Free ASVAB practice test, one subtest at a time
The ASVAB has nine subtests on paper and ten on the computer version, and only four of them (Arithmetic Reasoning, Mathematics Knowledge, Word Knowledge and Paragraph Comprehension) set your AFQT score. Each of those four has a free practice page here with worked explanations.

Which ASVAB subtests can I practice here?
You can practice the four AFQT subtests below. The other five subtests have an explainer page with the official format and a study approach, but no practice questions, because AptiStep has not written reviewed items for them.

Where should I start?
Start with the free eight-question skill check. It samples all four AFQT subjects and points you to the lesson for your weakest one. Then use the subtest pages below to practice that subject. If you have only a few weeks, the two-week study plan sets the order.
For everything else about the test, see the guides on all subtests, the AFQT score, minimum scores by branch, line scores, CAT-ASVAB versus paper, PiCAT, retake rules and prep options.
Frequently asked questions
Is this a full ASVAB practice test?
No. It covers the four AFQT subjects with short original sets. A practice result here is not an AFQT percentile or a prediction of your real score.
Are these real ASVAB questions?
No. Real test questions are not published, and AptiStep does not claim to have them. Every item here was written for AptiStep.
Can I use a calculator?
No. The official page states: “You cannot use a calculator when taking the ASVAB.” (source, checked 2026-11-12). The math explanations here are done by hand.
