What examination will a PG2 student eventually sit, and how are G2 results graded? From 2027, the Singapore-Cambridge Secondary Education Certificate (SEC) replaces the separate GCE N(T), N(A) and O-Level examinations. Candidates sit subjects at their respective G1, G2 or G3 subject levels, and their single SEC certificate reflects the subjects and levels taken. A PG2 pupil will generally take most subjects at G2 initially, but the final certificate depends on the student’s actual subject-level combination at the time of examination.
The date distinction is important. SEAB’s published 2027 G2 syllabuses and examination arrangements apply to the 2027 graduating cohort. A pupil entering Secondary 1 in 2027 is a later cohort and will sit the SEC several years afterwards. The rules below explain the new system as published for 2027, but parents must check the syllabus and timetable for their child’s actual examination year.
This guide explains the G2 grade scale, what SEAB considers a certificate-level pass, how grade mapping is used for certain aggregate calculations, when the 2027 cohort sits written examinations and what the results certificate records. It also explains why a G2 grade should not be casually compared with a G3 grade or treated as the student’s permanent academic identity.
What is the SEC?
SEAB explains that from 2027 the GCE N(T), N(A) and O-Level examinations are combined and renamed the Singapore-Cambridge Secondary Education Certificate. The examination continues to be jointly examined and awarded by SEAB, MOE and Cambridge International Education. The certificate records the subjects and subject levels the candidate sat.
There is no change in the overall examination standards simply because the qualification has a new name. Candidates take the syllabuses at G1, G2 or G3. The subject level is part of the qualification information, so a grade should always be read together with the subject and level.
How G2 subjects are graded
For G2 subjects, SEAB publishes grades from 1 to 6. The G1 scale uses A to E, while G3 uses A1 to 9. These are different grading structures aligned to the respective subject levels. A smaller number is a stronger grade in the G2 scale, but a grade should not be interpreted without knowing the subject and level.
| Subject level | Published grade scale | Certificate award threshold |
|---|---|---|
| G1 | A, B, C, D, E | Grade D or better |
| G2 | 1, 2, 3, 4, 5, 6 | Grade 5 or better |
| G3 | A1, A2, B3, B4, C5, C6, D7, E8, 9 | Grade E8 or better |
SEAB states that a certificate is awarded if a candidate obtains grade E8 or better for a G3 subject, grade 5 or better for a G2 subject, or grade D or better for a G1 subject. This is a subject-level certificate threshold; it does not automatically mean that the candidate meets every prerequisite for a particular post-secondary course.
Do not compare grade numbers across G1, G2 and G3 casually
A G2 grade 2 and a G3 grade 2 do not mean the same thing because G3 does not use the same grade sequence. G3 uses A1 to 9, G2 uses 1 to 6 and G1 uses A to E. When a result is discussed, state the subject, the level and the grade together.
A student may have different levels in different subjects. The SEC certificate reflects that combination rather than forcing every subject into one common stream. This is one of the important changes under Full SBB: the certificate shows what the student actually studied and sat for.
When grade mapping is used
SEAB publishes grade mapping for circumstances where grades from subjects taken at more demanding levels need to be converted for an aggregate score used in post-secondary progression. The mapping is not a statement that every G3 subject is automatically interchangeable with a G2 subject for every purpose. It is used where a particular admission aggregate requires it.
| G3 grade | Mapped G2 grade |
|---|---|
| A1 to B3 | 1 |
| B4 to C6 | 2 |
| D7 | 3 |
| E8 | 4 |
| 9 | 5 |
| G2 grade | Mapped G1 grade |
|---|---|
| 1 to 3 | A |
| 4 | B |
| 5 | C |
| 6 | D |
For example, SEAB illustrates that a G3 English Language grade may be mapped to the relevant G2 scale when computing an aggregate such as ELMAB3. A G1 subject may not be used for that particular aggregate. Different admissions exercises can use different subject requirements and formulas, so families should read the current admission rules rather than calculate an offer from a grade-mapping table alone.
