IB Economics HL

HL covers additional content, including theory of the firm extensions and macroeconomic HL topics such as the Phillips curve, and adds a third external paper focused on policy problems. Quantitative and evaluative demands are higher. SL candidates sit fewer papers and cover a narrower syllabus, so HL rewards stronger diagram and calculation fluency.

External papers test extended-response essays, data response based on a source extract, and, at HL only, policy-focused problems. Internal assessment is a portfolio of three commentaries linking news articles to different parts of the syllabus. Each component carries a weighting set by the official body, which publishes the current details.

Time limits, mark totals and weightings change between syllabus reviews, so do not rely on second-hand figures. The official body publishes the current paper structure, durations and weightings for your examination session. Confirm them there before planning exam timing practice or mocks.

IB results are reported on a 1–7 grade scale for the subject, combined with other components for the diploma. Grade boundaries are set after each session and are not fixed in advance. The official body publishes boundaries and statistical results; treat any remembered numbers from past years as unreliable.

Retake and resit arrangements depend on your session and registration category, and they differ for school candidates and private candidates. The official body publishes the rules and deadlines. Ask your coordinator early, because registration windows close well before the examination session.

The content is accessible, but the marks sit in evaluation and application, not recall. Strong candidates can define terms and draw accurate diagrams quickly, then use them to weigh trade-offs in unfamiliar contexts. Candidates who memorise model answers often plateau around the middle grades because they describe rather than judge.

Unlabelled or unshifted diagrams, definitions that are vague rather than precise, and essays that list points without a judgement. In data response, candidates also lose marks by ignoring the extract or failing to use the quantitative evidence. In commentaries, weak marks usually come from an article that is thin on economics or a link to theory that is asserted, not explained.

Follow the natural sequence: introductory concepts, microeconomics, then macroeconomics, the global economy and development. Build diagram and definition fluency in parallel with content, and start commentaries early, spreading the three across the two years so each links to a different syllabus section and a genuinely recent article.

Practise planning under time pressure: define key terms, select two or three diagrams, and decide your evaluation before writing. Then write full answers and mark them against the assessment criteria, focusing on whether your judgement is supported. Reading applied economics journalism regularly gives you concrete examples to deploy.

You need confident arithmetic, percentages, index numbers and simple algebra for elasticity and cost calculations, plus the ability to interpret graphs. HL demands more of this than SL, but the emphasis remains on explaining what a calculation means for consumers, firms or the economy, not on advanced mathematics.
