Q: What does Backward Planning JC Subjects for University Courses cover? A: Organised by target degree, this guide tells you the required H2 subjects, recommended H2 subjects, indicative UAS range, and which JCs offer the combination you need - so you can plan from the outcome backward to your JC subject choice.
TL;DR Start with the degree you want. Look up its required subjects and work backward to your JC combination. Do not trust rumour or old guides - always verify requirements on each university's official admissions pages before you commit. Under the 2026 UAS (70RP), only your best 3 H2 + 1 H1 count toward your score, so your choice of core H2 subjects is more important than ever. Use this guide as a planning map, then use https://eclatinstitute.sg/igp-comparison for indicative grade benchmarks.

Concrete example: how backward planning works
If Medicine is one possible target, do not choose JC subjects by what feels easiest in Sec 4. Work backward: confirm H2 Biology, H2 Chemistry, and H2 Mathematics requirements first, then check whether the JC combination keeps your backup courses open.
Status: Last reviewed 2026-03-28. Subject prerequisites and UAS benchmarks can change across intake years. Always verify from official sources before making final decisions.
1 | Why backward planning matters under the 2026 UAS
Starting from the 2026 university admissions cycle, the A-Level scoring system shifts to a maximum of 70 rank points (from 90). Only your best 3 H2 + 1 H1 contribute to your base UAS. This changes the calculus for backward planning:
You have fewer H2 "slots" than under the old system. If you need H2 Biology for Medicine and H2 Physics for engineering as a backup, you need both in your 3 H2 slots - which means your third H2 choice is load-bearing.
The "4th H2 for safety" strategy is weaker - a fourth H2 adds workload without directly improving your UAS unless it outperforms one of your top three.
Starting from the destination makes it easier to allocate your 3 H2 slots correctly.
NUS Yong Loo Lin School of Medicine / NTU Lee Kong Chian School of Medicine
Required H2 subjects:
H2 Biology
H2 Chemistry
H2 Mathematics (or H2 Further Mathematics)
These three subjects are effectively your minimum Science stream. Most successful applicants also hold H2 Physics, giving a PCMB or BCMP profile.
Recommended H2 subjects:
H2 Physics (rounds out scientific literacy and is expected by many tutors/admissions guidance)
H2 Further Mathematics (for candidates aiming at scholarship-level profiles)
Indicative UAS range: Typically the highest-demand programmes. Expect to need a very strong UAS - check https://eclatinstitute.sg/igp-comparison for the current indicative grade profiles. Both programmes also have additional selection components (UMAT/BMAT-equivalent aptitude tests, multiple mini-interviews).
Subject combination to aim for: H2 Biology, H2 Chemistry, H2 Mathematics, plus either H2 Physics or another H2 of your choice.
JC availability: All mainstream JCs offer H2 Biology, H2 Chemistry, and H2 Mathematics. If you want H2 Physics as your fourth, confirm your JC offers BCMP combinations (some JCs have cap rules on 4 H2 combinations).
Planning flag: There is no established bridging module for H2 Biology at NUS Medicine or NTU LKCMedicine. If you do not have H2 Biology at admission, you are typically ineligible. Do not leave this subject out and assume bridging will fix it.
Subject combination to aim for: H2 Biology, H2 Chemistry, H2 Mathematics is the safe core. The fourth H2 or H1 subject is flexible.
4 | Engineering
NUS Faculty of Engineering / NTU College of Engineering / SUTD / SIT Engineering
Required H2 subjects:
H2 Mathematics (hard requirement at NUS, NTU, SUTD, SIT)
H2 Physics or H2 Chemistry (the exact science requirement varies by discipline - see below)
By discipline:

Recommended H2 subjects: H2 Physics is the most universally useful science for engineering, followed by H2 Chemistry. For most disciplines, a PCME or PCM combination satisfies the requirement.
Indicative UAS: Varies significantly by programme. Computer Engineering and Electrical Engineering at NUS/NTU have higher historical cut-offs than some other engineering disciplines. Use https://eclatinstitute.sg/igp-comparison for current data.
Subject combination to aim for (safe core): H2 Mathematics + H2 Physics + H2 Chemistry. Add a fourth subject (Economics or Humanities) based on your school's contrasting-subject rule.
JC availability: PCME and PCM are offered at all JCs. If you want to keep Chemical Engineering in play, confirm your JC offers H2 Chemistry. If you want Biomedical Engineering, holding both H2 Chemistry and H2 Biology strengthens your profile - but this may require a four-science configuration, which is JC-specific.
