ASVAB (Armed Services Vocational Aptitude Battery) Exam Guide

The AFQT — the enlistment-gate number — is computed from four subtests only: Arithmetic Reasoning, Mathematics Knowledge, Paragraph Comprehension, and Word Knowledge, reported as a 1-99 percentile and sorted into categories from I (93-99) down to V (1-9). The remaining subtests — General Science, Electronics Information, Auto and Shop Information, Mechanical Comprehension, and Assembling Objects — feed the composite line scores each branch uses for job qualification.

The practice bank here mirrors that structure: the AFQT math and verbal areas carry the most weight, the science and technical area covers the job-qualifying subtests, and a small strategy area drills the scoring and retest rules that shape enlistment timelines.

The ASVAB itself costs nothing to take — testing is arranged through a recruiter and administered by the Department of Defense at MEPS and MET sites. The real costs are time and opportunity: scheduling through a recruiter, travel to a testing station, and — if a retake becomes necessary — the retest clock of one month after the first attempt, another month after the second, and six months between all later attempts.

That clock is why preparation beats reattempting. A candidate who peaks on the first sitting keeps their enlistment timeline; one who needs a third attempt has added seven months. And a score jump of 20 or more AFQT points within six months triggers a mandatory confirmation test, so the system is built to reward genuine preparation over cramming spikes.

The CAT-ASVAB is adaptive: answer correctly and the next item gets harder, answer incorrectly and it gets easier, which pins down your ability with fewer questions — and means you cannot return to earlier answers. Scored-question counts and time limits per subtest (without tryout questions): General Science 15/12 minutes, Arithmetic Reasoning 15/55, Word Knowledge 15/9, Paragraph Comprehension 10/27, Mathematics Knowledge 15/31, Electronics Information 15/10, Auto Information 10/7, Shop Information 10/6, Mechanical Comprehension 15/22, Assembling Objects 15/18.

Unfinished questions are scored as random guesses — an explicit penalty — though the limits are liberal enough that nearly all examinees finish. The paper-and-pencil version, given at only a handful of MET sites, merges Auto and Shop into one AS subtest and drops Assembling Objects. Bring valid ID, arrive early, and expect your recruiter to wait outside the testing room.
