How to get a 7 in IB Economics

Know exactly what you are being graded on

It still surprises me how many students sit their first mock without knowing the mark allocations. Everything in the course comes from four units — introduction to economics, microeconomics, macroeconomics, and the global economy — and it is assessed like this (current syllabus, first assessment 2022):

• Paper 1rewards structure from memory: define, draw, explain the chain of reasoning, then genuinely evaluate in part (b) — with real-world examples.
• Paper 2 rewards application: reading unseen data fast and connecting it to the right model without padding.
• Paper 3rewards calculation accuracy plus judgement — each question ends by asking you to recommend a policy and defend it.
• The IA rewards patience. It is the only component you can redraft, which is why I treat it separately below.

Diagram fluency: the highest-ROI skill

Every tutoring blog tells you to “draw good diagrams.” That advice is useless without a list. Here is mine. Roughly fifteen core diagrams cover the large majority of questions you will ever face:

• Markets:supply and demand with shifts in either curve, and elasticity comparisons — a steep curve next to a flat one, because that contrast drives half the analysis in the course.
• Intervention: an indirect tax and a subsidy (with the incidence areas shaded), a price ceiling, and a price floor.
• Market failure:all four externality diagrams — negative and positive, production and consumption. Examiners punish students who can only draw the negative production version.
• Firms (HL): monopoly versus perfect competition, including the welfare loss from market power.
• Macro: aggregate demand and aggregate supply in the short run and the long run, including the Keynesian flat-section version, plus the Phillips curve at HL.
• Global economy: the exchange rate market (a currency priced in another currency) and the tariff diagram with its welfare areas.

The standard to hit: any of these from memory in under a minute, fully labelled — axes in words, every curve named, equilibria marked, arrows showing the shift, areas shaded where the question needs them. Speed matters because Paper 1 gives you 75 minutes for a two-part essay. A diagram that takes five minutes steals time from your evaluation.

The training method is blank-page recall, not copying. Close the textbook. Take an empty page. Draw the negative consumption externality diagram from memory. Then open the book and mark your own attempt like an examiner. Redraw whatever you missed. Copying a diagram feels productive and trains almost nothing; recalling one is uncomfortable and trains exactly the skill the exam tests. To check your understanding alongside the drawing, work through the free problem sets on supply and demand, price ceilings and floors, and aggregate demand and supply — no signup needed — and use the explainer library when a model refuses to stick.

Evaluation is a skill, not a vibe

The command terms that decide your grade — discuss, evaluate, justify— sit at the top of the assessment objectives (the IB calls this level AO3). They do not ask you to describe a policy and then add “however, there are also disadvantages.” They ask you to weigh. In practice an examiner is looking for four moves: short run against long run, the stakeholders who win against those who lose, the “depends-on” factors (elasticity, the size of the change, the state of the economy), and a conclusion you actually defend.

Here is what that looks like for a classic part (b): evaluating a tax on sugary drinks.

You will meet acronym frameworks like CLASPP (conclusions, long run versus short run, assumptions, stakeholders, priorities, pros and cons). Used honestly, they are a decent pre-flight checklist. But examiners reward judgement, not acronym recitation. An essay that mechanically ticks six boxes reads worse than one that picks the two most relevant tensions and argues them properly.

Structuring the Paper 1 essay

Paper 1 gives you 75 minutes for one two-part essay, and the parts reward different things. Treat them as two different tasks, not one long one.

Part (a), 10 marks, roughly 25–30 minutes. This part rewards explanation: define the key terms in the question, draw the relevant diagram fully labeled, and walk through the mechanism step by step — what shifts, why it shifts, and what happens to the equilibrium. A short real-world example strengthens the explanation. No evaluation is needed here; spending part (a) time on “however” paragraphs is spending it where the mark scheme cannot pay you.

Part (b), 15 marks, roughly 40–45 minutes. This is the evaluation question — the command term will be discuss, evaluate, or justify. Structure that scores: a brief setup of the theory (faster than part (a), since you earn marks for judgment here, not re-explanation), a diagram where it adds force, a prepared real-world example with a number and a date, then the four evaluation moves from the section above — time horizon, stakeholders, depends-on factors, and a conclusion you actually defend.

Two habits separate 7-band essays. First, spend three minutes planning before writing anything — choose the diagram, the example, and your conclusion up front, so the essay argues toward something instead of wandering. Second, answer the exact question asked, in its own words, in your first and last paragraphs. Examiners mark dozens of scripts that recite everything the student knows about the topic; the scripts that stand out are the ones that noticed what was actually asked.

Real-world examples: prepare them before exam season

The current syllabus expects real-world examples in your extended responses, and this is where most students bleed marks. Writing “for example, a country like the USA” earns nothing. An example only carries weight when it has a name, a number, and a date — and you will not produce those under exam pressure unless you banked them earlier.

