The checklist
IGCSE Math Revision: calculator checklist for exam day
- The right paper. Cambridge 0580: no calculator in Papers 1 and 2, a scientific calculator in Papers 3 and 4. Edexcel 4MA1: a calculator in every paper. IGCSE calculator rules.
- Clear the memory. Cambridge asks you to clear the memory before and after the exam: how to reset it.
- Batteries. Fresh batteries. Cambridge lets you bring a spare set in transparent packaging.
- Degrees. IGCSE uses degrees: if the screen shows R or Rad, switch it back.
- Exact or decimal. Know the key that switches a fraction to a decimal: fractions and decimals.
- Nothing on it. Cambridge: no calculator case, instruction leaflet, or instructions or formulae on the lid or cover.
- If it shows an error. Know what Math ERROR means: error messages explained.
Rules from: Cambridge Handbook 2026, section 5.1.7.1 Calculators (PDF) · Cambridge IGCSE Mathematics 0580 syllabus 2025–2027 (PDF) · Pearson Edexcel International GCSE Mathematics A (4MA1) specification, Issue 2 (PDF)

Every keystroke on this page comes from the manufacturer's own guide for that model, and every exam rule from the exam board's own document; each section names its source. Where we could not find a step in one of those documents, we have left it out. IGCSE Math Revision is independent and is not connected to Casio, Texas Instruments or any exam board.
