Buy now on Kaplan1. Official ASVAB sample questions: the best starting point
The Department of Defense publishes free sample questions for every subtest. Nothing shows the real question style better, especially for the picture-based subtests, Mechanical Comprehension and Assembling Objects. Use them first to find your weak areas, and again near test day to check progress. Less good: they’re samples, not full-length timed tests, and they don’t come with a study plan.
2. March2Success: the best free course
The Department of Defense says March2Success, an Army-developed basic skills program, has been approved by the Under Secretary of Defense for Personnel and Readiness. March2Success says it is free with no obligation to the Army, uses the same coursework Peterson’s sells to commercial customers, starts each unit with a pre-assessment that builds a custom learning path, and offers multiple practice tests. Best for people who want structure without paying. Less good: it covers basic skills broadly, so you may still want extra practice on technical subtests like Electronics Information or Auto and Shop.
3. The Army’s free app and pre-test
GoArmy says applicants can request a pre-ASVAB test or use the free U.S. Army ASVAB Challenge app to get familiar with the subjects. It’s an easy way to practice in short sessions. Less good: it’s a familiarization tool rather than a complete course, and it’s aimed at Army applicants.
4. Kaplan ASVAB Premium Prep 2026-2027: the best paid book
Kaplan’s retail listings describe ASVAB Premium Prep 2026-2027 as including 6 full-length practice tests in the book and online, more than 1,000 practice questions, and 500 flashcards printed in the book, with coverage of every section including Assembling Objects. List price is $39.99 at Barnes & Noble as of October 2026; Kaplan’s own ASVAB books page links to buy it. The listings also advertise a money-back promise, and Kaplan’s site says its guarantees carry conditions and restrictions, so read the terms before relying on it.
Best for people who want full-length timed practice in one place, especially if the free material leaves gaps. Less good: it costs money for practice that the free sources partly cover, and we haven’t verified that its question counts match the Department of Defense’s current figures. Our Kaplan ASVAB review goes into more detail.
Also consider: Kaplan ASVAB Total Prep 2026-2027
Kaplan’s fuller edition lists at $48.99 (BookPal list price, October 2026). The publisher says it has 7 full-length practice tests in the book and online, more than 2,000 practice questions with explanations, 500 online flashcards and the same money-back promise. It suits people who need a lot more practice than Premium Prep offers. Our Kaplan ASVAB review compares the two editions side by side.
How we ranked these
We ranked free official material first because it is the most accurate guide to the real test and costs nothing. After that, we compared options on what they add beyond the free material: full-length timed practice, coverage of all 10 subtests including Assembling Objects and the technical sections, explanations for answers, and price. Recruiters can’t recommend products, so we also looked for options that are easy to find without one: online, in bookstores or in public libraries.
We check each provider’s own pages and current retail listings, and every price we show links to where you can buy it. We don’t accept payment for placement and we don’t currently earn commissions from ASVAB providers. The full method, including what we don’t do, is on our how we rank ASVAB prep page.
How to choose
Take the official sample questions to see which subtests need the most work.
Use our minimum scores by branch and your target jobs' line scores to decide which subtests matter.
If you want structure, start March2Success. It costs nothing and covers the basics.
If you want full-length timed practice in one book, add Kaplan's Premium Prep, or borrow a current edition from a public library.
Ask your recruiter whether you'll take the computer or paper version, and what free practice they can arrange.
Quick checklist
- Start free with the official site and March 2 Success.
- Add Kaplan’s book if you want full-length timed practice.
- Focus on the four AFQT subtests first; they decide whether you can enlist.
- Ask your recruiter what practice they offer.
