IB & IGCSE Economics · Far East Shopping Centre, Orchard · Lessons in English, 简体中文 & 한국어
In IB Economics, your grade turns on evaluation and real-world application — not how much theory you can recall. Most students understand the content and still lose marks. That gap is exactly what we coach.
KS Academia Prep runs IB Economics tuition for SL and HL students — every paper and the Internal Assessment — at Far East Shopping Centre, Orchard Road, Singapore, in English, Simplified Chinese and Korean.
Whether you’re at an international school in Singapore or preparing on your own, this is where structured, exam-precise IB Economics coaching lives — at both SL and HL.
The concepts make sense in class, yet the grade never reflects it. In IB the missing piece is almost always evaluation and application — the AO3 skills, not the content.
English is your second or third language. You can reason through market failure fluently in Korean or Mandarin — writing the marks-earning answer in English is the real hurdle.
The Internal Assessment and, for HL, Paper 3 are the parts students most underestimate — and where structured coaching makes the clearest difference.
Almost every student who struggles with IB Economics can explain the theory perfectly well in conversation. That is exactly why the marks feel so unfair.
IB doesn’t reward how much you know — it rewards evaluation and real-world application delivered in a specific shape. Paper 1’s part (b) is fifteen marks of pure evaluation. The data-response paper wants precise interpretation, not description. The Internal Assessment rewards applying a key concept to a real news article with a clear diagram and a genuine judgement. Students lose marks not because they don’t understand, but because nobody taught them how those marks are actually awarded.
This is a coachable skill, and it’s the one most self-study misses. Re-reading notes and re-watching videos builds familiarity, which feels like progress — but familiarity is not the same as producing a mark-scheme answer under timed conditions, or writing a commentary that hits the IA criteria. The only way to close that gap is to write, be marked against the real IB criteria, and be shown exactly where the marks were won and lost.
That is the whole of what we do. Small classes, structured notes, and — above all — practice that comes back marked against the actual IB criteria, with the specific next step to close the gap. Not “good, keep going,” but “here is the exact sentence that cost you the evaluation mark, and here is how to write it.”
Both routes cover the same syllabus and the same nine key concepts. Only one closes the gap between knowing the content and scoring on it.
Content is only half of IB Economics. These are the assessment realities that quietly cost marks — and the first ones we make sure a student actually understands.
The Internal Assessment is a portfolio of three commentaries, each on a real news article, each drawn from a different unit of the syllabus and applying a different key concept, and each a maximum of 800 words. It’s worth 20% at HL and 30% at SL, and it’s marked in-house then moderated by the IB. Students leave it too late and lose easy marks to structure, word count and concept choice — the most recoverable marks in the whole course.
Each Paper 1 question has a 10-mark part (a) and a 15-mark part (b) that is almost entirely evaluation, and top answers are built on real, current, specific examples. You can know every model perfectly and still cap your score without a bank of examples ready to deploy. Building that bank is deliberate work — not something that appears the night before.
Under the current syllabus, Paper 1 draws on all four units, not the two that older papers used to test. The old habit of quietly dropping a unit and hoping it doesn’t appear no longer works — there’s nowhere to hide a gap. Complete, even coverage is now the baseline, and it changes how you should revise.
Higher Level students sit a third paper SL students never face: a policy paper with quantitative work and a policy recommendation, with two compulsory questions. It rewards deliberate, repeated practice with the numerical and decision-making tools — not last-minute cramming. It’s the clearest marker of the HL step up, and the part most worth starting early.
Scarcity, choice, efficiency, equity, economic well-being, sustainability, change, interdependence and intervention frame the whole course — and the IA expects each commentary to apply a different one. Treated as an introduction to skim past, they quietly cost marks; used deliberately, they’re a ready-made structure for analysis and evaluation.
None of this is difficult once someone points it out. It only costs marks when a student meets it in the exam hall — or on IA submission day — instead of in a lesson. Making these visible early, then drilling them, is a large part of how a predicted 4 becomes the grade it should have been.
