0455_m26_ms_12 — 2026 March Economics 0455 Mark Scheme 1 Variant 2 · Cambridge CAIE IGCSE

This is the official Cambridge mark scheme for Economics (0455) Mark Scheme 1 (Variant 2) from the 2026 March session. Mark schemes show exactly how each mark is awarded, including acceptable alternative answers, required key terms, and common errors that lose marks. Cambridge mark schemes use notation like "allow," "accept," and "do not credit" to define the boundary between full marks and zero.

Paper 1: Multiple Choice — This is Paper 1: Multiple Choice, worth 30 marks with a duration of 45m. 30 multiple choice questions covering the full syllabus. Common traps involve confusing similar concepts (PED vs PES, elastic vs inelastic, shifts vs movements).

This mark scheme corresponds to 0455_m26_qp_12. For maximum revision benefit, attempt the question paper under strict exam conditions first, then use this mark scheme to self-assess. Pay attention to the marking notation: "allow" means an alternative is accepted, "do not credit" means a specific phrasing is rejected even if technically correct, and "ORA" (or reverse argument) means the mark can also be earned with the opposite reasoning.

Cambridge mark schemes reward precise language. For Economics (0455), look for keywords the examiner requires — definitions must include specific terms (e.g., "per unit mass," "resultant"), and calculations must show working even if the final answer is correct. Understanding mark scheme conventions helps you write answers that hit every marking point, not just the general idea.
