Computer Science

AQA AS Level Computer Science

This is designed to allow students to demonstrate knowledge of the fundamental principles of the subject whilst developing problem solving abilities in a computing context, using an algorithmic approach. Students will gain opportunities to demonstrate knowledge of programming, through a problem solving scenario and to develop an understanding of the hardware and software of a computer.

How will I be assessed?

The course includes practical and written assessments. A range of assessment methods will be used throughout the course by your teacher to provide you with constant feedback and support.

Paper 1

This paper tests a student’s ability to program, as well as their theoretical knowledge of computer science from subject content points 10 – 13 from the above list.

On-screen exam: 2 hours 30 minutes

40% of A-level

Paper 2

This paper tests a student’s ability to answer questions from subject content points 14 – 21 from above list.

Written exam: 2 hours 30 minutes

40% of A-level

Non-examined assessment

The non-exam assessment assesses student’s ability to use the knowledge and skills gained through the course to solve or investigate a practical problem. Students will be expected to follow a systematic approach to problem solving.
