Mathematics is an important part of Computer Science. You will use mathematical methods to develop and understand algorithms and to describe the security of computer programs. Theoretical and practical programming is also a large part of the degree programme, and you will also learn about software architecture, algorithms, databases and designing user interfaces. The course programme at Computer Science is a combination of lectures and exercises. The lectures are held for large groups of students in auditoriums, while the exercises take place in classes of around 25 students.
