Exam Skills
Master the NSC Economics exam format — command words, essay structure, diagram technique and paper layout. Understanding these skills is worth as many marks as knowing the content.
💬 Command Words — What the Examiner Wants
The most common mistake in NSC Economics: students who know the content but answer the wrong question — they "explain" when the question says "evaluate", or "list" when it says "discuss". Each command word demands a specific response structure. The marks are in the structure, not just the facts.
Define / What is meant by
Give the precise meaning of a term
One or two clear sentences. Use key economic terminology. No examples required unless asked. No introduction or conclusion needed.
Typically 2 marks · 1 mark per key element of the definition
Explain / Describe
Give reasons or show how something works
Define the concept first, then explain the mechanism or process step by step. Use linking words: "because", "therefore", "this leads to", "as a result". Each logical step earns a mark.
Typically 4–6 marks · 1–2 marks per explained point
Distinguish / Differentiate
Show how two concepts differ
Define both concepts. Then explicitly compare them using a contrast word: "whereas", "unlike", "in contrast". A table format works well. Never define only one side.
Typically 4–6 marks · marks for each side + the comparison
Discuss
Examine a topic by presenting multiple relevant points
Introduction (define the key concept). Body: present several distinct points — each in its own paragraph with explanation. These can be causes, effects, advantages, or factors. Conclusion: brief summary. No need to argue for or against.
Typically 6–8 marks · 2 marks per well-explained point
Evaluate
Make a judgement — weigh up strengths and weaknesses
Introduction (state the issue and your overall position). Body: present both sides — positive effects AND limitations/criticisms. Each side needs explanation and evidence. Conclusion: give a definitive judgement — which side outweighs the other, and why. "Evaluate" always requires a conclusion with a clear stance.
Typically 8–10 marks · marks for both sides + quality conclusion
Assess
Determine the value or significance of something
Very similar to "evaluate" — make a judgement about extent, importance or effectiveness. Requires: evidence for + evidence against + a measured conclusion. Often used with "to what extent" — answer must give a direct response ("to a large/limited/moderate extent, because...").
Typically 8–10 marks · same structure as evaluate
Calculate
Work out a numerical answer using a formula
Write the formula first. Substitute the values with units. Show each step of working — marks are awarded for method even if the final answer is wrong. State the unit in your answer (%, R, times).
Typically 2–4 marks · 1 mark for formula, marks for working and answer
Use a diagram / Draw and explain
Illustrate your answer with a correctly labelled diagram
Draw neatly with a ruler. Label ALL axes, curves and equilibrium points. Show the change (shift) with an arrow. Reference the diagram in your written answer: "As shown in the diagram, the supply curve shifts left from S1 to S2..." Never draw a diagram without explaining it in words.
Typically 4–6 marks for diagram · marks for axes, curves, labels, shift, new equilibrium
📝 Essay Structure by Mark Allocation
The NSC marking guideline allocates marks by paragraph, not by essay. The examiner works through your answer line by line ticking mark-earning statements. Every paragraph should earn marks independently. An introduction that just restates the question earns zero marks — it must define key terms or state the context.
Template — 4 Mark "Explain" Question4 marks
1
Define the key concept (1–2 marks)
Give a precise definition using economic terminology. This earns marks immediately. Example: "A budget deficit occurs when government expenditure (G) exceeds tax revenue (T), i.e. G > T."
2
Explain the mechanism (2–3 marks)
Describe HOW it works step by step, using linking words. "When the government spends more than it earns, it must borrow by issuing government bonds. This increases demand for loanable funds, which pushes interest rates up..."
Template — 8 Mark "Discuss" Question8 marks
1
Introduction — define and contextualise (1–2 marks)
Define the key concept. State what you are going to discuss. Do NOT just restate the question — the definition earns marks.
2
Point 1 — explain fully (2 marks)
State the point clearly. Explain it with a reason or mechanism. Add a South African example where possible. Aim for 3–4 sentences per point.
3
Point 2 — explain fully (2 marks)
A second distinct point — not a rewording of Point 1. Use a new paragraph. Same structure: state → explain → example.
4
Point 3 — explain fully (2 marks)
Third point. If you run out of distinct points, go deeper on earlier points with more explanation or a different angle.
5
Conclusion — summarise (1 mark)
One or two sentences that bring the discussion together. Do NOT introduce new points. "In conclusion, [topic] affects the economy through [summary of main points]."
Template — 10 Mark "Evaluate" Question10 marks
1
Introduction — define, contextualise, state your position (1–2 marks)
Define the key concept. Briefly state both sides exist. You may state your overall position upfront: "While X has benefits, its limitations mean it is only partially effective."
2
Arguments IN FAVOUR (positive/benefits) (3–4 marks)
2–3 distinct positive points, each explained and evidenced. Use SA data where possible. "Expansionary fiscal policy creates jobs directly — infrastructure spending employs construction workers and generates a multiplier effect..."
3
Arguments AGAINST (limitations/criticisms) (3–4 marks)
2–3 distinct limitations, each explained. "However, fiscal policy in SA is constrained by a debt-to-GDP ratio of ~75%, limiting borrowing capacity. Furthermore, implementation lags mean stimulus may arrive after the recession ends..."
