How to prepare

SyllabuzAI recommendation

Weight: 120 of 1000 marks (12%), and the third tie-breaker.
Pace in the exam: Shares a 20-minute part with English: 30 questions, about 40 seconds each.

Data representation and Boolean algebra are calculation-based. Practise conversions until they take under 30 seconds.
Hardware, software and internet topics are factual. Short daily revision works better than one long session.
Because the part is short, answer the questions you know first and leave lengthy conversions for the end.

Work through each unit in five steps: Learn the concepts → Solve practice questions → Take a timed chapter test → Review your mistakes → Revise.
