How Are Degree Grades Calculated?
UK degree grades are calculated using a credit-weighted average of your module marks, with different years contributing different amounts to your final classification. Here is exactly how it works.
The Basic Formula
Your degree classification is determined by your overall weighted average percentage. The calculation has two steps:
- Calculate each year's average: Sum (module mark × module credits) for all modules in a year, then divide by the total credits for that year.
- Apply year weightings: Multiply each year's average by its weighting, then add them together.
Worked Example
A student with a 40/60 weighting (Year 2 = 40%, Year 3 = 60%):
Year 2 Modules
| Module | Credits | Mark |
|---|---|---|
| Psychology Research Methods | 30 | 62% |
| Cognitive Psychology | 30 | 68% |
| Social Psychology | 30 | 55% |
| Developmental Psychology | 30 | 71% |
Year 2 Average: (62×30 + 68×30 + 55×30 + 71×30) ÷ 120 = 64.0%
Year 3 Modules
| Module | Credits | Mark |
|---|---|---|
| Dissertation | 40 | 72% |
| Advanced Research Methods | 20 | 65% |
| Clinical Psychology | 30 | 68% |
| Neuropsychology | 30 | 70% |
Year 3 Average: (72×40 + 65×20 + 68×30 + 70×30) ÷ 120 = 69.3%
Final Calculation
Overall = (64.0 × 0.40) + (69.3 × 0.60) = 25.6 + 41.6 = 67.2%
This gives a 2:1 (Upper Second Class Honours).

Classification Boundaries
| Classification | Overall Average Required |
|---|---|
| First Class Honours (1st) | 70% and above |
| Upper Second Class Honours (2:1) | 60% to 69% |
| Lower Second Class Honours (2:2) | 50% to 59% |
| Third Class Honours (3rd) | 40% to 49% |
| Fail | Below 40% |
Year Weightings
Different universities weight years differently. Year 1 typically does not count towards classification (you must pass to progress). Common schemes for Year 2 and Year 3:
| Scheme | Year 2 | Year 3 |
|---|---|---|
| 40/60 | 40% | 60% |
| 33/67 | 33.33% | 66.67% |
| 25/75 | 25% | 75% |
| 0/100 | 0% | 100% |
Some universities also include Year 1 with a small weighting (e.g. 10/30/60) or use different rules for Scottish four-year degrees. Always check your university's programme specification.
Credits Explained
Each module carries a credit value reflecting its size. A standard UK undergraduate year is 120 credits. Modules are typically 10, 15, 20, 30, or 40 credits. Higher-credit modules have more influence on your year average because the calculation is credit-weighted.
Frequently Asked Questions
Does Year 1 count towards my degree grade?
At most UK universities, Year 1 does not count towards your final classification. You need to pass Year 1 to progress to Year 2, but only Years 2 and 3 typically count. Some universities use a small Year 1 weighting (e.g. 10%), so check your programme specification.
What are borderline cases?
If your average is close to a classification boundary (e.g. 68-69% for a First), some universities apply special rules. These may consider the proportion of credits at the higher level, your final-year average, or your dissertation mark. Policies vary widely between institutions.
Do all modules count equally?
No. Modules are weighted by their credit value. A 40-credit dissertation has twice the influence of a 20-credit module on your year average. Within a year, higher-credit modules matter more.
How do retakes affect my grade?
If you retake a failed module, most universities cap the retake mark at the pass threshold (typically 40%). This capped mark is used in your average calculation. Some universities have different rules for first-sit and resit marks.
Is there rounding?
Most UK universities do not round up to the next classification boundary. An average of 69.9% is typically classified as a 2:1, not a First. Some universities round to one or two decimal places during calculation but apply boundaries strictly.
Can I calculate my grade during the year?
Yes. Use our Degree Classification Calculator with the marks you have so far. You can also use our What Do I Need for a First? calculator to see what you need on remaining modules.
What about Scottish universities?
Scottish undergraduate degrees are typically four years. The calculation principles are the same (credit-weighted averages with year weightings), but the specific year weightings differ. Common Scottish schemes weight years 3 and 4, or all four years with varying contributions.
Where can I find my university's exact rules?
Check your university's programme specification, student handbook, or academic regulations (usually available on the university website or intranet). Your department or academic adviser can also clarify.
