SEC Transition Watch: What O-Level Physics Candidates Need to Know

In one line

MOE’s Full SBB infographic (updated Sep 2025) says mixed-form classes from 2024 will sit the Singapore-Cambridge Secondary Education Certificate (SEC) at the end of Sec 4, making 2026 the final O-/N-Level cohort and 2027 the first SEC sitting (FSBB infographic; see also MOE’s 2024 press release on SEC).

Key points

  • SEAB has published 2027 SEC syllabus pages (G1/G2/G3); for Physics, this includes a G3 syllabus PDF (SEAB SEC syllabus index; Physics (G3) PDF).
  • If your cohort is still taking O-Level Physics (6091), keep training for today’s Paper 3 expectations while monitoring SEAB updates for any SEC-related refinements (SEAB 6091 syllabus PDF; SEAB SEC page).

10 secondsCheck MOE timeline, SEAB SEC pages, G3 Physics syllabus, current 6091 Paper 3, school briefings, and practical-skill continuity.
100 secondsKeep training today’s O-Level skills while saving SEC updates, because measurement, data, and evaluation habits are likely to remain useful.
Concrete exampleA Sec 4 student sitting 6091 in 2026 should still practise Paper 3 apparatus routines, not wait for SEC wording.
