UK Semester GPA Calculator
Enter your module marks and credits to see your weighted average mark, degree classification, and equivalent 4.0 GPA.
How This Calculator Works
UK universities use a Weighted Average Mark (WAM) rather than a GPA. This calculator computes your WAM by weighting each module’s mark by its credit value, then maps that WAM to the standard UK degree classification scale.
Module Contribution = (Module Mark % / 100) x Module Credits
// Step 2: Sum all contributions and divide by total credits
WAM = (Sum of all Module Contributions / Total Credits) x 100
// Step 3: Look up degree classification
Classification = Scale lookup(WAM)
// Example: 72% (20 credits) + 65% (20 credits) + 68% (20 credits)
WAM = ((0.72 x 20) + (0.65 x 20) + (0.68 x 20)) / 60 x 100
WAM = (14.4 + 13.0 + 13.6) / 60 x 100 = 68.3% = Upper Second 2:1
UK Degree Classification Scale
| Classification | Abbreviated | WAM Range | 4.0 GPA Equiv. | UCAS Points |
|---|---|---|---|---|
| First Class Honours | 1st | 70% and above | 4.0 | N/A (undergraduate) |
| Upper Second Class | 2:1 | 60-69% | 3.3-3.7 | N/A |
| Lower Second Class | 2:2 | 50-59% | 3.0-3.3 | N/A |
| Third Class Honours | 3rd | 40-49% | 2.0-3.0 | N/A |
| Ordinary Degree / Pass | Pass | 35-39% | 1.0-2.0 | N/A |
| Fail | Fail | Below 35% | 0.0 | N/A |
Table of Truth: Common Module Combinations
| Module Marks | Credits | WAM | Classification |
|---|---|---|---|
| 75, 72, 78, 71 | 20 each (80 total) | 74.0% | First Class |
| 68, 65, 70, 63 | 20 each (80 total) | 66.5% | Upper Second 2:1 |
| 62, 58, 60, 64 | 20 each (80 total) | 61.0% | Upper Second 2:1 |
| 55, 52, 58, 50 | 20 each (80 total) | 53.8% | Lower Second 2:2 |
| 45, 48, 42, 50 | 20 each (80 total) | 46.3% | Third Class |
| 72 (40cr), 65 (20cr), 68 (20cr) | Mixed (80 total) | 69.5% | Upper Second 2:1 (close to First) |
How UK Year Weightings Work
Most three-year UK undergraduate degrees do not count Year 1 toward the final classification at all. The reasoning is that Year 1 is a transition year: students are adjusting to university-level study, and it would be unfair to penalise them permanently for a rocky start.
Common weighting patterns
The most widespread structure is 0/33/67, where Year 1 carries no weight, Year 2 contributes one third, and Year 3 contributes two thirds of the final classification. Some universities use 0/40/60, placing slightly more emphasis on Year 2. Others use 10/30/60 or 20/40/40. Integrated Masters degrees may have four years with different splits entirely.
How this affects your strategy
If Year 1 does not count, failing to reach the First boundary in Year 1 has no lasting consequence, provided you pass. Year 2 is the year that matters most after Year 3. A 65% average in Year 2 and 74% in Year 3 produces a better final result than the reverse. Knowing your year weightings helps you prioritise effort appropriately across your degree.
UK GPA vs US GPA: What Your Mark Means Internationally
UK degrees do not use a GPA. When applying to US graduate schools or international employers, you will need to convert. A First Class is generally equivalent to a 4.0, a 2:1 to 3.3-3.7, a 2:2 to 3.0-3.3, and a Third to 2.0-3.0. These are approximate; the exact conversion used by a specific university may differ. For official evaluations, WES (World Education Services) is the most widely accepted service.
