Incredibly relevant and useful in a rapidly changing employment landscape, the course will require pupils to complete three assessments in the following areas:

Paper 1: Computer Systems.

  • The characteristics of contemporary processors, input, output and storage devices
  • Software and software development
  • Exchanging data
  • Data types, data structures and algorithms
  • Legal, moral, cultural and ethical issues

Paper 2: Algorithms and Programming.

  • Elements of computational thinking
  • Problem solving and programming
  • Algorithms to solve problems and standard algorithms

Non-Examination Assessment (NEA):
Produce their own programming project.

  • The learner will choose a computing problem to work through according to the guidance in the specification.
  • Analysis of the problem
  • Design of the solution
  • Developing the solution
  • Evaluation

The aims of this qualification are to enable learners to develop:

  •  An understanding and ability to apply the fundamental principles and concepts of computer science, including: abstraction, decomposition, logic, algorithms and data representation.
  • The ability to analyse problems in computational terms through practical experience of solving such problems, including writing programs to do so
  • The capacity to think creatively, innovatively, analytically, logically and critically
  • The capacity to see relationships between different aspects of computer science
  • Core mathematical skills.

CURRICULUM OVERVIEW

The course breaks down into the following areas:

  • Computer Systems: Learn how computers work, including hardware, software, and operating systems
  • Algorithms and Programming: Develop programming skills in Python, Java, or similar languages and explore how algorithms solve problems.
  • Data Representation: Understand how computers represent data in binary and use that knowledge to work with files, images, and sound.
  • Networking and Cybersecurity: Study how networks operate, how data is transmitted, and the principles of securing systems.
  • Problem-Solving & Software Development: Work on practical coding challenges and develop your own software applications.

Assessment of the course breaks down as follows:

  • Component 1: Computer Systems (40%): A written exam covering hardware, software, networking, and cybersecurity.
  • Component 2: Algorithms and Programming (40%): A written exam on algorithms, data structures, and programming concepts.
  • Component 3: Non-Exam Assessment (NEA) (20%): A practical project where you’ll design, develop, and test a software solution to a real-world problem. Exams are held at the end of the two-year course. The NEA is a project-based assessment that takes place during the second year.
