Army Cognitive Test Practice Questions

Below are fifteen worked practice questions — three from each of the five ACT sections — with the answer and the reasoning for every one. Work through each before reading the explanation.

Worked examples for all five sections

These follow the same format as the questions in our free trainer. Cover the answer, attempt the question, then check your reasoning against the explanation — that is far more useful than reading the answers straight through.

If a section here feels slow or uncertain, that is the one to spend your practice time on. For an explanation of what each section is measuring and why, see what the Army Cognitive Test is.

Error Detection

Count how many characters in the second string differ from the first. 0 means they are identical.

1
DS 14973
DB 14673
Show answer

Answer: 2 differences

Comparing character by character: S → B in position 2, and 9 → 6 in position 6. Everything else matches.

2
RT 6O9 3B
RT 609 38
Show answer

Answer: 2 differences

Both traps are letter-for-number substitutions: the letter O becomes a zero 0, and B becomes 8. These are the most commonly missed, because they look almost identical at speed.

3
QX 55170 9
QX 55170 9
Show answer

Answer: 0 differences

They are identical. Candidates lose marks here by assuming there must be a difference and talking themselves into one. If you reach the end and have found nothing, the answer is 0.

Number Fluency

Work out both calculations, then decide which produced the greater answer — or whether they are equal.

1
Step One: 12 − 2
Step Two: 14 − 6
Show answer

Answer: Step One

Step One gives 10, Step Two gives 8. Step One is greater.

2
Step One: 7 × 4
Step Two: 60 ÷ 2
Show answer

Answer: Step Two

Step One gives 28, Step Two gives 30. Close enough that estimating alone will not separate them — this is one you have to actually calculate.

3
Step One: 45 ÷ 5
Step Two: 3 × 3
Show answer

Answer: Same

Both give 9. "Same" is a real answer and appears regularly — do not assume one must be larger and pick at random.

Word Rules

Rule One gives three categories. Rule Two gives three words. How many words belong to the category in the same position?

1
Rule One: Tree · Clothes · Tree
Rule Two: Maple · Willow · Ash
Show answer

Answer: 2

Position 1: Maple is a tree ✓. Position 2 needs an item of clothing, but Willow is a tree ✗. Position 3: Ash is a tree ✓. Position is what matters — Willow being a perfectly good tree does not help when that slot asked for clothing.

2
Rule One: Metal · Animal · Metal
Rule Two: Copper · Badger · Zinc
Show answer

Answer: 3

Copper is a metal ✓, Badger is an animal ✓, Zinc is a metal ✓. All three positions match.

3
Rule One: Fruit · Colour · Fruit
Rule Two: Scarlet · Amber · Crimson
Show answer

Answer: 1

Only Amber matches, in position 2, as a colour ✓. Scarlet and Crimson are both colours but sit in positions asking for fruit ✗✗. A tempting set, because all three words are the right type — just in the wrong places.

Deductive Reasoning

Use the two ordering rules to build the full sequence, then answer the question.

1
Rule 1: Reference after Reservation
Rule 2: Confirmation after Reference
Question: What is first?
Show answer

Answer: Reservation

Rule 1 gives Reservation → Reference. Rule 2 adds Reference → Confirmation. Chained: Reservation → Reference → Confirmation. Nothing comes before Reservation, so it is first.

2
Rule 1: Briefing after Inspection
Rule 2: Inspection after Parade
Question: What is last?
Show answer

Answer: Briefing

The rules arrive out of order, which is the difficulty. Rule 2 gives Parade → Inspection; Rule 1 gives Inspection → Briefing. Chained: Parade → Inspection → Briefing.

3
Rule 1: Delta after Bravo
Rule 2: Bravo after Alpha
Question: What is second?
Show answer

Answer: Bravo

Alpha → Bravo → Delta. Bravo sits in the middle. Remember that "X after Y" means Y comes first — reading it the other way round is the single most common error in this section.

Orientation

Two rules describe a pair of arrows — one about colour, one about direction. Identify the pair that satisfies both.

1
Rule 1: Black ABOVE White
Rule 2: Up Left ABOVE Down Right
Show answer

Answer: Black ↖ on top, White ↘ beneath

Both rules point the same way: the top arrow must be black and pointing up-left, so the bottom one is white and pointing down-right.

2
Rule 1: White BELOW Black
Rule 2: Down Right BELOW Up Left
Show answer

Answer: Black ↖ on top, White ↘ beneath

This is the same answer as the previous question, written with BELOW instead of ABOVE. "White BELOW Black" and "Black ABOVE White" describe an identical pair. Flip any BELOW rule into an ABOVE rule before you look at the tiles.

3
Rule 1: White ABOVE Black
Rule 2: Up Right ABOVE Down Left
Show answer

Answer: White ↗ on top, Black ↙ beneath

Colour and direction are reversed from the first example. Settle which colour is on top first, then match the directions — trying to do both at once is what causes mistakes here.

How to practise so it actually helps

Doing questions slowly until you get them right builds the wrong habit. The ACT is timed, so accuracy without speed is not worth much.

A more effective progression is to build in stages: first understand the question type with no timer at all, then practise with a generous timer to build accuracy, then drill against a tight timer to build speed, and only then attempt full timed conditions.

That is exactly how our free trainer is structured — Learn, Practice, Drill, then Test — because moving straight to timed conditions tends to reinforce mistakes rather than fix them.

Free practice

You can practise five questions in every section free, with no account and no sign up. That is enough to see all five question types and find out which one you are weakest at.
