The Armed Services Vocational Aptitude Battery (ASVAB) is a multiple-choice test administered by the United States Military Entrance Processing Command. It is used to determine an individual's qualification for enlistment in the military. The test is divided into nine individual tests, each measuring a specific area of knowledge or skill. To prepare for the ASVAB, it's essential to understand the format, content, and scoring system. Here, we will provide a comprehensive overview and a sample practice test to help US Marines prepare for the ASVAB.
Understanding the ASVAB Test Format

The ASVAB test is comprised of nine individual tests, which are: General Science (GS), Arithmetic Reasoning (AR), Word Knowledge (WK), Paragraph Comprehension (PC), Mathematics Knowledge (MK), Electronics Information (EI), Auto and Shop Information (AS), Mechanical Comprehension (MC), and Assembling Objects (AO). Each test is designed to measure a specific area of knowledge or skill. The test is typically administered in a paper-and-pencil format, but it can also be taken on a computer.
ASVAB Test Content and Scoring System
The ASVAB test content is designed to assess a wide range of knowledge and skills. The test is scored based on the number of correct answers, with no penalty for incorrect answers. The scores are then used to determine an individual’s Armed Forces Qualification Test (AFQT) score, which is used to determine eligibility for enlistment. The AFQT score is calculated based on the results of four tests: Arithmetic Reasoning, Word Knowledge, Paragraph Comprehension, and Mathematics Knowledge.
Test | Description | Number of Questions | Time Limit |
---|---|---|---|
General Science (GS) | Tests knowledge of physical and biological sciences | 25 | 11 minutes |
Arithmetic Reasoning (AR) | Tests ability to solve mathematical problems | 30 | 36 minutes |
Word Knowledge (WK) | Tests ability to understand word meanings | 35 | 11 minutes |
Paragraph Comprehension (PC) | Tests ability to understand written passages | 15 | 13 minutes |
Mathematics Knowledge (MK) | Tests knowledge of mathematical concepts | 25 | 20 minutes |
Electronics Information (EI) | Tests knowledge of electronic principles | 20 | 9 minutes |
Auto and Shop Information (AS) | Tests knowledge of automotive and shop practices | 25 | 11 minutes |
Mechanical Comprehension (MC) | Tests knowledge of mechanical principles | 25 | 19 minutes |
Assembling Objects (AO) | Tests ability to assemble objects | 25 | 9 minutes |
