Computer Science UCAS Personal Statement Examples UK (2025 Guide)
Writing a personal statement for UK university applications can feel overwhelming, especially if you’re applying for a course as competitive as computer science at a top institution like Oxford or Cambridge. With thousands of students competing for limited places, your personal statement needs to capture admissions tutors' attention immediately. In this comprehensive guide, we'll analyse personal statement examples, showing you exactly what separates outstanding statements from mediocre ones.
Understanding the UCAS Personal Statement Format
Before diving into our examples, it's crucial to understand the personal statement format UK universities expect. Your UCAS personal statement should be concise, engaging, and demonstrate genuine passion for your chosen subject. UK admissions tutors look for evidence of academic curiosity, relevant experiences, and clear motivation for pursuing your degree.
The New 2025 Three-Question Structure
Instead of a single 4,000-character essay, all university applicants from 2025 onwards must now answer three specific questions:
Why do you want to study this course or subject? - Your motivation and passion for pursuing chemistry
How have your qualifications and studies helped you to prepare for this course or subject? - Academic preparation and relevant coursework
What else have you done to prepare outside of education, and why are these experiences useful? - Research, volunteering, and extracurricular activities
You still have 4,000 characters total (including spaces), but must write a minimum of 350 characters for each question. You can distribute the remaining characters across the three sections based on your strongest experiences.
Personal Statement Examples: Computer Science
Let’s examine two contrasting approaches to writing about computer science experiences. These personal statement examples for university UK applications show the dramatic difference between unfocused writing and compelling storytelling.
Example Comparison: The Basic Website Project
Weak Example
“My passion for computer science was initiated by a chance programming assignment. In our computing class, we had the opportunity to practice creating a basic HTML website, which is a typical beginner project in programming textbooks, and web pages can be displayed with this technology.
During the project, I wondered why the CSS styling needed to be separated from the HTML content, but the development continued to be carried out according to the teacher’s guidance. After class I approached the teacher with my questions, and she told me that it was important for maintainability and organisation. Later, I learned that HTML and CSS separation is not only used for demonstration and exercises in computer science teaching, but also widely used in web development, mobile applications, software engineering and other fields. For example, CSS can be used to create responsive designs for different screen sizes; in mobile development, separation of concerns can be used to manage complex user interfaces. From the project and the further search for information about this field, I see the well-use of computer science in our daily life.”
What makes this a weak computer science personal statement?
Passive Language and Weak Opening: The phrase “My passion for computer science was initiated by” immediately signals weak writing. Passive voice makes the applicant seem disengaged from their own experience. The word “chance” suggests their interest was accidental rather than deliberate.
Excessive Technical Detail Without Purpose: The paragraph drowns in unnecessary technical explanations about HTML and CSS separation. UK admissions tutors assume you understand basic web development concepts; they want to see what you’ve learned about yourself, not textbook definitions.
Missing Personal Insight: While the applicant mentions asking questions, there’s no reflection on what this curiosity reveals about their problem-solving approach or computational thinking. The statement reads like a project report rather than a personal reflection.
Poor Structure and Flow: Ideas jump erratically from styling concerns to applications to daily life without logical progression. Each sentence feels disconnected from the last, showing no understanding of how programming concepts build systematically or interconnect.
Superficial Technical Understanding: Discussing basic HTML/CSS demonstrates only surface-level engagement with computer science, failing to show the algorithmic thinking, mathematical reasoning, or system design understanding that top universities seek in applicants.
Improved Example: Focused and Engaging
"Creating my first HTML website sparked deeper questions about web architecture. When our basic site struggled with mobile compatibility, I researched responsive design principles and discovered CSS Grid's mathematical approach to layout systems. I redesigned the site using flexbox algorithms and media queries, achieving seamless scaling across devices. This process revealed how web development intersects with mathematical problem-solving and user experience design."
Why this personal statement is an improvement:
Active Voice and Strong Opening: "Creating my first HTML website sparked deeper questions" immediately establishes agency and shows the applicant actively engages with challenges rather than passively following instructions.
Demonstrates Problem-Solving Progression: The logical flow from problem identification, to research, to implementation, and finally to insight. This shows genuine computational thinking and the ability to iterate and improve solutions.
