Quiz thématique 1 : How attention-to-detail tests work

  1. Question 1 sur 17

    A test asks you to compare two columns and mark each pair as the same or different. What skill is it mainly measuring?
    Voir la réponse

    Réponse: B. Spotting small differences quickly and accurately

    Checking tests measure how accurately you compare information and notice small differences, usually against a time limit.

  2. Question 2 sur 17

    What is a transposition error?
    Voir la réponse

    Réponse: C. Two characters swap places, such as 5813 typed as 5831

    A transposition swaps two characters that sit next to each other. Here the 1 and the 3 changed places.

  3. Question 3 sur 17

    A record shows the code 40712. It was entered as 4072. What type of error is this?
    Voir la réponse

    Réponse: C. Omission

    One character (the 1) is missing, so this is an omission. The other digits are in the right order.

  4. Question 4 sur 17

    Which pair of characters is a classic look-alike pair that you should check with extra care?
    Voir la réponse

    Réponse: A. 0 (zero) and O (capital o)

    Zero and the capital letter O look almost the same in many fonts. Other common pairs are 1 and l, 5 and S, 8 and B, and rn and m.

  5. Question 5 sur 17

    A checking test has 30 questions and a 20-minute time limit. About how much time do you have per question on average?
    Voir la réponse

    Réponse: D. 40 seconds

    20 minutes is 1,200 seconds, and 1,200 ÷ 30 = 40 seconds per question.

  6. Question 6 sur 17

    You need to compare the account number 7302 9914 0586 with a copy. What is the most reliable method?
    Voir la réponse

    Réponse: C. Compare it in small groups, one group at a time

    Breaking a long number into small groups (chunking) lets you compare every character without losing your place.

  7. Question 7 sur 17

    The instructions say: "Mark A if the two entries are exactly the same and B if they are different." You see "Smith, J.R." and "Smith, J. R." What should you mark?
    Voir la réponse

    Réponse: C. B, because the spacing is different

    "Exactly the same" means every character, including spaces and punctuation. One entry has a space after "J." and the other does not.

  8. Question 8 sur 17

    What is a substitution error?
    Voir la réponse

    Réponse: D. One character is replaced by a different one, such as Brown typed as Browm

    In a substitution, the right number of characters is there, but one of them is wrong: the n became an m.

  9. Question 9 sur 17

    The source date is 2026-04-18. Which entry shows a duplication error?
    Voir la réponse

    Réponse: B. 2026-04-188

    A duplication repeats a character: the 8 was typed twice. The other entries show a transposition, an omission and a substitution.

  10. Question 10 sur 17

    You are unsure about a question and time is running short. What is the best approach?
    Voir la réponse

    Réponse: B. Choose your best answer, mark it for review if the test allows it, and move on

    Do not let one question use up your time. In the Public Service Commission's online tests, you can mark a question for review, and marking does not affect your score.

  11. Question 11 sur 17

    In the Public Service Commission of Canada's supervised online tests, what happens when the time allowed runs out?
    Voir la réponse

    Réponse: B. The computer closes the test

    The Public Service Commission says a timer shows the time left, and the computer closes the test after the allotted time.

  12. Question 12 sur 17

    A source sign says "Corner Store". The copy says "Comer Store". What most likely happened?
    Voir la réponse

    Réponse: A. The letters r and n were read as the letter m

    Next to each other, r and n can look like m. "Corner" has 6 letters and "Comer" has 5.

  13. Question 13 sur 17

    Two people check a list together: one reads the source aloud while the other follows the copy. What is the main benefit?
    Voir la réponse

    Réponse: C. Errors one person reads past are more likely to be caught

    A read-back check uses two sets of eyes and ears, so mistakes one person misses are more likely to be caught.

  14. Question 14 sur 17

    A unit is listed as "4B" in the source. The copy says "48". What kind of mistake is this most likely to be?
    Voir la réponse

    Réponse: B. A look-alike character mix-up between B and 8

    B and 8 look similar, especially in small print or handwriting. The number of characters is the same, so nothing was added or left out.

  15. Question 15 sur 17

    Two candidates each answered 30 questions. Ana got 27 right. Ben worked faster but got 22 right. The pass mark is 80%. Who passed?
    Voir la réponse

    Réponse: D. Ana only

    Ana scored 27 ÷ 30 = 90%. Ben scored 22 ÷ 30 = about 73%, below 80%. In checking tests, accuracy matters more than speed alone.

  16. Question 16 sur 17

    The source name is MARTINEZ. It was entered as MARITNEZ. What type of error is this?
    Voir la réponse

    Réponse: D. Transposition

    The T and the I swapped places (MAR-TI-NEZ became MAR-IT-NEZ). Both names have 8 letters.

  17. Question 17 sur 17

    The source shows the reference number 3317-0820. Which entry is a transposition of it?
    Voir la réponse

    Réponse: B. 3317-0280

    In 3317-0280, the 8 and the 2 have swapped places. The other options are an exact match, an omission and a duplication.

Questions fréquentes

What is the Certificate of Completion, and what is it not?

It shows that you finished this course and scored at least 80% on the final assessment. It is not an accredited qualification, an employer's test result, a test publisher's score or a government certification.

Are these questions from real employer tests?

No. Every question was written for this course to practise the same kinds of skills. Real tests differ between employers, so read your invitation and the instructions carefully.

How does the final assessment work?

It has 30 questions drawn at random from the course question bank, with a 30-minute time limit, so about 1 minute per question. You need 80% (24 of 30) to pass, and each attempt gives a new mix of questions.

What counts as "the same" in a comparison question?

Unless the instructions say otherwise, two entries are the same only if every character matches, including spaces, punctuation and capital letters.

How should I practise?

Read one lesson, take its untimed topic quiz and read the explanations for anything you got wrong. Do the practical exercises, then try the timed final assessment when you score well on all five topics.

L’attestation est-elle accréditée ou reconnue officiellement ?

Non. C’est une attestation de réussite privée, uniquement pour vos connaissances. Elle n’est reconnue, accréditée ni approuvée par aucun gouvernement, organisme de délivrance des permis, autorité de réglementation ou établissement d’enseignement, et elle ne remplace aucun permis, aucune certification ni aucune formation exigés par la loi.
