The ASVAB is a multiple-choice test that evaluates strengths in ten areas: general science, word knowledge, arithmetic reasoning, numerical operations, paragraph comprehension, auto and shop information, coding speed, mechanical comprehension, electronics and mathematical knowledge. There are 200 items on the test, and it takes approximately 180 minutes to complete.
The four most important areas you will be scored in are: word knowledge, arithmetic reasoning, paragraph comprehension and mathematical knowledge. These scores determine if you qualify to enlist in the armed services and if you are eligible for specialty jobs and a signing bonus.
The first version is CAT (computerized adaptive testing), in which a correct answer leads to more difficult questions. The MET-site test is given only for entrance into the military, while the Student ASVAB allows students to explore career opportunities.
According to Army.com, the key to doing well on the ASVAB is to obtain a practice test and study guide. Review all subjects that will be covered on the test. The practice test should be taken as if it were a real test, and it should be completed within the specified time.
When taking the ASVAB, answer all questions. When you don't know the answer, take an educated guess. If you can't wager an educated guess, a blind guess will do.
