L1R5 Score 2026: How It's Calculated & JC Cut-Off Points (Full Table)

Every O-Level student in Singapore learns two things about L1R5 within five minutes of getting their results: lower is better, and the difference between an 8 and a 10 decides which junior college they attend. What most students don't fully understand — until they're sitting with a parent at the kitchen table on release night — is exactly which six subjects count, how bonus points rescue a mid-range aggregate, and why some JCs that look far out of reach are actually one CCA grade away.

L1R5 is a score that compresses your two years of upper secondary into a single number, and that number controls the next 18 months of your education. This is how it works.

How is L1R5 calculated?

L1R5 is the sum of grade points from six specific O-Level subjects, selected in a fixed order from your result slip. Lower totals are better.

The six slots are:

• L1 — one First Language. Either English Language at grade 1–6, or Higher Mother Tongue at grade A–C (converted to English Language grade equivalents for the sum).
• R1 and R2 — two Relevant subjects. "Relevant" depends on the JC course you're applying to. For Science courses: typically Math and one Science. For Arts courses: often Humanities and English Literature.
• Remaining 3 — your best three other subjects that weren't used for L1 and R1/R2.

Each O-Level grade converts to a fixed point value:

O-Level Grade	L1R5 Points
A1	1
A2	2
B3	3
B4	4
C5	5
C6	6
D7	7
E8	8
F9	9

The minimum possible raw L1R5 is 6 — six A1s across the six counted subjects. A student who scores A1 in English, A1 in Math, A1 in Physics, A1 in Chemistry, A1 in History, and A1 in Geography lands at 6 before any bonuses apply. The maximum L1R5 still considered for JC admission sits around 20, beyond which most students route to polytechnic.

One critical rule: the six subjects must be your best valid combination. If Biology scored B3 and Geography scored A2, the aggregator uses Geography — subjects auto-sort to minimise your total.

Our O-Level Points Calculator runs this sorting automatically, including bonus points, so you see the net aggregate JCs will actually see on your application.

What L1R5 do I need for top JCs?

Top junior colleges in Singapore cluster their cut-offs tightly between 6 and 12 for the 2026 intake. The table below shows indicative ranges — MOE publishes official cut-offs after each admission round, and the numbers drift by one to two points year to year.

Junior College	Indicative L1R5 Cut-Off (2026)	Tier
Raffles Institution (JC)	6–7	Top
Hwa Chong Institution (JC)	6–7	Top
Victoria JC	9–10	Upper
National JC	9–11	Upper
Temasek JC	10–11	Upper
Eunoia JC	10–12	Upper
Anglo-Chinese JC	10–12	Upper
Nanyang JC	11–12	Upper
St. Andrew's JC	12–14	Mid
Catholic JC	13–15	Mid
Serangoon JC	15–17	Entry
Jurong Pioneer JC	16–19	Entry

The cut-off is the lowest net L1R5 that secured admission in the most recent intake. If Raffles' cut-off is 7, it means every student admitted had 7 or lower after bonuses. A raw score of 8 with -1 CCA bonus hits the 7 threshold exactly and competes against other 7-scorers for remaining places.

Course type matters. Science courses typically carry tighter cut-offs at the same JC than Arts courses — more applicants, fewer seats. A student targeting H2 Chemistry at VJC faces a slightly tougher cut-off than a student targeting H2 Literature at the same school.

Does CCA count toward L1R5?

CCA does not enter the L1R5 sum, but it directly deducts from your total through the bonus point system — which is why strong CCA involvement matters even if it doesn't show up as a graded subject on your certificate.

CCA grades are awarded at the end of secondary four based on participation, leadership, and performance:

• A1 CCA grade — awarded for high-level participation, often combined with leadership or competition achievement. Deducts 1 point from L1R5.
• A2 CCA grade — awarded for consistent participation and moderate achievement. Deducts 1 point.
• B3 and below — no CCA bonus.

