OCR A-Level grade boundary FAQs

- When are OCR grade boundaries published?
- Exam boards publish grade boundaries on results day, once every paper has been marked and grading is complete. A-Level boundaries appear in mid August and GCSE boundaries the week after.
- Why do grade boundaries change every year?
- Boundaries are set after each exam series so that grading standards stay consistent from year to year. If a paper turns out harder than usual the boundaries come down, and if it turns out easier they go up, so the marks needed for a grade reflect the difficulty of that year's papers.
- Are grade boundaries the same for every exam board?
- No. AQA, Edexcel, OCR and WJEC each set boundaries for their own papers, so the marks needed for the same grade differ between boards and between specifications within a board. Always check the boundaries for the exact specification you sat.
