The Armed Services Vocational Aptitude Battery (ASVAB) is a multiple choice test, administered by the United States Military Entrance Processing Command, used to determine qualification for enlistment in the United States Armed Forces. It is often offered to American high school students when they are in the 10th, 11th and 12th grade, though anyone eligible for enlistment may take it.[2]

The inverse of an exponent is the root which is indicated by a radical sign √.  A root consists of a radicand which is the number for which you’re finding the root and an index indicating which root you’re finding.  For example, in 3√8 the number 8 is the radicand and the number 3 is the root.  (A radical sign with no specified index is assumed to have an index of 2.)
The ASVAB test is administered to potential military recruits to help determine which branch of service and which military jobs they will be best suited for. It is not a test of intelligence and is administered only in English. The test consists of nine subjects: General Science, Arithmetic Reasoning, Word Knowledge, Paragraph Comprehension, Mathematics Knowledge, Electronics Information, Auto and Shop Information, Mechanical Comprehension, and Assembling Objects.
Mechanical Comprehension. Items contained within this section include topics that would typically be found in an introductory high school physics course and the application of these topics within a variety of situations. The questions in this portion of the test gauge examinees’ knowledge of principles related to gases and liquids, and their understanding of the ways in which these properties affect pressure, volume, and velocity. This subtest also includes questions that relate to the components and performance of mechanical devices.

Line Scores are used to determine if enlisted applicants are qualified to be trained in a specific military occupation. A type of line score, known as the General-Technical score, is used to determine if prospective officer candidates are qualified to join a specific branch of the military and be enrolled in officer training. Job selection for officer candidates is based on their performance in Officer Candidate School (OCS) and not on their General-Technical score.
The AFQT has been used in non-military settings as a proxy measure of intelligence, for example, in Herrnstein & Murray's book The Bell Curve. Because of the test's significance both inside and outside military settings, it is important to examine what the test measures, i.e. to evaluate the construct validity of the AFQT. Kaufman's 2010 review stated that David Marks (2010) scanned the literature for datasets containing test estimates for populations or groups taking both the AFQT and tests of literacy. One study on nine groups of soldiers differing in job and reading ability found a correlation of .96 between the AFQT and reading achievement (Sticht, Caylor, Kern, & Fox, 1972). Another study showed significant improvements among Black and Hispanic populations in their AFQT scores between 1980 and 1992 while Whites only showed a slight decrement (Kilburn, Hanser, & Klerman, 1998). Another study obtained reading scores for 17-year olds for those same ethnic groups and dates (Campbell et al., 2000) and found a correlation of .997 between reading scores and AFQT scores. This nearly perfect correlation was based on six pairs of data points from six independent population samples evaluated by two separate groups of investigators. According to Marks, "On the basis of the studies summarized here, there can be little doubt that the Armed Forces Qualifications Test is a measure of literacy." However, it is important to note that AFQT has been shown to correlate more highly with classic IQ tests than they do with one another, and that the "crystallized" intelligence measured by AFQT is measured very similarly by Wechsler, in particular.[8]

For almost a century, the U.S. military has been a pioneer in the field of using aptitude tests to evaluate an individual’s potential for service. The organization also uses the test to determine aptitude for various military occupational specialties (MOS). The use of aptitude tests began during World War I. While the group-administered Army Alpha test measured verbal and numerical ability as well as general knowledge, the Army Beta test was used to evaluate illiterate, unschooled and non-English speaking volunteers and draftees. The Army and Navy General Classifications Tests replaced the Alpha and Beta tests as a means to measure cognitive ability during World War II. The results of these tests, as well as additional classification exams, were used to assign recruits to a particular MOS.
It’s best to keep the contact information of your nearest recruiting office or your actual recruiter; they are your best bet for getting your scores. ASVAB scores are valid for up to two years before you need to retest so most offices will send your current scores via mail. If you can’t get yours by mail, you can pick them up from your local recruiting office.
The Armed Services Vocational Aptitude Battery (ASVAB) is a test that covers basic knowledge such as math and verbal skills, writing skills, and vocabulary. It is a required test for entrance into the military, but it can also be an indicator for general aptitude skills for other purposes. For those looking to go into military service, the ASVAB score is a crucial indicator of prospective job placement, so it is very important to take this test seriously and to focus on your strengths when taking the exam. Higher test scores often mean better jobs, higher salary, and more opportunities for advancement in the military.
According to the ASVAB testing site, the military has been using one form of test or another since World War I to evaluate potential soldiers and determine who was capable of service, in what jobs they should be placed, and which recruits might make good leaders. The ASVAB was developed in the early 1970s for use by all the military branches, although the Navy gives a variation of a subtest. Every person who enlists in the military takes the ASVAB. In addition, all high school students take the ASVAB, usually during their sophomore or junior years.
Air Force recruits must score at least 36 points the 99-point ASVAB. The overall ASVAB score is known as the AFQT score, or Armed Forces Qualification Test score. Exceptions may be made, however, for a handful of high school graduates who can score as low as 31. The vast majority, some 70 percent, of those accepted for an Air Force enlistment achieve a score of 50 or above.
The Auto and Shop Information subtest of the Armed Services Vocational Aptitude Battery involves questions about automobile systems and functions/malfunctions and questions about common shop tools and fasteners and their uses. Your Auto and Shop Information subtest score is used to determine various job qualifications. It is not used in determining your Armed Forces Qualification Test score. On the ASVAB for the Auto and Shop Information subtest you will have 7 minutes to answer 11 auto-related questions and 6 minutes to answer 11 shop-related questions. On the paper version of the ASVAB, you will have 11 minutes to answer 25 questions, which are usually split between auto-related questions and shop-related questions.

The questions that have a tendency to arise rather quickly are something along the lines of “why is this test so important?” and “What is the overall purpose of this test?” Well, first it is important to define the actual test and to assess the colorful history of the test. The Armed Services Vocational Aptitude Battery test (ASVAB) is a test that was officially formatted in 1968 with the intention of mentally preparing soldiers with knowledge that identifies with the following:
