Computing AS & A Level at Archbishop Tenison's School

Course description

Computing is at the leading edge of the changes within our society. It has changed both individual lives and community involvement around the world. Computing  is about finding solutions to real world problems. If you wish to gain an added understanding of digital technologies and programming then this is the course for you. 

Course content

The course is based around Python, the language used to code the Google search engine. The course focuses on understanding technology and its application to computing.

You will be in a supportive environment which fosters and encourages the development of skills, knowledge & understanding.

The two Year 12 AS modules consist of:

  • Unit 1: You will learn about computational thinking, how to program, binary representation, character coding, and how graphics and sound are represented inside a computer. You will also learn about the systems life cycle.
  • Unit 2: This focuses on machine level architecture, how instructions are processed by the computer, the structure of the Internet, website design and the wider consequences of computing. 

The A Level modules, studied in Year 13, comprise:

  • Unit 3: This covers advanced computational thinking and you will also investigate programming concepts and simulations. We also identify the role and classification of operating systems and databases and finally look at how we communicate and how networks are constructed.
  • Unit 4: This is a practical assignment which allows you to choose, design and build a project of your own choice. This is your chance to build a system which showcases your ability to innovate.

Entry requirements

In addition to the minimum entry requirements you will need a B grade at GCSE in Maths or Computer Science.


  • Unit 1: This is assessed through an on-screen examination (30% of the A level).
  • Unit 2: This is assessed through examination. (20% of the A level)
  • Unit 3: This module is assessed through examination (20% of the A level). 
  • Unit 4: This is a practical assignment

Future opportunities

Computing is aimed both at specialists who want to study computer science at degree level and also those who want to use computing skills in other areas of study or careers. As well as a huge range of opportunities in the IT industry as programmers, networkers or systems analysts, computing qualifications are useful in business and science careers across all sectors.
