IGCSE Subject Codes: Cambridge & Edexcel Reference

When you register for IGCSE, you need the correct syllabus and option codes so the centre enters you for the right exam (e.g. Core vs Extended, or alternative to coursework).

Why Codes Matter

• Each subject and variant (e.g. Mathematics – Core 0580, Extended 0580) has a syllabus code.
• Option codes can indicate tier (Core/Extended), component (e.g. Paper 2, Paper 4), or variant (e.g. alternative to practical).
• Wrong code = wrong paper or no result.

Where to Find Codes

• Cambridge: Cambridge website → IGCSE → your subject → “syllabus overview” or “options” for codes.
• Edexcel: Pearson website → International GCSE → subject → specification and entry codes.
• Your exam centre will also have the current list and can confirm which codes they offer.

Common Examples

• Cambridge Mathematics: 0580 (Core and Extended options within same syllabus).
• Cambridge English First Language: 0500 (with coursework or alternative to coursework).
• Sciences: Check whether you’re entering alternative to practical (specific component code).

Always double-check with your centre before they submit your entry.
