The Air Force has four component zones comprising individual ASVAB subtests known as MAGEs. All Air Force line results are percentage estimates in the 0-99 range. The four component areas of ASVAB online practice tests with points that make up (MAGE) are:
M = Mechanical Skills Assessment – Determined by General Science (GS), Mechanical Understanding (MC) and Auto/Workshop (USA).
A = Assessment of administrative skills – verbal expression (VE).
G = General skill assessment – determined by arithmetic reasoning (AR) and verbal expression (VE).
E = Electronic Ability Assessment – Determined by General Science (GS), Arithmetic Reasoning (AR), Mathematical Knowledge (MK) and Electronic Information (EI).
EST and CAST contain questions that are similar to, but not identical to, questions on the ASVAB. They are used to assess your likelihood of getting a qualifying AFQT score.
If you take one of these "mini-tests" and get low marks, you may not want to take the actual ASVAB until you've taken the time to study. In fact, many recruiters don't even plan an ASVAB unless they get a good EST or CAST score.
Pre-made object (AO) subtests are not included in any of the ASVAB paper versions; it is only included in the computer version. The test is available in more than 13,000 middle and high schools in the United States. Approximately 900,000 students take Form 18/19 ASVAB each year.
