Free Army SIFT practice tests, built to raise your flight-aptitude score
Practise all seven SIFT subtests — perception, spatial orientation, aviation knowledge, reading, math and mechanical — with realistic questions, instant scoring, and a full worked explanation after every single answer. No paywall, no card — the opposite of the apps that lock the good stuff behind a subscription.
Genuinely free — no paywall
Every subtest, every question and every worked explanation is free. No 10-questions-a-day trial, no card required. The paid apps lock the good stuff; we don't.
Verified answers, explained
Every question is written from scratch and independently checked — then you get a full worked explanation after each answer, so you learn the method, not just the result.
Built for the SIFT
All seven subtests are here — including bespoke Simple Drawings, Hidden Figures and Spatial Apperception engines you won't find in a generic quiz app — so you train the real test, not a lookalike.
Scored 20–80 — and 40 is the line
Your SIFT score runs from 20 to 80 with a mean of 50; 40 is the minimum to qualify and competitive applicants aim for 50+. You get only two lifetime attempts, with a 180-day wait between them — so it's worth going in prepared. Learn exactly how the test is built and scored.

Simple Drawings
The SIFT's opening speed test: five simple drawings, four the same and one different — tap the odd one out. About 100 items in 2 minutes, roughly 0.8 seconds each. Pure perceptual speed and accuracy, and wrong answers are penalised.
Hidden Figures
A classic embedded-figures test: five simple shapes labelled A–E, then busy line drawings. For each drawing, decide which shape is hidden inside it at the same size and orientation. 50 items in 5 minutes, with a guessing penalty.
Army Aviation Information
Aviation knowledge, weighted toward rotary-wing flight: helicopter aerodynamics, rotor components, flight controls, maneuvers and Army aircraft. It's the single subtest that rewards direct study, so points here are the easiest to earn.
Spatial Apperception
The aviator's orientation test. From a cockpit view of the horizon and coastline, pick the outside sketch showing the aircraft in that exact attitude — climbing or diving, banking left or right, and heading out to sea, in over land, or along the coast.
Reading Comprehension
Read a dense, factual passage and answer questions on what it states and reasonably implies. The traps are answers that are true in the real world but not supported by the text. 20 questions in 30 minutes — you have time to re-read.
Math Skills
Computer-adaptive math with no calculator: arithmetic, fractions, decimals, percentages, ratios, order of operations, basic algebra, geometry and word problems. Because it adapts, early accuracy sets the difficulty — and the value — of what comes next.
Mechanical Comprehension
Computer-adaptive mechanical reasoning: forces and equilibrium, work and energy, simple machines (levers, pulleys, gears, inclined planes), mechanical advantage, fluid pressure and practical formulas — with a SIFT lean toward the physics of flight. Often shown as a diagram to reason about.
Full-length practice
Learn the material, not just the answers
Plain-English study guides for every subtest — the formulas, rules and facts you actually need — plus a complete guide to the SIFT, how it's scored, the retake rule and how to study for each part.

SIFT questions, answered
What is the SIFT?
The SIFT (Selection Instrument for Flight Training) is the U.S. Army's aviation aptitude test. Anyone applying to fly Army helicopters — usually through Warrant Officer Flight Training (WOFT) — has to sit it. It has seven subtests covering perception speed, spatial orientation, aviation knowledge, reading, math and mechanical reasoning.
What is a passing SIFT score?
The SIFT is scored on a 20–80 scale with a mean of 50. The minimum qualifying score is 40, but flight-school selection is competitive, so strong applicants aim for 50 or higher.
How many times can I take the SIFT?
Twice in your lifetime. You can only retake it if you failed the first attempt, and you must wait 180 days between attempts. A passing score can't be retaken to improve it.
Is SIFT Ready really free?
Yes. Every subtest, the practice questions and the worked explanations are free.
How long is the SIFT and which parts are adaptive?
About 2.5–3 hours across the seven subtests, with a minimum of roughly 237 questions. Math Skills and Mechanical Comprehension are computer-adaptive — the difficulty adjusts to how you answer.
