What is the O Level grading system?
The Singapore-Cambridge GCE O Level examination grading scale is a standardised framework approved by the Ministry of Education, and jointly assessed by the Singapore Examinations and Assessment Board (SEAB) and Cambridge International Education1. In 2026, this scoring system is applicable to 60 O Level syllabuses and is used to evaluate candidates’ performance.
Secondary school students’ grades are divided into two categories, namely passing results (A1 to C6) and failing results (D7 to F9), with different letter grades corresponding to their total marks for each subject. Here is a simple breakdown of O Level grades and marks:
Grade
Marks (%)
A1
75 – 100
A2
70 – 74
B3
65 – 69
B4
60 – 64
C5
55 – 59
C6
50 – 54
D7
45 – 49
E8
40 – 44
F9
0 – 39
While students will not be graded according to a bell curve, their grades will be standards-referenced2. This means that the grade boundaries in the table above may change according to the difficulty level of the paper, ensuring exam standards are comparable year-on-year3.
How to calculate your O Level points? With examples
Students’ O Level grade points are the numerical values attached to each subject’s letter grades, such as the 1 in A1. These grade points can be used in various calculation methods to determine aggregate scores for applications to junior colleges, Millennia Institute, and polytechnic courses.
For junior college (JC) admission: L1R5 + Example
The L1R5 O Level grading system is used for students applying for junior colleges (JC). As of 2026, there are six components to this method of calculation4:
- L1: English or Higher Mother Tongue Language
- R1: One best-scoring Humanities subject
- R2: One best-scoring Math or Science subject
- R3: One best-scoring Humanities, Math, or Science subject
- R4: Any approved best-scoring subject
- R5: Any approved best-scoring subject
Note that subjects in the L category cannot be included in any R components.
Here’s an example of L1R5 calculation:
Subject

L1: English Language

R3: Humanities (Social Studies, Literature in English)

R4: Art

R2: Additional Mathematics

Total Points:

Generally, students would need an L1R5 score of 20 or lower to be admitted into JCs5, with some competitive institutions requiring lower scores.
Depending on the programme, there may be different requirements tailored to the course specifications. For instance, a student applying to join a Science-based JC programme may be required to include more than one Science subject and achieve higher grades in at least one Math subject.
Besides students’ L1R5 score, there are also mandatory subject-specific grade requirements6 that students must achieve to be considered for a coveted spot in JCs. Here is the criteria:
- English Language: A1 to C6
- Mother Tongue Language (any one of the following):
- Chinese, Malay, or Tamil: A1 to D7
- Higher Chinese, Higher Malay, or Higher Tamil: A1 to E8
- Chinese ‘B’ Syllabus, Malay ‘B’ Syllabus, or Tamil ‘B’ Syllabus: Merit or Pass
- Mathematics or Additional Mathematics: A1 to D7
For Millennia Institute (MI) admission: L1R4 + Example
The L1R4 grading system is used for students applying to Millennia Institute (MI). As of 2026, there are five components to this method of calculation7:
- L1: English or Higher Mother Tongue Language
- R1: One best-scoring Humanities, Maths, or Science subject
- R2: One best-scoring Humanities, Maths, or Science subject
- R3: Any approved best-scoring subject
- R4: Any approved best-scoring subject
Here is an example L1R4 aggregate score calculation:
Subject

Generally, the eligibility threshold for MI is an L1R4 score of 20 or lower8. Additionally, students should take note that outside of their L1R4 scores, there are also mandatory subject-specific grade requirements9, as follows:
- English Language: A1 to C6
- Mother Tongue Language (any one of the following):
- Chinese, Malay, or Tamil: A1 to D7
- Higher Chinese, Higher Malay, or Higher Tamil: A1 to E8
- Chinese ‘B’ Syllabus, Malay ‘B’ Syllabus, or Tamil ‘B’ Syllabus: Merit or Pass
- Mathematics or Additional Mathematics: A1 to D7
For polytechnic admission: ELR2B2 + Example
The ELR2B2 scoring system is used for students applying to polytechnic courses. As of 2026, there are five components to this method of calculation10:
- EL: English Language
- R1: One relevant subject
- R2: One relevant subject
- B1: One best-scoring subject
- B2: One best-scoring subject
Here is an example ELR2B2-A score calculation:
Subject

EL: English Language

R1: Business Studies

R2: Higher Tamil

B1: Mathematics

Total Points:

Generally, students need to achieve an ELR2B2 aggregate score of 26 and below, except those applying for a Diploma in Nursing, whose scores must not exceed 2811.
There are four ELR2B2 types in total, each applicable to courses from different disciplines and with minimum entry requirements (MER) varying by course12. Here is a simple breakdown of what each ELR2B2 type is for:
- ELR2B2-A: Humanities, Arts, and Social Sciences
- ELR2B2-B: Mathematics, Science
- ELR2B2-C: Combination of Humanities and Mathematics/Science
- ELR2B2-D: Other specific subjects
Take note that students cannot use the grades of HMTL and MTL of the same language in their aggregate scores. For instance, if a student’s Higher Chinese score is used for the B1, Chinese cannot be used for the B2 score.
How do bonus point deductions work?
Bonus point deductions are points deducted from a student’s gross aggregate score to improve their chances of admission to their desired post-secondary institution. Students can stack up to a total of -4 points13.
Here’s a list of categories that award bonus deduction points:

Post-secondary school cut-off points in Singapore
Post-secondary cut-off points (COPs) refer to the highest O Level score of the last student admitted into the institute or course. Each post-secondary institute has varying cut-off points (COPs), depending on the year and demand for the courses offered.

There are currently no changes to the O Level grading system in 2026.
However, from 2027 onwards, post-secondary O and N Level examinations will be replaced with a standardised Singapore-Cambridge Secondary Education Certificate (SEC), in line with Full Subject-Based Banding (Full SBB) goals16.
Based on the MOE’s announcement in 2024, there are three bands for the SEC exams: G1, G2, and G3, with G3 being the most academically challenging and described as the O Level-equivalent standard17.
Tips & tricks for the O Level examinations
With the O Level examinations commencing on 19 October 2026 onwards18, effective preparation is crucial to performing well and joining your desired courses. Here are a few strategies that can help you get started.
Focus on your chosen relevant subjects
Based on your weakest subjects and key knowledge gaps, create a targeted study plan that encompasses all your chosen subjects. Exchanging notes with peers, finding online subject-based resources, or forming small study groups can also provide additional support and accelerate your learning.
Understand the exam format and syllabus
By staying updated with the latest exam formats and syllabus for each subject, you’ll know what to expect in the exam and can confidently prioritise your efforts without any surprises. This helps you understand marking requirements and manage your revision time slots better, allowing you to make the most of your exam preparation
Practise with past-year papers
One of the most effective ways to prepare for your O Levels is to test your knowledge with past-year papers and review your mistakes. Make sure to time each paper according to the official exam duration, so you can familiarise yourself with the pace required to finish the paper and still have extra time to double-check questions you might be unsure about.
