LLB Degree Classification Calculator UK: How Law Grades Work

Somewhere around the middle of a law degree, someone asks the question everyone is quietly thinking: if I keep getting these marks, what class will I finish with? You can find a generic degree classification calculator in a minute. The problem is that an LLB is not always calculated the way a generic calculator assumes, and the difference can move you across a grade boundary.

This guide explains how LLB classifications are usually worked out, where the rules differ between universities, and how to produce your own estimate from your marks. It also covers what a classification means when you start applying for training contracts.

For the general mechanics of UK classification, start with how degree classification works in the UK. This post focuses on the law-specific wrinkles.

How an LLB is usually classified

Most LLB degrees run for three years in England and Wales, or four if the course includes a placement or a year abroad. Like most UK undergraduate degrees, the final class is based on a weighted average of module marks, with the usual boundaries:

First class: 70% and above
Upper second (2:1): 60% to 69%
Lower second (2:2): 50% to 59%
Third: 40% to 49%

The boundaries are common across the sector, but the calculation underneath them is not. The clearest way to see this is to compare two published schemes. The LSE LLB scheme for 2024/25 bases the classification on marks from all second and third year courses, with the two years weighted equally. Its bands at the bottom of the scale also differ, with Third at 45 to 49 and Pass at 40 to 44. Other universities use unequal splits, such as 40% for year two and 60% for year three, or average individual units rather than whole years. Your own regulations decide which of these applies to you.

Why year weighting can change your class

Imagine two students with identical marks. Year two averages 74 and year three averages 66. This is a hypothetical example, not a real student's record.

Equal weighting of years two and three: (74 + 66) ÷ 2 = 70.0, which is a first.
40% year two, 60% year three: (0.4 × 74) + (0.6 × 66) = 69.2, which is an upper second.

Same marks, different class. The strong year-two student benefits from equal weighting, and the weaker final year counts for more under the 40/60 split. If your average sits near a boundary, the scheme decides the outcome, not the marks alone.

This is why a law calculator needs to ask about the scheme first. A calculator that assumes equal weighting, or one that ignores your year-one marks entirely, will give you a number that looks precise and is wrong for your course.

What a law calculator needs to know

Before you trust any estimate, check these five settings against your university's regulations:

Setting	What to check	Why it matters
Counting years	Which years contribute to the final class	Some schemes exclude year one entirely
Year weighting	Equal, 40/60, or another split	Changes the result when years differ in average
Module weighting	Whether marks are weighted by credits	A 30-credit module should not count the same as a 15-credit one
Half-unit pairing	Whether half-unit courses are paired within a year	Affects how an unbalanced year is averaged
Resits	Whether the latest attempt replaces earlier marks	Some schemes use the latest attempt for each course

The regulations are usually in the academic regulations PDF or the programme handbook. Search for "classification", "weighting" and "calculation". If you cannot find the scheme for your start year, ask the student advice team. Schemes often change between cohorts, and the one that applies is the one you started under.

Working out your own estimate, step by step

Once you know your scheme, the calculation is short:

List your marks by year and module, with the credit value of each module.
Multiply each mark by its credits, then add the results for each counting year.
Divide by the total credits in that year to get a year average.
Apply the year weighting from your scheme to the year averages.
Compare the result with the boundaries, then check whether it falls in your university's borderline zone.

Step 5 matters more than people expect. If you end up within a couple of points below a boundary, your university's borderline policy may apply. The rules for that are covered in borderline degree classification in the UK.

Does your LLB class matter for a training contract?

This is where many law students get anxious, so it is worth being precise. A 2:1 is widely expected by many firms, and some careers guides say a majority of firms ask for it. Other guides point out that candidates with a 2:2 can still secure training contracts, though it is harder. Firms also weigh work experience, the interview, and assessment centres.

The regulator's position is different. The SRA's rules focus on qualifying law degrees and on the qualifying work experience route, rather than setting a minimum classification. Under the SQE route, there is no minimum degree grade: you need a degree or equivalent, pass SQE1 and SQE2, and complete two years of qualifying work experience. I could not find a classification threshold in the material I checked, so confirm the current wording in the SRA handbook before you rely on it.

Practically, the class matters most to employers who screen by it, and less to the regulator. That makes your module choices in years two and three more important, because they feed the weighted average directly. If you are choosing options, the guide to law optional modules in the UK covers how assessment format and grade spread affect your average.

Using a calculator without fooling yourself

A calculator is useful for planning, not for certainty. Keep three cautions in mind:

Use the scheme for your start year. Regulations change, and an older PDF can give you the wrong weights.
Expect rounding and unit pairing to shift results slightly. Your estimate may differ from the official figure by a fraction of a mark.
Treat the official exam board result as final. Exam boards can also apply borderline discretion, which a calculator cannot predict.

If you are a postgraduate deciding whether a masters is worth it, the grading system is different again. The masters degree classification calculator explains how Distinction, Merit and Pass are decided.

Where module-level data fits in

Your class depends on the marks you get, and the marks depend partly on which modules you take. Some law modules have far wider spreads of grades than others, while some cluster tightly. GradeHack is building module-level grade signals for UK law modules from FOI requests, shown as bands rather than raw cohort numbers, so you can see how a module tends to be marked before you choose it. Join the waitlist to be told when access opens.

Used together, the calculator tells you where your average is heading, and the module data helps you choose the options that move it. If you want the broader picture of how year weighting affects a final class, read does year 1 count towards your degree and how final year affects degree classification.

Frequently asked questions

Does an LLB use the same classification bands as other degrees?

Usually yes, at the top: 70 for a first, 60 for a 2:1, 50 for a 2:2 and 40 for a third. Some schemes use different bands at the bottom of the scale, such as separate Pass and Third bands, so check your regulations for the exact cut-offs.

Do first-year marks count towards an LLB?

It depends on the university. Many law schemes count only years two and three towards the final class, while some count year one for progression only. Your regulations will state which years count.

Is a law degree calculator different from a standard one?

Often the maths is the same, but the settings differ. Law schemes may use specific year weightings, unit pairing, or rules about resits. A good calculator lets you choose the scheme rather than assuming one.

Does a 2:1 LLB guarantee a training contract?

No. A 2:1 is often expected by firms, but it does not guarantee a training contract, and a lower class does not rule one out. Applications are assessed on several criteria, and the SQE route sets no minimum degree grade.

Key takeaways

An LLB is classified from a weighted average of counting years, and the weighting differs between universities.
The same marks can produce a different class under equal weighting and a 40/60 split.
Check your scheme for counting years, year weighting, credit weighting, unit pairing and resits before trusting any estimate.
Firms often ask for a 2:1, but the SRA's rules do not set a classification threshold, so confirm current wording in the handbook.
Module choice feeds the average directly, so treat option choices as part of your classification plan.