Both levels share the same nine concepts, Paper 1, Paper 2 and the Internal Assessment. HL goes wider and deeper and adds Paper 3. Here’s exactly what each level sits.
| Component | What it is | SL | HL |
|---|---|---|---|
| Paper 1 | Extended-response (essay) paper. Answer one of three questions; each has a 10-mark part (a) and a 15-mark part (b). Draws on all units.1 hour 15 minutes | 30% | 20% |
| Paper 2 | Data-response paper. Answer one of two questions using provided extracts; calculators allowed.1 hour 45 minutes | 40% | 30% |
| Paper 3 HL only | Policy paper. Two compulsory questions combining quantitative work with a policy recommendation.1 hour 45 minutes | — | 30% |
| Internal Assessment | Portfolio of three commentaries on real news articles — one per unit, each applying a different key concept, max 800 words each. School-marked, IB-moderated.Coursework | 30% | 20% |
Both levels think the same way about economics; HL simply goes wider and deeper, carries a heavier quantitative load, and adds Paper 3. HL suits students taking economics as a core subject or heading toward economics, business or related degrees; SL works well as a strong, broadening choice within your six.
The decision interacts with your whole subject combination and your target universities — which is exactly the kind of thing our IBDP subject consultation is built to think through before the choice becomes hard to reverse.
IB Economics (first assessment 2022) is built from four units and taught through nine key concepts, at both SL and HL. HL covers the same units in more depth, with extra content and the quantitative extension that Paper 3 tests.
The foundations: scarcity and choice, opportunity cost, factors of production, the basic economic problem, and how different economic systems allocate resources. The lens the whole course looks through.
How individual markets work — demand and supply, elasticity, market failure and government intervention. HL adds the theory of the firm and deeper cost, revenue and market-structure analysis.HL goes further
The national economy — measuring activity, the macro objectives, and demand-side and supply-side policy. Growth, inflation, unemployment, inequality and government debt, with policy trade-offs throughout.HL goes further
Trade and the wider world — benefits of trade, protectionism, exchange rates, the balance of payments, economic integration, and sustainable development including barriers and strategies.HL goes further
These conceptual lenses run through every unit, and the Internal Assessment requires each of your three commentaries to apply a different one — so they're not background reading, they're an assessed part of the course.

Our approach comes from one stubborn principle about how people actually learn abstract ideas — and from treating exam skill as something you coach, not something you hope for.
Opportunity cost, elasticity, market failure — every one describes a tension people already live through. We open with that tension, so the concept lands as an answer to a question you actually feel, not a definition to memorise and forget.
Most teaching leaves evaluation as “discuss both sides.” We break it into a drillable structure — mapping stakeholders, weighing short vs long term, judging magnitude and likelihood — and practise it until a balanced judgement becomes a habit, not a guess.
Writing without expert marking entrenches your mistakes. Every practice piece — and every IA commentary — comes back assessed against the real IB criteria, with the specific line that cost the mark and exactly how to fix it.
When a concept is fully understood in a student’s stronger language first, the English answer gets easier — not harder. We teach in English, Simplified Chinese and Korean so comprehension is never the thing standing between a student and the mark.
“Never open with the definition. Open with the tension the definition resolves.”
The gap between a 5 and a 7 is almost never content — it's evaluation, application and exam craft. Here's what actually separates a top script, and the structure we drill to get there.
A 7 in IB Economics comes from doing three things reliably: applying theory to real, current, specific examples rather than hypotheticals; evaluating — reaching a supported judgement instead of listing both sides; and executing the exam-craft that carries the marks — correctly labelled diagrams, precise use of the command term, and answers built to the assessment objectives. Content gets you to a 4 or 5. These three lift it to a 7.
All three are trained under the clock in dedicated Economics Drill Sessions — timed, exam-condition practice that runs alongside regular lessons, marked against the real IB criteria.
Evaluation (AO3) is where the top marks live — most visibly in Paper 1's 15-mark part (b) and throughout the IA. We break "discuss both sides" into a repeatable structure students can drill until a balanced judgement becomes a habit, not a guess.
Who is affected — consumers, producers, government, society — and who wins or loses.
Short run vs long run: effects that flip or fade once you extend the horizon.
How big is the effect, and does it actually matter here — size, not just direction.
What has to hold — elasticity, ceteris paribus, rational behaviour — and when it doesn't.
A supported conclusion that answers the actual question, weighted to your strongest point.
A precise, correctly labelled diagram earns analysis marks a paragraph of text can't. These are the ones that recur — drawn cleanly, from memory, under time.
Negative and positive externalities of production and consumption, the welfare loss triangle, and the effect of taxes, subsidies and regulation.
