How to Pass the Army Cognitive Test

There is no pass mark in the usual sense — the ACT produces a GTI score, and different roles require different scores. "Passing" really means scoring high enough for the trade you want.

Know the format before you sit down

The largest avoidable loss is time spent working out what a question is asking. If you have seen the format before, you start solving immediately instead of decoding.

Familiarity with all five sections is worth more than being excellent at any one of them.

Fix your weakest section, not your best one

Because the GTI reflects overall performance, your lowest sections hold your score down. Most candidates instinctively practise what they are already good at, because it feels better. It is the wrong strategy.

Work out which section you are slowest and least accurate at, and spend your preparation time there.

Answer everything

Leaving a question blank guarantees nothing from it. If you are running out of time on a question, make your best judgement and move on — dwelling on one item costs you the several that follow.

Practise against a clock

Untimed practice builds accuracy but not the ability to perform under pressure, and the ACT tests both. Introduce a timer early, and shorten it as you improve.

Tactics for each section

General advice only takes you so far, because each section fails in its own way. These are the specific points that cost candidates marks, section by section — the same guidance built into our trainer:

Error Detection

  • Work left to right, character by character. Reading the whole string and comparing an impression of it is what causes misses.
  • Watch for swapped digits (19 vs 91) and letter-for-number substitutions (O vs 0, B vs 8, I vs 1). These are the traps that are deliberately built in.
  • Never assume — check all the way to the end. Identical pairs do appear, and candidates talk themselves into finding a difference that is not there.

Number Fluency

  • Calculate both steps before moving on — you will not see the first one again once you advance.
  • If you are unsure, estimate. You are judging which result is greater, not reporting an exact figure, so being close is often enough.
  • Take extra care with division and multiplication, which can produce results far from what the numbers suggest at a glance.

Word Rules

  • Position is everything — a word must match the category in the same slot. A word that fits a category elsewhere in the rule scores nothing.
  • Say the rule to yourself before advancing. It disappears, and you are then working from memory.
  • If a word could belong to more than one category, only the position matters. Do not look for the best fit; look for the fit in that slot.

Deductive Reasoning

  • Build the chain step by step. Find the item that nothing comes after — that one is first.
  • "After" means later in the sequence. Read it carefully; the rules are often presented out of order deliberately.
  • "X after Y" means the order is Y → X. Reading this backwards is the single most common error in this section.

Orientation

  • ABOVE and BELOW are opposites describing the same thing — "A ABOVE B" and "B BELOW A" are an identical pair.
  • Settle which colour sits on top first, then match the directions. Doing both at once is what causes mistakes.
  • If a rule uses BELOW, flip it into an ABOVE before you look at the options — "Down BELOW Up" means Up is on top.

A two-week plan that works

If you have a fortnight before your test, this is a realistic structure. It matters less than doing something daily, but it stops you spending the whole two weeks on your favourite section.

Days 1–3 — learn the formats. Work through all five sections with no timer at all. The only goal is that no question type is unfamiliar. If you are still working out what a question is asking on test day, you have already lost time you cannot recover.

Days 4–7 — build accuracy. Practise with a generous timer. Aim to get questions right rather than fast. Track which section you are weakest at — most people are surprised, because the section that feels hardest is often not the one they actually score worst on.

Days 8–11 — attack the weakest section. Spend roughly two-thirds of your time on your worst section and the remainder keeping the others warm. This is the part almost everyone gets wrong, because practising what you are already good at is more enjoyable and feels productive.

Days 12–13 — full timed conditions. Sit complete timed tests across all five sections, back to back, to build the stamina of switching between question types under pressure.

Day 14 — stop. Light revision at most. Cramming the day before a processing-speed test costs you more in fatigue than it gains you in familiarity.

The mistakes that cost most marks

Practising only what you enjoy. Your GTI reflects overall processing, so your weakest section holds the score down. Time spent improving an already-strong section is close to wasted.

Working slowly to be certain. Accuracy without speed does not produce a good score, because the test measures both. If you are getting everything right and running out of time, you are being too careful.

Assuming there must be a difference. Particularly in Error Detection, identical pairs appear — and candidates invent a difference rather than answer zero.

Misreading the rule rather than the question. In Word Rules and Deductive Reasoning, most errors come from misreading the rule at the start, not from the items themselves. Two seconds re-reading the rule saves more than it costs.

Arriving tired. This is the one nobody counts as a mistake. Sleep affects processing speed directly, and the ACT measures processing speed.

On the day

Sleep matters more than last-minute practice — this is a processing-speed test and fatigue hits it hard. Arrive early, and treat the practice questions at the start as a warm-up rather than skipping through them.

You sit the ACT as part of your assessment, alongside the other elements of selection. Treat it as one component of a longer day rather than an isolated exam, and pace yourself accordingly.
