O-Level Points Calculator
Calculate your L1R5 and L1R4 aggregate scores for JC and polytechnic admission.
What are O-Level Points?
O-Level points are the aggregate scores used for post-secondary admission in Singapore. L1R5 (1 Language + 5 Relevant subjects) is used for Junior College entry, while L1R4 (1 Language + 4 Relevant subjects) is used for polytechnic admission. Each grade converts to points (A1=1 to F9=9), and lower totals are better.

Quick Reference
- • Grade-to-points: A1=1, A2=2, B3=3, B4=4, C5=5, C6=6, D7=7, E8=8, F9=9
- • L1R5 range: 6 (best) to 54 — used for JC admission
- • Top JCs (Raffles, Hwa Chong, Victoria): L1R5 cut-off around 4-7 points
- • Bonus points (CCA, affiliation) can reduce aggregate by up to 4 points
How It Works
The O-Level aggregate score is calculated by adding up the points from your best qualifying subjects. For JC admission, you need L1R5 (1 Language + 5 Relevant subjects). For polytechnic, you need L1R4 (1 Language + 4 Relevant subjects).
Each O-Level grade corresponds to a point value: A1 = 1, A2 = 2, B3 = 3, B4 = 4, C5 = 5, C6 = 6, D7 = 7, E8 = 8, F9 = 9. The lower your aggregate, the better your score.
Bonus points from CCA (up to 2 points), affiliation (2 points), and other categories can further reduce your aggregate by up to 4 points total.

Frequently Asked Questions
What is L1R5 and how is it calculated?expand_more
L1R5 stands for 1 Language + 5 Relevant subjects. It is used for Junior College (JC) admission. You take your best grade in an L1 language subject and add the points from your best 5 relevant subjects across the R1-R5 categories (Humanities, Math/Science, etc.). Lower aggregate scores are better.
What is L1R4 used for?expand_more
L1R4 (1 Language + 4 Relevant subjects) is the aggregate score used for polytechnic admission. It follows the same principle as L1R5 but with one fewer subject, making the maximum score lower.
How do O-Level grades convert to points?expand_more
O-Level grades convert to points as follows: A1 = 1 point, A2 = 2 points, B3 = 3 points, B4 = 4 points, C5 = 5 points, C6 = 6 points, D7 = 7 points, E8 = 8 points, F9 = 9 points. Lower point totals are better.
What are the typical JC cut-off points?expand_more
JC cut-off points vary each year based on cohort performance. As a general guide, top JCs like Raffles, Hwa Chong, and Victoria may have cut-offs around 4-7 points for L1R5. Mid-tier JCs range from 8-14 points, while other JCs may accept up to 20 points. Check MOE for the latest official cut-off points.
Can CCA and bonus points reduce my aggregate?expand_more
Yes, bonus points can reduce your L1R5 or L1R4 aggregate by up to 4 points. You can get 2 bonus points for CCA (grades A or B), 2 points for affiliating to a JC from its affiliated secondary school, and other bonus categories. The minimum reduced aggregate cannot go below 4 for L1R5.
