The same subject on other boards, June 2025

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 4 boundary for OCR GCSE Chemistry in June 2025?
In June 2025, Chemistry (Gateway Science) — Higher: 73 out of 180; Chemistry (Twenty First Century Science) — Higher: 56 out of 180; Chemistry (Gateway Science) — Foundation: 97 out of 180; Chemistry (Twenty First Century Science) — Foundation: 95 out of 180.
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.
