Nigeria vs South Korea Grading System

How does the Nigeria grading system work?

Nigerian universities use a 5.0 CGPA scale — not 4.0. First Class Honours requires 4.50–5.00 CGPA.

⚠️ Nigerian universities use a 5.0 scale, NOT 4.0. A 4.5/5.0 is First Class on the Nigerian scale — do not read it as a 4.5 on a 4.0 scale.

How does the South Korea grading system work?

South Korean universities use either a 4.5 or 4.0 GPA scale — 4.5 is most common. Always check your transcript to confirm which applies.

⚠️ South Korean universities use 4.5 OR 4.0 scales. Check your transcript carefully.

Do Nigeria and South Korea 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 Nigeria

Nigerian classification is strict, and it travels better than most applicants expect. A First Class is genuinely rare, and Cambridge's own equivalence table treats a Nigerian First (CGPA 4.5/5, or 70%) as matching a UK First — independent confirmation from a named institution that the classification is understood abroad. A 2:1 is a solid, competitive result for master's applications across the UK, Ireland and Australia, and you should present it as such rather than apologising for the number.

What a good grade means in South Korea

Korean grading is competitive rather than lenient: many universities operate relative grading, capping the share of a class that can receive an A regardless of absolute performance. That makes a high GPA harder to earn than the numbers suggest and means small differences between students can reflect cohort competition rather than ability. A 3.5 on the 4.5 scale is a respectable result; treating it as "3.5 out of 4.0" both overstates it arithmetically and understates the effort behind it.

Will a grade from Nigeria get you into South Korea?

We do not yet hold published entry requirements for South Korea, so we do not compare your grade against a bar we cannot cite. The conversion above still tells you how your result reads in South Korea terms.

WES maps Nigerian class of degree using classification bands. First Class (4.5–5.0) → approximately 3.7–4.0 US GPA.

What goes wrong converting grades from Nigeria to South Korea?

The pass marks differ — 1.50 in Nigeria against 2.00 in South Korea — so the two scales have different usable ranges and the middle of one is not the middle of the other.

Mistakes specific to Nigeria grades

• Letting a university read your CGPA against a 4.0 scale. Always write "4.20 on a 5.0 scale" — never the bare number.
• Converting a percentage as though it were a CGPA. A Nigerian 72% is a First Class; entered into a 5.0 CGPA field it becomes meaningless.
• Assuming your degree certificate or NYSC discharge is enough. Evaluators want the academic transcript, which is a different document.

What should you do next, applying from Nigeria to South Korea?

1. Check the course, not the country. Entry requirements are set per programme and revised every cycle. We hold no published national bar for this destination, so the course page is the only figure that binds.
2. Confirm which scale your transcript uses. Nigeria awards grades on more than one scale (CGPA (5.0), Percentage (0–100)), and the same number means different things on each. Pick the matching one in the converter before you trust the result.
3. Check whether an evaluation is even required. Unlike the US and Canada, South Korea universities commonly assess foreign transcripts in-house. Confirm on the course page before paying for a report you may not need.
4. Get your documents moving early. WES requires the academic transcript sent directly by your university, plus the degree certificate or a statement of result. Nigerian institutions are often slow to dispatch these, and that delay is the most common cause of missed application deadlines from Nigeria — start months earlier than feels necessary. Check your transcript states the CGPA scale explicitly; if it does not, ask for a covering letter that does.

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.

First Class Honours

The top degree classification, awarded to a small minority of graduates — usually 70%+ in the UK and Ireland, or a CGPA of 4.50+ on Nigeria's 5.0 scale.

2:1 (Upper Second Class)

The second-highest degree class, and the grade most UK and Irish master's courses ask for — usually 60–69%.

Credential evaluation

A paid report from an approved company that restates your foreign qualification in local terms, which many US and Canadian universities require before they will assess you.
