Frequently asked
- What was the A* boundary for Marine Science in November 2022?
- For Papers 11, 21, 31, 41, an A* needed 221 out of 300 weighted marks (74%). Other paper combinations have their own thresholds — see the table above.
- What mark was a pass (grade E) in Marine Science November 2022?
- Grade E is the lowest pass. For Papers 11, 21, 31, 41 it needed 82/300 (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.
- Did Marine Science grade boundaries go up or down in November 2022?
- Compared with June 2022, the A* boundary for Papers 11, 21, 31, 41 rose by 1 mark (220 → 221) and the E boundary rose by 1 mark (81 → 82). Boundaries move to keep the standard constant when a paper turns out harder or easier than usual.
