About ASVAB HQ: Free ASVAB Practice Tests and Guides

ASVAB HQ is an independent site. ASVAB HQ publishes free ASVAB (Armed Services Vocational Aptitude Battery) exam-prep resources: practice quizzes and plain-language study guides built from the official ASVAB subtest structure and AFQT scoring rules.

What this site is

The ASVAB isn't one test, it's ten subtests, and only four of them feed the AFQT score that determines whether you qualify to enlist at all. The other six set your line scores, which decide which military jobs you're eligible for. We built separate practice for each subtest and a plain explanation of how the AFQT composite gets calculated from Word Knowledge, Paragraph Comprehension, Arithmetic Reasoning, and Mathematics Knowledge.

How we work

Content here is drafted with AI assistance and then checked against the Department of Defense's published ASVAB technical manuals and current scoring tables before it goes live. That process is laid out in our editorial policy. Line score formulas differ by branch, and we keep each branch's version current rather than publishing one generic table.

How we make money

The site and its practice questions cost nothing. We earn affiliate commissions when readers buy study guides or prep courses through links on this site, and that's disclosed in full here.
