L1R4 is the revised five-subject aggregate used for Junior College admission from the 2028 Joint Admissions Exercise. It replaces the previous L1R5 structure by counting one language subject and four relevant subjects instead of one language subject and five relevant subjects.
The change matters to students in the SEC era because it reduces the number of subjects counted while still preserving breadth across Humanities and Mathematics/Science. It also changes the qualifying threshold for JC eligibility and reduces the cap on bonus points.
This guide explains the new JC L1R4, the revised MI L1R4, the 16-point and 20-point thresholds, the subject groups that must be represented, and what Secondary 3 and Secondary 4 learners should do with that information.
The Short Answer: What Is the New JC L1R4?
From the 2028 JAE, JC admission is computed from five subjects: L1 plus four relevant subjects.
- L1: English or Higher Mother Tongue Language.
- R1: one best-scoring Humanities subject.
- R2: one best-scoring Mathematics or Science subject.
- R3: one best-scoring subject from Humanities, Mathematics or Science.
- R4: one additional best-scoring subject.
MOE states that the qualifying threshold for JC eligibility under the revised L1R4 structure is 16 points before bonus points.
Why L1R4 Replaces L1R5
The change reduces the number of subjects counted for JC admission from six to five. MOE’s stated aim is to give students more room to recalibrate curriculum load and spend more time on broader development while still preserving the subject breadth expected for pre-university study.
The structure still requires Humanities and Mathematics/Science representation. So the new system is not simply “take any five subjects”.
The JC Subject Groups
L1 — Language
L1 is English or Higher Mother Tongue Language. This keeps strong language proficiency central to JC admission.
R1 — Humanities
At least one Humanities subject must be represented. This maintains breadth in interpretation, evidence, argument and human-context understanding.
R2 — Mathematics or Science
At least one Mathematics or Science subject must be represented. This maintains quantitative or scientific breadth.
R3 — Humanities, Mathematics or Science
A third relevant subject must come from one of those three broad groups.
R4 — Any Best-Scoring Subject
The fifth counted subject is one additional best-scoring subject.
The 16-Point JC Eligibility Threshold
MOE states that under the revised L1R4 framework, the qualifying threshold for JC eligibility is 16 points before bonus points.
This does not mean every student with 16 points is guaranteed a place in every JC. Posting outcomes still depend on demand, available places and the eventual competition for individual JCs.
Eligibility means you may compete for a place. It does not guarantee the cut-off point of a specific JC.
Bonus Points: The New Cap Is 3
MOE states that the cap on bonus points for JC admission will be lowered from a maximum of four to three points from the 2028 framework.
Students and parents should use the current bonus-point rules for the application year rather than relying on older L1R5 assumptions.

MI also uses an L1R4 aggregate, but the subject-group requirements are revised from 2028 so they align more closely with the breadth expected under the JC framework.
- L1: English or Higher Mother Tongue Language.
- R1: one best-scoring Humanities subject.
- R2: one best-scoring Mathematics or Science subject.
- R3: one best-scoring Humanities, Mathematics or Science subject.
- R4: one additional best-scoring subject.
MOE states that the MI qualifying threshold remains 20 points. The bonus-point cap for MI is aligned with the revised JC cap.
How Full SBB and SEC Fit L1R4
Under Full Subject-Based Banding, students can take subjects at different levels. SEC results therefore may include G1, G2 and G3 subjects.
For admissions calculations, official grade mapping can be used when subjects taken at more demanding levels need to contribute to an aggregate at a reference level. Families should apply only the official mapping rules used by the relevant admissions exercise.
Read the SEC Grade Mapping guide.
What L1R4 Means for Secondary 2 Subject Choice
The revised structure means learners considering JC should preserve enough breadth in upper-secondary subject selection.
- Do not neglect Humanities entirely.
- Do not neglect Mathematics and Science entirely.
- Keep English strong because L1 remains central.
- Choose subjects the learner can sustain rather than maximizing difficulty blindly.
- Check the school’s actual subject offerings and eligibility rules.
A learner should build a portfolio that meets likely pathway requirements while still allowing strong performance.
What L1R4 Means for Secondary 3
Secondary 3 is the year to turn subject choice into stable performance. Learners considering JC should already know which subjects could realistically contribute to L1R4.
- Which Humanities subject is strongest?
- Which Mathematics or Science subject is strongest?
- Which additional relevant subject is likely to be stable?
- Which fifth subject is the best flexible scorer?
- Is English or Higher Mother Tongue the likely L1?
- Are any required subject groups currently fragile?
What L1R4 Means for Secondary 4
In Secondary 4, revision should become selective. The learner does not need every subject to become equally strong if the admission framework counts five subjects, but minimum subject requirements and future A-Level subject choices still matter.
The strategic mistake is to abandon a weaker subject too early without checking whether it is needed for eligibility, JC subject prerequisites, school promotion requirements or another pathway.
A Practical L1R4 Planning Table
- L1: identify English or Higher Mother Tongue.
- R1 Humanities: identify the strongest eligible Humanities subject.
- R2 Math/Science: identify the strongest eligible Mathematics or Science subject.
- R3 HMS: identify the next strongest Humanities/Math/Science subject.
- R4 Any: identify the strongest remaining eligible subject.
- Reserve subjects: identify one or two alternatives if performance changes.
This creates a live planning model rather than a fixed prediction.
Do Not Optimise Only for the Aggregate
A low aggregate is important for admission, but subject choice should also prepare the learner for the academic work after admission.
For example, a learner planning to take H2 Mathematics should care about mathematical readiness, not merely whether Mathematics helps the aggregate. A learner interested in science-heavy routes should think about Science depth. A learner considering Humanities-heavy routes should protect strong reading and writing.
L1R4 and Course Fit
The best JC or MI is not automatically the one with the lowest historical cut-off. Fit includes school culture, subject combinations, travel, CCA, support, pace and the learner’s academic interests.
The L1R4 aggregate opens the door. The learner still has to choose which door makes sense.
Common Parent Mistakes
- Assuming 16 points guarantees a particular JC.
- Treating bonus points as guaranteed before checking current rules.
- Dropping Humanities too aggressively despite R1 requirements.
- Neglecting Mathematics/Science despite R2 requirements.
- Choosing the hardest possible subject combination only for status.
- Using old L1R5 rules for the 2028 JAE.
- Focusing only on aggregate and ignoring likely A-Level subject prerequisites.

- Check minimum admission and subject prerequisites.
- Build reserve subjects in case performance changes.
- Review the plan after each major school assessment.
Frequently Asked Questions
What is the JC L1R4 threshold from 2028?
MOE states that the qualifying threshold is 16 points before bonus points.
What is the MI threshold?
MOE states that MI retains a qualifying L1R4 threshold of 20 points.
How many bonus points can be used for JC admission?
MOE has announced that the cap is reduced to three points under the revised framework.
Does L1R4 mean only five subjects matter in Secondary 4?
No. Other subjects can still matter for minimum entry requirements, future subject prerequisites, alternative pathways and the learner’s overall academic options.
L1R4: Fewer Counted Subjects, Not Narrower Thinking
The revised JC admission framework counts five subjects instead of six, but it deliberately preserves breadth across language, Humanities and Mathematics/Science.
Use L1R4 as a planning framework, not as an excuse to ignore the rest of the learner’s education. The best Secondary 3 and Secondary 4 strategy is to know which subjects matter, keep the required groups stable, and build enough depth to thrive after admission.
