The UK grading scale explained
What the classifications mean, what separates each band in practice, and why a 70 is a very good mark rather than a mediocre one.
The UK grading scale confuses almost everyone who did not grow up with it, and plenty who did. It runs to 100 but is not designed to reach it, and the numbers mean something quite different from a percentage of correct answers.
UK degree classifications
| Mark | Classification | Common name |
|---|---|---|
| 70 to 100 | First Class Honours | a First |
| 60 to 69 | Upper Second Class Honours | a 2:1 |
| 50 to 59 | Lower Second Class Honours | a 2:2 |
| 40 to 49 | Third Class Honours | a Third |
| Below 40 | Fail |
A First Class degree is less rare than many students assume. In 2024/25, 30 percent of first degrees awarded in the UK were Firsts, according to HESA.
How your final degree classification is worked out
Your classification is not an average of every mark you have received. Each university applies its own rules, often called the degree algorithm, so your programme regulations are the only reliable source for your degree.
Which years count
On a three year degree in England, Wales or Northern Ireland, first year marks usually do not count, and the second and third years are weighted. A 2017 review by Universities UK and GuildHE found that 84 percent of the 98 universities it surveyed weighted those years somewhere between 50/50 and 20/80, so the final year almost always counts at least as much as the second.
| Weighting (second/third year) | Second year average | Third year average | Final average |
|---|---|---|---|
| 50/50 | 64 | 72 | 68.0, a 2:1 |
| 33/67 | 64 | 72 | 69.3, borderline |
| 20/80 | 64 | 72 | 70.4, a First |
That is why a strong final year matters so much, and why a weak second year is rarely fatal.
Scottish honours degrees usually take four years, and the classification normally draws on the third and fourth years. Integrated master's degrees such as the MEng and MSci are classified like bachelor's degrees, as a First, 2:1, 2:2 or Third.
Borderline marks and what to check
Most universities look again at averages just below a boundary, usually within one or two percentage points. A common rule, known as preponderance, awards the higher class when a set share of your counted credits already sits in the higher band, so a final average of 69 can still become a First. Check these in your regulations:
- Which modules count, and how credits weight them
- How the average is rounded, such as whether 69.5 becomes 70
- The borderline zone, and whether an exam board decides
- Whether resit marks are capped, often at the pass mark
- For a master's, how much the dissertation counts
Master's grading is different
| Mark | Classification |
|---|---|
| 70 and above | Distinction |
| 60 to 69 | Merit |
| 50 to 59 | Pass |
| Below 50 | Fail |
The pass threshold moves from 40 to 50. A mark of 45 that would have passed at undergraduate level fails a master's module, which catches out a surprising number of students in their first term.
Why the scale stops around 80
In a system marking correct answers, 100 is achievable. UK academic marking assesses the quality of an argument, and there is no ceiling on how good an argument could be. The top of the range is therefore reserved rather than used.
- 70 to 79. The normal First. Strong analysis, wide reading, clear argument.
- 80 to 89. Uncommon. Original thinking, near-publishable in places.
- 90 and above. Rare enough that many academics never award one.
If you are used to a system where 90 is expected, this takes adjusting to. A 72 is not a disappointing B. It is a First. If you need to explain your marks to a university or employer abroad, our guide to converting UK grades to GPA gives the equivalents in common use.
What separates the bands on the UK grading scale
Marking criteria vary, but the underlying progression is remarkably consistent across UK institutions.
Third (40 to 49): understanding shown
You have grasped the material and can restate it. Coverage is patchy, sources are thin, and the argument is mostly assertion.
2:2 (50 to 59): accurate description
Sound understanding, described correctly, with reasonable sources. The weakness is almost always the same: the work reports what others have said without doing anything with it. Structure is usually sound and referencing present but inconsistent.
2:1 (60 to 69): analysis and argument
The step up is evaluation. Sources are compared rather than listed, limitations are acknowledged, and the essay argues a position rather than surveying a topic. Referencing is accurate and consistent. This is the band most students reach and the most common degree classification in the UK.
First (70 and above): independent thinking
Everything in a 2:1, plus something of your own: an unexpected connection, a challenge to a dominant reading, a genuinely critical treatment of the evidence. The writing is precise enough that the argument is never in doubt.
The 2:2 to 2:1 gap, which is where most students sit
Ten marks, and usually one habit. Compare how the same source gets used.
2:2 treatment
Ahmed (2024) found that attrition rates were high in adolescent trials. This shows that attrition is a problem in this area.
2:1 treatment
Ahmed (2024) reports high attrition, though the study drew exclusively on clinical samples. Whether the same pattern holds in community settings is untested, which limits how far the finding can inform school-based programmes.
Same source, same length. The second evaluates the evidence rather than repeating it, and that difference sustained across an essay is worth a classification. Our guide tocritical evaluation shows how to build that habit.
Reading your feedback properly
Marker comments map onto the bands more directly than most students realise.
| Comment | What it means |
|---|---|
| "Too descriptive" | You are in 2:2 territory. Evaluate, do not report. |
| "Needs more critical analysis" | The same message, phrased differently. |
| "Unclear" or "doesn't flow" | Expression is obscuring the argument, whatever its quality. |
| "More engagement with the literature" | Too few sources, or too few beyond the reading list. |
| "Good, but assertion needs support" | Claims are uncited. Often the only thing between 68 and 72. |
"Too descriptive" is the most common comment in UK marking and the most actionable. It is not telling you to write more. It is telling you to do more with what you already have.
Comments about flow usually point to the shape of the argument rather than the sentences, which our guide to structuring an essay covers.

Frequently asked questions
The UK university grading system marks undergraduate work out of 100 and groups it into classifications: 70 and above is a First, 60 to 69 an Upper Second (2:1), 50 to 59 a Lower Second (2:2), and 40 to 49 a Third. Below 40 is normally a fail.
Yes. A First begins at 70 and the scale is not designed to run to 100. Marks above 80 are uncommon and above 90 rare, because the top of the range is reserved for work approaching publishable standard.
Ten marks, and usually one thing: analysis. A 2:2 typically shows sound understanding described accurately. A 2:1 does something with that understanding, evaluating sources and building an argument rather than reporting.
Different bands: 70 and above is a Distinction, 60 to 69 a Merit, and 50 to 59 a Pass. The pass threshold is 50 rather than 40, so a mark that would pass comfortably at undergraduate level can fail a master’s module.
From a weighted average of the modules that count, usually the second and third year marks on a three year degree, with the final year weighted at least as heavily. Most universities also have a borderline rule for averages just below a boundary. Your programme regulations set the exact method.
