A percentage makes tests with different total marks easier to compare.
Boundary caution
Exam boards publish official boundaries after an exam series, so mock boundaries are usually only an approximation.
UK grading disclaimer
This calculator is for general planning and education only. UK grades are not GPA. Actual GCSE, A-Level, degree, and UCAS outcomes depend on exam boards, universities, course rules, moderation, weighting, grade boundaries, and official published requirements.
- GCSE and A-Level boundaries are set after each exam series.
- Universities can use weighting, best-credit, compensation, or borderline rules.
- UCAS points do not guarantee entry; course requirements vary.
Frequently asked questions
Is this a UK calculator?
Yes. These calculators use UK-style GCSE, A-Level, degree classification, and UCAS concepts rather than US GPA.
Are the grade boundaries official?
No. They are approximate planning guides. Always check your exam board, school, university, or UCAS course page.
Can this predict my final official grade?
It can estimate from the data entered, but official results depend on marking, moderation, boundaries, and institutional rules.
Why do weights matter?
A high mark in a heavily weighted exam affects the overall grade more than the same mark in a lightly weighted assessment.
Does this use GPA?
No. GPA is not used for these UK-focused grade calculators.
