HL only, a regional and period depth study assessed in Paper 3. All candidates also complete an internally assessed historical investigation: a self-designed enquiry into a question of the student's choosing, with explicit attention to source evaluation and historiography. Preparation is cumulative rather than last-minute. Build a timeline-and-theme framework for each unit, practise reading primary sources for origin, purpose, value and limitation, and rehearse essay planning until a thesis and three or four structured paragraphs come quickly. Learn to name historians and schools of interpretation, and to weigh them rather than merely cite them. Marking rewards precise, evidence-anchored argument and penalises narrative retelling. The IB publishes current assessment details, session dates and fees; check its official site and your school's DP coordinator for the figures that apply to you.
What you'll study
About IB History HL preparation
What does the exam actually look like?
Paper 1 gives you a set of sources on the prescribed subject and asks short answer questions plus a source-based essay. Paper 2 offers world history topics and requires essay responses. Paper 3, HL only, examines your depth study region and period through essays. The historical investigation is internally assessed and externally moderated.
How is the course weighted across the papers?
The prescribed subject, world history topics, depth study and historical investigation each carry a share of the overall assessment, with the HL-only Paper 3 and the investigation together accounting for a large portion. Confirm the current weightings on the IB's official subject page, since these details are periodically revised.
How long are the papers and how many questions must I answer?
Structure varies by paper: Paper 1 is source-based with compulsory questions, while Papers 2 and 3 require you to choose from a list of essay questions. The IB publishes current durations and question counts in the subject guide; do not rely on older past papers for timing practice.
How hard is IB History HL compared with SL?
The extra demand is the depth study and the wider reading it requires. HL candidates must command detailed knowledge of one region and period, and write three essays in Paper 3. Students who find source analysis natural often struggle instead with the sheer volume of specific evidence needed for strong essays.
Can I retake a paper?
Retake arrangements, including which components can be resubmitted and whether the internal assessment carries over, are set by the IB and administered through your school. Ask your DP coordinator early, because deadlines and registration windows are strict. The IB's official site has the current regulations.
In what order should I study the components?
Start the historical investigation early, since it runs alongside taught content and needs its own research time. Build Paper 1 source skills steadily through the course. Treat Paper 2 topics as thematic frameworks rather than lists. Leave Paper 3 depth study consolidation for the final year, but keep notes organised from the start.
Why do strong students lose marks on essays?
The usual causes are narrating events instead of arguing, ignoring the question's command term, failing to address counter-arguments, and citing historians without evaluating their position. Weak source answers often describe a source's content while ignoring origin, purpose, value and limitation. Practise planning under timed conditions.
How should I use past papers?
Use them for timed planning and full written responses, then mark against the published criteria rather than a memorised model answer. Past questions reveal the command terms examiners favour. Space them out: writing four essays a week exhausts you, while one carefully reviewed essay a fortnight builds genuine improvement.
Do I need to memorise historians' names?
You need enough historiography to show awareness of debate, but names alone earn little. Learn two or three competing interpretations per major topic, be able to summarise their claims, and explain what evidence supports or undermines each. That habit serves Papers 2 and 3 and strengthens the investigation's critical framing.
