## 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.
