ExploreAbout this exam
IB Economics SL is the standard-level economics course within the International Baccalaureate Diploma Programme, assessed by external papers and an internally assessed commentary portfolio. It suits students who want a rigorous, internationally recognised qualification in economic reasoning rather than a purely vocational or single-country syllabus. The course builds from scarcity and opportunity cost through competitive markets and market failure, then macroeconomics - aggregate demand and supply, objectives, and fiscal, monetary and supply-side policy - before turning to trade, exchange rates, the balance of payments, development and globalisation. Assessment rewards applied reasoning: you must use economic models and terminology to analyse real situations and evaluate policy, not just recall definitions. Strong preparation means learning each diagram until you can draw and label it from memory, practising data-response questions that require calculation and interpretation, and building a habit of writing balanced evaluation that weighs costs against benefits and short run against long run. The internal assessment rewards choosing news extracts with genuine economic content and linking them explicitly to theory. Always confirm current assessment arrangements, timetables and fees with the IB and your school, since these are published officially and change over time.
What you'll study
About IB Economics SL preparation
What does the IB Economics SL assessment actually consist of?
Two external papers plus internal assessment. Paper 1 asks extended-response questions based on stimulus material; Paper 2 is data response, including quantitative work and policy evaluation. The internal assessment is a portfolio of commentaries, each linking a news media extract to economic theory. Check the current IB Economics guide for the precise structure and weightings, which the IB publishes.
How difficult is SL compared with HL?
The SL syllabus covers the same core areas but with less breadth and depth, and the quantitative demand is lighter. Difficulty usually comes from evaluation and application rather than mathematics. Students who memorise definitions but cannot apply models to unfamiliar data tend to find it harder than expected, regardless of level.
How long is the exam and how many questions are there?
The IB publishes the current paper durations, question counts and weightings in its official Economics guide and subject pages. Those details are revised periodically, so confirm them there or with your teacher rather than relying on second-hand summaries. Plan your practice under the official timing once you have it.
Can I retake IB Economics SL?
Retake arrangements, including whether you may retake individual components or must resit whole sessions, are set by the IB and your school. The official body publishes current rules and any associated fees. Ask your DP coordinator early, because registration deadlines for retake sessions fall well before the exam period.
What is the best order for studying the syllabus?
Follow the logical build: introduction to economics, then microeconomics, then macroeconomics, then the global economy. Microeconomic models underpin later policy analysis, and macroeconomic policy makes little sense without demand and supply. Interleave diagram practice and past-paper questions as you go rather than leaving all revision to the end.
Why do candidates lose marks in evaluation questions?
Common causes are one-sided answers, no reference to the diagram just drawn, vague assertions without mechanism, and ignoring time frames or stakeholder differences. Evaluation needs explicit reasoning: state the condition under which your judgement holds, and weigh magnitudes rather than listing points. Use the model, then critique it.
How should I choose articles for the commentary portfolio?
Pick recent news extracts with clear economic content and enough substance to support a diagram and evaluation. Avoid pieces that are purely political or too short to analyse. Each commentary should identify the concept, apply the model, and evaluate. Confirm the current rules on article dates, number of commentaries and word limits with your teacher.
Do I need strong maths for SL?
You need confident arithmetic and the ability to calculate and interpret percentages, index numbers, elasticities and simple changes. The emphasis is on explaining what a calculation means economically, not on advanced mathematics. Practise showing working clearly, since method marks are often available even when the final answer is wrong.
What separates a grade 6 or 7 answer from a mid-range one?
Top answers use precise terminology, accurate and labelled diagrams, and applied examples, then evaluate with genuine judgement. They address the specific question rather than dumping everything known about the topic. Structure matters: define, analyse with a model, evaluate, conclude. Practise under time pressure so this structure becomes automatic.
