The course

Want to work at the cutting-edge of computing technology and help in shaping the future of our global society? Computers, intelligent devices and the internet are central to so many aspects of 21st century life, from business and industry to governance and our personal lives. Their potential for transforming economies, driving efficiencies and enhancing the well-being of societies is almost limitless. Our progressive curriculum will give you the knowledge and technical skills that employers need, and introduce you to pioneering ideas and technologies to help you to realise your ambitions.

We cover all the essentials of application development, from programming to software engineering, databases to web development, computer graphics to robotics, and information security. You will also explore the fundamentals of computing – what computers do, and how efficiently they do it – and learn about a host of advanced technologies, from computer games, digital sound and music, to concurrent and parallel programming, machine learning, bioinformatics, the internet of things, computational finance and more. From the outset you will be experimenting with programming games, robots, Gadgeteer kits, Subversion, JUnit testing, Scrum-based Agile software and more, in our well-equipped laboratories.

We are a highly respected, research-focused department with a friendly approach and award-winning teaching. We offer a short-term summer work placement course and a dedicated personal adviser to guide you through your studies. You will also be welcome to join our thriving Computing Society. We are one of only seven departments in the UK to hold the Athena SWAN bronze award for increasing female participation in computer science. 

The course’s modular structure gives you the flexibility to tailor your degree to your interests. We also offer you the opportunity to follow a specialist pathway that matches your career ambitions. At the end of year 1 you will have the option of transferring onto one of these pathways (Artificial Intelligence, Information Security or Distributed & Networked Computing), as well as onto a year-in-industry course, or onto our longer and more advanced integrated masters course. Transferring onto our Software Engineering pathway requires previous programming experience and early permission to take the Software Development course in year 1, rather than Object-oriented Programming.

Our flexible degree programmes enable you to apply to take a Placement Year, which can be spent studying abroad, working or carrying out voluntary work. You can even do all three if you want to (minimum of three months each)! To recognise the importance of this additional skills development and university experience, your Placement Year will be formally recognised on your degree certificate and will contribute to your overall result. Please note conditions may apply if your degree already includes an integrated year out, please contact the Careers & Employability Service for more information. Find out more

We firmly believe that how we teach is at least as important as what we teach, and we know the importance of giving you the time and space to experiment and put theory into practice. We encourage you to use your creativity, both in project teams and independently, and to have fun while you learn. We use a variety of teaching methods, including lectures, small-group tutorials, supervised computer lab classes and problem-solving sessions. You will also be expected to complete guided independent study and group work. Our programming and software engineering teaching is very hands on, allowing you to learn at your own pace, whatever your previous level of experience. All students attend laboratory classes on games and robotics, giving you the chance to develop real applications with imagination and creativity..

We are proud of our award-winning teaching. Professor Dave Cohen won a College Excellence Teaching Prize for the re-design of our second-year software engineering courses, and he was shortlisted for a Times Higher Education Award for Most Innovative Teacher of the Year. The British Computer Society (BCS) has distinguished our software engineering teaching as an exemplar of 'best practice' in computer science education.

Assessment is through a mixture of examinations and coursework. Most course units have a two or three-hour written examination taken at the end of the year in which they are taught, but around half of your final award will come from assessed coursework, which could include project reports (including the full unit project in year 3), essays, oral presentations and software submissions.
