Singapore GPA
& grading scale
Quick answer: Major Singapore universities (NUS, NTU) grade on a 5.0 grade-point scale (A+/A = 5.0); the overall result is the credit-weighted GPA (formerly CAP). D (1.0) is the minimum pass. Because it is a 5.0 scale, converting to a US GPA requires rescaling.

How the Singapore grading scale works
Major Singapore universities (NUS, NTU) grade on a 5.0 grade-point scale (A+/A = 5.0); the overall result is the credit-weighted GPA (formerly CAP). D (1.0) is the minimum pass. Because it is a 5.0 scale, converting to a US GPA requires rescaling.
Grade scale
| Grade / range | Meaning (≈ US) |
|---|---|
| A+ / A | 5.0 |
| A- | 4.5 |
| B+ / B / B- | 4.0 / 3.5 / 3.0 |
| C+ / C | 2.5 / 2.0 |
| D+ / D | 1.5 / 1.0 |
| F | 0.0 |
Formula
GPA = sum(grade point x units) / sum(units) on 5.0. US approximation: (native / 5.0) x 4.0, or map letters directly (A/A+ -> 4.0, A- -> 3.7 ...).
Worked example
A native 4.5/5.0 -> (4.5 / 5.0) x 4.0 = 3.6 on the US 4.0 scale.
