The UK grading system and degree classes, explained
UK universities mark on a percentage but report final degrees as honours classifications: a First, an Upper Second (2:1), a Lower Second (2:2), a Third, or a Fail. A 70% is an A-grade in the UK — the scale is much more compressed than the American one.
The grades and what they mean
| Class | Percentage | Common name | ≈ US GPA |
|---|---|---|---|
| First (1st) | 70–100 | First-class honours | 3.7–4.0 |
| 2:1 | 60–69 | Upper second-class | 3.3–3.7 |
| 2:2 | 50–59 | Lower second-class | 2.7–3.0 |
| Third (3rd) | 40–49 | Third-class honours | 2.0–2.3 |
| Fail | 0–39 | Below honours | 0.0 |
The pass mark
40% is the pass mark for most undergraduate modules — that earns a Third. Below 40% is a fail. Note that 70% is a First, the top band: UK markers rarely give marks in the 80s or 90s, so a 75 is an exceptional result.
A 2:1 (60%+) is the classification most graduate employers and master's programs ask for.
Converting UK grades to a US GPA
There is no official conversion, but a common guide is: First ≈ 3.7–4.0 GPA, 2:1 ≈ 3.3–3.7, 2:2 ≈ 2.7–3.0, Third ≈ 2.0. Because UK marks top out lower, a First should not be read as 'only 70%' — it is the highest class available.
Why the numbers feel low
In the UK, the full 0–100 range is genuinely used, and 70+ is reserved for the best work. This trips up students used to US percentages, where 90+ is an A. A UK 65 is a strong 2:1, not a 'D'.
