> How MOE computes the ELR2B2 net aggregate for polytechnic diploma courses, the net aggregate limits for O-Level students and from 2028, how CCA bonus points work, and how B2 changes to a G2 equivalent grade from 2028.

## The formula

The ELR2B2 net aggregate for a polytechnic diploma course is:

*English Language (EL) + 2 Relevant subjects (R1, R2) + 2 Best subjects (B1, B2), minus CCA bonus points*

A lower score is better. Each course uses one of four aggregate types, ELR2B2-A, B, C or D, which differ in the relevant subjects. Grades count as A1 = 1 up to F9 = 9.

## The limits

| Admission | Net aggregate must not exceed | Diploma in Nursing (ELR2B2-C) |
| --- | --- | --- |
| O-Level students, 2027 JAE | 26 | 28 |
| From 2028 admission | 22 | 24 |

You must also meet the minimum entry requirements of the course. The limit only decides whether you can apply: each course's own net aggregate range changes with applicants and their choices every year.

## What changes for B2 from 2028

EL, R1, R2 and B1 still use the G3 grade. B2, the 2nd best-scoring subject, can be taken at G2 or G3 and uses a **G2 equivalent grade**:

| G3 / O-Level grade | G2 / N(A)-Level grade |
| --- | --- |
| A1 to B3 | 1 |
| B4 to C6 | 2 |
| D7 | 3 |
| E8 | 4 |

G3 grade 9 and G2 grades 5 and 6 cannot be used. If two G3 subjects fill B1 and B2, the better grade goes to B1 and the other is mapped for B2. MOE's example: G3 Chinese A2 and G3 Physics B4 give A2 for B1 and G2 grade 2 for B2. If you took the same subject at both levels for B2, the better G2 equivalent grade is used.

## CCA bonus points

For graduates of national secondary schools, an **Excellent** CCA grade (A1 or A2) gives 2 points and a **Good** grade (B3 to C6) gives 1 point. They are subtracted from the gross aggregate to give the net aggregate used for eligibility and posting. Private candidates and current or former students of a JC, MI or ITE keep the bonus if they have the grade.

## What you cannot use

You cannot use the grades of both Higher Mother Tongue and Mother Tongue of the same language. For example, in ELR2B2-C, if Higher Chinese is B1, Chinese cannot be B2. The Merit and Pass grades of Mother Tongue 'B' Syllabus cannot be used either.

## What this guide does not cover

The calculator adds the five grades you choose. It does not pick your relevant or best subjects: use MOE's subject list for the aggregate type of your course. It also does not cover a course's minimum entry requirements, ITE routes or the Polytechnic Foundation Programme.

## Common mistakes

- **Using the wrong limit.** O-Level students and 2028 admission have different limits.
- **Forgetting the B2 mapping.** From 2028, B2 uses the G2 equivalent grade.
- **Using both Mother Tongue levels.** Only one of Higher Mother Tongue and Mother Tongue of a language can count.

## Which tool for what

- [JC aggregate calculator](https://toolsg.com/en/jc-aggregate-calculator): the L1R5 and L1R4 aggregates for JC and MI.
- [PSLE score calculator](https://toolsg.com/en/psle-score-calculator): the PSLE Achievement Level score.

## Frequently asked questions

**What is the ELR2B2 net aggregate limit for polytechnics?**

For the O-Level cohort applying through the 2027 JAE, the ELR2B2 net aggregate must not exceed 26, or 28 for the Diploma in Nursing (ELR2B2-C). From 2028 admission the limits are 22 and 24.

**What does ELR2B2 stand for?**

English Language, 2 Relevant subjects and 2 Best subjects. The net aggregate is the sum of those five grades minus CCA bonus points.

**How many bonus points does CCA give?**

An Excellent CCA grade (A1 or A2) gives 2 points and a Good grade (B3 to C6) gives 1 point. They are subtracted from the gross aggregate.

**What changes for B2 from 2028?**

The second best subject can be taken at G2 or G3 and is computed with a G2 equivalent grade. G3 grades A1 to B3 become 1, B4 to C6 become 2, D7 becomes 3 and E8 becomes 4. G3 grade 9 and G2 grades 5 and 6 cannot be used.

**Is my data sent anywhere?**

No. The calculation runs in your browser, so the grades you enter are not sent to a server by this tool.
