- It does not affect the grade you receive but gives you more information about it.
- It will appear on your statement of results but not on your certificate.

A Closer Look into the Marking and IGCSE Grade Boundaries
Understanding how Cambridge ensures fair and accurate marking of over 8 million scripts annually
Automated Marking
For papers that are Multiple Choice, they are marked automatically by a computer, ensuring accuracy and consistency.
Expert Human Marking
For any other exam, every student's work is marked in the same way. Cambridge ensures that examiners are teachers or experts in the subject, and also carefully selected and trained.
Statistical Analysis
After marking, the board sets grades using a mixture of statistical evidence and expert judgment to agree on grade boundaries for the year of examination.
Fair Grading Guarantee
This process ensures that exam papers may vary in difficulty from year to year, but grade boundaries are set in the right place so candidates are not given a lower grade because the paper they sat for is more difficult than last year's.