PED/PES on demand-supply, price controls (floors and ceilings), indirect taxes and subsidies, and the incidence between consumer and producer.
Demand-side and supply-side shifts, inflationary and deflationary gaps, and the difference between Keynesian and monetarist/new-classical AS.
Gains from trade, the welfare effect of a tariff or quota, and appreciation/depreciation on a foreign-exchange demand-supply diagram.
For HL students, Paper 3 rewards the quantitative and policy toolkit directly — the calculations, the policy recommendation, the numerical fluency. It's the clearest single place HL marks are won or lost, and the part most worth drilling early rather than cramming. We treat it as its own strand of practice, not an afterthought to the essay papers.
The format table above tells you what you're sitting. This is how the three papers reward different skills — and why a student can be strong on one and weak on another.
One question, two parts — and the marks are lopsided. Part (b) carries the evaluation, and it is where most of the difference between a 5 and a 7 is made.
Rewards precision more than breadth. The text and data are the source of your marks — answers that ignore them and recite theory score poorly however good the theory is.
A different skill entirely — quantitative work and policy recommendation under time. It is the clearest single place HL marks are won or lost, and the most drillable.
Command terms tell you the depth expected. Answering one as if it were another is the most common way a student who knows the content still loses marks.
| Depth | Command terms | What the examiner wants |
|---|---|---|
| Recall | Define · State · List · Outline | The term or points, accurately and briefly. No development needed — and no marks for adding it. |
| Application | Explain · Distinguish · Suggest · Describe | A reason plus its consequence, applied to the context given. One developed point beats three undeveloped ones. |
| Analysis | Analyse · Apply · Comment | A complete cause-and-effect chain with economic reasoning, supported by a correctly labelled diagram where relevant. |
| Evaluation | Discuss · Evaluate · Examine · Justify · To what extent · Compare and contrast | Weigh the argument and reach a supported judgement. This is where the KSAP Evaluation Method does the work. |
| Quantitative & diagram skills | Calculate · Draw · Sketch · Label · Construct · Determine | Accurate working, correct units, fully labelled axes and curves. Heavily weighted in HL Paper 3. |
IB Economics rewards real, current, specific examples — and students at international schools in Singapore are living in one of the best-documented policy laboratories in the world. Generic textbook examples are what every other candidate writes; these are not.
Singapore is one of very few economies that manages monetary policy via the exchange rate rather than interest rates, steering the Singapore dollar against a trade-weighted basket. Explaining why a small, extremely open economy makes that choice is exactly the specific analysis Paper 1 part (b) rewards.
Singapore's carbon tax rose from S$5 per tonne to S$25 in 2024 and to S$45 from 2026 — a clean, dated example of pricing a negative production externality, with a real trajectory you can evaluate on magnitude and effectiveness.
The vehicle quota system sets supply administratively and lets price clear by bidding. It is one of the clearest real illustrations anywhere of a perfectly inelastic supply curve and what happens to price when demand shifts against it.
A broad-based consumption tax, raised in staged steps and paired with offset packages — useful for incidence, regressivity, and evaluating equity against revenue efficiency.
Singapore's dependence on trade, its free-trade agreements and its exposure to supply-chain disruption give concrete grounding for gains from trade, protectionism and the balance of payments.
The Progressive Wage Model and foreign worker levies are a genuinely distinctive alternative to a statutory minimum wage — strong material for evaluating intervention in labour markets.
Examples are only worth marks if they are used, not just named. We build each student a short bank of examples they can actually deploy — the policy, the date, the figure, and the two evaluative points it supports — so that under exam pressure the example arrives complete rather than as a vague reference. Naming a policy earns nothing; using it to support a judgement earns the band.
Three commentaries, 800 words each, marked against IB criteria and moderated externally. It is the only component completed with time, feedback and redrafting available — which makes marks lost here the most avoidable in the whole course. We coach article choice, the criteria that carry the marks, and structured feedback on your own drafts.

IB is a two-year project, and Economics rarely sits in isolation from the rest of it. Three parts of KS Academia Prep exist for exactly that.
Choosing your Diploma subjects — and your HL/SL split — is a bigger, less reversible decision than most families realise, and it shapes which university courses stay open. Our IBDP subject consultation helps you choose a combination that fits your strengths and your targets.
