How to get a first class degree at UK university

A first-class degree in the UK is the thing people talk about but don't really explain how to get. Your school might have told you it's about "working hard". Your parents might think it's genetic. Your university course handbook will tell you it's a mark above 70%.

None of these are wrong, exactly. But they're missing the part that actually matters: getting a first is almost entirely about the one decision your university leaves up to you.

That decision is which modules you take.

We've spent the last 18 months pulling module-level grade distribution data from UK universities via Freedom of Information requests. And one pattern is completely consistent: students who get firsts didn't necessarily work harder than their peers. They made smarter choices about which modules to take.

Here's the framework.

Understand what "first" actually means

Before you can aim for a first, you need to know what you're aiming at.

A first-class degree sits above 70%. But universities vary on whether that's 70%, 70.5%, or 71% — and they vary on which years count toward your average. Most universities weight your final year heavily (typically 50–70% of your overall classification), which means you can limp through year 2 and still graduate with a first if you nail year 3.

A few universities include year 1 in the calculation (usually weighted at 10–20%). Most don't. This matters more than you'd think — if year 1 counts, you need to front-load your effort; if it doesn't, you have permission to treat it as a learning year.

Check your university's regulations document right now. Search for "classification" or "weighting". Write the numbers down. This is the foundation of every decision that follows.

The module choice paradox

Here's what the FOI data reveals: two students on the same degree, same subject, same university, can graduate with radically different classifications depending solely on which optional modules they picked.

Some modules run distributions where 40–50% of students get a first. Others run distributions where 10–15% get a first. The module code is the dominant variable — more so than student ability, more so than how many hours you spend in the library.

Most students don't see this. Universities don't publish module-level distributions. So you end up choosing modules based on:

• Whether they clash with your lunch plans
• What your mate is taking
• Which lecturer seems nice
• Whether it "sounds interesting"

None of these is a good heuristic for getting a first.

How to actually choose modules

Here's the working framework we use when students ask us:

Step 1: Identify modules with high first-rate distributions. If you have access to data on how students performed in different modules historically, that's gold. Look for modules where 35%+ of students got firsts. Avoid modules where first-rate is consistently below 20%.

Step 2: Cross-check against assessment format. Modules assessed primarily by exam tend to have sharper grade distributions than modules assessed by coursework. Exams reward clear thinking; coursework rewards staying on top of deadlines. Know yourself.

Step 3: Look for breadth in cohort performance. Avoid modules where everyone gets a 2:1. Sounds counterintuitive, right? But compressed distributions (where everyone bunches in the 60s–65% range) are harder to break above. Look for modules with wide distributions where firsts are actually available and not competing for scarce space.

Step 4: Check that at least half your optional modules play to your strengths. You can't just pick data-heavy modules with high first-rates if you hate statistics. You'll burn out halfway through. The goal is high-ceiling modules in areas you actually care about.

Step 5: Don't frontload easy modules. The single biggest mistake students make: picking all the "easy" sounding modules and expecting to breeze through. The data shows that vague-sounding "overview" modules often have surprisingly compressed mark distributions. The cohort bunches. Save one technical-sounding, demanding module for each year — those tend to have wider distributions and more firsts available.

The final-year domino

If your university weights final year heavily (most do), here's the uncomfortable truth: your final-year module choice is more consequential than almost any other academic decision you'll make in three years.

A typical weighting: year 2 counts as 1/3 of your overall grade, year 3 counts as 2/3. That means your final-year modules are worth roughly twice as much as your year 2 modules.

If you averaged 68% in year 2 (high 2:1), you would need to average just 71% in year 3 to graduate with a first overall. If you averaged 60% in year 2 (low 2:1), you'd need 76% in year 3 — almost impossible if you're starting from a weaker year.

This is why module choice in year 3 is so critical. You don't need to be a genius; you need to be smart about which modules give you the ceiling to achieve a first if you perform at a decent level.

What separates people who get there

We've interviewed enough students who got firsts to spot the common threads. It's not intelligence. It's not hours worked. It's:

1. They knew the numbers. They understood their university's weighting, their current trajectory, and what average they needed in remaining modules.
2. They thought about module choice like data. Not "does this sound interesting?" but "who historically gets firsts in this module?"
3. They accepted the tradeoff. Getting a first often means taking at least one module that's harder or less appealing, because that module has a higher ceiling. They made peace with that.
4. They front-loaded their effort in year 2. If final year is heavily weighted, a strong year 2 gives you a cushion. A weak year 2 means year 3 becomes a tightrope.

FAQ

Is a first actually worth it?

That depends on your goals. For grad schemes in finance, law, and consulting, a first opens doors a 2:1 doesn't. For most other careers, a strong 2:1 is enough — employers care far more about internships and what you've actually built. But if you're aiming for postgraduate study or highly competitive entry, a first is the cleaner path.

Can I get a first if I'm starting from a low average?

Only if your university weights final year heavily enough. Crunch the numbers. If you're at 60% and final year is 70% of your grade, you'd need to average 80%+ in year 3 — doable but demanding. If final year is 50% of your grade, you'd need 90%+, which is essentially impossible. If year 1 counts, the math gets worse. Know your numbers.

What if I don't know which modules have high first-rates?

Ask your department. They usually have module feedback from previous cohorts. Or file a Freedom of Information request at your university asking for module-level grade distributions. It takes 20 days; you'll get data.

Should I pick hard modules or easy modules?

Pick modules with high first-rate distributions. Those usually correlate with being harder, but not always. Easier module ≠ easier first. Counterintuitive but consistent in the data.

Next steps

If you're in year 2, your final-year module choice is probably happening soon. Block out an hour. Get your university's regulations. Look at module-level data if you can. Talk to students who've already done year 3.

Then pick modules that give you a fighting chance — not modules that sound nice.

That's how you get a first.
