How the Weighting Factor Calculation Works
For high-stakes subjects like Biology (0610) or Physics (0625), the "Raw Mark" you see on a paper is rarely your final score. Cambridge applies a multiplier to ensure that a 40-mark MCQ paper and an 80-mark Theory paper contribute their intended percentages (usually 30% and 50% respectively).
| Component Type | Typical Raw Max | Weighting Factor | Weighted Contribution |
|---|---|---|---|
| Paper 2 (MCQ) | 40 Marks | 1.5 | 60 Marks (30%) |
| Paper 4 (Theory) | 80 Marks | 1.25 | 100 Marks (50%) |
| Paper 6 (Alt to Practical) | 40 Marks | 1.0 | 40 Marks (20%) |
| Total Syllabus Max | 200 Marks (100%) | ||
Why Thresholds Matter for 2026 Students
A "Grade Threshold" is the minimum weighted mark required to achieve a specific grade. These are released by exam boards after the marking process. By using the November 2025 data, this tool provides a benchmark. For instance, if the A* threshold for 0580 Mathematics Variant 22 was 172/200, scoring above that in your mocks is a strong indicator of success.
Frequently Asked Questions
How do I find my component marks? +
Component scores are listed in your "Candidate Results Service" or your "Component Marks Report" provided by your school's exams officer. If you are practicing past papers, calculate your score using the official mark scheme, then enter those numbers here to see the weighted result.
Is the 9-1 grading system supported? +
Yes. This calculator detects whether the syllabus uses the A*-G scale or the 9-1 scale (UK-aligned) and adjusts the threshold comparison table automatically to reflect the correct boundaries.
What is a 'Variant'? +
Variants (11, 12, 13 etc.) correspond to different administrative zones/time zones. Thresholds differ between variants to ensure that a harder paper in one time zone does not disadvantage students compared to an easier paper elsewhere.
