ASVAB Study Guide: Into ASVAB Sections

The ASVAB test is a combination of 9 subsections that are crafted to carefully measure a test taker’s academic prowess and technical aptitude. This ASVAB study guide will list all sections as follows and what they cover.

ASVAB Arithmetic Reasoning

Questions in the Arithmetic reasoning subtest relate to the process of solving math word problems – you know those questions you had in elementary, middle, and high school

You will need to take mathematical information (related to numbers, relationships, etc.) and create an arithmetic problem, and then solve it to find the right answer.

Whether you enjoy these types of problems or dread them, there is a process you can use to solve them quicker and easier. Your test administrator will provide you with scratch paper and two pencils for this portion of the ASVAB test. Calculators are not allowed. If you are taking the pencil-and-paper test, you will have 36 minutes to answer 30 questions and if you are taking the computer version, you will have 39 minutes to complete 16 questions.

ASVAB Assembling Objects

The Assembling Objects subtest of the ASVAB is designed to measure your knowledge of visualizing spatial relationships. In this section of the ASVAB, you will be required to view pieces of an object and then decide how those pieces fit together. If you’re asking yourself why this ability is important, the answer is that good spatial skills allow people to figure out maps and interpret graphs and technical drawings. For the Assembling Objects subtest, you will have 15 minutes to solve 16 problems on the CAT-ASVAB test and 16 minutes to finish 25 questions on the paper version of the ASVAB.

ASVAB Auto and Shop Information

The Auto and Shop Information subtest of the ASVAB question is about automobile systems and functions/malfunctions and questions involve common shop tools and fasteners and their uses. While your Auto and Shop Information subtest score is used to decide various job qualifications, it is not used in determining your Armed Forces Qualification Test score. On the ASVAB for the Auto and Shop Information subtest, you will have 7 minutes to answer 11 auto-related questions and 6 minutes to complete 11 shop-related questions. On the paper version of the ASVAB, you will have 11 minutes to finish 25 questions, which are usually split between auto-related questions and shop-related questions.

ASVAB Study Guide


How were you at math in high school? This subtest of the ASVAB is going to put you to the test. It is filled with questions covering basic high school math. Unfortunately, that means there is a lot for this test to cover, AND you’ll have to do a lot of jumping from one math concept to the next during the course of this subtest. One way to get ready for these rapid switches is to take our ASVAB practice test.

On the Mathematics Knowledge subtest, you will have 24 minutes to complete 25 questions on the paper version of the ASVAB. On the CAT-ASVAB you will have to answer 16 questions in 20 minutes. This subtest is counted as part of your Armed Forces Qualification Test score, so you will want to perform as well as possible. A good score on this subtest is also important to qualify for some military jobs.

ASVAB Paragraph Comprehension

Just as it sounds, in the Paragraph Comprehension subtest of the ASVAB you will be reading paragraphs and then demonstrating your comprehension of those paragraphs by answering questions. This test is a part of your Armed Forces Qualification Test score and is also used to determine qualifications for some military jobs.

In other words, this is a very important part of the ASVAB and you should do as well as you can on it. On the paper-and-pencil version of the real ASVAB, you will need to answer 15 questions in 13 minutes when you come to this section. If you take the CAT-ASVAB, you will need to COMPLETE 11 questions in 22 minutes in this particular section.

ASVAB Word Knowledge

The Word Knowledge subtest ON the ASVAB measures your vocabulary knowledge. It is one of the four subtests, along with paragraph comprehension, arithmetic reasoning, and mathematics knowledge, which are used to determine your Armed Forces Qualification Test score, which in turn determines your eligibility for military service. In addition, a good score on this section is required for a number of military jobs, everything from the obvious journalist position to the maybe not-so-obvious firefighter position.

In other words, this is an essential section of the ASVAB to do well and you should be sure to devote sufficient study time to preparing for this subtest. On the Word Knowledge subtest, you will have 8 minutes to get 16 questions done if you take the CAT-ASVAB. If you take the paper ASVAB, you will have 11 minutes to complete 35 questions. On this test, you will be required to distinguish words based on their spelling and to know what various words mean.

ASVAB Scores and AFQT Scores

The next part mentioned in this ASVAB Study Guide is about ASVAB Scores.

Free ASVAB Study Guide
Free ASVAB Study Guide

As mentioned above, there are 9 sections on the ASVAB that all calculate a different score, and these scores are used to determine which military jobs a candidate is qualified for your total score. However, four of them have been considered more important and make up the Armed Forces Qualifications Test (AFQT) score: Arithmetic Reasoning, Word Knowledge, Paragraph Comprehension, and Mathematics Knowledge. The other five areas in the ASVAB are General Science, Electronics Information, Auto and Shop Information, Mechanical Comprehension, and Assembling Objects.

Your scores in those 5 areas will decide how suitable you are for specific military occupational specialties and Enlistment Bonuses. A high score will help increase your chances of joining the specialty/job and signing the bonus you want. The U.S. Army also converts the ASVAB test scores into 10 other score areas (line scores) that determine what MOS you may qualify for:

  • Clerical (CL) – Paragraph Comprehension, Word Knowledge, Arithmetic Reasoning, and Mathematics Knowledge.
  • Combat (CO) – Paragraph Comprehension, Word Knowledge, Auto & Shop, and Mechanical Comprehension.
  • Electronics (EL) – Arithmetic Reasoning, General Science, Mathematics Knowledge, and Electronic Information.
  • Field Artillery (FA) – Mathematics Knowledge, Arithmetic Reasoning, and Mechanical Comprehension.
  • General Maintenance (GM) – Auto & Shop, General Science, Mathematics Knowledge, and Electronics Information.
  • General Technical (GT) – Paragraph Comprehension, Word Knowledge, and Arithmetic Reasoning (AR).
  • Mechanical Maintenance (MM) – Auto & Shop, Mechanical Comprehension, and Electronic Information.
  • Operators and Food (OF) – Word Knowledge, Paragraph Comprehension, Auto & Shop, and Mechanical Comprehension.
  • Surveillance and Communications (SC) – Word Knowledge, Paragraph Comprehension, Arithmetic Reasoning, Auto & Shop, and Mechanical Comprehension.
  • Skilled Technical (ST) – Word Knowledge, Paragraph Comprehension, General Science, Mechanical Comprehension, and Mathematics Knowledge.
