UK Degree Classifications Explained
A first needs 70%, a 2:1 60%, a 2:2 50% and a third 40% — but how your average is built, and what happens near a boundary, depends on your university. Here is what is common and what to check.

The four classes
| Class | Weighted average |
|---|---|
| First-class honours (1st) | 70% and above |
| Upper second-class honours (2:1) | 60–69% |
| Lower second-class honours (2:2) | 50–59% |
| Third-class honours (3rd) | 40–49% |
These bands are used almost everywhere in the UK; see, for example, the University of Bristol’s guide to degree classification. Below 40% the result is a fail, though some universities award an ordinary or pass degree without honours.
How the average is built
Your final average combines the marks of your modules, weighted twice: by credits within each year and by a year weighting across years. Typical patterns:
| Pattern | Year 1 | Year 2 | Year 3 |
|---|---|---|---|
| Two-year weighting (1 : 2) | 0% | 33% | 67% |
| Three-year weighting | 10% | 30% | 60% |
| Equal weight | 0% | 50% | 50% |
The University of Manchester publishes the first two patterns as “Option 1” and “Option 2” in its undergraduate degree regulations. Your own regulations may differ, and integrated master’s degrees usually add a fourth year. A worked example is on the UK degree calculator page.
Borderline rules
Many universities look again at students whose average falls just under a boundary. Swansea, for instance, considers students within 2% of a boundary; Manchester publishes a “boundary zone” of 68.0–69.9 for a first; UCL adds criteria based on the share of final-year credits marked in the higher class. The details vary, so treat a result 1–2 marks below a boundary as “possible” rather than certain, and read your own regulations.
Worked example
Suppose your Year 2 modules were marked 61, 66 and 58, and your Year 3 modules 68, 72 and 63, all worth 40 credits, and your university weights Year 2 : Year 3 as 1 : 2.
| Step | Calculation | Result |
|---|---|---|
| Year 2 average | (61 + 66 + 58) ÷ 3 | 61.67% |
| Year 3 average | (68 + 72 + 63) ÷ 3 | 67.67% |
| Weighted average | (61.67 × 1 + 67.67 × 2) ÷ 3 | 65.67% |
| Class | 60–69% | 2:1 |
Two strong Year 3 modules lifted the result by about four marks compared with Year 2 alone — which is why the heavier final-year weighting matters so much.
Why Year 1 often does not count
In many degrees Year 1 must be passed but is not included in the classification, which is why a bad first year can be recovered. Others weight it lightly (for example 10%). Check before you stop worrying about it.
How to improve your classification
- Aim at the heavy modules. A 40-credit dissertation moves your average twice as much as a 20-credit module.
- Use the weighting. If the final year counts for two thirds, extra effort there pays more than a perfect Year 2.
- Look at your profile. If you are close to a boundary, the share of credits already in the higher class may decide a borderline case.
- Ask early. Your personal tutor or the programme office can tell you which rules — discounting, best credits, borderline — apply to you.
Comparing with other countries
UK marks are famously “lower” than in many other systems: 70% is already a top-class result, and few students score above 80%. Never compare a UK percentage directly with an Indian or Chinese one. When you need to express a UK result abroad, use the conversion the receiving institution publishes, or an official evaluation — and see the guide to converting grades for applications.
What a 2:1 means in practice
A 2:1 is the usual minimum requirement for many graduate schemes and for entry to master’s programmes, but requirements differ widely, and some employers and programmes ask for a 2:2 or look at your profile instead. Always check the entry criteria of the job or course you want.
If your final year is still in progress
Use the “final year isn’t finished” option in the UK degree calculator to see which average you need across the final year for each class under your weighting — a good way to set realistic targets for your dissertation and exams.
Frequently asked questions
What percentage do I need for a 2:1?
A weighted average of 60% to 69%.
Do all universities use the same weighting?
No. Each university sets its own year weightings and borderline rules. They are in the academic regulations, usually a section called “classification of awards”.
Is a first really 70%?
Yes, 70% or more is a first at nearly every UK university, though many also use borderline rules for averages slightly below 70.
Do resit marks count?
Usually at a capped value (often the pass mark). Check your regulations.
