GCSE Grade Calculator
Enter your paper marks and the published boundary table to estimate a GCSE grade from 9 to 1.
Grade boundaries
Enter percentage boundaries for the exact board, specification, tier, and exam series. Convert published raw-mark boundaries to percentages before entering them.
GCSE board, subject, and tier matter
AQA, Edexcel, OCR, and WJEC Eduqas can use different papers and boundaries. Mathematics, sciences, and languages may also have foundation and higher tiers.
Why GCSE boundaries change
Exam boards review how students performed and how difficult the papers were before setting boundaries. A higher boundary does not automatically mean the qualification became harder.

Common questions
How do I estimate my GCSE grade?
Combine your scaled paper marks, calculate the qualification percentage, and compare it with the published grade boundaries for your board, specification, tier, and exam series.
What do GCSE grades 9 to 1 mean?
Grade 9 is the highest grade. Grade 4 is commonly described as a standard pass and grade 5 as a strong pass, although schools and courses set their own requirements.
Are foundation and higher tier boundaries different?
Yes. Tiered subjects have different available grade ranges and boundary tables. Use the table matching the tier you sat.
Can GCSE boundaries be predicted before results day?
Not exactly. Final boundaries are set after exams are marked, so past tables are only practice references.
