Every boundary used by the calculator comes from an official AQA or OCR subject-level grade-boundary file.

The first release contains June 2019 and June 2022–2025. Summer 2020 and 2021 had no standard UK summer examination series. June 2022 is retained as a selectable comparison and identified as a transitional grading year.
