COMPUTER SCIENCE (OCR)

A Level Course Outline

What is A Level Computer Science?

Computer Science encompasses the theoretical aspects of how a computer is designed, used and applied to solve real world problems. It is an applied subject that provides students with practical problem solving skills in a variety of programming language. It provides a strong foundation for students who wish to enter a career in Computer Science as Programmers, Data Analysts, Cyber Security Consultants, Web Designers, Games Developers or AI engineers. It is aimed at students who see themselves as developing their own computer software and hardware.

What Skills Will Students Develop When Studying Computer Science?

Computer Science students will develop the ability to:-

• Use technical language appropriately;
• Apply skills in logic to solve problems; and
• Increase their awareness of existing and emerging technologies and the impact they have on society, organisations and individuals.

What Will Students Encounter in A-level Computer Science?

There is a substantial coursework element in the second year of the Computer Science course which requires students to create a complete piece of bespoke software to solve a real-life problem. The project is divided into five stages: Analysis, Design, Implementation, Testing and Evaluation. Students must be able to plan their time effectively throughout the course in order to meet the project deadlines. Consequently, the Computer Science course is only suited to students who can work consistently and independently, week by week.

The theoretical components include more advanced knowledge, understanding and application of data handling, file handling, computer architecture and number representation. A command of more sophisticated terminology is expected, along with more advanced programming techniques including recursion, object-oriented programming and more complex algorithms.

Structure of the Course

This course will be taught for 6 x 1-hour lessons per week. Homework will be set weekly and deadlines must be adhered to. Reading of textbooks is essential.
