IGCSE Exam Coach — Explanation

Practice for Cambridge IGCSE Economics (0455) Paper 2, in its 2027 form: 2 hours, 80 marks. Section A is one compulsory question on a real economy, with data (20 marks); in Section B you answer three of four questions, each worth 20 marks: (a) 2, (b) 4, (c) 6, (d) 8.

Choose a question and work through its parts. For each part:

  1. Decode it. What does the command word ask for, and what do the marks tell you? Define wants two parts of a definition; Explain two wants two points, each identified and explained; Analyse wants chains of reasoning (naming points earns at most half the marks); Discuss wants both sides.
  2. Build your answer from sentences, in order. Some don’t belong: they’re the mistakes examiners see most, such as reversing an argument instead of giving the other side, or a conclusion that only summarises.
  3. Check it against the mark scheme’s points. The 8-mark Discuss is marked in levels: both sides developed reach Level 3.
  4. See a model answer and what the examiners advise.
  5. If you like, write it in your own words and mark it yourself against the same points or levels: the computer doesn’t mark what you type.

Your first check of each part is your mark; you can check again as often as you like. Past-paper questions are Cambridge’s own, with answers built from their published mark schemes; the others are original questions in the same style, with illustrative figures.

Objective: Cambridge IGCSE Economics 0455 (2027–2029), Paper 2, structured and data response questions: the command words (define, identify, calculate, explain, analyse, discuss) and how each is marked, demand and supply diagrams, analysing relationships in data, and two-sided discussion.

On the te reo Māori column. Terms marked as gaps have no attested equivalent in the sources checked — Karaitiana Taiuru's Dictionary of Māori Computer and Social Media Terms, Paekupu, the Reserve Bank's te reo financial glossary, NZQA and Te Aka. No coinage is printed as though it were established; where a class needs one, commission it from Te Taura Whiri i te Reo Māori and credit the translator. Te reo Māori is not italicised and takes no plural "s".
