In complete honesty, one can say that the test identifies with an entire life's worth of knowledge. It essentially pulls from 3 different aspects. First, it draws from concrete facts that were acquired from all areas of a person's educational career. Secondly, it draws from a person’s ability to comprehend and use context clues to make assumptions. Lastly, it draws from a person’s physical/verbal skills to see if they can properly administer those more physical aspects. Overall this is why people have identified it as the “SAT on steroids.”
The four most important sections of the test—Word Knowledge, Paragraph Comprehension, Arithmetic Reasoning, and Mathematics Knowledge-make up your Armed Forces Qualifications Test (AFQT) score. Your AFQT score ranges from 0 to 100 and determines if you are able to enlist in the military and which jobs and programs you may qualify for when you are in.
The Armed Forces Vocational Aptitude Battery (ASVAB) is a test all enlisted candidates must take with the recruiter during the enlistment process. It is typically taken in the office on the computer in a shortened format. Then you will take the full ASVAB again at Military Entrance Processing Station (MEPS) on the day you swear into the Delayed Entry Program (DEP). The test is actually multiple subtests and graded with an overall percentile score – not percentage score. In other words, you are ranked accordingly with other recruits and by a percentage that you got correct.
The scores from the Word Knowledge, Arithmetic Reasoning, Mathematics Knowledge, and Paragraph Comprehension are combined together and known as the Armed Forces Qualification Test (AFQT). Your AFQT scores represent a percentile between 1 and 99 and measure your ranking compared to scores from other 18 to 23 year olds. If you score a 70 on your AFQT, this implies that you scored better than 70% of test takers. Your scores on the other six ASVAB tests will help identify which jobs may be appropriate for you in the military.
A military recruiter determines if the candidate is a possible recruit. A recruiter will ask about marital status, health, education, drug use, and arrest record. It is important for the candidate to be upfront and truthful when answering questions. Once the recruiter has determined the individual is qualified for additional processing, the ASVAB is scheduled. A physical examination may also be conducted at the time of the test. 
Cuatro de los resultados del ASVAB se combinan juntos para crear las fuerzas armadas que califican a la prueba, o AFQT, que tiene su puntuación. Las pruebas utilizadas para AFQT son conocimiento de las matemáticas, razonamiento aritmético, conocimiento de las palabras y la comprensión de lectura. En cuanto a los resultados del ASVAB individuales, resultado AFQT 50 indica que se ha anotado al menos tan bien como la mitad del promedio nacional. Una puntuación más alta significa que su puntaje es mejor que el porcentaje de personas.
The CAT-ASVAB is an adaptive test which means the test adapts to the ability of the test-taker. It is possible to administer a shorter test this way than with the pencil and paper test. When you complete a subsection of the test, you can then move onto the next section of the test without having to wait for an administrator. Subsections are still timed however and on average it takes about 1 ½ hours to complete the computer ASVAB.

Las naciones son unidades políticas y militares, pero no son necesariamente las unidades más importantes de la vida económica, ni son muy parecidas en un sentido económico. Lo que realmente tienen en común todas las naciones es el hecho político de su soberanía. Es más, la imposibilidad de los gobiernos nacionales de controlar las fuerzas económicas sugiere que las naciones son irrelevantes en la promoción del éxito económico.

Las Ciencias generales evalúan la capacidad de responder preguntas sobre una variedad de temas científicos que se enseñan en la mayoría de las escuelas secundarias. Los temas de biología abarcan botánica, zoología, anatomía y fisiología y ecología. Los temas de las ciencias de la tierra y el espacio están basados en astronomía, geología, meteorología y oceanografía. Los temas de las ciencias físicas miden la fuerza y la mecánica del movimiento, la energía, los líquidos, la estructura atómica y la química.
The AFQT score is the most important ASVAB score, because it determines if you can enlist in the U.S. Army. However, the U.S. Army also converts the ASVAB test scores into 10 other composite score areas known as "line scores" that determine what MOS an individual may qualify for. Listed below are the parts of the ASVAB that affect your AFQT test scores and each of the ten line scores.

The Armed Services Vocational Aptitude Battery is more commonly known as the ASVAB Test. If you are interested in a military career, you will need to pass this challenging test in order to qualify. It is used for all branches of the military which includes the Army, Navy, Air Force, Marines, National Guard, and Coast Guard. It is also used to gauge your abilities in specific areas that may be relevant to your job assignments within the military. For more information about the exact details of this exam, check out our article titled What is the ASVAB Test?
While you may want to get the ASVAB over with, it is important to give yourself enough time to prepare and practice for the ASVAB. Once you take the test you will have to wait 30 days before you are eligible to re-take the test if you got a non-passing score, or if you want a better grade. After you retake the test twice, you will need to wait for a 6 month time period before being able to take the test again. For this reason, it is important to pick an ASVAB test date that gives you plenty of time to practice and prepare for each section of the test.
Focusing Your Study - As you take more and more sample tests you begin to get a feel for the topics that you know well and the areas that you are weak on.  Many students waste a lot of valuable study time by reviewing material that they are good at (often because it is easier or makes them feel better).  The most effective way to study is to concentrate on the areas that you need help on.
After adding so much information to the aptitude test, there was a bit of difficulty interpreting the test results. In addition to that, a vast majority of test takers were deemed as being under qualified based on their test results. This is why the percentile change was made. It ensured that a 50% actually correlated with a person doing better than 50% of the test takers. Those revisions have worked hand-in-hand with the preparation of the armed forces.
