Question 1 sur 17

Checking tests measure how accurately you compare information and notice small differences, usually against a time limit.
-
Question 2 sur 17
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.
-
Question 3 sur 17
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.
-

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.

Question 5 sur 17
Voir la réponse
Réponse: D. 40 seconds
20 minutes is 1,200 seconds, and 1,200 ÷ 30 = 40 seconds per question.
-
Question 6 sur 17
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.
-
Question 7 sur 17
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.
-
Question 8 sur 17
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.
-
Question 9 sur 17
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.
-
Question 10 sur 17
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.
-
Question 11 sur 17
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.
-
Question 12 sur 17
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.
-
Question 13 sur 17
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.
-
Question 14 sur 17
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.
-
Question 15 sur 17
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.
-
Question 16 sur 17
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.
-
Question 17 sur 17
Voir la réponse

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.
