How to Get a First Class Degree

Written by the GradeCalc team · Last updated 18 May 2026 · 12 min read

A First Class Honours degree requires an overall average of 70% or above, but the path to getting there is less obvious than most students realise. This guide goes beyond generic study tips to explain what UK examiners actually look for in first-class work, how to use module and year weightings strategically, and what separates consistently high-performing students from those who fall just short.

The Mathematics You Need to Understand First

Before thinking about study habits, understand the numbers. A First requires a credit-weighted average of 70% across the years that count — typically Year 2 (weighted 33–40%) and Year 3 (weighted 60–67%). This has a practical implication that most students overlook: not every module needs to be above 70%. Your marks are averaged, and higher-credit modules have more influence on the average than lower-credit ones.

Consider a typical Year 3 where you have a 40-credit dissertation and four 20-credit modules. If your dissertation gets 78% and your four taught modules average 66%, your year average works out to about 70.4% — just enough for a First. Conversely, a student who scores a consistent 68% across everything will miss the threshold despite strong, coherent performance. Understanding this means you should direct disproportionate effort towards high-credit modules, and accept that getting 65% in a smaller module is fine as long as your weightier assessments compensate.

What First-Class Work Actually Looks Like

One reason students underperform is a fuzzy understanding of what 70%+ means in practice. It does not mean getting everything right. In most UK marking rubrics, marks in the 60–69% range indicate a solid, accurate response that demonstrates good understanding. Crossing into First-class territory requires something extra: original thinking, independent engagement with the subject, or analytical depth that goes beyond what was taught in the lecture.

In essay-based subjects, a 2:1 essay typically summarises and applies ideas taught in the course. A First-class essay does something with those ideas — it uses them to construct an original argument, identifies tensions between competing theories, or applies frameworks to contexts the lecturer never discussed. Markers often describe the difference as moving from "telling me what I told you" to "showing me you understand the subject."

In problem-based subjects like mathematics, engineering, or sciences, first-class marks come from demonstrating understanding of why methods work, not just how to apply them. Showing that you can adapt a technique to an unfamiliar problem, or explaining the limitations of an approach, signals the kind of deep understanding that 70%+ requires.

The practical implication is this: reading lecture notes closely is necessary but not sufficient. You need to engage with the wider literature, look at how academics in the field use and critique the concepts you are studying, and develop a view of your own.

Your Dissertation Is Your Best Opportunity

Most students underestimate how much their dissertation matters and overestimate how well they need to do elsewhere to compensate for a weak one. If your dissertation carries 40 credits and your taught modules average 20 credits each, a single percentage point on your dissertation is worth twice what a percentage point on a module is worth. Students who have a mediocre taught-module average of 67% but a strong 78% dissertation will often end up in First-class territory once the credit weighting is applied.

The dissertation is also the one piece of work where you have genuine control over topic, argument, and execution over many months. Unlike exams, where a single bad day can drag down your score, the dissertation rewards sustained, organised effort. Start your literature review before the summer before final year if you can. Work with your supervisor proactively — supervisors respond well to students who bring drafts early, ask specific questions, and act on feedback. The students who earn the highest dissertation marks are rarely the "most intelligent" in any absolute sense; they are the ones who treat the dissertation as a long project rather than a rushed final assessment.

Critical Analysis: What the Phrase Actually Means

The phrase "critical analysis" appears in virtually every UK marking rubric, but many students misunderstand what it requires. It does not mean being negative about sources, finding flaws for the sake of it, or stating that "there are arguments on both sides." Real critical analysis means evaluating evidence and arguments against explicit criteria — the quality of the data, the validity of the method, the scope of the claim, the context in which it applies.

In humanities, this might mean examining whether a historian's account is supported by primary sources, or whether a sociological theory developed in one national context translates to another. In sciences, it might mean discussing the sample size limitations of a study, noting whether a result has been replicated, or explaining why a standard model breaks down in particular conditions. What these have in common is that you are not just presenting information; you are reasoning about the value and limits of that information.

A reliable way to develop this habit is to ask, for every source you read: "Under what conditions would this be wrong?" If you can answer that question, you have understood the source deeply enough to write about it analytically.

Reading Strategically for First-Class Marks

The volume of reading matters less than what you do with it. Many students read extensively but passively — they absorb information without processing it. First-class students read with a purpose: to understand arguments, to find counterarguments, and to build a map of the intellectual territory around a topic.

Rather than reading everything on a reading list cover to cover, focus on understanding the key debates in each topic area. Ask your lecturer or check marking criteria to understand which thinkers or frameworks are considered foundational. Then read beyond the course by looking at recent journal articles and book chapters that engage with those frameworks. When you encounter disagreement between scholars, pay attention — those debates are often exactly what examiners want to see you engaging with.

