How the content is made

All lessons, questions, explanations and pictures are original material written for ASVAB Camp. They are not real ASVAB questions: the real test items are secure and are never published. Our questions are built to practise the same skills, so that the real test feels familiar.

Where the test facts come from

Facts about the test itself, such as the number of questions, time limits, how the AFQT is calculated, score categories, line scores and retest rules, come from official sources:

Official ASVAB website: test format, subtests, timing, scores and retest rules
DoD Instruction 1145.01: AFQT categories and enlistment standards
10 U.S.C. § 520: limits on enlistment by AFQT score and education
USMEPCOM Regulation 611-1: testing rules at the Military Entrance Processing Stations
ASVAB Career Exploration Program: the school version of the test

Some of these facts change over time. Each one that appears in a lesson is kept in a tracking list together with its official source, and the sources are checked every week. When a source changes, the lessons are corrected. The content was last updated on November 2, 2026.
