Set 5 of the Computer Awareness mixed quiz has 20 multiple-choice questions from 10 different topics of the subject: Memory and Storage, Keyboard Shortcuts and File Extensions, Software and Operating Systems and more. 10 of them were asked in real previous-year papers. A topic quiz checks one chapter; this set revises the whole subject at once, the way an exam paper does, where the next question can come from any chapter. Every question carries an explanation of why the correct option is right and why the others are wrong. Keep to the timer, read the explanations at the end, and go back to the notes of any topic where you slipped.
