Paper (component) thresholds — March 2025

The minimum raw mark on each individual paper. Cambridge weights and adds these to set the syllabus boundaries above; there is no A* at paper level.

March 2025 vs March 2024

Change in the minimum mark for matching paper routes (same series, one year earlier). Positive = harder to reach the grade.

Frequently asked

What was the A* boundary for Mathematics in March 2025?
For Papers 12, 32, 42, 52, an A* needed 231 out of 250 weighted marks (93%). Other paper combinations have their own thresholds — see the table above.
What mark was a pass (grade E) in Mathematics March 2025?
Grade E is the lowest pass. For Papers 12, 32, 42, 52 it needed 94/250 (38%). Below that the result is U (ungraded).
Why are the paper thresholds different from the overall boundaries?
Cambridge sets a threshold for each paper (component) first, then weights and adds them to get the syllabus boundary for each combination of papers. Your grade comes from the weighted total, not from any single paper. Paper thresholds have no A* — the A* only exists at syllabus level.
Did Mathematics grade boundaries go up or down in March 2025?
Compared with March 2024, the A* boundary for Papers 12, 32, 42, 52 rose by 5 marks (226 → 231) and the E boundary rose by 2 marks (92 → 94). Boundaries move to keep the standard constant when a paper turns out harder or easier than usual.
