Entry requirements for computer science degrees usually emphasize further mathematics, with some institutions asking for a background in physics. A background in psychology or sociology can provide an added dimension to your studies, as you would have gained an understanding of how humans process information, while other natural sciences may also be helpful. Undergraduate applicants for computer science degrees will not usually be expected to have formally studied computer science before university. However, it is recommended that you pick up a programming language, to gain an understanding of what is involved. While generally accepted beginner languages include Python and C++, Haskell, Java and Pascal are all languages you may come across during your studies. On the other hand, you may find some institutions discourage students from learning programming beforehand to avoid students learning ‘bad’ programming habits early on. Some institutions offer joint courses, in which computer science is studied alongside subjects such as mathematics, engineering and computing.
