Grade Boundaries

AQA, OCR, Edexcel and Cambridge IGCSE — see exactly how many marks you need for each grade.

⚠️ Disclaimer: Grade boundaries vary each year. Data below is from 2025 for reference. Always check the official exam board websites for the most current boundaries.

What does this mean?

Grade boundaries are the minimum marks needed to achieve each grade. They are set after each exam series based on student performance. A grade 9 boundary of 107 means you need at least 107/160 marks to achieve a grade 9. Boundaries change each year, so use these figures as a guide only.
