20 questions in 15 minutes on computer applications, terminology, keyboard shortcuts, hardware, software, internet and basic security.
Computer Knowledge is 40 marks in every A&N Police written paper, at both Constable and Sub-Inspector level. It is also the easiest 40 marks in the paper: the syllabus is finite, it needs no aptitude, and a few evenings will carry most of it. Candidates who skip it are handing away a fifth of the paper.
General Instructions
- The clock is set at the server. The countdown timer at the top of the screen shows the time remaining. When it reaches zero the test ends by itself — you do not have to submit.

- You have not visited the question yet.