5 | Computing, Data Science, and Artificial Intelligence
NUS School of Computing / NTU SCSE / SMU School of Computing and Information Systems / SUTD Information Systems and Technology / SIT Computing
Required H2 subjects:
H2 Mathematics (universally required across NUS SoC, NTU SCSE, SMU SCIS, SUTD, SIT)
H2 Physics or H2 Chemistry: not universally required for CS/IS, but NTU SCSE and some NUS tracks note it as preferred
H2 Computing (the JC subject): Not a prerequisite at any major computing faculty - eligibility is based on H2 Mathematics, not whether you studied Computing in JC.
H2 Further Mathematics (signals strong mathematical aptitude for competitive programmes)
H2 Economics (useful context for Information Systems and Business Analytics tracks)
Indicative UAS: Computer Science at NUS and NTU is among the more competitive programmes. AI and Data Science tracks are similarly high-demand. Check https://eclatinstitute.sg/igp-comparison.
Subject combination to aim for: H2 Mathematics is your critical subject. A PCM or PCME combination satisfies all computing and data science prerequisites. A HELM combination (History/Econ/Lit + Math) also satisfies most CS prerequisites - H2 Mathematics is the load-bearing requirement.
JC availability: H2 Mathematics is offered at all JCs. H2 Computing is not offered everywhere - check your specific JC, but note it is not a prerequisite.
6 | Business, Accountancy, and Economics
NUS NUS Business School / NTU Nanyang Business School / SMU Lee Kong Chian School of Business and School of Accountancy / SIT Business
Required H2 subjects:
Generally none that are hard prerequisites - most business and accountancy programmes in Singapore do not state a mandatory H2 subject.
A passes in H2 subjects (grade threshold) plus the overall UAS/rank point is the primary gate.
Recommended H2 subjects:
H2 Mathematics (strongly recommended across all institutions, and required for double-degree programmes combining Business with Computing or Engineering)
H2 Economics (useful background, but not a hard prerequisite at most institutions)
Indicative UAS: Business programmes across NUS, NTU, SMU are moderately to highly competitive. Accountancy at NUS and SMU is competitive. Check https://eclatinstitute.sg/igp-comparison.
Subject combinations that work:
PCME, BCME, HELM, HEM - all satisfy business admissions requirements
Arts combinations without H2 Math are generally still eligible for business programmes but may face quantitative adjustment in Year 1 modules
Planning flag: If you are considering a Business + Computing double degree at NUS (BBA/Computing), H2 Mathematics is required. Plan accordingly if this is your target.
JC availability: No niche subject is required. Any JC combination that gets you to the required UAS threshold is sufficient.
7 | Law
NUS Faculty of Law / SMU School of Law
Required H2 subjects:
No specific H2 subjects are stated as hard prerequisites at NUS or SMU Law.
Admissions is primarily grade-based (UAS) plus a written aptitude test.
Recommended H2 subjects:
General Paper performance is often cited as an indicator of the writing, reasoning, and analytical skills law schools look for
H2 Literature, H2 History, H2 Economics are commonly associated with strong law applicants, but are not prerequisites
H2 Mathematics is not required - but it does not disadvantage you
Indicative UAS: Law is among the most competitive programmes at NUS and SMU. Verify current indicative profiles at https://eclatinstitute.sg/igp-comparison. NUS Law and SMU Law also use the Law Admission Test (LAT) as a selection component - this is entirely independent of your subject combination.
Subject combination to aim for: Any combination that lets you achieve a competitive UAS and perform strongly in GP. HELM, HEM, or even a Science-stream combination (PCME) with strong GP performance can work.
JC availability: No specific subjects required - any JC is viable.
8 | Architecture
NUS Department of Architecture / NTU School of Art, Design and Media (Architecture track)
Required H2 subjects:
H2 Mathematics (NUS Architecture requires or strongly recommends H2 Math)
No hard science prerequisite for most architecture programmes - but a portfolio and/or design aptitude assessment is a separate component
Recommended H2 subjects:
H2 Art (demonstrates design interest; relevant to portfolio-based selection)
H2 Physics (useful assumed knowledge for structures and environmental systems modules in Year 1)
Subject combination to aim for: H2 Mathematics is the priority. A PCM or PCME combination satisfies requirements and leaves Physics for assumed-knowledge preparation.
JC availability: H2 Art is offered at some but not all JCs. It is recommended but not universally required for architecture admissions. Confirm at your JC.