So keep a running example bank: one prepared example per syllabus topic, each with a specific figure and a year, reviewed alongside your definitions. A few evergreen categories that map cleanly onto exam questions:

• A sugar or soft-drinks tax— the United Kingdom's soft drinks levy, in force since 2018, fits externalities, indirect taxes, and elasticity questions at once.
• A minimum wage changein any country you follow — perfect for price floors and labour market questions.
• A central bank tightening cycle— the 2022–2023 interest rate rises that major central banks used against inflation cover monetary policy and the AD/AS model.
• A tariff episode— the US–China tariffs that began in 2018 work for protectionism, tariff diagrams, and trade policy evaluation.
• A sharp currency depreciationin a country you can name — useful for exchange rates, import prices, and the balance of payments.

Five well-rehearsed examples, each usable across several question types, beat thirty half-remembered headlines.

The IA: banked marks you control

The internal assessment is a portfolio of three commentaries, each a maximum of 800 words, each analysing a different published news article, and each drawn from a different unit of the syllabus. It is worth 30 percent of the final grade at SL and 20 percent at HL. Diagrams and references sit outside the word count, so the 800 words are pure analysis.

Here is the strategic point students miss: the IA is the one component with effectively unlimited drafting time. Exam papers punish a bad morning; the IA does not. Treat it as marks you bank before exam season starts. Two practical rules. First, choose articles that map cleanly onto a single diagram — a news story about a fuel subsidy is a gift; a story about five overlapping policies is a trap. Second, finish your final commentary well before the deadline crush, when your other subjects will be demanding the same weeks.

A realistic weekly system

You have five other subjects, theory of knowledge, and an extended essay. Any plan that assumes economics gets ten hours a week is fiction. Fortunately, the evidence on learning says you do not need ten hours — you need short, frequent retrieval. Two focused sessions per week beat one long Sunday re-read, because re-reading feels fluent while testing yourself actually builds recall. (The research behind this is summarised on our learning science page.)

• Session one (25 minutes, midweek):blank-page diagram recall. Pick three diagrams — two from the current topic, one from an older topic — draw them from memory, mark your own work, redraw the misses.
• Session two (25 minutes, weekend): ten practice questions, mixing the current topic with older ones so nothing decays.
• Definitions: put every term of art into a spaced repetition deck and clear it in five minutes a day. Definition marks are the cheapest marks on the paper; losing them is self-inflicted.
• From about three months out:add past-paper questions under real time pressure — a full 25-mark Paper 1 essay in 75 minutes, then a marked Paper 2 data response. Timing is a skill, and the first timed essay is always a shock. Make sure the shock happens in your bedroom, not the exam hall.

That is roughly 90 minutes a week plus daily flashcard scraps. It is sustainable for eighteen months, which is precisely why it works.

Frequently asked questions

What percentage is a 7 in IB Economics?

There is no fixed percentage. The IB sets grade boundaries fresh each session, and they vary by level and timezone. In recent sessions a 7 has typically required somewhere roughly in the low 70s to low 80s as a percentage of total marks. Your IB coordinator can show you the exact boundaries from the most recent session. The practical takeaway: aim to perform comfortably above 80 percent in mocks so that a bad day still lands inside the 7 band.

Is IB Economics hard?

The content itself is approachable — there is no calculus, and most of it is structured logical reasoning. What makes the subject hard is the skill standard: drawing accurate, fully labelled diagrams quickly, evaluating rather than describing, and supporting arguments with specific real-world examples. Students who treat it as a memorisation subject struggle. Students who train those three skills deliberately find it very learnable.

How many diagrams are in IB Economics?

The syllabus gives no official count, but roughly 12 to 15 core diagrams cover the large majority of exam questions: supply and demand with shifts, elasticity comparisons, tax and subsidy incidence, price ceilings and floors, the four externality diagrams, monopoly versus perfect competition (HL), aggregate demand and aggregate supply in the short and long run, the Phillips curve (HL), the exchange rate market, and the tariff diagram. Most other diagrams in the course are variations on these.

Is IB Economics SL or HL harder?

HL is more demanding. Both levels share the same four units, but HL adds extension topics, more teaching hours, and Paper 3 — a quantitative policy paper that SL students never sit. HL also weights the internal assessment less (20 percent versus 30 percent at SL), so more of an HL grade rides on exam-day performance.

How long should an IB Economics IA be?

Each of the three commentaries has a maximum of 800 words, and diagrams, labels and references sit outside the word count. The full portfolio must cover three different units of the syllabus, with each commentary analysing a different published news article through one of the course's key concepts.

How do you structure an IB Economics essay?

Treat the two parts of a Paper 1 essay as separate tasks. Part (a), 10 marks: define the key terms, draw a fully labelled diagram, and explain the mechanism step by step — pure explanation, no evaluation. Part (b), 15 marks: a brief theory setup, a diagram where it helps, a specific real-world example, and then genuine evaluation — short run versus long run, winners versus losers, what the outcome depends on, and a defended conclusion. Plan for three minutes before writing, and answer the exact question asked rather than reciting the topic.

Do you need math for IB Economics?

Not much. SL needs arithmetic, percentages and the ability to read graphs. HL adds Paper 3 calculations — elasticities, linear demand and supply equations, and similar policy arithmetic — but nothing beyond comfortable algebra. There is no calculus anywhere in IB Economics.
