What is GCE O-Level?
The Singapore-Cambridge GCE O-Level examination is taken by students in their final year of secondary school, mostly at age 16 or 17. It is held annually in Singapore during the month of October. The examinations are mainly set by the University of Cambridge Local Examinations Syndicate (UCLES), while Mother Tongue subjects such as Chinese are set by the Singapore Ministry of Education (MOE).
This system is equivalent to the GCSE examination taken by students in the United Kingdom and has a global recognition similar to that of Cambridge IGCSE.
GCE O-Level Grading
Candidates are graded based on their performance relative to the cohort. Grades in exam subjects consist of a number with an accompanying letter as shown in the table below:
The grades of 5 or 6 subjects (depending on the scoring system used) taken are added to give an aggregate score known as L1R5 (1 language subject and 5 relevant subjects) or L1R4. This score is calculated by adding up the numerical of each grade. For example, a candidate who scores a grade of A1 in 6 subjects will have an L1R5 score of 6.
