Nigeria vs United Kingdom 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 United Kingdom grading system work?

UK undergraduate degrees use classification bands, not continuous GPA. UK marking is deliberately strict — scores above 80% are rare. A 72% is First Class, equivalent to an A- in the US.

⚠️ UK grades look low compared to other countries. A 72% is an excellent First Class result. Never compare raw UK percentages to US or Indian percentages.

Do Nigeria and the United Kingdom 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 the United Kingdom

UK marking is deliberately compressed at the top, and this catches out almost every applicant from a percentage-marking country. Essays are rarely marked above 80, and a 75 is an outstanding result — the scale is not designed to reach 100. A 72% is an excellent First Class, not a "C". If you come from India, Nigeria or Pakistan and compare percentages directly, you will misread a UK grade as far worse than it is; the safest habit is to think in classifications and ignore the raw number.

Will a grade from Nigeria get you into the United Kingdom?

United Kingdom universities typically ask for 60 / 100 for a taught master's — a one-to-two-year postgraduate degree made mostly of classes. On Nigeria's scale that is roughly 3.31–3.64 / 5 (Second Class Upper (2:1)). A 2:1 (60%+) is the standard requirement for taught master's across Russell Group universities. Cambridge states a 2:1 minimum and notes many of its courses ask for a High 2:1, a First, or a UK master's — hence the First (70%) as the competitive figure. A 2:2 is accepted by some courses, frequently alongside relevant work experience.

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 the United Kingdom?

United Kingdom rarely awards near the top of its own scale — 85 is realistically the ceiling rather than 100 — so a converted result will look lower than you expect even when it is strong.

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 the United Kingdom?

1. Check the course, not the country. Entry requirements are set per programme and revised every cycle. The 60 / 100 above is the typical bar, not a guarantee — selective courses ask for more.
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, United Kingdom 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.
