Understanding IGCSE Grading
The IGCSE uses the percentage uniform mark (PUM) to map raw marks to grades A* (highest) to G (lowest). Boundaries shift by subject and session.
A*
90%+
Outstanding Achievement
A
80-89%
Excellent Performance
B
70-79%
Good Achievement
C
60-69%
Satisfactory Pass
Important Note: Boundaries vary by subject and year. Maths can have slightly lower boundaries; English sometimes higher.
What Does 70% Mean in IGCSE?
- Usually Grade B.
- Sometimes close to the A boundary depending on the session.
