Singapore vs United States Grading System

How does the Singapore grading system work?

NUS and NTU use a 5.0 CAP scale. SMU uses a 4.0 GPA. Singaporean degrees are highly regarded internationally.

⚠️ NUS/NTU use 5.0 CAP, SMU uses 4.0 GPA. Check which university issued your degree.

How does the United States grading system work?

US universities use a 4.0 GPA scale as a credit-weighted average. A=4.0, B=3.0, C=2.0, D=1.0, F=0. Plus/minus grades (A-=3.7, B+=3.3) are common.

Do Singapore and the United States mark to the same standard?

No — and it is the difference in marking culture, not the arithmetic, that makes a direct comparison mislead. Here is how each country actually uses its own scale.

What a good grade means in Singapore

Singaporean degrees are highly regarded internationally, and the grading is demanding: NUS and NTU run bell-curve moderation, so grades reflect standing within a strong cohort rather than an absolute mark. That makes a CAP of 4.0 a genuinely good result even though, mapped to US letters, it sits at a B+ rather than an A. The honours class is the signal to lead with abroad, because Highest Distinction and Distinction are understood in Commonwealth terms in a way a raw 5.0-scale number is not.

What a good grade means in the United States

US marking is generous by international standards, and this is the mirror image of the trap that catches Indian and Chinese applicants. A US 3.5 is a good but unremarkable result, held by a large share of graduates from selective institutions — it is not equivalent to a British 3.5-out-of-4-style elite performance. Applying to the UK, an American should expect their GPA to translate to a lower-sounding percentage than instinct suggests, and that is normal rather than a downgrade.

Will a grade from Singapore get you into the United States?

United States universities typically ask for 3.00 / 4 for a taught master's — a one-to-two-year postgraduate degree made mostly of classes. On Singapore's scale that is roughly 3.16–3.83 / 5 (Honours (Merit)). US graduate schools publish a 3.0 minimum near-universally. The competitive figure is the average GPA of admitted applicants across all graduate programmes at UNC Chapel Hill (gradschool.unc.edu/admissions/averagescores/) — a reference point, not a cut-off. Programmes set their own bars above the school minimum, and applicants below 3.0 are usually invited to contact the programme rather than turned away.

For NUS/NTU (5.0 CAP): 4.0–5.0 (Honours HD) → approximately 4.0 US GPA.

What goes wrong converting grades from Singapore to the United States?

The pass marks differ — 2.00 in Singapore against 1.00 in the United States — so the two scales have different usable ranges and the middle of one is not the middle of the other.

Mistakes specific to Singapore grades

• Reading a CAP of 4.0 as equivalent to a US 4.0. On the 5.0 scale it corresponds to roughly a B+ average — a good result, but not a perfect one.
• Quoting a CAP without saying whether the scale is 5.0 (NUS, NTU) or 4.0 (SMU). The two are not interchangeable.
• Omitting the honours class. Highest Distinction and Distinction translate far better internationally than the underlying number.

What should you do next, applying from Singapore to the United States?

1. Check the course, not the country. Entry requirements are set per programme and revised every cycle. The 3.00 / 4 above is the typical bar, not a guarantee — selective courses ask for more.
2. Budget for a credential evaluation. Most United States universities require your transcript assessed by an approved service before they will consider it — roughly $200 and 4–7 weeks. Our WES guide explains which report to order, since choosing the wrong one means paying twice.
3. Get your documents moving early. Universities normally require your transcript sent directly by your institution rather than as a copy from you, which takes longer than most applicants expect.
4. Read both systems in full. How Singapore grading works · How United States grading works

What do these grading terms mean?

CGPA (Cumulative Grade Point Average)

The same idea as a GPA but covering your whole degree rather than one term — the scale differs by country (India 10, Nigeria 5.0, Pakistan 4.0), so the number alone means nothing without its scale.

GPA (Grade Point Average)

The US way of expressing an overall grade, on a 0–4.0 scale where 4.0 is the top — so a 4.0 is roughly what a 90–100% or a First Class would be elsewhere.

Degree classification

A named band your final result falls into — First Class, 2:1, Distinction — used across the UK, Ireland, Nigeria, India and much of the Commonwealth instead of a single number.

Honours degree

A bachelor's degree that includes a higher-level final year or research project — in Australia, South Africa and New Zealand it is often an extra year, and master's entry can depend on it.

Transcript

The official document from your university listing every subject you took and the grade you got — not the same as your degree certificate, and universities abroad want both.

Credits / credit hours

A measure of how much a subject counts toward your degree — bigger subjects carry more credits and pull your average further.
