JC Admission Aggregate Calculator Singapore (L1R5 and L1R4)
Work out your L1R5 aggregate for the 2027 JAE, or the L1R4 aggregate from 2028, from your subject grades and bonus points, and see whether you meet the JC cut-off.
MOE changes JC and MI admission from the 2028 JAE.
A1 counts as 1 and F9 as 9.
If you took Higher Mother Tongue, the better of English and Higher Mother Tongue as L1 is used.
Higher Mother Tongue and Mother Tongue of the same language cannot both be used.
Your other subjects
Add up to 8 subjects besides English and Mother Tongue. Leave out Religious Knowledge. The rows start with example grades; replace them with yours. Humanities and Mathematics/Science subjects can be relevant subjects. Applied subjects such as Design and Technology count as Other.
From your CCA record and other categories, as shown in your MOE records. They are capped at the maximum.

Key figures at a glance
How grades count
Each grade counts from A1 = 1 to F9 = 9. The gross aggregate is the sum of the grades used, and the net aggregate is the gross minus bonus points. The admission criteria are set on the gross aggregate; the net aggregate is used for posting.
2027 JAE (O-Level): L1R5
JC admission needs a gross L1R5 of 20 or better across six O-Level subjects.
- L1: English Language or Higher Mother Tongue.
- R5: three relevant subjects, which must be two Mathematics/Science and one Humanities, or the reverse (applied subjects such as Design and Technology, and Nutrition and Food Science are not relevant subjects), plus the two other best-scoring subjects.
- Bonus points: at most 4.
2028 JAE onwards (G3): L1R4
| Part | Subject |
|---|---|
| L1 | English or Higher Mother Tongue |
| R1 | Best Humanities subject |
| R2 | Best Mathematics or Science subject |
| R3 | Best of the Humanities, Mathematics or Science subjects left |
| R4 | Best of any subject left |
A gross L1R4 of 16 or less is needed for JC and 20 or less for MI. With Higher Mother Tongue, the aggregate is worked out with English and with Higher Mother Tongue and the better one is used. Religious Knowledge cannot be one of the best-scoring subjects.
Bonus points are capped at 3, and a Chinese, Malay or Tamil Language Elective Programme place adds 2 more.
Rules that apply to both
- Higher Mother Tongue and Mother Tongue of the same language cannot both be used.
- Minimum grades apply to specific subjects. For 2028: English A1 to C6; Mathematics A1 to D7; Mother Tongue A1 to D7 at G3 (Higher Mother Tongue A1 to E8).
- Polytechnics use ELR2B2: English + 2 relevant subjects + 2 best subjects, net aggregate of 26 or less (28 for Nursing). CCA bonus points: 2 for a CCA grade of A1 or A2, 1 for B3 to C6. This calculator does not cover polytechnics.
Worked example
English 2; Mathematics 1, Chemistry 2, Geography 3, Literature 3, two more subjects 3 and 4; 2 bonus points.
- L1R5 (2027): L1 2 + relevant 1 + 2 + 3 + best two 3 and 3 = 14, net 12.
- L1R4 (2028): L1 2 + R1 3 + R2 1 + R3 2 + R4 3 = 11, net 9.

Frequently asked questions
What is L1R5?
Your first language (English or Higher Mother Tongue) plus five subjects: three relevant subjects (two Mathematics/Science and one Humanities, or the reverse) and your two other best subjects. JC admission in the 2027 JAE needs 20 or better.
What changes in 2028?
JC and MI admission moves to L1R4 with G3 subjects: JC needs 16 or less and MI 20 or less, and one fewer subject is counted.
Is the gross or the net aggregate used for eligibility?
The admission criteria are on the gross aggregate. Bonus points are subtracted to get the net aggregate for posting.
Can I use both Higher Mother Tongue and Mother Tongue?
No. Only one of the two in the same language can be used in the aggregate.
Does this cover polytechnics?
No. Polytechnics use ELR2B2 with relevant subjects set for each aggregate type, which this calculator does not model.
