The conditions the IB publishes. All must be met.
Fill in all six subjects, TOK and EE.
Whether your combination satisfies the published requirement. This is eligibility, not a prediction of admission.
This is the single most consequential thing on this page, and almost nobody writes about it.
NTU states that where Mathematics is a prerequisite, both Analysis and Approaches (MAA) and Applications and Interpretation (MAI) are acceptable, with no preference for one over the other. A student with HL Maths AI meets NTU's Mathematics requirement for Computer Science, Engineering or Data Science exactly as a student with HL Maths AA does.
NUS does not work that way. Its IB prerequisite tables name the course explicitly. Business Administration and Business Analytics asks for a pass in HL MAA. Business Administration and Business AI Systems accepts HL Computer Science, or a good pass in SL MAA, or HL MAI. Landscape Architecture accepts SL Chemistry, SL MAA or SL Physics — or HL MAI. Where NUS wants MAA, MAI does not substitute.
SMU sits at the other end. SMU states Mathematics is not required for most programmes, the exceptions being Economics and Computer Science, where a good pass in IB Mathematics at either Higher or Standard Level is required. Applicants without it may still be considered if they can show an alternative mathematics background. SMU also states it has no language requirement.
The practical consequence: a Singapore student choosing HL Maths AI keeps NTU Engineering open and closes several NUS business programmes. Choosing HL Maths AA keeps both open. That asymmetry is a reason to default to AA when a student can carry it — and a reason not to panic if they cannot.
TOK and the Extended Essay are each graded A to E. They combine — they do not simply add — to award between zero and three points toward the total of 45.
| EE ↓ / TOK → | A | B | C | D | E |
|---|---|---|---|---|---|
| A | 3 | 3 | 2 | 2 | FAIL |
| B | 3 | 2 | 2 | 1 | FAIL |
| C | 2 | 2 | 1 | 0 | FAIL |
| D | 2 | 1 | 0 | 0 | FAIL |
| E | FAIL | FAIL | FAIL | FAIL | FAIL |
Matrix as published by the International Baccalaureate. Worked example from the IB: a candidate with a B in Theory of Knowledge and a C in the Extended Essay is awarded 2 core points. Note that an A in one component and a D in the other still yields 2 — but a D in both yields nothing.
Because none are published, by either university, and we are not willing to invent them.
NUS publishes an Indicative Grade Profile for A-Level and polytechnic applicants only. Its admissions page explains the omission directly: the sample of applicants holding the IB Diploma or NUS High School Diploma is too small to arrive at a grade profile that accurately reflects a programme's academic requirements, so those qualifications are excluded. IB applicants are assessed in the same way as everyone else, on academic and non-academic achievement.
NTU says the same on its own IB admissions page: the sample size of IB Diploma holders is relatively small, so no reflective grade profile is provided. NTU does describe what it looks for — a very good combination of 5s, 6s and 7s across the three Higher Level and three Standard Level subjects, together with good Extended Essay and TOK grades. That is a description, not a threshold.
Every site publishing an "IB cut-off for NUS Medicine" is reporting anecdote. Several say so in their own text, describing their figures as a rough gauge from hearsay drawn from online forums. Those numbers move between sites, are never sourced, and cannot be checked. We would rather give you the two things that are published: what the IB requires for the diploma, and what each university requires by subject.
For a sense of how contested a programme is, the A-Level Indicative Grade Profile remains a reasonable proxy. A course sitting near the top of that table is fiercely competitive whichever qualification you hold.
Every rule in the checker traces to one of these. University prerequisites are revised annually.
NUS prerequisites reflect tables dated December 2025 to February 2026. NTU's minimum subject requirements are marked correct as at October 2025. Confirm against the university's own site before you finalise a subject combination.
It tells you whether a combination is eligible. It cannot weigh your child's strengths against a school's timetable, or against a degree they haven't decided on yet. That conversation is what we do — and we run it two ways.
