Your success on ASVAB test day depends not only on how many hours you put into preparing, but also on whether you prepared the right way. It’s good to check along the way to see whether your studying is paying off. One of the most effective ways to do this is by taking ASVAB practice tests to evaluate your progress. Practice tests are useful because they show exactly where you need to improve. Every time you take a ASVAB practice test, pay special attention to these three groups of questions:
Figure 2.7 shows FY 1977 as the low point and FY 1992 as the high point in accessing recruits in Categories I to IIIA. In FY 1977, 34 percent of accessions scored in the top half of the AFQT distribution. Only 13 percent of Blacks, 19 percent of Hispanics, and 20 percent of "Others" scored in Categories I–IIIA. [3] Fifteen years later, in FY 1992, the majority of minority accessions achieved scores in the I–IIIA range (Blacks - 56 percent, Hispanics - 67 percent, "Others" - 67 percent). Hispanics have shown the most marked increase, with a 48-percentage-point gain in Category I to IIIA accessions from FY 1977 to FY 1992.

A lot of people see the “CAT” term attached to the ASVAB test when they first start looking into the test and aren’t sure what that stands for. This term is an acronym and it stands for “Computerized Adaptive Test”. There are three different versions of the ASVAB test. The CAT is available at military processing stations for enlisting soldiers. The pencil and paper (also known as the P&P or S-ASVAB) version of the test is available for high school and college students who may not actually enlist. The third type of ASVAB test is the MET-ASVAB, or Mobile Examination Test, which is available only for enlisted soldiers at mobile testing centers (this test is also done with paper and pencil).
Military history has a number of facets. One main facet is to learn from past accomplishments and mistakes, so as to more effectively wage war in the future. Another is to create a sense of military tradition, which is used to create cohesive military forces. Still, another may be to learn to prevent wars more effectively. Human knowledge about the military is largely based on both recorded and oral history of military conflicts (war), their participating armies and navies and, more recently, air forces.
When you are considered a career in the military you need to take the ASVAB test. But each branch of the military has different ASVAB requirements that you need to meet. They are different levels of education that you must reach to take the test. But you also need to score a certain amount of points on that ASVAB test to gain access into the branch you desire.

AFQT scores are reported as percentiles between 1-99. An AFQT percentile score indicates the percentage of examinees in a reference group that scored at or below that particular score. For current AFQT scores, the reference group is a sample of 18 to 23 year old youth who took the ASVAB as part of a national study conducted in 1997. Thus, an AFQT score of 95 indicates that the examinee scored as well as or better than 95% of the nationally-representative sample of 18 to 23 year olds. An AFQT score of 60 indicates that the examinee scored as well as or better than 60% of the nationally-representative sample.

The Electronics Information section of the practice test gauges your knowledge of electrical equipment and parts, including circuits, currents, batteries, and resistors. An example may be, “Because solid state diodes have no filament, they: don’t work, are less efficient than tubes, require less operating power, or require more operating power?” The CAT-ASVAB has 16 questions in 8 minutes; the paper-and-pencil version has 20 questions in 9 minutes.
Auto and Shop Information tests aptitude for automotive maintenance and repair, and wood and metal shop practices. The test covers several areas commonly included in most high school auto and shop courses, such as automotive components, automotive systems, automotive tools, troubleshooting and repair, shop tools, building materials, and building and construction procedures.
One ASVAB sub-measure, the Armed Forces Qualification Test (AFQT)--which is just a separate analysis of the same tests that focuses only on four of the subtests--is also population-referenced, but its score from 1-99 is a percentile score. This means that if you score a 73, you scored as well as or higher than 73% of test-takers in the national sample.
