Frequently asked
- What is a typical A* boundary in Chemistry?
- Across 6 sessions from June 2022 to June 2026, the A* boundary for Papers 1, 2, 3, 4 and 5 has ranged from 68% (June 2022) to 80% (November 2024), averaging 77%. The E boundary has ranged from 20% to 32%. In June 2026 it was 80% for A* and 31% for E.
- How is the Chemistry grade calculated?
- Cambridge converts each paper's raw mark to a weighted mark, adds them, and compares the total with the syllabus thresholds for your combination of papers. For Papers 11, 21, 31, 41, 51 in June 2026 the maximum was 260; the calculator above does this arithmetic for you.
- Why do Chemistry grade boundaries change every session?
- Boundaries are set after marking so that a grade represents the same standard whether the paper was slightly harder or easier. A harder paper gets lower boundaries. March, June and November series are set independently, which is why the same grade can need different marks in the same year.