Technical Sophistication: References to "CSS Grid's mathematical approach," "flexbox algorithms," and "media queries" demonstrate engagement with advanced concepts that go well beyond basic HTML/CSS, showing serious technical development.
Shows Independent Learning: "I researched responsive design principles" indicates initiative and academic maturity, exactly what universities want to see in students who can identify knowledge gaps and pursue solutions independently.
Connects Theory to Practice: The statement bridges mathematical concepts with practical application, showing understanding that computer science involves both abstract reasoning and real-world problem-solving.
Academic Insight: The conclusion about web development intersecting with "mathematical problem-solving and user experience design" demonstrates sophisticated understanding of computer science as a multidisciplinary field, not just coding.
Concise Yet Comprehensive: In four sentences, this covers problem identification, research, implementation, and academic reflection, showing efficient communication skills essential for computer science study.
Example Comparison: The Computer Science Hackathon
Weak Example
“In a hackathon competition organised by my school, I was looking forward to igniting the flame of coding passion in my heart through this battle of programming minds. The most memorable thing for me was the app development challenge. It required the design of a simple but functional mobile application to solve a real-world problem. From the selection of programming languages and the construction of the user interface to the precise implementation of features, every step was well thought out.
When I submitted my final application, I was filled with satisfaction and confidence that I had never felt before. Although I didn’t win the prize in the end, I was not disappointed because for me, the journey was greater than the destination. And I learned the importance of collaborative coding, and this hackathon made me more determined to love and pursue computer science. In the future, I would like to continue to devote myself to exploring the mysteries of programming for my university studies.”
Critical weaknesses in this personal statement:
Flowery, Meaningless Language: Phrases like “igniting the flame of coding passion in my heart” and “battle of programming minds” sound pretentious and add no value. UK admissions tutors prefer clear, direct communication about technical achievements.
Vague Descriptions: “Simple but functional mobile application” and “solve a real-world problem” could describe any hackathon project. Specific details about the problem addressed, technologies used, or algorithms implemented make statements memorable and credible.
Clichéd Reflections: “The journey was greater than the destination” is an overused phrase that suggests the applicant couldn’t find genuine technical insights to share about their coding experience or problem-solving process.
Weak Conclusion: The final sentence about “exploring the mysteries of programming” sounds generic and uncommitted. Strong computer science personal statements end with specific technical interests or academic goals related to algorithms, systems, or computational theory.
No Technical Substance: The statement fails to demonstrate any understanding of programming concepts, software architecture, or computational thinking that would distinguish a serious computer science applicant from someone with casual interest in technology.
Improved Example: Focused and Specific
“Competing in the National Student Hackathon, my team tackled food waste by developing a machine learning algorithm to predict grocery expiry dates from visual data. I implemented a convolutional neural network using TensorFlow, training it on 10,000 fruit images to achieve 87% accuracy in freshness classification. When our initial model struggled with lighting variations, I researched data augmentation techniques and applied image preprocessing to improve robustness.
Our app won third place, but more importantly, I discovered my fascination with computer vision and the mathematical elegance of backpropagation algorithms. This experience solidified my determination to pursue artificial intelligence research, particularly in applying deep learning to solve sustainability challenges.”
What makes this personal statement more effective?
Specific Technical Detail: Mentioning “convolutional neural network,” “TensorFlow,” and “backpropagation algorithms” demonstrates genuine engagement with advanced computer science concepts rather than surface-level programming knowledge.
Shows Applied Knowledge: The applicant doesn’t just describe what they built, but explains their problem-solving process—identifying the lighting variation issue and researching data augmentation shows computational thinking and debugging skills.
Quantifiable Results: “10,000 fruit images” and “87% accuracy” provide concrete evidence of technical achievement, while “third place” shows competitive validation without making winning the focus.
Forward-Looking Motivation: The conclusion connects past experience to specific future academic interests (AI research, sustainability applications), showing clear progression from hands-on experience to theoretical understanding and research ambitions.
Demonstrates Research Skills: “I researched data augmentation techniques” shows the ability to independently learn advanced concepts—exactly what universities want to see in computer science applicants who will need to keep pace with rapidly evolving technology.
