Is this course for me?

Are you driven to figure out the answers to problems? Do you tend to take an analytical approach to solve problems? Computer Science is a practical subject where students can apply the academic principles learned in the classroom to real-world systems. It’s an intensely creative subject that combines invention and excitement, and can look at the natural world through a digital prism. Computer Science is an exciting and challenging field and it is constantly evolving.

Where can it take me?

Computing and computer technology are part of just about everything that touches our lives. From engineering to business management, medicine to biology, and language processing through to psychology, sociology and archaeology – all the sciences today need computer science in some form or another. This is exactly what makes the subject so exciting and is opening up ever more employment opportunities for computer scientists. Computer Science, therefore, is a forward-looking discipline that offers excellent prospects.
