About this calculator
The A-Level Grade Calculator estimates A-Level grades from percentage marks. It is useful for mock exams, practice papers, and planning, while recognising that many A-Levels are linear and grade boundaries vary each year.
A-Level grade calculator method
The calculator converts marks to an overall percentage and maps the result to an approximate A*-E boundary guide.
- percentage = marks / total marks x 100
- A* = 90%+, A = 80%+, B = 70%+, C = 60%+, D = 50%+, E = 40%+
How to use the a-level grade calculator
- Enter component or paper marks.
- Enter total marks and weightings.
- Calculate weighted percentage.
- Compare with the A-Level grade guide.
- Check exam board boundaries for the real grade.
Worked examples
Mock result
Input: 72%
Calculation: Compare with A-Level guide
Result: Approximate B guide
Borderline A
Input: 79%
Calculation: Close to 80% guide
Result: Borderline A guide, depending on official boundary
A-Level grade bands
A-Level grades run from A* to E, with U for ungraded. Official boundaries can vary significantly by paper and subject.
Linear A-Levels
Many A-Levels are assessed at the end of the course, so internal weighting may not match final exam-board calculations.
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.
