Portugal vs Singapore Grading System

How does the Portugal grading system work?

Portuguese universities use a 0–20 scale inherited from the French tradition. Pass mark is 10. Grades of 18–20 are rarely awarded.

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.

Do Portugal and Singapore 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 Portugal

As with other 20-point systems, the top of the Portuguese scale is barely used: marks above 17 are uncommon and 20 is effectively unattainable, so a 15 or 16 represents a strong degree rather than the mediocre 75–80% it resembles when converted arithmetically. The honours labels at 18 and above are worth stating on an application precisely because the number alone does not communicate how rare they are.

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.

Will a grade from Portugal get you into Singapore?

Singapore universities typically ask for 3.50 / 5 for a taught master's — a one-to-two-year postgraduate degree made mostly of classes. On Portugal's scale that is roughly 13.3–14.6 / 20 (Bom (Good)). Singapore states this as an honours class rather than a CAP figure — Honours (Merit) / Second Class and above, which begins at 3.5 on the 5.0 CAP scale modelled here. NTU's published bar is looser still ("at least a good Bachelor degree"). Both universities stress that meeting the minimum does not imply admission, because selection is competitive against the rest of the applicant pool.

Muito Bom (18–20) → approximately 4.0 GPA.

What goes wrong converting grades from Portugal to Singapore?

The pass marks differ — 10.0 in Portugal against 2.00 in Singapore — so the two scales have different usable ranges and the middle of one is not the middle of the other.

Mistakes specific to Portugal grades

• Converting a 20-point mark to a percentage by multiplying by five. A 15/20 is a good Portuguese degree; "75%" reads as unremarkable in the US.
• Expecting the top of the scale to be reachable. Above 18 is very rare, which compresses the meaningful range considerably.
• Omitting the honours designation where you hold one — it is quota-like in practice and communicates more than the mark.

What should you do next, applying from Portugal to Singapore?

1. Check the course, not the country. Entry requirements are set per programme and revised every cycle. The 3.50 / 5 above is the typical bar, not a guarantee — selective courses ask for more.
2. Check whether an evaluation is even required. Unlike the US and Canada, Singapore universities commonly assess foreign transcripts in-house. Confirm on the course page before paying for a report you may not need.
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 Portugal grading works · How Singapore grading works

What do these grading terms mean?

Percentage scale

A 0–100 marking scale — but the numbers are not comparable across countries: 70% is an outstanding result in the UK and a modest one in India.

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.

Grade compression

Where a marking culture rarely uses the top of its own scale, so the highest grades anyone actually earns sit well below the theoretical maximum.

Credits / credit hours

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

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.

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.
