Where do these AQA GCSE Combined Science: Trilogy grade boundaries come from?
Every number is copied from AQA'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 Combined Science: Trilogy grade boundaries published?
AQA 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 AQA course or every board.
