Questions What mark do you need for a grade A in Cambridge Cambridge IGCSE Chemistry 0620? In June 2026, the least mark for the whole subject that reached a grade A was 75 out of 90 in total.
What mark do you need for a grade C in Cambridge Cambridge IGCSE Chemistry 0620? In June 2026, the least mark for the whole subject that reached a grade C was 57 out of 90 in total.
Which series of Cambridge Cambridge IGCSE Chemistry 0620 grade boundaries are there? 14 series, from March 2022 to June 2026: June 2026, March 2026, November 2025, June 2025, March 2025, November 2024, June 2024, March 2024, November 2023, June 2023, March 2023, November 2022, June 2022 and March 2022.
Do Cambridge Cambridge IGCSE Chemistry 0620 grade boundaries change each year? Yes. Across the 4 series here, a grade A in total needed from 63 out of 90 (November 2022) to 78 out of 90 (June 2023).
Other courses Chemistry at other boards Other Cambridge International GCSE courses A series, or the safe rule A paper is graded against the boundaries of the series it was sat in. Choose that series and the grade is the one the board’s boundaries gave that sitting. Where a series published more than one set of boundaries for the whole subject, one for each combination of papers, each grade takes the highest of them, and the line under the grade says so.
The safe rule is for a mark with no series of its own, such as a mock. For each grade it takes the highest boundary in the board’s most recent summer series, up to three of them and leaving out 2020 to 2022, or the course’s main series where it has no summer one. A grade it gives would have been enough in each of them. The line under the grade names the series it counted.
In the app you log a paper in one line, or question by question where asterisk has its questions, and each grade comes from these same boundaries. Open the app .
Not here CCEA, AS level, IB and AP: the app holds no grade boundaries for them, so they are not offered.
Where these numbers come from Boards publish their grade boundaries after each series, and that is all this page holds: each grade’s boundary mark and what the subject or paper is out of, as the board printed them. The papers stay on the boards’ own sites; nothing here reproduces a question or a mark scheme.
These pages hold facts about papers — marks, timings, published grade boundaries — and link to the exam board’s own copy of the paper. No question text or mark scheme is reproduced here.
