- Cambridge sets a threshold for each component and for each option (a combination of components). Only the option thresholds decide the grade, on the weighted total shown as the maximum.
- AS Level rows have no A* grade, and no component has an A* threshold.
- Staged assessment means the AS Level components were taken in an earlier series.

Common questions
What were the Computer Science grade boundaries in June 2026?
In June 2026, an A needed 206 out of 300 and an E needed 83 on A Level linear (components 11, 21, 31, 41). On A Level linear (components 12, 22, 32, 42), an A needed 206 out of 300 and an E needed 83. On A Level linear (components 13, 23, 33, 43), an A needed 216 out of 300 and an E needed 96. The full table, with the boundaries for each paper, is at the top of this page.
Where do these Cambridge A level Computer Science grade boundaries come from?
Every number is copied from Cambridge International'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 Computer Science grade boundaries published?
Cambridge publishes grade threshold tables when results are released: in August for the June series, in January for November and in May for March. We add them here after that.
More grade boundaries: every Cambridge course or every board.