9 | Medicine-adjacent: Biomedical Sciences, Life Sciences, Food Science
NUS / NTU Life Sciences, Biomedical Sciences, Food Science
Required H2 subjects:
H2 Biology or H2 Chemistry (most programmes require at least one)
H2 Mathematics (required or strongly recommended)
Both H2 Biology and H2 Chemistry together provide the strongest preparation
Recommended H2 subjects:
H2 Physics (useful for biophysics and pharmaceutical sciences tracks)
Indicative UAS: Variable by programme. Biomedical Sciences is competitive; some Life Science tracks have broader intake ranges. Check https://eclatinstitute.sg/igp-comparison.
Subject combination to aim for: BCME or BCM (Biology, Chemistry, Mathematics + one other). This is also the "safe" fallback if Medicine/Pharmacy does not work out, since the same combination keeps these life science tracks open.
10 | Social Sciences, Psychology, and Humanities
NUS / NTU / SMU / SUSS social science and humanities programmes
Required H2 subjects:
Generally no hard H2 subject prerequisites for social science, psychology, communications, or humanities programmes.
SMU's Economics programme does not mandate H2 Economics (though it is commonly taken by applicants).
Recommended H2 subjects:
H2 Mathematics: useful for economics, psychology research methods, and sociological statistics
H2 relevant to the field (e.g., H2 History for History degrees, H2 Economics for Economics degrees)
Subject combinations that work: Arts-stream combinations (HELM, HEM, HEL) are the natural fit. Science-stream students are equally eligible.
11 | Nursing and Allied Health
NUS Alice Lee Centre for Nursing Studies / NTU / SIT Nursing and Allied Health programmes
Required H2 subjects:
H2 Biology and/or H2 Chemistry (check by programme - NUS Nursing typically requires at least H2 Chemistry or H2 Biology at the required grade)
H2 Mathematics may be required or recommended depending on the programme
Indicative UAS: Nursing programmes are moderately competitive; some Allied Health tracks (Physiotherapy, Occupational Therapy) are more selective. Check https://eclatinstitute.sg/igp-comparison.
Subject combination to aim for: At minimum, include H2 Chemistry or H2 Biology. BCME provides maximum flexibility across clinical and life science programmes.
12 | PCME vs BCME for medicine - both work, here is why
This is the most frequently recurring question in JC subject planning forums and in our own enquiries: "I want to do medicine - should I take PCME or BCME?"
The short answer is that both satisfy the H2 science count requirement for NUS/NTU Medicine - and neither is clearly superior. The decision comes down to your strengths and your backup options.
The prerequisite logic
NUS and NTU Medicine require at minimum:
H2 Biology
H2 Chemistry
H2 Mathematics
Both PCME and BCME include H2 Chemistry and H2 Mathematics. The difference is the third content H2:
Combination
Third science H2
Satisfies medicine?
Sacrifices
BCME
H2 Biology
Yes - Bio + Chem = 2 H2 sciences
H2 Physics
PCME
H2 Physics
No - Physics + Chem = 2 H2 sciences, but no H2 Biology
H2 Biology
Wait - PCME does not satisfy the medicine prerequisite? Correct: PCME without H2 Biology is ineligible for NUS/NTU Medicine because H2 Biology is a stated requirement, not merely a recommended subject. H2 Physics is not a substitute.
If you want to take PCME and keep medicine open, you must take H2 Biology as a fourth subject (PCMB or PCMBE). This is a heavy combination - four content H2 subjects - and not all JCs permit it without restrictions.
Why BCME is the cleaner medicine route
BCME (Biology, Chemistry, Mathematics, Economics) satisfies all medicine prerequisites in a standard 3 H2 + 1 H1 load. It sacrifices Physics, which means:
Some physics-heavy engineering disciplines become ineligible (see the engineering table in section 4)
NTU Engineering bridging for missing Physics may be an option as a fallback - but it requires deliberate planning
For a student whose primary goal is medicine with a secondary interest in life sciences (Pharmacy, Biomedical Sciences, Nursing), BCME is the standard recommended combination.
Why some students choose PCME + H2 Bio (PCMB)
Students who want genuine optionality across medicine and engineering take all four science H2 subjects. Under the 2026 UAS (70RP), only your best 3 H2 count - so the fourth H2 contributes workload without directly improving your score unless it outperforms one of your other three. This is a legitimate strategy for students who are genuinely undecided and academically strong enough to carry the load.
