Your recruiter in the army can tell you about possible services, but you will need to meet some basic requirements. The ASVAB online practice test offers professional training services and opportunities, but you must enter with a high school diploma. 

The test assesses your skills in the following areas:

• Knowledge of words

• Numeric operations

• Arithmetic thinking

• Extensive knowledge of words and understanding of paragraphs

• Encoding speed

• Automatically saves and stores information

• Electronic information

• Understand the paragraph

• Mathematical knowledge

• General science

• Mechanical understanding

To be useful in carrying out their duties, soldiers must be in good physical condition. You must be in good health, physically, and physically normal. You don't even need perfect eyesight to work in flight, but your vision problems will need to be addressed through lenses, contacts, or laser surgery.

Your ASVAB score determines your eligibility for the military as well as your eligibility for a specific career. Some jobs require a higher level of oral skills while others require math or technical skills. 

Soldiers depend on youth strength, but you must be 18 to join the service, although a parent or guardian can sign a consent form if you wish to join at 17. Active soldiers must be between 17 and 42 years old, reserves between 17 and 40, and guard soldiers between 17 and 35.

If you're pursuing a career path, be sure to check out the military job listings, then prepare to hone your performance in a specific area like you did for college entrance exams.
