Computer Science / Data Science / AI in Singapore (2026): JC Subject Planning Checklist (NUS/NTU/SMU/SUTD/SIT/SUSS)

Q: What should I take in JC if I’m aiming for CS / data science / AI?
A: Plan backwards from what universities list as prerequisites (and “assumed knowledge”), then choose a subject combination you can actually sustain for two years.

TL;DR If you’re aiming for CS/DS/AI and you’re not 100% sure where you’ll apply, H2 Math is usually the safest default.
The key is not to memorise a single “best combination”, but to verify prerequisites early and build a backup plan you’re comfortable with.

Quick subject map

• TL;DR: H2 Math is the safest default if CS, DS, or AI is still in play.
• Pick your track first: Decide whether you mean software, data, or AI-heavy pathways.
• Prereq verification workflow: Check official pages before locking in JC subjects.

Concrete example: If a student says "I want AI", list six target programmes first, then check which ones require or assume H2 Math before choosing the rest of the combination.
