What To Study For The Asvab

The Armed Services Vocational Aptitude Battery (ASVAB) is a multiple-choice test, administered by the United States Military Entrance Processing Command, used to determine qualification for enlistment in the United States Armed Forces. It’s more than just a pass/fail exam; your ASVAB scores dictate which military jobs (Military Occupational Specialties - MOS) you qualify for. So, understanding what to study, and how to study effectively, is crucial for maximizing your opportunities in the military.

Understanding the ASVAB Structure

The ASVAB is comprised of nine sections, each designed to assess specific skills and knowledge:

1. General Science (GS): Measures knowledge of life science, earth and space science, and physical science.
2. Arithmetic Reasoning (AR): Assesses ability to solve basic arithmetic word problems.
3. Word Knowledge (WK): Tests the ability to understand the meaning of words through synonyms.
4. Paragraph Comprehension (PC): Evaluates the ability to understand written material.
5. Mathematics Knowledge (MK): Measures knowledge of mathematical concepts and applications.
6. Electronics Information (EI): Assesses knowledge of electrical circuits, devices, and systems.
7. Auto and Shop Information (AS): Measures knowledge of automotive maintenance and repair, and shop practices.
8. Mechanical Comprehension (MC): Evaluates understanding of mechanical principles, laws, and devices.
9. Assembling Objects (AO): Tests the ability to visualize how objects fit together.

The scores from these sections are used to create what's called the Armed Forces Qualification Test (AFQT) score, which determines basic eligibility for enlistment. The AFQT score is calculated using the following sections:

• Arithmetic Reasoning (AR)
• Word Knowledge (WK)
• Paragraph Comprehension (PC)
• Mathematics Knowledge (MK)

Your line scores are based on different combinations of subtests. Your line scores determine which jobs you qualify for.
