Component 1: Principles of Computer Science

Written examination: 1 hour and 40 minutes

40% of the qualification 80 marks Content overview

This component will assess all topics:

  • Understanding of what algorithms are, what they are used for and how they work; ability to interpret, amend and create algorithms. Understand the requirements for writing program code
  • Understanding of binary representation, data representation, data storage and compression, encryption and databases
  • Understanding of components of computer systems; ability to construct truth tables, produce logic statements and read and interpret pseudo-code
  • Understanding of computer networks, the internet and the worldwide web
  • Awareness of emerging trends in computing technologies, the impact of computing on individuals, society and the environment, including ethical, legal and ownership issues
  • Assessment overview paper consists of multiple-choice, short open response, open response and extended open response answer questions

Component 2: Application of Computational Thinking

Written examination: 2 hours

40% of the qualification 80 marks

The main focus of this component will be:

  • Understanding of what algorithms are, what they are used for and how they work; ability to interpret, amend and create algorithms
  • Understanding how to develop program code and constructs, data types, structures, input/output, operators and subprograms
  • Understanding of binary representation, data representation, data storage and compression, encryption and databases

  • Understanding of computer networks, the internet and the worldwide web
  • Awareness of emerging trends in computing technologies, the impact of computing on individuals, society and the environment, including ethical, legal and ownership issues
  • Assessment overview paper is based on a scenario. It consists of short open response, open response and extended open-response answer questions. All questions are mandatory

Component 3: Project

Non-examined assessment: 20 hours

20% of the qualification 60 marks

Students will develop a computer program.

The content for this component will draw on:

  • Algorithms, decomposition and abstraction
  • Design, write, test and refine a program
  • Data. Assessment overview
  • The project will be set by Pearson
  • Project details will be released each September, from September 2017
  • Internally assessed and externally moderated
  • The assessment will be carried out at a computer under supervision
  • The assessment may take place over multiple sessions up to a combined duration of 20 hours
  • Students will produce a report on the development of their project
  • Students will produce a computer program
