Everything you need to understand the ASVAB, raise your AFQT score, and qualify for your target branch and MOS.
The Armed Forces Qualification Test (AFQT) score is derived from four ASVAB subtests and determines your basic eligibility to enlist. It is expressed as a percentile (1–99) — a score of 50 means you scored higher than 50% of the reference population (a 1997 study of 18–23 year-olds).
AFQT formula:
AFQT = AR + MK + VE
where VE = WK + PC

| Category | Score Range | Meaning |
|---|---|---|
| I | 93–99 | Top tier — all branches, all jobs |
| II | 65–92 | Excellent — qualifies for most jobs |
| IIIA | 50–64 | Above average — strong options |
| IIIB | 31–49 | Average — meets most branch minimums |
| IVA | 21–30 | Below average — limited eligibility |
| IVB | 16–20 | Below average — few options |
| IVC | 10–15 | Low — rarely accepted |
| V | 1–9 | Ineligible for all branches |
Word problems involving basic arithmetic: percentages, ratios, rates, and simple algebra. 16 questions in 36 minutes on the CAT-ASVAB.
Key Topics
Pro Tip
Draw a picture or write an equation for every word problem — never solve in your head.
Vocabulary in context. You are given a word and must choose its closest synonym, or identify meaning from a short sentence. 16 questions in 8 minutes.
Key Topics
Pro Tip
Learn 10 roots per day (port = carry, aud = hear, etc.) — roots unlock hundreds of unfamiliar words.
Short reading passages followed by questions testing main idea, detail recall, and inference. 11 questions in 22 minutes.
Key Topics
Pro Tip
Read the question before the passage so you know exactly what to look for.
High school math: algebra, geometry, and number theory. Solving equations, working with exponents, and coordinate geometry. 16 questions in 20 minutes.
Key Topics
Pro Tip
Memorize the area formulas for circle, triangle, rectangle, and trapezoid before test day.
Life science, earth science, and physical science. Broad coverage from biology and chemistry to weather and space. 16 questions in 8 minutes.
Key Topics
Pro Tip
Focus on human body systems — they appear on almost every test.
Electrical circuits, components, and principles. Ohm's law, series/parallel circuits, and basic electronics vocabulary. 16 questions in 8 minutes.
Key Topics
Pro Tip
Memorize the power triangle (P = V × I = I²R = V²/R) — it covers most circuit math.
Automotive systems and shop tools. Engine operation, drivetrain, and hand/power tool identification. 11 questions in 7 minutes.
Key Topics
Pro Tip
Know the four-stroke cycle (intake, compression, power, exhaust) cold.
Physical principles applied to machines: levers, pulleys, gears, and fluid systems. 16 questions in 20 minutes.
Key Topics
Pro Tip
For pulleys: count the ropes supporting the load — each one cuts the required force by half.
Not a standalone subtest — VE = WK + PC. This composite feeds directly into your AFQT score. Improving WK and PC is the fastest way to raise your AFQT.
Key Topics
Pro Tip
VE is the highest-leverage AFQT score to improve because it combines two subtests.
Spatial reasoning — given parts, choose which assembled image they form. Used only for certain Navy ratings. 16 questions in 16 minutes.
Key Topics
Pro Tip
Practice with physical puzzles or 3D rotation apps if spatial reasoning is a weak area.
Week 1–2
Baseline & Vocabulary
Take a full practice ASVAB. Identify your weakest subtest. Begin 10 WK roots per day.
Week 3–4
Math Mastery
Drill AR and MK daily. Focus on word problems, fractions, and algebra. Review geometry formulas.
Week 5
Line Score Subtests
Target the subtests for your desired MOS: GS, EI, AS, or MC. Use section-drill mode.
Week 6
Timed Simulations
Take 3 full timed simulations under test conditions. Review every wrong answer.
