The ASVAB answers two separate questions: whether you can enlist, and what you can do once you have. Almost everything written about it blurs the two. These guides keep them apart, and every number here comes from a Department of Defense source.

Two scores, two purposes. Four subtests produce the AFQT, a percentile from 1 to 99 that decides enlistment eligibility. All ten feed line scores, which decide job eligibility. A strong AFQT with a weak line score still closes the door on the job you wanted.
There are two operational versions and they are not the same test. The computer version is adaptive, shorter, and splits Auto and Shop Information into separate subtests. The paper version is fixed-form and combines them. Both report scores on the same scale, so a standard score means the same thing either way.

Every subtest is reported as a standard score with a mean of 50 and a standard deviation of 10. That is the number the scoring formulas use, and the number our calculators ask for — not the count of questions you answered correctly.
West Point, the Naval Academy, the Air Force Academy and ROTC scholarships all take an SAT or ACT score, not the ASVAB. Our SAT course covers Reading & Writing and Math in full, with adaptive practice tests and instant scoring.
The Armed Services Vocational Aptitude Battery is the test the United States military uses both to decide who may enlist and to decide what they may do. It has 10 subtests on the computer version and 9 on paper, and it is also given free in high schools as a career exploration tool.
There is no pass mark. Four of the subtests produce the AFQT, a percentile from 1 to 99, and each service sets its own minimum AFQT for enlistment — currently in the low 30s for high school diploma holders. The remaining subtests produce line scores that decide job eligibility, and those have their own separate cut scores.
The computer version at a Military Entrance Processing Station is 145 questions across 154 minutes of testing time. The paper version is longer in questions and slightly shorter in time: 225 questions in 149 minutes.
2 years from the date of testing, for enlistment purposes. That applies whether you took it at a military testing site or through your high school.
Yes. You must wait one calendar month after your first attempt, another calendar month after your first retest, and six calendar months after that.
Yes. There is no fee to take the ASVAB, whether you sit it through a recruiter or through the Career Exploration Program at your school. Free official practice is available too, which is one reason we publish guides and calculators here rather than selling a course.
