In more detail
Which version you take decides the count. Most applicants take the CAT-ASVAB on a computer at a Military Entrance Processing Station (MEPS). It is adaptive: each answer sets the difficulty of the next question, so it needs fewer questions to measure you. The paper version gives everyone the same set, so it needs more questions per subtest.
On the computer test you cannot go back to change an answer once you have submitted it. The official ASVAB table lists 135 scored questions. Any tryout questions you see in 2 to 4 subtests do not count toward your score.
Only four subtests make up your AFQT score, the number that decides whether you can enlist: Arithmetic Reasoning, Mathematics Knowledge, Word Knowledge and Paragraph Comprehension. On the computer version that is 55 scored questions. The other subtests feed the line scores used to qualify you for specific jobs.

Step by step
- 1
Ask your recruiter which version you will take and which AFQT score and line scores your target jobs need.
- 2
Take one timed practice test to see where you stand on the four AFQT subtests.
- 3
Practice your pacing per subtest. Paragraph Comprehension gives you 27 minutes for 10 questions, but Word Knowledge only 9 minutes for 15, so vocabulary has to be fast recall.
- 4
Work math word problems by hand every day. Calculators are not allowed on the ASVAB.
- 5
On the computer test, keep reading and answering properly when time runs short. The CAT-ASVAB penalizes unfinished subtests, and a run of random guesses at the end can cost you more. On the paper test, blanks count as wrong, so guess.
- 6
Take a full timed practice test in the last week to check your pacing.
