Common questions
What were the Chemistry A (Gateway Science) grade boundaries in June 2026?
In June 2026, a grade 4 needed 100 out of 180 on the Foundation tier. On the Higher tier, a grade 7 needed 139 out of 180 and a grade 4 needed 76. The full table, with the boundaries for each paper, is at the top of this page.
Where do these OCR GCSE Chemistry A (Gateway Science) grade boundaries come from?
Every number is copied from OCR's own published grade boundary document for that series, which is linked under each table. We lay them out by course so you don't have to search a document covering every subject, and nothing is changed or estimated.
Why do grade boundaries change every year?
Boundaries are set after each exam has been marked, so that a grade means the same standard even when one year's paper is harder than another's. A harder paper usually has lower boundaries. That is why an old paper is best marked against its own year's boundaries, which is what the tables here are for.
When are new Chemistry A (Gateway Science) grade boundaries published?
OCR publishes grade boundaries on results day: for summer exams that is mid August for A levels and a week later for GCSEs, and November and January series get theirs on their own results days. We add them here after that, usually well before the papers themselves are released.
More grade boundaries: every OCR course or every board.
