Computer Science IB SL & HL Level 3 Group 4 at Tonbridge Grammar School

Course description

Computer Science requires an understanding of the fundamental concepts of computational thinking as well as knowledge of how computers and other digital devices operate. The course is engaging, accessible, inspiring and rigorous. Drawing on a wide spectrum of knowledge it enables and empowers innovation, exploration and the acquisition of further knowledge. Computer Science interacts with and influences cultures, society and how individuals and societies behave; raising ethical issues. To study Computer Science you need confidence in mathematics, to enjoy problem solving and be curious about how technology works.  

Course content

There are four core topics: system fundamentals, computer organization, networks and computational thinking, problem-solving and programming.

The higher level extension incudes some practical elements and covers abstract data structures, resource management and control. There is also an annually issued case study. The major practical work undertaken is a solution that students develop to demonstrate the application of skills using object-oriented programming.

Students get the opportunity to undertake work experience directly related to computer science at various companies from specialist software developers to software engineering departments of global organisations.

This subject will enable access to further study and careers in the high demand business sectors of Computer Science, Artificial Intelligence, Software Engineering, Computer Games, Films, Finance; virtually all areas of business and society. 

Entry requirements

All candidates should have GCSE Grade 6 or above (or its equivalent) in English, Mathematics, at least one Science and one language where studied. Where equivalence cannot be established the School will set appropriate I/GCSE papers to confirm that the applicant is capable of satisfying the academic profile required for the subjects to be studied and the IB Diploma Programme as a whole.


Assessment is by written examinations that cover the core topics and a Higher Level extension. The practical programming solution is marked by the subject teachers. 

Future opportunities

Last year half of our Higher Level students went on to study Computer Science at Cambridge, Warwick, Birmingham and Bath universities.
