Academic Writing in the UK: Critical Writing & Essay Tips

You've spent hours working on your first university essay. You've checked the grammar, gone through your references and read it over more times than you'd like to admit.

Then your tutor's feedback comes back:

"Too descriptive."

"Needs more critical analysis."

It's frustrating when you've put so much work into an essay, only to get feedback that leaves you wondering what you actually need to improve.

At a UK university, academic writing isn't just about getting your grammar right or sounding formal. Your tutor wants to see that you've understood the question, put together a clear argument and used evidence to back up what you're saying.

If you're an international student getting used to a new academic system, these expectations might take some time to understand.

This guide explains what UK university tutors look for, the difference between descriptive and critical writing, and how to make your arguments more convincing.

There's also a free Academic Writing & Critical Analysis Worksheet further down the page, available as a PDF or editable Word document. It's there to help with tricky feedback and paragraph revisions.

1. What Is Academic Writing at a UK University?

Academic writing is about answering a question, making a clear argument and backing up your points with reliable evidence. Rather than just repeating what you've read, you need to explain what the evidence shows and why it matters to your argument.

You'll come across academic writing in essays, reports and dissertations, although the exact requirements depend on your subject and assignment.

When you first start writing essays at uni, you might think you need to use fancy words and long sentences to sound academic. But making your writing more complicated doesn't necessarily make it better.

Take this sentence:

Basic version:

Social media has a big impact on students.

There's nothing particularly wrong with the grammar, but big impact is vague. An impact on what? Concentration, study time or academic performance?

A more suitable academic version:

Social media use may affect students' concentration, although the impact depends on how and when it is used.

The second version is clearer because it focuses on concentration and makes it clear that the impact depends on how people use social media, rather than suggesting it affects everyone in the same way.

That doesn't mean it's necessarily true, though. If you're making a point in an essay, you'll still need evidence to back it up.

The University of Exeter's Writing Academically guide offers guidance on developing clear academic arguments, working with evidence and meeting academic writing expectations. Instead of chasing fancy vocabulary, focus on getting your point across clearly and explaining how you've reached your conclusion.

2. What Do UK University Tutors Actually Look For?

Sometimes, the problem with an essay isn't how much has been written, but whether it actually answers the question.

Answer the question, not just the topic

Imagine your essay question is:

To what extent does social media influence university students' academic performance?

If you spend paragraphs walking through the history of Instagram and TikTok, or just describing how students use these platforms, you’re on the right topic — but you’re not really answering the question.

The important words here are to what extent. Your tutor wants you to judge how much of an impact social media actually has.

You could explore cases where social media pulls students away from study, alongside cases where it helps them swap course materials. Then you draw on relevant research to weigh how powerful these effects really are.

For instance, some ways of using social media do go hand in hand with study interruptions. That does not mean every kind of social media use carries the same impact, though. You need evidence to back up that distinction. This is not the same job as just listing social media pros and cons.

Understand the instruction words in your assignment

University essay questions often include instruction words that show what the assignment is asking for. Understanding these before you start researching can save a lot of time.

For example:

Describe the effects of social media.

Compared with:

Critically evaluate the effects of social media.

Both questions are about the same topic, but they ask for different things. The first is about describing the effects, while the second involves weighing up the evidence, looking at how significant those effects are and deciding which conclusions are better supported.

The University of Sunderland's Academic Writing guide provides resources to help students understand academic writing tasks and organise their work.

Instruction words can mean slightly different things depending on the course, so it's worth having a look at the assignment brief and marking criteria first. If something doesn't make sense, check with your tutor. BIt is far better to clarify requirements early than to discover mid‑essay you have misunderstood the task.

3. Descriptive vs Critical Writing: What's the Difference?

This is one of the trickier areas for students getting used to university academic writing.

Descriptive writing simply tells your reader what happened, or what a source states.

Critical writing takes this a step further. It looks at what the evidence implies, how far we can rely on it, and how it connects back to your own argument.

What does critical writing actually look like?

Imagine you're discussing the relationship between social media use and students' study habits.

Descriptive version:

One study found a relationship between social media use and students' study habits.

This sentence reports a finding, but it doesn't explain what that finding means. If the rest of your paragraph simply summarises a second study and then a third, you could end up with a list of research findings rather than an argument.

A more critical version:

The study suggests a link between social media use and students' study habits, but this does not necessarily mean that social media use causes those habits to change.

The second version does more than just repeat the findings. It looks at what they actually tell us.

For one thing, just because social media use and study habits are linked doesn't mean one causes the other.

It's also worth thinking about what the study might have missed. The results depend on how the research was done, and other things like workload, time management or students' existing study habits could have had an influence too.

Note: These sentences are fictional writing examples, not quotations from an actual study. In assessed work, you would need to use and reference a real, verifiable source.

But critical analysis isn't just about knowing that correlation doesn't mean causation. It also means looking at how different studies compare, whether the research methods make sense and why some evidence might be more convincing than others.

Three questions to ask when writing critically

After writing a paragraph, ask yourself:

1. What does this evidence actually show?
2. Are there other possible explanations?
3. How does this support my argument?

For example, if a study links social media use to shorter study sessions, check what was measured and whether other factors could explain the result. That gives you more to discuss than the finding alone.

UCL's Writing Critically guide offers further guidance on analysing evidence, considering different perspectives and developing critical academic writing.

