Paper (component) thresholds — March 2022
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.
| Paper | Max | A | B | C | D | E |
|---|---|---|---|---|---|---|
| Paper 12 | 40 | 2460% | 2050% | 1743% | 1435% | 1230% |
| Paper 22 | 60 | 3559% | 3050% | 2339% | 1830% | 1119% |

Frequently asked
- What was the A* boundary for Biology in March 2022?
- For Papers 12, 22, 33, 42, an A* needed 187 out of 260 weighted marks (72%). Other paper combinations have their own thresholds — see the table above.
- What mark was a pass (grade E) in Biology March 2022?
- Grade E is the lowest pass. For Papers 12, 22, 33, 42 it needed 72/260 (28%). 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.
