From the 2028 Joint Admissions Exercise (JAE), junior college admission in Singapore shifts from L1R5 (six subjects) to L1R4 (five subjects), with a qualifying threshold of 16 points and a reduced bonus point cap of 3 — meaning each counted subject now carries 20% of the aggregate instead of 16.7%, and consistency across subjects matters more than ever. This change was announced by MOE as part of the broader Full Subject-Based Banding reforms.
At Ancourage Academy, Gabriel advises secondary students on subject combination strategy and JC preparation. The L1R4 change is not merely a scoring adjustment — it fundamentally alters which subjects matter most and how students should allocate their study time across Sec 3 and Sec 4.
What L1R4 Means: The Scoring Breakdown
L1R4 stands for 1 Language + 4 Relevant subjects, totalling 5 subjects in the admission aggregate — down from 6 under L1R5.
| Component | What Counts | Subject Category |
|---|---|---|
| L1 | Best language subject | G3 English Language or Higher Mother Tongue Language |
| R1 | Best Humanities subject | History, Geography, Literature, Economics, or other Humanities |
| R2 | Best Maths or Science subject | E-Maths, A-Maths, Physics, Chemistry, Biology, or Combined Science |
| R3 | Best Humanities or Maths/Science subject | One more from either Humanities or Maths/Science |
| R4 | Best remaining subject | Any G3 subject with no category restriction |
The system automatically selects the student’s best-performing subjects in each slot. Applied subjects such as Design and Technology (D&T) and Nutrition and Food Science (NFS) are not counted in the L1R4 aggregate.
L1R5 vs L1R4: Key Differences
The change is more than dropping one subject — it shifts the weight of each subject and alters the strategic calculation for subject combinations.
| Aspect | L1R5 (Until 2027 JAE) | L1R4 (From 2028 JAE) |
|---|---|---|
| Total subjects in aggregate | 6 | 5 |
| Per-subject weight | ~16.7% | 20% |
| JC qualifying threshold | ≤ 20 points | ≤ 16 points |
| MI qualifying threshold | ≤ 20 points | ≤ 20 points (unchanged) |
| Bonus point cap | 4 (6 with LEP) | 3 (5 with LEP) |
| Category constraints | 1 Humanities + 1 Maths/Science + 3 flexible | 1 Humanities + 1 Maths/Science + 1 either + 1 any |

Who Is Affected: The Timeline
The first cohort affected is students who are in Secondary 2 in 2025 — they will sit the new SEC examination in 2027 and enter the 2028 JAE using L1R4.
- Sec 3–4 in 2025: Not affected. They sit O-Levels in 2025–2026 and use L1R5 for the 2026–2027 JAE.
- Sec 2 in 2025: First affected cohort. They choose Sec 3 subject combinations in late 2025 with L1R4 in mind.
- Sec 1 and below in 2025: All subsequent cohorts use L1R4.
Minimum Grade Requirements for JC Entry
Beyond the L1R4 aggregate threshold, students must meet minimum grades in three compulsory subjects to qualify for JC.
| Subject | Minimum Grade Required |
|---|---|
| G3 English Language | A1 to C6 (grade 6) |
| G3 Mathematics | A1 to D7 (grade 7) |
| G3 Mother Tongue Language | A1 to D7 (grade 7) |
| G3 Higher MTL | A1 to E8 |
| G2 MTL | Grades 1 to 5 |
These are threshold requirements, not aggregate components. A student who scores D7 in Mathematics meets the minimum but should aim considerably higher for a competitive aggregate at top JCs.
How Bonus Points Change
The maximum bonus points decrease from 4 to 3 under L1R4, making each bonus point proportionally more impactful.
- CCA achievement: Excellent CCA = 2 points; Good CCA = 1 point
- Higher Mother Tongue: A1–C6 in English AND a passing grade in Higher MTL = 2 points
- Chinese/Malay Special Programme: A1–C6 grade = 2 points
- Affiliated JC: Choosing an affiliated JC = 2 points
- Language Elective Programme (LEP): 2 extra points beyond the cap
The categories remain the same, but the cap decreases. A student with excellent CCA (2 points) and affiliated JC (2 points) previously received 4 bonus points; under L1R4, this is capped at 3. Students should not assume the same bonus point total as older siblings or seniors.
