The raw marks students needed for each grade, the percentage achieving each grade, and how they have changed since 2022. All figures are tutor2u’s analysis of the official OCR data.
Figures are for OCR’s largest specification, OCR Chemistry A — OCR offers this subject as more than one specification with different papers and boundaries. Why do these change? →

Reading 2022? 2022 was an exceptional, transitional year for grading - positioned roughly midway between the more generous 2021 arrangements and pre-pandemic (2019) standards. Treat 2022→2023 changes with caution rather than as a normal year-on-year trend.
