2025 Cambridge IGCSE Mathematics (0580) Past Paper 分析與預測
A comprehensive analysis of the May/June 2025 Cambridge IGCSE Mathematics (0580) series (covering papers 12, 22, 32, and 42). The series features balanced difficulty, testing non-calculator core arithmetic alongside sophisticated multi-step algebra, coordinate geometry, and 3D trigonometry.

考官重點
官方報告整理常見失分位
- Specifying multiple distinct transformations (e.g. rotation followed by reflection) when a single transformation is explicitly required.
- Rounding intermediate steps to 3 significant figures in non-right-angled trigonometry, causing inaccurate final values.
- Omitting the straight boundaries (diameters) when calculating the total perimeter of a compound shape made of semicircles.
常見誤解
- Treating fractional negative exponents (like 2^-3) as negative integers (e.g. -8) or incorrectly taking the reciprocal as a product fraction (e.g. 1/6).
- Believing that limits of accuracy bounds always involve decimal additions (like adding 0.5 or 0.05) rather than checking the measurement unit's precision.
失分原因
- In the non-calculator papers, fraction divisions and basic factor trees for HCF caused high error rates among core-level candidates.
- In the cumulative frequency question, reading errors and drawing straight lines instead of a smooth S-curve resulted in significant point loss.
- Establishing correct algebraic fractions from speed-distance-time word problems proved difficult for those unable to structure a single unified quadratic equation.
