Weighted average

About this tool

Why use this tool

The weighted average calculator is useful for UK students juggling GCSEs, A-Levels, BTEC coursework and university module marks. Unlike the pass/fail simplicity of some qualifications, most UK courses combine coursework, controlled assessments and final exams in different proportions — an English Literature A-Level might weight the exam at 80 % and non-exam assessment at 20 %. At university, each module contributes to the degree classification based on credit weighting (typically 15, 20 or 30 CATS credits per module) and year weighting set by each institution.

How it works

Weighted average = Σ(mark × weight) / Σ(weights). For UK universities, most institutions apply Year 2 : Year 3 weighting of 40:60 or 33:67 for a three-year Bachelor's degree, with Year 1 excluded from the final classification (still required to progress). Degree classifications follow the standard bands: First (70+), Upper Second/2:1 (60–69), Lower Second/2:2 (50–59), Third (40–49). QAA (Quality Assurance Agency) benchmarks these standards across UK HE providers.

Real example

A final-year undergraduate has Year 2 average of 62 % and Year 3 average of 68 %. With a 40:60 weighting: (62 × 0.4) + (68 × 0.6) = 24.8 + 40.8 = 65.6 %. This falls in the 2:1 band. Had the Year 3 average been 70 %, the calculation would give 66.8 % — still a 2:1, but many institutions apply borderline rules pushing candidates within 2 % of a First upward.

Practical tips

Check your university's degree classification algorithm — some use module-by-module weighting rather than year averages, others use the "best 80 % of credits". Russell Group universities publish their exam boards' rules online. For A-Levels, UCAS Tariff points still influence some university offers, but most now list grade requirements directly (AAB, ABB). Plan revision time proportionally to weighting: a 30-credit dissertation worth 25 % of Year 3 deserves more hours than a 10-credit seminar module. The Office for Students (OfS) monitors classification inflation.

Disclaimer

Actual degree classification depends on your institution's specific regulations, including borderline rules, condonement, discretion of the exam board, and treatment of resits. Refer to your programme handbook and the QAA UK Quality Code. This calculator is indicative only and does not represent an official mark from your awarding body (Ofqual, JCQ or your university registry).

Frequently asked questions

How is a weighted average calculated for UK coursework?⌄
Each assessment is multiplied by its weighting percentage, the results are summed, then divided by the total weighting. For example, coursework worth 40% scored at 65 and an exam worth 60% scored at 55 gives (65×40 + 55×60) / 100 = 59. Our calculator handles any mix of weightings, whether expressed as percentages or credits.
How are UK degree classifications determined?⌄
A First-class honours requires an average of 70% or above, an Upper Second (2:1) requires 60-69%, a Lower Second (2:2) requires 50-59%, and a Third requires 40-49%. Most universities weight the final year most heavily, commonly 30:70 or 40:60 across the second and third years. Exact weighting rules are set in each institution's assessment regulations.
How do UCAS points work for A-levels?⌄
UCAS tariff points convert qualifications into a common score: an A* at A-level is worth 56 points, an A is 48, a B is 40, a C is 32, and so on. Universities may quote offers in grades, points, or both. BTECs, Scottish Highers and the Extended Project Qualification also carry tariff points that can count toward an offer.
What are credits in a UK degree and how do they weight my average?⌄
A full-time undergraduate year is normally 120 credits, so a bachelor's degree totals 360 credits. Individual modules are usually 15, 20 or 30 credits, and their contribution to your year average is proportional to their credit value. A 30-credit dissertation therefore influences your final classification twice as much as a 15-credit module.
What is condonement or compensation at UK universities?⌄
Condonement allows a student to pass an award despite marginally failing a limited number of credits, provided the overall average is sufficient. Rules differ by institution but typically permit up to 20 or 30 credits with marks in the 30-39% band. Core or professionally accredited modules are usually excluded from condonement.
