How is a UK degree classification calculated?

Most universities take a credit-weighted average of your module marks for each counting year, then combine those year averages using fixed weightings (for example one-third Year 2 and two-thirds Year 3). The result is compared against the class boundaries: 70 for a First, 60 for a 2:1, 50 for a 2:2 and 40 for a Third.

Does 69.5% count as a First?

It depends on your university. Leeds awards the higher class to averages within 0.5 of a boundary, and UCL's threshold for a First is 69.50. Other universities use a wider borderline zone and look at the spread of your marks instead of rounding.

What is the most common year weighting?

There is no single standard. One-third Year 2 and two-thirds Year 3 (a 1:2 ratio) is common, but 40/60 and 25/75 are also used, and some universities such as UCL give first year a small weighting. Always check your own programme regulations.

Can I still get a First if my second year was a 2:1?

Often, yes. With a 60% second year and a one-third/two-thirds weighting you would need around 75% in final year. Use the degree classification calculator to test your own numbers.

How to Calculate Your Degree Classification (Step-by-Step…

You've handed in the essays. You've survived the exams. Now comes the most stressful part of the degree: the maths.

UK grading isn't "add everything up and divide". You're dealing with credits, year weightings and borderline rules, and every university sets its own. This guide walks through each step with worked numbers, then shows what real universities actually publish.

The class boundaries

Almost every UK university uses the same boundaries for an honours degree:

Classification	Average needed
First-Class Honours (1st)	70% and above
Upper Second-Class (2:1)	60–69%
Lower Second-Class (2:2)	50–59%
Third-Class (3rd)	40–49%
Fail	Below 40%

For example, the University of Leeds publishes its thresholds as 70.0, 60.0, 50.0 and 40.0. 70% may not sound high if you're used to school percentages, but in a UK degree it is a genuinely strong mark.

How common is each result? Across the UK in 2024/25, just under half of classified first degrees were 2:1s and roughly three in ten were Firsts:

Step 1: Work out each year's average (credits matter)

Modules aren't equal. A 40-credit dissertation counts twice as much as a 20-credit module and four times as much as a 10-credit one. So each year's average is a credit-weighted average:

Multiply each module mark by its credits.
Add those totals together.
Divide by the total credits for the year (usually 120).

Worked example: Year 2

Module	Credits	Mark	Mark × credits
Module A	20	62	1,240
Module B	20	58	1,160
Module C	20	65	1,300
Group project	40	60	2,400
Module D	20	55	1,100
Total	120		7,200

Year 2 average = 7,200 ÷ 120 = 60.0

Worked example: Year 3

Module	Credits	Mark	Mark × credits
Dissertation	40	72	2,880
Module E	20	68	1,360
Module F	20	66	1,320
Module G	20	70	1,400
Module H	20	64	1,280
Total	120		8,240

Year 3 average = 8,240 ÷ 120 = 68.7 (to one decimal place)

Notice what the dissertation does: one strong 40-credit mark lifts the whole year.

Step 2: Apply your university's year weighting

On most three-year bachelor's degrees, first year doesn't count towards the class (you just have to pass it; see do first year grades count?). Years 2 and 3 are then combined using a fixed ratio. Using the averages above (Year 2 = 60.0, Year 3 = 68.7):

Weighting (Y2 / Y3)	Calculation	Final average	Class
33% / 67% (1:2)	(60.0 × 1 + 68.7 × 2) ÷ 3	65.8	2:1
40% / 60% (2:3)	60.0 × 0.4 + 68.7 × 0.6	65.2	2:1
25% / 75% (1:3)	60.0 × 0.25 + 68.7 × 0.75	66.5	2:1
50% / 50%	(60.0 + 68.7) ÷ 2	64.3	2:1

Same marks, four different results, a spread of more than two percentage points. That is why you need your university's rule, not a rule of thumb.

What real universities publish

University	How a 3-year bachelor's is weighted	Borderline rule	Source
Leeds	Years 2 and 3 at 1:2 (about 33% / 67%) for students who started in 2022/23 or later	Averages within 0.5 of a boundary get the higher class	Leeds classification guidance
York	Final two years; the standard stage weighting is 2:3 (40% / 60%)	A 2-mark zone below each boundary, where alternative stage weightings are considered	York summary of award rules
UCL	Year means weighted, e.g. 1:3:5 for Years 1, 2 and 3; only the best 90 credits of Years 1 and 2 count	First at 69.50, or at 68.50+ with 70+ in at least half of final-year credits	UCL Academic Manual, classification
Birmingham	Second-year marks worth 25%, final year 75%	Check current regulations	University of Birmingham (2020 statement)

Weightings can differ for integrated master's degrees, placement years and accredited courses. Leeds, for instance, uses 1:2:2 across Years 2, 3 and 4 of an integrated master's. Your programme handbook is the final word.

Step 3: Check the borderline rules

What happens if you land on 69.6%? It depends:

Rounding or a fixed allowance. Leeds awards the higher class if you are within 0.5 of the boundary, and UCL sets its First threshold at 69.50.
Preponderance or "profile" rules. Some universities look at how many of your credits sit in the higher class. Under UCL's rules, 68.50 or above can still earn a First if at least half of your final-year credits are at 70 or more.
A borderline zone with discretion. York considers alternative stage weightings for students within 2 marks of a boundary.

If you're close to a boundary, check whether your rules reward a strong final year, a dissertation or a run of high module marks. That tells you where to focus.

Step 4: Work out what you need next year

Rearrange the formula and you can find the final-year average you need. Assuming a Year 2 average of 60.0:

Weighting (Y2 / Y3)	Final-year average needed for a First (70)	Needed to keep a 2:1 (60)
33% / 67%	75.0	60.0
40% / 60%	76.7	60.0
25% / 75%	73.3	60.0
50% / 50%	80.0	60.0

And for a student who finished Year 2 on a 57 (a 2:2) and wants a 2:1 under a 33% / 67% split: (60 × 3 − 57) ÷ 2 = 61.5 in final year. Very achievable, which is why a weak second year is rarely the end of the story.

The calculator does these "what do I need?" sums for any weighting.

Resits and capped marks

If you fail a module and resit, the resit mark is usually capped at the pass mark. York, for example, used "the best-attempt mark, capped at the pass mark" for awards involving resits in 2023/24, and its bachelor's guidance bases the class on first-attempt marks. A resit can get you through, but it will rarely help your classification. Our university resits guide covers the process.

Quick checklist

Find your programme regulations. Search your university's website for "degree classification" or "rules for award".
Note your credits. A bad mark in a 10-credit module matters far less than one in a 40-credit dissertation.
Note your weighting. Final year usually counts for more.
Know your borderline rule. It tells you whether a high dissertation mark or an extra 0.5 is worth chasing.
Run the numbers. Use the degree classification calculator, then sanity-check with your department if anything looks off.

Planning ahead? Read do first year grades actually count?, and if you need the core texts for next year, check your reading list against second-hand copies before paying full price.
