How IGCSE Economics (0455) is really marked
Economics 0455 has two paper types: the multiple-choice papers (11/12/13) and the structured data-response papers (21/22/23). The syllabus overall is dominated by points-marked content (735 marks) but Papers 21/22/23 add both a calculation component (15 marks total) and a points-with-levels component (60 marks total) — so the structured papers are where marking style genuinely varies within a single question.
On Papers 21/22/23, the earlier parts of a question tend to be points-marked or calculation-marked, asking for a specific figure, definition or identified point from given data. The final parts, usually asking you to discuss or evaluate an economic issue, shift to points-with-levels: the examiner credits both specific economic points made and the overall quality of the developed argument.
The calculation questions, though a small share of the total, are consistently about applying a given formula or percentage correctly to data provided in the question — errors here are typically about which figure to use as the base for a percentage, not about the underlying economic concept.
Where candidates actually lose marks
- In unemployment rate calculations, dividing the number unemployed by the total population rather than by the labour force (the wrong base figure gives a plausible-looking but wrong percentage), and separately, forgetting to multiply by 100 when converting the decimal proportion into a percentage, giving an answer like 0.04 instead of 4%. (try the question)
- Making arithmetic errors when calculating a percentage of a given figure (such as 35% of 790,000), leading to an incorrect final value even when the correct method is used. (try the question)
Command words in IGCSE Economics
| Command word | Times in our bank | What it demands |
|---|---|---|
| Identify | 469 | Name or select the specific economic term, factor or figure the question is asking about, directly from the data or your knowledge. |
| Explain | 90 | Give the economic reasoning that links a cause to an effect, using correct terminology, not just a restatement of the outcome. |
| Discuss | 90 | Consider more than one side of an economic issue and develop a reasoned response — this is points-with-levels, so both specific points and overall argument quality are credited. |
| Analyse | 79 | Break down an economic issue into its component effects or causes, showing chains of reasoning rather than a single-step answer. |
| Calculate | 44 | Work out a numerical value from the data given, using the correct formula and base figure, and show your working. |
| Define | 20 | Give the precise economic meaning of a term, in the standard way it's used in the syllabus. |
| Draw | 10 | Produce an accurate economic diagram (such as a demand or supply curve) with correctly labelled axes and curves. |
| Deduce | 7 | Use the data given in the question to work out a conclusion that isn't stated directly. |
How to revise with past papers
Because the calculation questions in this syllabus are small in number but recur in a predictable pattern — percentage-of-a-figure and rate calculations using a specific base — past-paper practice should include deliberately checking which base figure a calculation should use (labour force versus total population, for instance) before doing the arithmetic.
For the Discuss and Analyse questions on Papers 21/22/23, practise developing a chain of reasoning rather than stating several disconnected economic effects — since these parts are points-with-levels, a shorter but well-linked argument tends to do better than a longer list of separate points.
This is general advice but useful here: always show your working on calculation questions, even simple ones, since method marks may be available and it makes it easier to catch a wrong-base error (like using population instead of labour force) before it costs the whole answer.

Is Economics 0455 mostly multiple-choice or written answers?
Both papers matter: Papers 11/12/13 are multiple-choice, and Papers 21/22/23 are structured data-response papers combining points-marked, calculation and points-with-levels content.
What's the most common calculation mistake in this subject?
Using the wrong base figure for a rate or percentage calculation — for example dividing by total population instead of the labour force when calculating an unemployment rate.
How are the Discuss and Analyse parts of Paper 2 marked?
As points-with-levels: the mark scheme credits specific economic points made, but the overall quality and development of the argument also affects the mark.
Do I need to show working for Calculate questions?
Yes — showing the formula and base figure used makes it easier to identify (and avoid) errors like using the wrong denominator in a percentage calculation.