Keep active notes as you read, not just summaries. Note your own reactions, questions, and observations. These informal notes often become the seeds of original arguments in essays and exams.

Getting to 70%+ in Exams

Exam performance at First-class level requires both solid content knowledge and exam technique. Many students lose marks not because they lack understanding but because they do not answer the question that was actually asked, or because they spend too much time describing when they should be analysing.

Practice with past papers under timed conditions at least three to four weeks before your exams. When you review your answers, focus on whether you addressed every part of the question, whether you made an argument or just listed points, and whether your evidence was well integrated. Ask for feedback on a practice answer from your lecturer or tutor if the opportunity exists — the gap between what students think they wrote and what markers see is often significant.

On mark schemes, understand that most UK university exam questions are worth marks for the quality of reasoning, not just the identification of correct facts. Showing how you reached a conclusion, and acknowledging the limits of your answer, will score better than stating conclusions with false confidence.

Managing the Full Year Consistently

Getting a First is rarely the result of exceptional performance in one assessment. It requires consistently strong performance across a whole year, which makes managing your time and workload throughout the year more important than heroic effort at the end. Students who spread their effort unevenly — coasting in the first term and cramming before exams — almost always underperform relative to their ability.

The most effective study pattern for First-class performance is reviewing and processing each week's material within a few days of the lecture, before the course moves on. This keeps knowledge fresh and makes exam revision a consolidation exercise rather than a first-time learning exercise. It also means you enter each new lecture with a proper understanding of prior material, which is essential for building the depth of understanding that earns 70%+ marks.

Allocate most of your independent study time to the modules that carry the most credits, particularly in final year. Spending equal time on a 20-credit optional module and a 40-credit core course is a strategic error that many students make.

Subject-Specific Considerations

The strategies above apply broadly, but the form they take varies significantly by subject. In quantitative disciplines (mathematics, physics, economics, engineering), depth of understanding is best demonstrated through problem-solving. The highest-scoring students can explain why methods work, apply techniques to novel problems, and make connections between topics — not just execute familiar procedures. In these subjects, working through problems without looking at solutions, and then carefully analysing where you went wrong, is one of the most effective ways to reach first-class competency.

In essay-based subjects (history, English, law, sociology, philosophy), the single biggest differentiator at first-class level is argumentative quality. The difference between a 65% and a 75% essay is usually not the quantity of knowledge displayed but the clarity, originality, and rigour of the argument. Students who outline their argument carefully before writing, and who structure each paragraph around a single analytical point, tend to write more persuasive essays than those who write discursively and hope the marker sees the argument emerging.

In lab or studio-based subjects (sciences, art and design, architecture), the quality of your methodology and your ability to reflect critically on your own process are what push marks above 70%. Demonstrating that you understood why you made particular design or methodological choices, and what those choices cost you, shows exactly the kind of self-aware, analytical thinking that first-class work requires.

If You Are Currently Below 70%

If your current average is in the 60–69% range, a First is still achievable in most cases, but it requires a clear-eyed assessment of why your marks are where they are. The most common reasons are: insufficient engagement with primary and secondary literature; essays that describe rather than argue; exam answers that are too broad and not analytical enough; and poor time management that leads to rushed work. Each of these is correctable.

Request feedback on every piece of assessed work, even if feedback is not provided automatically. Ask specifically: "What would I need to do differently to move this mark from 65% to 72%?" Lecturers who give that feedback are giving you the most valuable information you will receive at university. Students who act on it systematically are the ones who improve most quickly.

Frequently Asked Questions

Do I need 70% in every module to get a First?

No. You need an overall credit-weighted average of 70% or above. Some modules can be below 70% as long as others compensate. High-credit modules (like a 40-credit dissertation) have more influence on your average than low-credit ones.

Is getting a First realistic if I am currently averaging 65%?

Yes, it is realistic, depending on how many modules you have left and their credit values. A strong final-year performance, particularly a high dissertation mark, can shift an average significantly. Use our What Do I Need for a First? calculator to see what you would need on remaining assessments.

What is the most important module for getting a First?

In most programmes, the dissertation or major project carries the most credits in final year (often 30–60 credits), giving it a disproportionate influence on your final-year average. It is also the assessment where sustained effort over months is most likely to be rewarded. Treating the dissertation as a priority is usually the highest-return strategy.

How do I know what first-class work looks like in my subject?

Look at the marking rubric for each assessment — it will typically describe what distinguishes marks in the 70%+ band from the 60–69% band. Ask your lecturer what the highest-scoring students in previous years did differently. If you can get access to anonymised exemplars of first-class work, study them carefully.

Does Year 1 matter at all?

At most UK universities, Year 1 does not count towards your final classification, but it builds the foundational knowledge you need to perform well in Years 2 and 3. Students who disengage in Year 1 often struggle to reach first-class level later because the gaps in their understanding compound over time.
