The bands are the same; everything else varies
Every university checked uses the same bands. What differs is how the final mark is computed, rounded, and treated at the borderline.
| Classification | Final mark |
|---|---|
| First Class Honours (1st) | 70 and above |
| Upper Second (2:1) | 60–69 |
| Lower Second (2:2) | 50–59 |
| Third (3rd) | 40–49 |
| Fail / no honours | Below 40 |
Two exceptions. Integrated masters have no Third: Fail is 49 and below. The module pass mark is 40 at undergraduate levels (50 at level 7). Professional programmes — Medicine, Dentistry, Veterinary Sciences at Bristol; MBChB, MChD/BChD at Leeds — are excluded from the standard model. Postgraduate labels (Distinction, Merit, Pass) are a different system and are out of scope here.
How the classification is determined
- Each module mark is weighted by its credit value within its year. At Bristol, a 20-credit unit is one-sixth of a 120-credit year.
- Year marks are combined using the university’s (or programme’s) year weighting. First year normally contributes 0.
- The combined mark is rounded per that university’s rule — Bristol rounds to the nearest integer before the borderline check; Leeds Iteration B keeps one decimal place.
- The rounded mark is mapped to the bands above.
- If the mark falls in the borderline zone, a second rule (profile test) may raise the class. The borderline rule is not an automatic upgrade and differs by university.
- The exam board retains discretion for exceptional circumstances, accreditation constraints, must-pass units, and credit requirements. A calculator cannot model board discretion.
Named weightings — none is a UK standard
There is no universal UK year weighting. Every weighting on this page is a labelled example from a named university. Never treat one as “the UK weighting.”
| Weighting | Years used |
|---|---|
| Bristol — Arts, Law & Social Sciences | Year 2 at 40%, Year 3 at 60% |
| Bristol — Science & Engineering | Year 2 at 25%, Year 3 at 75% |
| Leeds — better of 1:1 or 1:2 | Years 2–3; the university computes both and awards the better result |
| Nottingham — Bachelor’s | Part I at 33%, Part II at 67% |
| Edinburgh — Biological Sciences | Year 3 at 1, Year 4 at 2 (Years 1–2 pre-honours) |
| Edinburgh — Mathematics | Year 3 at 50%, Year 4 at 50% |
| Edinburgh — MMath | Year 3 at 20%, Year 4 at 40%, Year 5 at 40% |
Scotland runs four-year honours degrees (Years 3–4 count). England, Wales, and Northern Ireland typically run three-year degrees (Years 2–3 count). Integrated masters add a fourth or fifth year. The same university can use three different weightings across programmes — Edinburgh alone uses 1:2, 50:50, and 20:40:40.
Borderline rules — all different
| University | Borderline zone | What happens |
|---|---|---|
| Bristol | 68–69, 58–59, 48–49 | Higher class only if at least 50% of rounded unit marks, weighted by credit and year, are at the higher class |
| Leeds | Within 0.5 of a boundary (reported) | Iteration B reportedly lifts such marks automatically — confirm in the current Academic Regulations; this calculator does not award the higher class |
| Edinburgh Biology | Within 2 points below a boundary | Higher class if at least 50% of weighted credits are in the higher class |
| Nottingham, Edinburgh Maths, MMath, Custom | — | No borderline rule modelled; your university’s rule decides near a boundary |
A calculator that silently rounds 68.6 up to a First would be wrong at Bristol (68.6 rounds to 69 → borderline → profile test) and would award a class no calculator should award on its own. Year averages alone cannot decide a profile test — the test needs your individual unit marks.
Worked examples
Bristol Arts 0:40:60. Year 2 at 62, Year 3 at 68: 0.40 × 62 = 24.80; 0.60 × 68 = 40.80; total = 65.60 → rounded to the nearest integer = 66 → 2:1. 66 is not in the 68–69 borderline zone.
Leeds, better of 1:1 vs 1:2. Year 2 at 58, Year 3 at 72: 1:1 → (58 + 72) ÷ 2 = 65.0. 1:2 → (58 + 2 × 72) ÷ 3 = 202 ÷ 3 = 67.3. Better = 67.3 → 2:1. A calculator offering only one Leeds weighting would give the wrong mark.
Edinburgh Biology 1:2, borderline. Year 3 at 68, Year 4 at 70: (68 + 2 × 70) ÷ 3 = 208 ÷ 3 = 69.33. Below 70 but within 2 points → borderline — profile test decides. Year averages alone cannot decide this.
Bristol Science 0:25:75, borderline. Year 2 at 60, Year 3 at 71: 0.25 × 60 = 15.00; 0.75 × 71 = 53.25; total = 68.25 → rounded = 68 → borderline 68–69 → profile test decides.
Credit-weighted year average (illustrative arithmetic). One year, 120 credits: 20-credit module 72; 20-credit module 65; 40-credit dissertation 68; 40-credit module 70: (72 × 20 + 65 × 20 + 68 × 40 + 70 × 40) ÷ 120 = 8,260 ÷ 120 = 68.83. The credit-weighting method is verified (Bristol §30.59, Nottingham); the numbers are illustrative.
What the calculator does not model
- Board discretion. Exam boards decide exceptional circumstances, accreditation constraints, must-pass units, and credit minima.
- Resits and capping. Leeds caps re-assessment at 40; Nottingham uses the original mark for classification; Edinburgh Maths has no resits for honours courses. These rules are mutually different and are not modelled. The calculator assumes first-attempt marks as entered.
- Condonement and compensation. No general UK rule exists. Bristol has its own credit-award and compensation conditions; Edinburgh boards may disregard flagged credits; Leeds uses discretion bands. A failed module is never promised to be condoned.
- Failed modules and credit minima. Leeds requires passing at least 100 credits at each of levels 1, 2, and 3, and the Final Year Project must be passed.
- Rounding beyond the named rule. Bristol rounds to the integer; Leeds keeps one decimal. Other weightings show two decimals; your university’s rounding rule governs.
Common mistakes
- Calling 40/60 “the UK standard.” It is one faculty’s rule at Bristol. Science at the same university uses 25/75.
- Treating a borderline mark as the higher class. 68.6 is not a First until a profile test or board says so.
- Ignoring rounding order. Bristol rounds before the borderline check; rounding after would change the zone.
- Mixing postgraduate labels with undergraduate marks. Distinction and Merit belong to postgraduate taught awards.
- Converting a UK class to a GPA. No verified conversion exists — this site does not convert.
- Assuming Year 1 never matters. It is excluded from the calculation in these examples, but you must still pass it to progress.
