Predict Your GCSE Grades
Enter your mock exam scores to see predicted GCSE grades. Find out where you stand and how much improvement could boost your results. Already know your marks? Use our grade calculator for exam-board-specific boundaries.
Estimate Only: These predictions use approximate grade boundaries. Actual boundaries vary by exam board, subject, and year. Foundation tier is capped at Grade 5.
How GCSE Grade Prediction Works
This tool maps your mock exam percentage to the standard GCSE 9-1 grading scale using approximate grade boundaries. While actual boundaries vary by exam board and year, mock exam scores are a strong indicator of final performance.
Understanding Foundation vs Higher Tier
Most GCSE subjects offer two tiers of entry. Higher tier covers grades 4-9, while Foundation tier covers grades 1-5. If you're taking Foundation, the maximum grade you can achieve is 5 — even with a perfect score. This tool applies the Foundation cap automatically.
Approximate Grade Boundaries
| Percentage | Grade | Description |
|---|---|---|
| 90-100% | 9 | Exceptional |
| 80-89% | 8 | Outstanding |
| 70-79% | 7 | Excellent |
| 60-69% | 6 | Strong |
| 50-59% | 5 | Good (Strong Pass) |
| 40-49% | 4 | Standard Pass |
| 30-39% | 3 | Below Pass |
| 20-29% | 2 | Basic |
| 0-19% | 1 | Limited |
Tips for Improving Your Mock Scores
- Focus revision on your weakest topics first — the biggest gains come from closing gaps
- Practise past papers under timed conditions to build exam technique
- Use active recall (self-testing) instead of passive re-reading
- A tutor can identify specific weak areas and create a targeted study plan
Disclaimer: These predictions are estimates based on typical grade boundaries. Actual boundaries vary by exam board and year. Mock exam performance is a useful indicator but does not guarantee final results. For the most accurate prediction, consult your school or exam board.
Frequently asked questions
How accurate is the GCSE grade predictor?
The predictor uses historical grade boundaries published by the major UK exam boards (AQA, Edexcel, OCR) to convert a raw mock percentage into an indicative grade. It is a guide, not a guarantee — actual GCSE grade boundaries shift each year based on cohort performance.
What does each GCSE grade mean?
GCSE grades run from 9 (the highest) down to 1 (the lowest). Grade 4 is a standard pass, grade 5 is a strong pass, and grade 7 is equivalent to the old A grade. Grades 8 and 9 are above the old A*.
Can this predictor tell me my final GCSE grade?
No — no tool can predict a final grade with certainty. Mock results indicate current standing, but children typically improve between mocks and the real exam with focused revision. Use the predictor as a starting point, not a final verdict.
Why is my predicted grade different from my school's?
Schools set predicted grades from everything they see — classwork, effort, coursework and more than one mock — and often deliberately set a stretching target. This tool only converts one raw mock percentage using published boundaries, so treat a gap as a prompt to ask your teacher what they are weighing, not as a contradiction.
What is the difference between a predicted grade and a target grade?
A predicted grade is what you are on course for now. A target grade is what the school believes you can reach with the right work, and is usually higher. UCAS and sixth-form applications use predicted grades, which is why the gap between the two matters in Year 11.