Strategic Implications for Students
The shift to L1R4 changes how students should approach subject selection, study allocation, and exam strategy from Sec 3 onward.
- Consistency over breadth: With each subject carrying 20% of the aggregate, a single weak grade has a larger drag effect. A student scoring A1, A1, A2, A2, C5 under L1R4 has an aggregate of 11 — the same student with those first four subjects and an additional A2 under L1R5 would have had an aggregate of 9. The weakest subject matters more when there are fewer subjects to dilute it.
- Humanities cannot be neglected: R1 must be a Humanities subject. Students who focus exclusively on Maths and Science while neglecting History, Geography, or Literature will have a weak R1 that drags down the aggregate. Targeted Humanities preparation is no longer optional.
- A-Maths remains strategically valuable: A-Maths can fill the R2 (Maths/Science) slot, freeing E-Maths for R3 or R4. Strong maths students can place both mathematics subjects in their top 5.
- Combined vs Pure Science recalibration: Under L1R4, the question is not “should I take Pure Sciences?” but “will Pure Sciences be among my top 5 subjects?” A student who scores B4 in Pure Chemistry might have been better served by an A2 in Combined Science that counts in the aggregate.
- Fewer subjects, deeper study: Students taking 7 subjects instead of 8 can allocate more time per subject. Under L1R4, this trade-off is more defensible than before because only 5 subjects count.
Impact on JC Cut-Off Points
Individual JC cut-off points will be recalculated under L1R4 and cannot be directly compared to historical L1R5 cut-offs.
The qualifying ceiling for any JC admission is 16 points (down from 20 under L1R5), but competitive JCs will have cut-offs considerably lower. Since the new system automatically drops each student’s weakest subject, many students’ raw aggregates will improve. However, because this applies to all students equally, the relative ranking — and therefore the cut-off points — will adjust accordingly.
Parents should expect MOE to publish new indicative cut-off points after the first L1R4 cohort enters JC in 2028. Until then, comparing your child’s projected L1R4 score against L1R5 cut-offs is not meaningful.
How Ancourage Academy Prepares Students for L1R4
Ancourage Academy’s secondary programmes are structured around the principle that consistency across subjects is more valuable than exceptional performance in one subject at the expense of others, using the ESB methodology to target each student’s weakest counted subject.
In small classes of 3–6 students, Ancourage Academy’s tutors identify each student’s weakest counted subject and allocate targeted attention to bring it up — because under L1R4, raising a C5 to a B3 in one subject has a larger aggregate impact than raising an A2 to an A1 in another.
Ancourage Academy offers O-Level preparation in E-Maths, A-Maths, English, Science, and Chinese at both Bishan and Woodlands. WhatsApp Ancourage Academy to discuss your child’s L1R4 strategy.
Common Questions About L1R4 JC Admissions
When does L1R4 start?
L1R4 takes effect from the 2028 JAE. The first cohort affected is students in Secondary 2 in 2025, who will sit the SEC examination in 2027 and apply to JC in 2028. Students currently in Sec 3 or Sec 4 continue under L1R5.
How many subjects does my child need for JC under L1R4?
The L1R4 aggregate counts 5 subjects: 1 language + 4 relevant subjects. However, students still take 7–8 subjects at O-Level/SEC. The scoring system automatically selects the best 5. Students need a gross aggregate of 16 points or fewer (before bonus point deductions) to qualify for JC.
Does A-Maths still matter under L1R4?
Yes. A-Maths can count as the R2 (Maths/Science) subject and is particularly valuable for students aiming for H2 Mathematics at JC. A strong A-Maths grade gives the student two mathematics subjects competing for aggregate slots, increasing the chances of a low aggregate.
Will JC cut-off points change?
Yes. Cut-off points will be recalculated under L1R4 and cannot be compared directly to historical L1R5 cut-offs. Since L1R4 drops every student’s weakest subject, raw aggregates will generally be lower, but relative rankings remain similar. MOE will publish new indicative cut-offs after the 2028 JAE.
What about Millennia Institute?
MI admission also shifts to L1R4 from 2028, but the qualifying threshold remains at 20 points (unchanged from L1R5). The same L1, R1–R4 subject category rules apply. MI students need at least 3 of their R subjects to follow the same combination rules as JC applicants.