Being critical doesn't mean you have to pick holes in every study. If the evidence is convincing, it's fine to agree with the findings, as long as you can explain why.

4. How to Use Evidence to Support Your Argument

You might have plenty of references in your essay and still receive feedback such as “Needs more evidence” or “Develop your argument”.

Sometimes it's not about how many sources you've used, but whether you've made it clear how they back up your argument.

For example:

Social media can affect concentration. (Author, Year)

Even if you replaced that placeholder with a proper reference, the sentence wouldn't tell the reader what the research found or why it supports your argument. Adding a citation isn't the same as developing an argument.

Try Point → Evidence → Explanation → Link

One useful way to organise an academic paragraph is:

Point → Evidence → Explanation → Link

In other words, you introduce your point, provide evidence, explain what it means and connect it back to the essay question.

Imagine you're writing an essay about how social media affects students' academic performance. One point you could make is that constantly checking social media while studying might make it harder to concentrate.

Here's how that argument might look in a paragraph. This is a fictional teaching example: the study is hypothetical, not a source to use in assessed work.

Frequently checking social media while studying may make it harder to stay focused. For this example, imagine a study found that students who checked social media during a reading task took longer to finish it than those who didn't. This could suggest that social media interruptions affect how efficiently students complete academic work. However, it wouldn't necessarily prove that social media use leads to lower grades. More evidence would be needed to assess its wider impact on academic performance.

The paragraph follows four steps:

In an actual essay, the hypothetical finding would need to be replaced with a relevant, verifiable academic source. This approach is about making the reasoning clear, not adding references for the sake of it.

The University of Reading's Developing Your Essay Writing guide also explains how to develop paragraphs by making a point, introducing evidence, explaining its significance and linking it to the wider argument.

When checking your essay, have a look at what you've written after each reference. Is it clear why the evidence matters and how it backs up your point? If not, that's a good place to make some changes.

5. What Does Your Tutor's Feedback Actually Mean?

Tutor feedback at UK universities can be pretty brief. A comment like “Too descriptive” tells you something needs work, but doesn't really explain what to do about it.

Here are some common comments and what you can do about them.

These are just general guidelines, though. What the feedback actually means will depend on your assignment and its marking criteria.

For example, “Develop your argument” doesn't always mean adding loads more to your essay. Have a look at the paragraph your tutor commented on. Have you made a point and then moved on without really explaining it? Sometimes a sentence or two is all that's needed to make your reasoning clearer.

Ask yourself:

• Why does this evidence support my judgement?
• Have I skipped an important step in my reasoning?
• Is it clear how this paragraph answers the essay question?

If the feedback is still unclear, you can ask your tutor during office hours:

Could you explain what I need to do to make this paragraph more critical?

Instead of leaving it until your next assignment, try going back to a paragraph from your last essay and making a few changes based on your tutor's feedback. It's a good way to work out what needs improving.

6. Can AI Help You Improve Your Academic Writing?

AI is becoming a familiar part of uni life, from getting your head around tricky concepts to checking practice writing. For instance, a short practice paragraph can be useful for asking AI which parts are mostly descriptive and where more analysis might help. You could also ask:

Which points in this argument need more evidence?

The point is to spot gaps in your thinking, not to have AI write the answer for you.

Sovi's AI Notes can help organise course material and revisit unfamiliar concepts. For writing-related tasks, Smart Writing lets you enter a topic or instructions, choose an academic tone and generate content to review. Depending on your course rules, that may be useful for exploring ways to express an idea or organise a draft.

AI doesn't always get it right. Check any suggestions against your course materials and reliable sources, and make your own judgements about the argument and evidence. There's also a difference between using AI to learn and having it complete work you're expected to do independently.

The rules vary between universities, modules and individual assignments. UCL's guidance on generative AI in education and assessment is one example of why the specific assessment guidance matters. Check your assignment brief, and ask your tutor or module leader if you're unsure what's allowed or needs to be declared.

7. Frequently Asked Questions

What is academic writing in simple words?

Academic writing means answering an academic question with a clear argument and reliable evidence. It also means explaining what that evidence shows, rather than just repeating what you have read.

What's the difference between descriptive and critical writing?

Descriptive writing reports information or research findings. Critical writing examines what they mean and how well they support an argument.

Do I need perfect English for academic writing?

Clear, accurate English matters, but academic writing isn't just a grammar test. Your argument, evidence, analysis and ability to meet the assignment requirements can also be important parts of the assessment. Check your module's marking criteria for the specific expectations.

Can I use AI for academic writing at a UK university?

That depends on your university, module and assessment. Some uses of AI to support learning may be permitted, while particular assignments may restrict or prohibit certain uses. Always check the assignment brief, and declare AI use where your course requires it.

Final Thoughts

Academic writing at a UK university isn't just about using complicated vocabulary or adding lots of references.

What matters is whether you've answered the question, built a clear argument and explained how evidence supports your conclusions.

If you keep getting comments like “Too descriptive” or “Needs more critical analysis”, try revising one paragraph first. Check whether it simply summarises research or explains what the findings mean. It can be easier to see what needs changing when you focus on one section at a time.

If you're looking for extra support with your studies, explore Sovi's AI Notes for organising course material and Smart Writing for writing-related tasks.

Your argument and use of evidence should still reflect your own academic judgement and your university’s assessment rules.
