Raw marks for the whole subject. The small figure under each is that mark as a percentage of the maximum — the only number that compares fairly across boards.

The same subject on other boards, June 2026

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 Edexcel A-level Chemistry in June 2026?
In June 2026, Chemistry: 140 out of 300.
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.