For the Duke-NUS Graduate Medical School (postgraduate MD) route, A-Level science prerequisites are not evaluated at application - your undergraduate degree is. This is relevant for students who find themselves post-results without a medicine-eligible combination: Duke-NUS remains a pathway through an appropriate undergraduate degree.
13 | Subject prerequisite vs assumed knowledge - understanding the difference
A persistent source of confusion in student forums is conflating two distinct concepts: a hard prerequisite and assumed knowledge. They have completely different implications for your planning.
Hard prerequisite: The university will not admit you to the programme without this subject. It is a binary gate. No matter how strong your other subjects or grades are, missing this subject closes the door at the point of application.
Assumed knowledge: The university expects you to have covered this material but does not verify it at admission. You may be admitted without it - but the programme is designed assuming you have that background. Arriving without it means you will need to cover the gap yourself, often concurrently with Year 1 modules.
The practical difference: a hard prerequisite is an admissions constraint. Assumed knowledge is a preparation constraint. Missing a hard prerequisite means you cannot apply. Missing assumed knowledge means you may struggle in Year 1.
Which is which - a reference table
Course / Programme
Hard prerequisite (cannot be missing)
Assumed knowledge (gap is survivable but costly)
NUS Medicine / NTU LKCMedicine
H2 Biology, H2 Chemistry, H2 Maths
H2 Physics (not required, but Year 1 biophysics draws on it)
NUS / NTU Engineering (most disciplines)
H2 Maths, H2 Physics (discipline-specific)
H2 Chemistry (useful for materials, chemical engineering modules)
H2 Maths (quantitative modules in Year 1 assume it), H2 Economics
NUS Law / SMU Law
None (grade-based + aptitude test)
GP writing skills, H2 Literature or H2 History (analytical writing habits)
NUS Life Sciences / Biomedical Sciences
H2 Biology or H2 Chemistry
Both Bio and Chem together (most modules assume both)
SMU SCIS (Computing and Information Systems)
H2 Maths
H2 Physics or H2 Econ depending on track
SUTD (Architecture and Engineering)
H2 Maths (most tracks)
H2 Physics, H2 Chemistry
NUS Pharmacy
H2 Chemistry or H2 Biology (at least one)
Both together (first-year biochemistry and pharmaceutics draw on both)
Planning implication: When reading admissions websites, look carefully at whether a subject is listed as a prerequisite (or requirement) versus as recommended (or advised). These are not interchangeable. If the language is ambiguous, contact the admissions office directly to clarify before you finalise your JC combination.
14 | H1 vs H2 level caveats by course
One of the most underappreciated nuances in JC subject planning: for several important course families, H1 Mathematics is not equivalent to H2 Mathematics, and this distinction directly affects your eligibility.
Where H1 Mathematics is sufficient
Business and Accountancy at NUS, NTU, and SMU: H1 Mathematics is generally sufficient for basic admissions eligibility. You will face quantitative adjustment in Year 1, but the admissions gate does not require H2 Maths.
Law at NUS and SMU: Mathematics level is irrelevant - no mathematics prerequisite applies.
Humanities, Social Sciences, Communications, Arts programmes: Mathematics level is generally not part of the admissions requirement.
Where H2 Mathematics is required and H1 is not accepted
Engineering (all disciplines at NUS, NTU, SUTD, SIT): H2 Mathematics is a hard prerequisite. H1 Mathematics does not satisfy this requirement.
Computing and Data Science (NUS SoC, NTU SCSE, SMU SCIS, SUTD): H2 Mathematics is required. H1 Mathematics is not accepted.
Quantitative Finance and Business Analytics double degrees: Any programme combining Business with Computing, Engineering, or quantitative analytics will carry the H2 Mathematics requirement of the more demanding component.
NUS Architecture: H2 Mathematics is required. H1 is not accepted.
The critical planning implication
If you take H1 Mathematics and aim for Engineering, Computing, or Architecture, you are ineligible - regardless of your H2 subject grades. This cannot be resolved by bridging at most institutions. The NUS MA1301 bridging pathway exists for some programmes and is documented at https://eclatinstitute.sg/blog/NUS-No-H2-Maths-MA1301-and-Proficiency-Test-Guide-2026, but it is not universally available and does not apply to engineering programmes at NUS or NTU.
The H1 Mathematics trap: Some students take H1 Mathematics to reduce workload, planning to use the freed capacity to score higher in other H2 subjects. This is a reasonable strategy if your target programmes do not require H2 Mathematics. It is a costly error if your target is Engineering, CS, or Architecture.
If you are considering H1 Mathematics, explicitly verify that every programme on your target list accepts H1 - do not assume.