The 2027 SEC examination timeline
SEAB’s published SEC information sets out a common examination structure from 2027. The written examinations for English Language and Mother Tongue Languages are held in September. Written examinations for the other subjects are held from October to November. Non-written components such as Science practical, oral and listening comprehension are scheduled before the written examinations, as in current practice.
Results are released in January of the following year. This creates a common results-release period for the SEC. Exact subject dates and reporting arrangements are issued in the examination timetable for the relevant year. Students should follow the official school instructions for examination venues, reporting times, materials and conduct.
| Component | Published 2027 SEC timing |
|---|---|
| English Language written examination | September |
| Mother Tongue written examination | September |
| Other written examinations | October to November |
| Science practical, oral and listening components | Before written examinations, according to subject timetable |
| Results release | January of the following year |
These dates describe the 2027 graduating examination cohort, not the future timetable for a student starting Secondary 1 in 2027. The incoming cohort will have a later examination year and must use the future SEAB timetable when it is published.
One certificate records subjects at different levels
SEAB explains that candidates receive a single SEC certificate reflecting the subjects taken and their respective G1, G2 or G3 levels. This is important for a student who takes, for example, English at G3, Mathematics at G2, Science at G2 and another subject at G1. The certificate reports the actual subject-level combination, rather than describing the pupil by one old stream label.
The school candidate is registered through the school. Students and parents should check the subject entries, levels and personal details shown in the official registration information. If something appears incorrect, raise it through the school’s examination administration process promptly.
What the SEC certificate does not guarantee
A grade that meets the certificate threshold does not automatically guarantee a place in a junior college, Millennia Institute, polytechnic, ITE programme or a particular course. Each pathway has its own subject prerequisites, aggregate calculation, eligibility conditions and application process. Some courses require a specified subject grade or level.
Families should therefore separate three questions: has the student obtained the SEC certificate for the subjects taken; does the student’s subject combination meet the required aggregate or course prerequisites; and does the student satisfy the current admissions criteria? A positive answer to one does not automatically answer the others.
What a PG2 student entering Secondary 1 in 2027 should focus on now
A new Secondary 1 pupil does not need to revise the entire 2027 SEC timetable or start preparing for a final examination several years away. The immediate priorities are to understand the school’s subject allocation, build secure foundations, learn how assessment feedback works and ask for help when a concept is unclear.
The student’s final subject levels may change at appropriate junctures under Full SBB, subject to eligibility, school assessment and available offerings. The family should focus on consistent learning and informed conversations with teachers, not pressure the child to optimise a hypothetical grade combination years in advance.
Questions parents should ask when examination registration begins
- Which subjects is the student registered for, and at what G level?
- Are the subject codes and syllabus versions correct for this examination year?
- Which components are written, oral, listening or practical?
- What are the exact reporting times and examination materials?
- How does the school communicate timetable changes?
- Which current post-secondary prerequisites apply to the student’s intended pathway?
- How are results and the SEC certificate delivered after release?
Frequently asked questions
Is G2 grade 5 a certificate-level pass?
SEAB states that a G2 subject grade of 5 or better meets the subject-level threshold for the SEC certificate.
Is G2 grade 6 a certificate pass?
No. The published G2 certificate threshold is grade 5 or better.
Does the SEC replace the GCE N- and O-Level examinations in 2027?
Yes. From 2027, the GCE N(T), N(A) and O-Level examinations are combined and renamed the SEC.
Will a PG2 pupil necessarily take all subjects at G2 in the final year?
No. Students may take different subjects at different G levels under Full SBB. The certificate records the actual subject levels taken.
Do grade mapping tables convert every subject for every admissions purpose?
No. SEAB states that mapping is used when required to compute particular aggregate scores for progression. Always follow the current admission criteria.
Does the 2027 examination timetable apply to a pupil entering Secondary 1 in 2027?
No. The 2027 timetable applies to the 2027 graduating cohort. A new Secondary 1 pupil in 2027 will sit a later cohort’s examination and should use that year’s published timetable.
