How do you study for the ASVAB?
Study the four AFQT subtests first, because that score decides whether you can enlist: Word Knowledge, Paragraph Comprehension, Arithmetic Reasoning and Mathematics Knowledge. Take a practice test, drill the weakest of the four, then add the job subtests like Mechanical Comprehension. Most people plan three to six weeks. Minimum scores differ by branch, so ask a recruiter.

In more detail
The ASVAB has nine subtests, and they do two jobs. Four of them make up your AFQT score, which is the one that decides whether a branch will take you. The other five feed the line scores that qualify you for specific jobs. So study in that order: AFQT first, job subtests second.
The usual test is the CAT-ASVAB, taken on a computer. It adapts: if you answer correctly the next question gets harder, so you cannot skip around and you cannot go back. That makes steady accuracy more useful than speed. Math and vocabulary are the best places to gain points, because both improve fast with daily practice.

For math, practice word problems and basic algebra and geometry, and review the formulas a little every day.
- 5
For Word Knowledge, learn 10 to 15 new words a day with flashcards, and for Paragraph Comprehension, read short passages and state the main idea.
- 6
Add the subtests your job needs, such as Mechanical Comprehension, then take one timed full practice test in the last week.

More questions
How long should I study for the ASVAB?
Many people plan three to six weeks of regular practice. You may need less if you are close to your target score, and more if math or vocabulary is far behind.
What is a good ASVAB score?
It depends on your branch and the job you want. Each branch sets its own minimum AFQT score, and many jobs also need a minimum line score. A recruiter can tell you the numbers for your goal.
