Public Service Commission of Canada

The GCT-2A-324 is the Public Service Commission of Canada's abridged General Competency Test Level 2: 50 multiple-choice questions in 120 minutes, with a pass mark of 31 out of 50 to meet a university-education requirement for officer-level federal jobs. It tests number and letter series, numerical problems, and analytical reasoning. It replaced the 90-item GCT-2-314 on July 22, 2025, with no fee to candidates.

Sample GCT-2A-324 Practice Questions

Try these sample questions to test your GCT-2A-324 exam readiness. Each question includes a detailed explanation. Start the interactive quiz above for the full 100+ question experience with AI tutoring.

1Find the rule used to produce the series, then select the number that logically completes it: 2, 3, 6, 11, 18, 27, __

A.29

B.31

C.34

D.38

Explanation: The differences between consecutive terms are the consecutive odd numbers: +1, +3, +5, +7, +9. The next difference is +11, so 27 + 11 = 38. This is a second-level (quadratic) pattern, a common GCT-2A-324 series type.

2Select the number that logically completes the series: 4, 8, 16, 32, 64, __

A.96

B.128

C.120

D.112

Explanation: Each term is double the previous term (multiply by 2): 4, 8, 16, 32, 64, and 64 x 2 = 128. Recognizing a constant multiplier is the fastest way to solve geometric series.

3Select the letter that logically completes the series: A, C, E, G, I, __

A.J

B.K

C.L

D.M

Explanation: The letters advance by two positions each step (skip one letter): A(1), C(3), E(5), G(7), I(9), so the next is K(11). Converting letters to their alphabet positions makes the +2 rule clear.

4Select the number that logically completes the series: 1, 1, 2, 3, 5, 8, __

A.11

B.12

C.13

D.16

Explanation: This is the Fibonacci sequence: each term is the sum of the two preceding terms. 5 + 8 = 13. Watching for 'sum of the previous two terms' is a useful series-recognition strategy.

5Select the number that logically completes the series: 100, 50, 25, 12.5, __

A.6.25

B.6.5

C.5

D.8.25

Explanation: Each term is half the previous term (divide by 2): 100, 50, 25, 12.5, and 12.5 / 2 = 6.25. A constant ratio of one-half indicates a decreasing geometric series.

6Select the answer that logically completes the alternating series: 50A, 60C, 55E, 65G, 60I, 70K, 65M, 75__

A.L

B.N

C.O

D.P

Explanation: The letters follow A, C, E, G, I, K, M, advancing by two positions each time, so after M comes O. (The numbers run in a separate +10/-5 alternating pattern.) This is the official GCT-2A-324 sample item.

7Select the number that logically completes the series: 3, 7, 15, 31, 63, __

A.95

B.127

C.125

D.120

Explanation: Each term is double the previous term plus one: 3x2+1=7, 7x2+1=15, 15x2+1=31, 31x2+1=63, 63x2+1=127. Testing 'multiply then add a constant' resolves many irregular-looking series.

8Select the number that logically completes the series: 1, 4, 9, 16, 25, __

A.30

B.36

C.32

D.49

Explanation: These are the perfect squares: 1squared, 2squared, 3squared, 4squared, 5squared, so the next is 6squared = 36. Recognizing squares and cubes speeds up series identification.

9Select the letter that logically completes the series: B, D, G, K, P, __

A.U

B.V

C.T

D.W

Explanation: The gaps between letters grow by one each step: B to D is +2, D to G is +3, G to K is +4, K to P is +5, so P + 6 = V. Track increasing letter gaps for accelerating series.

10Select the number that logically completes the series: 2, 6, 12, 20, 30, __

A.40

B.42

C.36

D.44

Explanation: The differences increase by two each step: +4, +6, +8, +10, so the next difference is +12, giving 30 + 12 = 42. Each term also equals n(n+1): 1x2, 2x3, 3x4, 4x5, 5x6, 6x7 = 42.

About the GCT-2A-324 Exam

The General Competency Test: Level 2 Abridged (GCT-2A-324) is a standardized aptitude test from the Public Service Commission of Canada that assesses reasoning skills used to solve problems at the level required for officer-level federal positions. It is used as an alternative to a university-education requirement: passing it lets a candidate meet that requirement in eligible selection processes. The bilingual test contains 50 multiple-choice questions completed in 120 minutes on the Candidate Assessment Tool, spanning three question types — number and letter series, numerical problems, and analytical reasoning. As of July 22, 2025, the GCT-2A-324 replaced the 90-item GCT-2-314 as the alternative to a university-education requirement, and a calculator is permitted during the test.

GCT-2A-324 Study Tips from Top Performers

1Master series strategies: check first for a constant difference (arithmetic) or constant ratio (geometric), then test increasing gaps, alternating operations, squares, cubes, and Fibonacci-style sums.

2Convert letters to their alphabet positions (A=1, B=2, ...) so letter-series rules become as clear as number patterns.

3Drill mental percentages, ratios, rates, and fractions; even though a calculator is allowed, fast setup and estimation save time on 50 questions in 120 minutes.

4For analytical-reasoning passages, sketch a quick diagram or ordering chain and translate each clue into a constraint before answering.

5Use the contrapositive on if-then statements: if a rule says 'if A then B' and B is false, then A must be false.

6Budget your time, answer every question (there is no penalty for guessing), and eliminate the least likely options first when unsure.

7Practise on the official Candidate Assessment Tool sample test to get used to the on-screen calculator, font-size controls, and language switching before test day.

Frequently Asked Questions

What is the GCT-2A-324?

The GCT-2A-324 is the General Competency Test: Level 2 Abridged from the Public Service Commission of Canada. It is a 50-question, 120-minute multiple-choice test that measures reasoning skills for officer-level federal positions and is used as an alternative to a university-education requirement.

How many questions are on the GCT-2A-324 and how long is it?

The test has 50 multiple-choice questions and a time limit of 120 minutes. Plan to add roughly 20 to 30 minutes for administrative procedures on test day.

What is the pass mark?

The pass mark is 31 out of 50 to meet the alternative to a university-education requirement. You receive a pass/fail result along with your raw score.

What question types does it include?

There are three question types: number and letter series, numerical problems, and analytical reasoning. A calculator is permitted for the numerical questions.

How much does the GCT-2A-324 cost?

There is no fee to candidates. The Public Service Commission administers the test as part of the federal staffing process; you only cover any travel to the testing building.

Can I retake the test, and how soon?

Yes, but there is a 180-day waiting period before you can retake the GCT-2A-324, regardless of format. Retaking during the waiting period invalidates the result and resets the waiting period from the most recent test date.

Did the GCT-2A-324 replace an older test?

Yes. As of July 22, 2025, the GCT-2A-324 replaced the 90-item GCT-2-314 as the alternative to a university-education requirement. A score of 58 or above on the old GCT-2-314, or a pass on the GIT-310, remains valid for the same purpose.

Is the test bilingual and is it taken online?

The test is bilingual — you may take it in English or French and switch languages at any time. It is an online test supervised in person at a federal government building on the Candidate Assessment Tool; a paper version is available only in exceptional circumstances.
