How Cambridge Grade Thresholds Work
A grade threshold is the minimum mark required for a particular grade in a particular examination series and option. It is not a permanent target for a subject. Thresholds can change because papers differ in difficulty and because qualifications combine components in specific ways.
Raw marks and grades are different
Your raw mark is the number of marks awarded on a component. A threshold maps a mark—or a combined weighted mark—to a grade. Two papers with the same maximum mark can have different thresholds in different sessions.
Why thresholds change
Examinations are designed to a consistent standard, but no two papers are identical in difficulty. Thresholds help keep the meaning of a grade broadly consistent across series. A more demanding paper may have a lower threshold; an accessible paper may have a higher one.
This does not mean grades are awarded using a fixed percentage such as 80% for an A in every session.
Component and option thresholds
Some tables show thresholds for individual components, while final qualification grades depend on an option or combination of components. Components may also be weighted. Adding raw component marks without checking the syllabus and option can therefore give a misleading predicted grade.
Use the matching table
Match the qualification, syllabus code, session, year and option. Do not use a threshold from another year simply because the subject name is the same. If you practised only one component, treat any component comparison as an indication—not a final qualification grade.
How to use thresholds in revision
Mark the paper accurately first. Then compare with the matching threshold to give the score context. Track raw marks and weak topics as well: moving from 45 to 55 marks is useful progress even if both scores fall in the same approximate grade band.
Aim for a safety margin rather than revising to the exact historical boundary. Thresholds for your future examination are unknown until marking and awarding are complete.
What thresholds cannot tell you
They cannot predict the exact grade boundary for a future series, replace official results or show which topics caused lost marks. Use them as one feedback tool alongside mark schemes, examiner reports and your error log.