4
Evaluative conclusion — your definitive judgement (2 marks)
This is where "evaluate" earns its extra marks over "discuss". Give a clear verdict: "On balance, X is effective/limited because [most compelling reason]. It would be more effective if [condition]." A conclusion that just summarises without a verdict earns 0–1 marks.
📊 The CAPS Marking Rubric
NSC Economics does not have a single holistic rubric — it marks each point discretely. However, the DBE marking guidelines follow consistent patterns. Understanding these patterns helps you write answers that align with how examiners allocate marks.
| Question Type | Marks | What earns marks | Common mistakes |
|---|---|---|---|
| Definition / "What is meant by" | 2 | Each key element of the definition (usually 2 elements = 2 marks) | Circular definitions ("inflation is when prices inflate"); missing units or direction |
| Short explanation | 4 | Definition (1–2) + mechanism explained step by step (2–3) | Stating facts without explaining the causal chain; stopping after the definition |
| Discuss / Explain with points | 8 | Introduction with definition (2) + 3 explained points (2 each) + conclusion (1–2) | Bullet-point lists without explanation; repeating the same point in different words; no conclusion |
| Evaluate / Assess | 10 | Introduction (2) + pros (3–4) + cons (3–4) + evaluative conclusion with verdict (2) | Only one side (all pros or all cons); conclusion that summarises instead of judging; no verdict |
| Diagram question | 4–6 | Correct axes (1) + correctly drawn curves (1–2) + labels & equilibrium (1) + shift with arrow (1) + new equilibrium (1) | Unlabelled axes; missing original equilibrium; no arrow showing direction of shift; drawing without explaining in text |
| Data response (Section B) | 30–40 | Reading data correctly (1–2) + explaining trends with economic concepts (2 per point) + applying theory to stimulus (2 per point) | Describing the graph without explaining why; ignoring data and writing generic theory; not quoting figures from the stimulus |
📈 Diagram Technique
A diagram without an explanation earns partial marks. An explanation without a diagram (when one is asked for) loses diagram marks entirely. Every NSC diagram question requires both the drawing AND a written explanation that references the diagram explicitly.
Always label both axes with words, not just letters
Write "Price (R)" on the y-axis and "Quantity (units)" on the x-axis. Unlabelled axes lose 1 mark. "P" and "Q" alone are insufficient unless you define them.
Show the original position before the change
Always draw the initial equilibrium (P1, Q1) before showing any shift. The examiner needs to see BOTH positions to award full marks for the shift question.
Use arrows to show the direction of the shift
When drawing a shifted curve (S1 → S2, D1 → D2), draw a clear arrow showing the direction. Write S2 or D2 at the end of the new curve. A shift without direction loses the "shift" mark.
Mark the new equilibrium with dotted lines
Draw dotted lines from the new intersection point down to the x-axis (Q2) and across to the y-axis (P2). Label them. This is worth 1 mark and is the most commonly missed mark in diagram questions.
Reference the diagram explicitly in your written answer
Do not draw a diagram and then write a separate explanation that ignores it. Instead: "As shown in the diagram, an increase in input costs shifts the supply curve LEFT from S1 to S2. At the original price P1 there is now a shortage, causing price to rise to the new equilibrium P2, with quantity falling from Q1 to Q2."
Know which diagram fits which question
Supply & demand: any market price/quantity question. Negative externality: pollution, carbon emissions questions. Monopoly (AR/MR/MC/AC): market power questions. Lorenz curve: inequality questions. Business cycle curve: phases of the cycle. PPC: opportunity cost, economic growth questions.

Paper 2 — Development Economics
2 hours · 150 marks
Section A (30 marks): Multiple choice & matching. 1 mark each. Spend max 25 min.
Section B (60 marks): Data response — 3 questions. Economic data, graphs and extracts. Quote from stimulus. 40 min.
Section C (60 marks): Choose 3 of 4 essays. Same structure as Paper 1. 55 min.
Time per mark: ~0.8 minutes
| Exam priority | Strategy |
|---|---|
| Section A first | Do multiple choice first — easiest marks, builds confidence. If stuck, eliminate 2 wrong options and choose between the remaining 2. Never leave blank. |
| Section B — read stimulus twice | First read: understand what the data shows. Second read: identify which concept is being tested. Every answer must reference figures from the data ("According to Figure 1, GDP fell by 2.3% in Q3..."). |
| Section C — plan before you write | Spend 2 minutes listing your main points before writing. This prevents repetition and ensures you cover both sides of an evaluate question. Choose the essay topic you know best, not the one that sounds easiest. |
| South African examples | Always use SA-specific examples (Eskom, SARB, SARS, JSE, Gini coefficient, NDP 2030). Generic examples score marks but SA examples demonstrate deeper understanding and often unlock the top mark. |
| Definitions earn marks | Start every essay body paragraph with a definition of the key concept being discussed. Even in an 8-mark essay, defining each term as you introduce it earns 1–2 easy marks that many students miss. |
