Credits are the weights
A UK academic year is usually 120 credits, split unevenly across modules — 30-credit cores, 15-credit options, a 30- or 40-credit dissertation. Your year average is thecredit-weighted mean: each mark times its credits, summed, divided by credits counted. With the defaults above, the marked modules give (66×30 + 61×30 + 72×15) ÷ 75 = 65.2% — mid-2:1 — with 45 credits still to come. A simple unweighted average of the same marks would say 66.3%, a full point off; at a boundary, that's the difference between an exam-board review and none.
The remaining-credits table, explained
Leaving a module's mark blank tells the calculator it's still to be sat, and turns the page into a planner. The required average over remaining credits is (target × total credits − marks banked) ÷ remaining credits. From the defaults — 65.2% banked over 75 credits, 45 credits left — a First needs (70×120 − 4890) ÷ 45 = 78% across the dissertation and final option, while locking the 2:1 needs just 51.3%. That asymmetry is the honest picture most students need in January: the 2:1 is nearly safe, the First costs sustained top-band work. The same inverse logic drives our degree classification calculator at the year level and thefinal grade calculator at the exam level.
UK marks don't read like percentages elsewhere
| Mark | What it means in the UK |
|---|---|
| 80%+ | Exceptional — rare outside mathematical subjects |
| 70–79% | First-class work |
| 60–69% | 2:1 — the most common good-honours band |
| 50–59% | 2:2 |
| 40–49% | Third / bare pass territory |
Because essay marking compresses toward the middle, moving an average even two points takes real work — and explains why exam boards run borderline reviews rather than treating 69.2% as simply "not 70". Watch your handbook for module rules that change the arithmetic: condonable fails, capped resits, and "best 100 of 120 credits" discount rules all shift the effective weighting. Where they exist, this calculator's plain weighted average is your conservative baseline. For anything non-modular — coursework percentages within one module, say — the weighted average calculator handles arbitrary weights.
Frequently asked questions
How do I calculate my weighted module average?
Multiply each module's mark by its credits, add them up, and divide by the credits counted. A 65% in a 30-credit module and a 72% in a 15-credit module average (65×30 + 72×15) ÷ 45 = 67.3% — closer to the 30-credit mark, because credits are the weights.
What average do I need in my remaining modules for a First?
Required average = (70 × total credits − marks already banked) ÷ remaining credits, where banked marks are each completed module's mark × credits. If you're at 66% with 80 of 120 credits done, the remaining 40 credits need (70×120 − 66×80) ÷ 40 = 78%. This calculator does it for every classification at once — just leave unfinished modules' marks blank.
Do all modules count equally towards my year average?
No — a 30-credit dissertation moves your average twice as hard as a 15-credit option. UK years are typically 120 credits, and exam boards compute the credit-weighted mean, not the simple mean. Some programmes also discount the lowest-weighted module or apply preponderance rules, so check your handbook.
Is 65% a good university mark in the UK?
Yes — UK marking runs lower than US percentages. 65% sits mid-2:1, 70%+ is First-class work, and marks above 80 are rare in essay subjects. Never read UK percentages on a US letter scale; a 68% UK average is an excellent result, not a D.
