How to choose JC subject combinations
Your H2 subject combination affects A-Level performance and university course eligibility. Engineering requires H2 Math — NUS lists nothing further in its central prerequisite table, while NTU usually adds one of H2 Physics/Chemistry/Biology/Computing; reading Physics itself requires H2 Physics. Medicine requires H2 Chemistry + (H2 Biology or Physics). Most students take three H2 subjects and one H1 content subject, plus H1 GP and H1 PW. The contrasting-subject requirement (Science students take an Arts subject, Arts students a Math/Science subject, at H1 or H2) preserves university course flexibility — a student set on Medicine should still keep H1 Econs or History to avoid early specialisation lock-in. The 70-point University Admission Score (UAS) replaces the 90-point rank from the 2025 A-Level cohort (AY2026 admissions) — the best 3 H2 subjects plus H1 General Paper make up the 70 points (a fourth content-based subject counts only if it raises the score, which is then rebased to 70), while Project Work is now Pass/Fail only and does not contribute to the score. Subject combination decisions are made before JC1 starts, with limited swap windows in Term 1. The full guide covers per-university (NUS / NTU / SMU / SUTD) prerequisite tables and popular pre-Med, pre-Engineering, and Arts combinations.
