Begin with Discover Canada
IRCC bases the citizenship test on Discover Canada: The Rights and Responsibilities of Citizenship. The official guide is free in several formats. Work through it in short sessions and note unfamiliar topics.
Use the current test format
Current IRCC guidance specifies 20 multiple-choice or true-or-false questions, 45 minutes, and at least 15 correct answers to pass. The test is offered in English or French. Older sources may still say 30 minutes; follow your invitation and current official guidance.
Review ideas, not just answer positions
Alternate reading with recall. Explain a topic in your own words, answer a few questions, and revisit what you missed. Our sample questions are original, based on public facts, and are not reproduced from the guide or official test bank.
