The same subject on other boards, June 2024

Raw marks are not comparable between boards, because the maximum marks differ. The percentage of the maximum is the only fair comparison — and it is usually closer than people expect.

Questions

What was the grade C boundary for OCR A-level Biology in June 2024?
In June 2024, Biology: 112 out of 270; Biology (Advancing Biology): 111 out of 270.
Will the boundaries be the same next year?
No. Boards reset boundaries after every series so a grade means the same thing even when a paper is harder or easier than intended. Past boundaries tell you the likely range, not the answer.
