UK Degree Classification Boundaries

This reference page explains how UK undergraduate degrees are classified, with a credit-weighted average calculator so you can estimate your classification from your module marks. UK degrees are graded on a percentage scale and grouped into four classes. Enter each module's mark and its credit weight to see your weighted average, then read it against the boundaries below.

Class Common name Mark (%)
First 1st 70 and above
Upper second 2:1 60–69
Lower second 2:2 50–59
Third 3rd 40–49
Fail below 40

The formula

Weighted average = Σ(mark × credits) ÷ Σ(credits)

UK classifications are based on a credit-weighted average of your module marks, usually across the final year(s) — universities differ in exactly which years and modules count and how borderline cases are handled. Multiply each mark by its module credits, sum, and divide by total credits to estimate the average, then compare against the class boundaries.

Worked example

Three modules: 68% (30 credits), 72% (30) and a dissertation 65% (60).

  • Weighted total = 68×30 + 72×30 + 65×60 = 2040 + 2160 + 3900 = 8100
  • Total credits = 30 + 30 + 60 = 120
  • Average = 8100 ÷ 120 = 67.5% → an Upper Second (2:1).

Source & caveat: the 70/60/50/40 class boundaries are the standard UK honours degree classifications used across UK universities. Each university sets its own exact classification algorithm (which years count, weighting, and borderline/discretion rules) — always confirm with your own institution's regulations, as they change.

Frequently asked questions

Is a First always 70%+?
The 70% boundary for a First is standard across UK universities, but the way the overall average is calculated (year weighting, best-modules rules, borderline discretion) varies — check your university's classification policy.
What is a 2:1 worth?
An Upper Second (2:1) sits at 60–69% and is the most commonly awarded class; many graduate schemes ask for a 2:1 or above.
Does every year count equally?
Usually not. Many UK universities weight later years more heavily (for example 40:60 or 25:75 across final years). Enter marks for the years your programme counts.