15 | Hybrid subject combinations - CMEp, HELm, PGEm and university course mapping
Hybrid combinations (often called "hybrid streams" or "cross-stream" combinations) mix subjects from the Science and Arts streams. They are permitted at some JCs and are increasingly taken by students who want subject flexibility. However, they are one of the least well-documented areas in student forums - "I don't know a lot about hybrid streams" is a common thread opener.
What hybrid combinations are
A hybrid combination is one where a student takes H2 subjects from both the Science and Arts stream canonical lists. Examples:
CMEp - Chemistry, Mathematics, Economics (all H2) + Physics at H1. This is a common hybrid for students interested in Chemistry-heavy fields (Chemical Engineering, Pharmacy, Chemistry degrees) alongside Economics or business-adjacent programmes. It is also taken by students who want to signal scientific literacy without committing to a full science stream.
HELm - History, Economics, Literature (all H2) + Mathematics at H1. The inverse: an Arts-dominant combination with a Mathematics component. Keeps some quantitative options open (Business, some IS tracks) while being fully humanities-facing for the core subjects.
PGEm - Physics, Geography, Economics (all H2) + Mathematics at H1 or H2. Less common, often found at JCs offering Geography as an H2.
University course mapping for hybrid combinations
The key principle: university admissions rules look at specific subject titles and levels, not at whether your combination is "hybrid" or "pure stream." Whether CMEp satisfies a prerequisite depends on whether Chemistry at H2 and Mathematics at H2 satisfy that programme's requirement - not on the combination label.
Target programme
CMEp (C, M, E at H2 + P at H1)
HELm (H, E, L at H2 + M at H1)
Medicine (NUS/NTU)
Not eligible - only 1 H2 science (Chemistry); Biology missing
Not eligible - no H2 sciences
Engineering (most disciplines)
Partially - Chem satisfies Chem prereq; but H1 Physics may not satisfy H2 Physics requirement at NTU/SUTD
Not eligible - no H2 Maths, no H2 science
Chemical Engineering
Likely eligible - H2 Chemistry + H2 Maths meets the core prereq (verify per institution)
CMEp is one of the most searched hybrid combinations precisely because students taking it often aspire to medicine. The table above confirms: CMEp has only 1 H2 science (Chemistry). NUS and NTU Medicine require 2 H2 sciences. CMEp is categorically ineligible for NUS/NTU Medicine. This is not a borderline case.
For a student on CMEp who wants to keep medicine as an option, the routes are: add H2 Biology to the combination (making it BCME or BCMEP - verify JC availability), or plan for the Duke-NUS postgraduate MD route through a relevant undergraduate degree.
JC availability of hybrid combinations
Not all JCs offer hybrid combinations. The availability of cross-stream subject pairings depends on each JC's subject combination rules, timetabling, and minimum cohort sizes. Before planning around a hybrid combination, confirm with your target JC that the specific pairing you want is offered.

17 | JC offering considerations
The subject combination that satisfies your target degree prerequisites must also be offered at your JC. A few planning notes:
All 17 JCs and Millennia Institute offer H2 Mathematics, H2 Chemistry, H2 Physics, H2 Biology, and H2 Economics. The standard science and business combinations (PCME, BCME, HELM) are universally available.
H2 Computing is not offered at all JCs. It is not a prerequisite for any computing degree, so its absence does not affect eligibility - but if you want exposure, verify availability at your specific JC.
H2 Art, H2 Music, H2 Theatre Studies are offered at a smaller number of JCs. If these subjects are relevant to your intended programme (architecture portfolio, arts programmes), confirm availability before JAE or direct entry.
H2 Further Mathematics is not offered at all JCs. If you are aiming for scholarship-level profiles in STEM, verify whether your target JC offers FM before you rely on it in your planning.
H2 Knowledge and Inquiry (KI) is a specialised subject available at select JCs (primarily RI). It does not fill a science or maths prerequisite but can differentiate an application for competitive humanities-facing programmes.
For per-JC subject availability, consult your school's subject combination booklet or the MOE/SEAB listings.
18 | When your target has changed after results release
If you receive your A-Level results and find that your subject combination does not meet the prerequisites for your original target degree, your options are:
Check related programmes with different prerequisites. For example, if you missed Medicine prerequisites, NUS Biomedical Sciences or NTU Biological Sciences may still be open.
Review admissions holistically. Some programmes (especially at SIT and SUSS) have more flexible prerequisite requirements. Verify directly.
