IB Subject Planning for Singapore Universities (2026): What to Verify (HL/SL Choices, Assumed Knowledge, MTL)
Q: I’m an IB Diploma student in Singapore. How do I pick subjects without accidentally closing university options?
A: Treat it as a verification problem. Pick a “default plan” that matches your likely degree family, then check the official admissions pages (and any subject prerequisite PDFs) for the specific universities/programmes you’d realistically apply to.
TL;DR
IB requirements aren’t “one rule”. Eligibility, subject prerequisites, and assumed knowledge can differ by university and programme.
Your fastest, safest move is to pick a default plan (STEM-flexible vs humanities vs health) and then verify the exact rules on the official pages linked below.

1 | Before you start: “eligibility” vs “programme prerequisites” vs “assumed knowledge”
When students say “requirements”, they often mean three different things:
- Eligibility: Whether your IB credential/results are accepted for admissions in the first place (and under what conditions).

For NUS, the clearest way to verify is their IB subject prerequisite PDF (May 2021 and beyond):
