(subject to change)


  • Would you like to know how computers work and be able to take a look inside one and know what each of the different parts do?
  • Would you like to learn a computer language or develop your skills with programming in a fun way?
  • Would you like to have a subject that is relevant to the modern world of technology?


Computer science is the study of how computer systems work, how they are constructed and programmed. It is a mix of mathematics, science and engineering. There is an emphasis on programming and it is particularly suited to students who have a very good mathematical background and who can think clearly and logically.

With information technologies continuing to have growing importance there is huge demand for professionals qualified in this area. If you wish to go on to higher study and employment in the field of Computer Science, you will find this course provides a good stepping stone.

Post, or even pre-university, there are a variety of lucrative careers, in fact, the growth and evolution of technologies means in future there will be jobs that require computing skills we have not even thought about yet!
