If your child is in Secondary 3 this year, they will not sit the GCE O-Level. From 2027 the GCE N(T)-, N(A)- and O-Level examinations are combined and renamed the Singapore-Cambridge Secondary Education Certificate (SEC). The first cohort under Full Subject-Based Banding — students who started Secondary 1 in 2024 — sits it at the end of Secondary 4 in 2027. Students in Secondary 4 this year still sit the O-Level in 2026.
This guide sets out what changes, what stays the same, and what it means for JC admission. Every fact below comes from the Ministry of Education (MOE) and the Singapore Examinations and Assessment Board (SEAB); the sources are listed at the end.
Subjects are taken at G1, G2 or G3
Under Full Subject-Based Banding, each subject is taken at one of three levels: G1, G2 or G3 (“G” stands for General). A student can take different subjects at different levels. SEAB states that the three levels have the same examination format and standards as the old papers:
- G3 — the O-Level standard
- G2 — the N(A)-Level standard
- G1 — the N(T)-Level standard
For a student taking English or Mathematics at G3, the paper they sit in 2027 follows the O-Level format and standard. The preparation does not change.
When the examinations happen
- September: written papers for English Language and the Mother Tongue Languages.
- October to November: written papers for all other subjects.
- January of the following year: results. The first SEC results are released in January 2028.
All subjects and all levels are examined in the same year-end period.
JC admission: L1R4 ≤ 16 from the 2028 JAE
This is the change that matters most for families aiming for junior college. From the 2028 Joint Admissions Exercise — the one the first SEC cohort enters — MOE replaces the L1R5 ≤ 20 requirement with L1R4 ≤ 16. Five subjects count instead of six.
The L1R4 aggregate is made up of:
- L1: G3 English, or Higher Mother Tongue Language
- R1: the best G3 Humanities subject
- R2: the best G3 Mathematics or Science subject
- R3: the best remaining G3 Humanities, Mathematics or Science subject
- R4: the best remaining G3 subject
Four further rules apply:
- Only G3 subjects count towards the aggregate for JC and Millennia Institute admission. A subject taken at G2 cannot be used.
- Minimum grades: G3 English at A1–C6, and G3 Mathematics or G3 Additional Mathematics at A1–D7, plus the Mother Tongue requirement.
- Bonus points are capped at 3, down from 4. Students selected for a Language Elective Programme at a JC receive 2 more.
- Millennia Institute admission requires L1R4 ≤ 20.
Students in Secondary 4 this year apply in the 2027 JAE under the existing L1R5 ≤ 20 rule. Our L1R5 calculator and cut-off points guide apply to them.
Polytechnic admission
SEAB lists ELR2B2 as the aggregate for polytechnic admission. MOE’s polytechnic admission pages set out the full criteria for the SEC cohort.
What this means for your child
- English carries more weight. With five subjects in the aggregate instead of six, each subject is a fifth of the score rather than a sixth. Every JC applicant needs G3 English at C6 or better, and for most students English is the L1 subject in the aggregate.
- Check the level of every subject. Only G3 subjects count for JC. If your child hopes to apply, confirm with the school which subjects are at G3 before Secondary 4 begins.
- One subject fewer counts. MOE made the change so that students can carry one subject fewer and use the time for other interests.
- The papers themselves do not change. G3 English and G3 Mathematics follow the O-Level format, so a method built for those papers still applies.
How A-Worthy prepares SEC students
Our O-Level English and O-Level Mathematics programmes teach to the G3 standard, which is the O-Level standard. A student in Secondary 3 today is taught the same named frameworks for each question type as our O-Level students, on the same paper format.
