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.

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 tiercovers 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
