What are grade boundaries?
For Cambridge syllabus 0580, grade boundaries are the minimum raw marks Cambridge requires for each letter grade on each component of 0580 Mathematics. They are not fixed percentages — your overall IGCSE grade uses the weighted sum of the papers you entered (for example Extended route components 22 + 42). Each paper variant (11, 12, 21, etc.) has its own threshold row in the official PDF, so always match your exact component code before comparing marks.
How Cambridge sets 0580 boundaries
For Cambridge syllabus 0580, cambridge sets 0580 thresholds after all scripts are marked, using comparable outcomes so a grade A* means the same standard every year. If an Extended Paper 4 is unusually demanding, the aggregate boundary typically falls — students often misread this as "everyone failed" when the standard was simply harder. A* is awarded only on the syllabus aggregate, not on a single component sitting at A* raw marks alone.
