About What Do I Need?
Why the GCSE and A-level calculator exists, which qualifications it covers and how the data is checked.
Use What Do I Need? to check GCSE and A-level marks against published AQA, OCR and Pearson Edexcel grade boundaries.
Choose the exact specification and entry option. Paper calculators use verified component structures. Total-mark checkers are labelled separately and need the qualification total on the published boundary scale. Every result links to its official source.
You can also compare boundary percentages, test the same percentage across subjects, play a guessing game or inspect the frozen 2027 forecast. The comparisons describe published thresholds; the forecasts are speculative.
The site is independent of AQA, OCR, Pearson Edexcel and the Joint Council for Qualifications. Awarding organisations remain the authority for specifications, results and confirmed boundaries.
