  • Complete a practical programming project based on the requirements of a real end user
  • Analyse and design a range of challenging problems before creating and testing solutions
  • Learn how a computer translates a computer program into a form that the CPU can understand
  • Find out about binary, hexadecimal and how to analyse and simplify Boolean logic
  • Understand what really happens in the ‘heart’ of a CPU
  • Be able to fully appreciate what happens when you click on a link to browse the Internet

80% exams, 20% course work. 
Two exam papers; Paper 1 (on-screen exam includes programming), Paper 2 (written exam).

Studying at Alton College:

Lesson activities will include writing a number of computer programs to solve a range of challenging problems, independently researching how devices and systems function, working on individual programming projects, actively participating in class discussion plus a number of quizzes to test understanding.

Entry requirements:

Students should normally have achieved at least five GCSEs at grade 9-4. For GCSEs which remain with the old grading system, a Grade 4 is equivalent to a Grade C.

You will need a logical mind to write your own computer program successfully and for this reason it is recommended that you have at least grade 5 in GCSE Mathematics.

Course costs:

None – online course textbook is available.