A student who scored A1 in CCA through sustained sports captaincy or arts leadership walks into their JC application with an effective L1R5 one point lower than their raw aggregate. This single point moves a 9 to an 8, or a 7 to a 6 — in cut-off terms, a full JC tier.

What's the difference between L1R4 and L1R5?

L1R4 and L1R5 are two different aggregates used for two different post-secondary routes, and the distinction matters because confusing them has tanked more than one application.

• L1R5 — the JC aggregate. Six subjects, used for junior college admission. Still active and official.
• L1R4 — an older polytechnic aggregate. Five subjects. Effectively obsolete — polytechnic admission today uses the ELR2B2 aggregate, which weights English, two Relevant subjects, and two Best subjects based on the poly course applied for.

Students aiming for JC track their L1R5. Students aiming for poly track their ELR2B2. The two numbers are calculated from the same result slip but select different subjects and apply different rules, so a strong L1R5 doesn't automatically mean a strong ELR2B2.

For students undecided between JC and poly on results day, calculating both aggregates is essential. Our O-Level Points Calculator shows both side-by-side. If L1R5 is 12 and ELR2B2 is 7, the strong poly aggregate may point to a higher-tier polytechnic course than a mid-tier JC — and the income outcome over 10 years is non-obvious.

How does the bonus point system work?

The bonus point system deducts from your raw L1R5 after the six subjects are summed, giving students with strong CCA participation and high Mother Tongue proficiency a structural advantage at JC admission.

The four main bonus categories:

• CCA grade A1 or A2 — deducts 1 point.
• Higher Mother Tongue at Distinction / Merit — deducts 2 points at Distinction, 1 point at Merit.
• Mother Tongue B or English Language at A1/A2 when not used as L1 — deducts 1 point.
• VIA / CIP commitment at national level — case-by-case, rarely granted without formal MOE-recognised programmes.

The practical maximum bonus is -4 points, but most students who qualify for bonuses land at -1 or -2. A combined -3 requires Higher Mother Tongue Distinction plus A1 CCA plus a secondary language at A1/A2 — a rare profile.

Worked example — a student with raw L1R5 of 10:

Component	Value
Raw L1R5	10
CCA grade A1	-1
Higher Mother Tongue Distinction	-2
Net L1R5 for admission	7

A raw 10 becomes a net 7 — moving the student from a mid-tier JC target into contention for top-tier JCs. This is why MOE preserves the bonus system despite the complexity: it rewards sustained co-curricular commitment and bilingual proficiency, which aren't captured by academic grades alone.

Some JCs cap bonuses at specific thresholds for their most competitive courses. Students applying to the H3 programme at Raffles, for instance, may find bonus points excluded from subject-specific considerations even where they apply to baseline admission. Read each JC's admission guide before assuming full bonuses transfer.

One further nuance: bonus points apply to the headline L1R5 aggregate for JC admission, but they do not transfer to polytechnic ELR2B2 calculations. A student sitting on a raw L1R5 of 12 with -2 bonuses (net 10) and an ELR2B2 of 8 will be assessed by JCs on the 10 and by polytechnics on the 8 — two different numbers from the same result slip, each with its own bonus logic. This is why students undecided between routes should calculate both aggregates before JAE submissions and treat them as independent decisions, not two views of the same score.

Bottom line

L1R5 is one number, but the decisions behind it stretch across four years of secondary schooling — subject combinations, CCA commitment, Mother Tongue choices, and the relentless effort to pull a grade from C6 up to B4. On results day, your raw aggregate and your net aggregate will differ by one to four points, and that gap decides whether Raffles, Hwa Chong, VJC, or ACJC is a realistic target.

Before JAE submissions, run the full calculation once for every JC you're considering — both raw and net, factoring in each JC's treatment of bonus points — and compare against the latest published cut-offs. A 9 with -2 bonuses is a 7, and a 7 opens doors a 9 never would. Use our O-Level Points Calculator to verify the sum before you lock in your JAE choices.
