IB Economics Revision Guide (2026 Exam)
Everything you need to prepare for the IB Economics exams: a paper-by-paper strategy for Papers 1, 2 and the HL Paper 3, a 6-week revision timeline, and unit checklists. Each topic links straight to free notes and flashcards so you can close the gaps you find.
⭐ Predicted Topics for IB Economics 2026
Want to know which diagrams and concepts are most likely to appear? We've analysed past papers across every session to surface the highest-frequency topics — supply and demand shifts, elasticity, market failure, AD/AS, and government intervention recur almost every year. Revise everything, but weight your final weeks toward these high-probability areas and the diagrams that go with them.
Essential Economics Command Terms for Paper 1 and Paper 3
Economics marks are won and lost on the command term. A part (a) that asks you to 'explain' wants a labelled diagram and a clear chain of reasoning; a part (b) that asks you to 'evaluate' or 'discuss' wants both sides and a justified judgement. Match the verb to the response and you protect the easy marks.
Explain
Give a detailed, reasoned account of how or why something happens. In Economics this almost always means a clearly labelled diagram plus a step-by-step chain of analysis linking cause to effect.
Evaluate
Weigh up strengths and weaknesses to reach a judgement. Consider short vs long run, different stakeholders, magnitude, and assumptions — then commit to a justified conclusion rather than sitting on the fence.
Calculate
Obtain a numerical answer, showing the working and the correct units. Common in Paper 2 and HL Paper 3: PED, the multiplier, price floors and ceilings, tax incidence, and welfare-loss areas.

Know the papers
The biggest revision mistake is studying content but ignoring format. Know exactly what each paper asks for before you start practising.
Extended response. Choose one question from a choice of three (each drawn from a different syllabus unit). Every question has a part (a) worth 10 marks and a part (b) worth 15 marks — 25 marks in total. No calculator and no data; this paper rewards clear diagrams and structured analysis.
- Part (a) "explain": one or two accurate, fully labelled diagrams and a tight chain of reasoning
- Part (b) "evaluate/discuss": both sides, a real-world example, then a justified conclusion
- Choose your question by the diagram you can draw most confidently, not just the topic name
- Use a CLEUP/PEEL-style structure and define key terms early to bank the knowledge marks
Data response. Answer all parts of one question built around a real-world text and data extracts — 40 marks. A calculator is allowed. Lower-mark parts test definitions and calculations; the final part is an extended evaluation worth 15 marks that must use the stimulus.
- Calculation parts: show the formula, substitute, and give units — method marks are awarded
- Quote the text and data directly ("paragraph 3 states…") to anchor every point in the stimulus
- Draw diagrams even when not explicitly asked — they earn analysis marks
- Leave 25+ minutes for the 15-mark evaluation; it carries the most marks of any single part
Policy paper, HL only. Answer two compulsory questions — 60 marks. It is heavily quantitative: you apply HL calculations and then write a policy recommendation. Tests the HL extension material (e.g. PED/PES, tax and subsidy incidence, the Keynesian multiplier).
- Master every HL calculation: elasticities, the multiplier, price controls, tax/subsidy incidence
- For the policy recommendation, evaluate at least two measures and justify your choice
- Show all working — partial method marks rescue an arithmetic slip
- Practise reading a diagram off a set of numbers and a numerical answer onto a diagram
6-week revision timeline
Starting 6 weeks out gives you enough time to go through all 4 units, identify weak spots, and do meaningful exam practice.
- Work through all notes for each unit — use the topic index on /ib-economics
- Build a diagram bank: redraw supply/demand, elasticity, externalities and AD/AS from memory
- Make key-term flashcards for Units 1 and 2 (definitions plus a real example each)
- Begin spaced flashcard review across all four units
- Attempt one full Paper 1 essay (a + b) under timed conditions
- HL: drill the Paper 3 calculations — PED, the multiplier, tax incidence and price controls
- Complete at least two full Paper 2 data-response questions, calculator included
- Target weak topics from practice — most often market failure and macro policy trade-offs
- Collect a short bank of current real-world examples to drop into evaluation answers
- Review mark schemes — see exactly how analysis and evaluation marks are awarded
- Skim every unit summary and diagram sheet — reinforce, don't re-read in full
- Continue daily flashcard review (due cards only)
- Quick scan of key definitions, formulas, and your diagram bank
- Check command terms: define, calculate, explain, analyse, discuss, evaluate
- Prepare calculator and equipment, get 8 hours sleep
Revise by unit
Each unit has a different exam weight. Prioritise accordingly — but don't skip any unit entirely.
Introduction to Economics
Exam weight: Low — foundational concepts that frame every other unit rather than standalone questions
Microeconomics
Exam weight: Very High — demand and supply, elasticity and market failure appear in almost every session
Macroeconomics
Exam weight: High — AD/AS, the multiplier and policy trade-offs are core Paper 1 and Paper 3 material
The Global Economy
Exam weight: Medium–High — trade, exchange rates and development frequently anchor data-response questions
IB Economics Revision FAQ
How long should you revise for IB Economics?
Start dedicated Economics revision about 6 weeks before the exam. That gives you enough time to rebuild every core diagram from memory, lock down the key terminology, drill the HL calculations if you take Higher Level, and complete several full past papers under timed conditions.
Is IB Economics hard?
Economics is conceptually accessible but the exams reward precision. The challenge is not difficult maths — it is drawing accurate diagrams under time pressure, using terminology correctly, and writing balanced evaluations that reach a justified judgement. HL adds the quantitative Paper 3, which demands confident calculation and policy analysis.
What topics come up most in IB Economics?
Microeconomics dominates: supply and demand shifts, price and income elasticity, and market failure (externalities and government intervention) recur almost every session. In macro, AD/AS analysis and the trade-offs between fiscal and monetary policy are exam staples. Check our Predicted Topics page for the latest data-driven breakdown.
How do you get a 7 in IB Economics?
Master the command terms — especially "evaluate" and "discuss" — and always finish with a justified conclusion. Draw fully labelled diagrams for every analysis point, keep a bank of current real-world examples to apply in essays, and for HL practise the Paper 3 calculations until they are automatic so the policy recommendation is where you spend your thinking time.
