The ASVAB (Armed Services Vocational Aptitude Battery) is a timed test that anyone who is interested in enlisting has to take. The test helps not only you but recruiters determine what job would best suit you in the military.
The test consists of:
Mathematical questions
General Science
Word Knowledge
Mechanical Comprehension
Paragraph Comprehension
Auto & Shop Information
Electronic Information
Assembling objects
When people hear about the ASVAB they assume just because they take it automatically means they'll be enlisted, that is not true. The ASVAB is not a required but a recommended test in case college ends up not being for you. The ASVAB is a free career plan. When you take the ASVAB it's kept on file for two years.
If you're confused on what to do after high school, taking the ASVAB is a good second option. The ASVAB helps you discover your strengths, explore potential career paths and determines what you're eligibile for specific jobs not only for the military but in civlian workforces.
