How It Works

UK degree classifications are calculated using a weighted average of your module marks. Each module contributes to your final degree class based on both the mark you achieved and the credit value of that module.

The formula is straightforward:

For example, if you scored 65% in a 20-credit module and 70% in a 10-credit module, your weighted average would be ((65 × 20) + (70 × 10)) ÷ 30 = 66.67%.

Your weighted average then determines your degree classification:

Classification	Weighted Average	Common Name
First Class Honours	70% and above	First
Upper Second Class	60% to 69%	2:1
Lower Second Class	50% to 59%	2:2
Third Class Honours	40% to 49%	Third
Fail	Below 40%	Ordinary Degree or Fail

Which Years Count Towards Your Degree?

Most UK universities follow a standard weighting system, but it varies by institution. Here’s what’s typical:

For three-year degrees, first year usually doesn’t count. You need to pass, but the marks don’t contribute to your final classification. Second year typically counts for 33% and final year for 67%, though some universities weight them equally at 50% each.

For four-year degrees (like integrated masters or Scottish degrees), the weighting spreads differently. Check your student handbook or ask your academic advisor.

What If I Failed a Module?

Failed modules (below 40%) still count in your weighted average unless you successfully resit them. If you resit and pass, the resit mark (usually capped at 40%) replaces the original fail.

This is where things get harsh. A single failed 20-credit module can drop your average by several percentage points, potentially knocking you down a classification.

Resit Mark Rules

Most universities cap resit marks at the pass threshold (40%). Even if you score 75% on a resit, it’ll only count as 40% in your weighted average. Some universities are more generous with first attempts at reassessments, so check the rules.

Quick Reference: Sample Degree Calculations

Year 2 Average	Year 3 Average	Weighted Result (33%/67%)	Classification
65%	72%	69.69%	2:1
68%	71%	70.01%	First
55%	63%	60.36%	2:1
58%	58%	58.00%	2:2
62%	48%	52.62%	2:2

Edge Cases and Tricky Situations

What if I’m on 69.5%?

This depends entirely on your university’s rounding policy. Some round 69.5% up to 70% (giving you a First), others don’t. Many use a borderline classification process where academic boards review students within 1-2% of a boundary.

Do all modules carry equal weight?

No. A 40-credit dissertation counts twice as much as a 20-credit module. That’s why the weighted average formula multiplies each mark by its credit value. You can’t just average your percentages.

What about placement years?

Sandwich year placements usually don’t count towards your degree classification. You need to pass them, but they’re marked as pass/fail. The same applies to most study abroad years, though exceptions exist.

Can I still get a First if I failed a module?

Technically yes, if you resit and the rest of your marks are high enough to pull your weighted average above 70%. But it’s mathematically tough. A failed 20-credit module that gets capped at 40% after a resit will drag down your average significantly.

Why Your Degree Class Actually Matters

Lots of graduate schemes and further study programs set minimum requirements. A 2:1 is often the baseline for competitive jobs, especially in law, finance, consulting, and civil service roles. Some PhD programs won’t consider applications below a 2:1.

That said, work experience, skills, and references matter too. A 2:2 with strong internships can beat a First with nothing else on the CV. But you need to know where you stand so you can plan accordingly.

Frequently Asked Questions

Does my first year count?

At most UK universities, no. First year is usually pass/fail. You need to pass to progress, but the marks don’t count towards your final degree classification. Always verify this with your university.

How accurate is this calculator?

It uses the standard weighted average formula that UK universities use. But individual universities may have specific rules around borderline classifications, grade profiles, or discretionary marks. Use this as a guide, not a guarantee.

What’s a good degree classification?

A 2:1 (60% to 69%) is considered good and meets most graduate job requirements. A First (70%+) is excellent and opens doors to competitive programs. A 2:2 (50% to 59%) is respectable but may limit some options. Context matters, your subject, university, and what you did beyond grades all count.

Can I calculate my classification mid-year?

Yes, but remember you’re working with incomplete data. Add your confirmed marks and estimate your pending results. It’ll give you a projection, but it’s not final until all marks are in.

What if my university uses a different weighting system?

Some universities weight years differently (e.g., 40% year 2, 60% year 3). This calculator uses credit-based weighting, which works for most institutions. If your university uses year-based weighting, you’ll need to calculate each year’s average separately, then apply the year weights manually.

Should I include modules I’m currently taking?

Only if you have confirmed marks. If you’re predicting results, add them separately and note that your classification is an estimate until those marks are official.

Understanding Credit Values

UK modules are measured in credits. A standard full-time year is 120 credits. Most modules are 10, 15, 20, or 40 credits. Your dissertation or final project is often 40 credits (double-weighted).

Credits matter because they determine how much each module affects your final average. Acing a 40-credit module moves your average much more than acing a 10-credit one.

What Happens If You’re On The Borderline?

Many universities have discretionary rules for students who fall within 1-2% of a classification boundary. Academic boards may review your profile, looking at things like: the number of modules in the higher classification, whether you showed improvement over time, extenuating circumstances.

This isn’t automatic. You can’t bank on it. But it does mean that 69.4% isn’t necessarily a death sentence for a First, and 59.6% might still get you a 2:1 depending on your university’s specific regulations.

The safest approach is to aim clearly above the boundary you want, not rely on discretionary bumps.
