What it does
Every June OCR A-level Chemistry grade boundary from 2017 to 2026 as a percentage, and the 2027 exam dates.
OCR A-level Chemistry: the board's published June qualification boundaries from 2017 to 2026. No summer exams were sat in 2020 or 2021.
Method
- Each boundary is the published mark divided by the qualification's total marks that June.
