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.

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).
Each year, many high school and postsecondary students take the free Armed Services Vocational Aptitude battery (ASVAB).  The ASVAB is the most widely used multiple-aptitude test battery in the world.  It consists of eight tests that measure your skills and abilities in the following areas:  General Science; Arithmetic Reasoning; World Knowledge; Paragraph Comprehension; Mathematics Knowledge; Electronics Information; Auto and Shop Information; Mechanical Comprehension.
In Medieval Europe, tales of knighthood and chivalry, the officer class of the period captured the popular imagination. Writers and poets like Taliesin, Chrétien de Troyes and Thomas Malory wrote tales of derring-do, featuring Arthur, Guinevere, Lancelot and Galahad. Even in the 21st century, books and films about the Arthurian legend and the Holy Grail continue to appear.
High school students can take the test in their sophomore, junior, or senior years, although scores from sophomore tests can’t be used for enlistment purposes. There is no charge to sit for the exam, and the results will have no impact on your high school academic record or your college application. This is a risk-free way to better evaluate your opportunities for the future after high school graduation.
Although concerned with research into military psychology, and particularly combat stress, and how it affect troop morale, often the bulk of military science activities is directed at military intelligence technology, military communications, and improving military capability through research. The design, development, and prototyping of weapons, military support equipment, and military technology in general, is also an area in which lots of effort is invested – it includes everything from global communication networks and aircraft carriers to paint and food.
You can't use the AR and MK score shown on your ASVAB Score Sheet. The Score Sheet shows "number correct" for your AR and MK Scores, because "number correct" is what is used for job qualifications. However, the military does not use this same score when computing the AFQT. They use the "weighted scores" of the ASVAB sub-tests for AR and MK. Harder questions in these areas get more points than easier questions. The "weighted scores" for AR and WK are not listed on the ASVAB score sheet given to you after the test.
The other written test format is the Student ASVAB which is given at high schools, vocational schools, or colleges. This test lasts approximately three hours. The Written Arithmetic Reasoning subtest of the ASVAB consists of 30 multiple choice questions, which must be answered in 36 minutes. Below are a few sample questions which are very similar to the actual questions you'll see on the ASVAB:

The President of the United States is the Commander in Chief, who is responsible for all final decisions. The Secretary of the Department of Defense (DoD) has control over the military and each branch - except the Coast Guard, which is under the Dept. of Homeland Security. With over 2 million civilian and military employees, the DoD is the world's largest "company."
During World War I, the need to break the deadlock of trench warfare saw the rapid development of many new technologies, particularly tanks. Military aviation was extensively used, and bombers became decisive in many battles of World War II, which marked the most frantic period of weapons development in history. Many new designs, and concepts were used in combat, and all existing technologies of warfare were improved between 1939 and 1945.
This advice, though well-intentioned, doesn’t address the needs of some new recruits who are interested in specific career fields but are worried about their test performance-especially in areas related to math comprehension. Potential recruits who feel deficient in math, language, or science skills should have a frank conversation with their recruiter to discuss possible refresher study or even supplemental classes in any self-perceived “problem areas” before taking the test.

If you’re planning on using your scores for military enlistment, you may be hoping to achieve a score that is high enough for a specific signing bonus. While it’s natural to want to do your best, putting extra pressure on yourself can cause unnecessary anxiety. Take a few deep breaths, relax, and remember that taking the test is only part of the entire recruitment process.
The ASVAB is routinely reviewed to eliminate any potential biases from questions and scoring. The exam underwent a major revision in 2002. Two years later, a renormalization of the percentile scoring system was performed to ensure that a 50 percent score represented performing better than 50 percent of all test takers. The 10-section ASVAB improves the matching of volunteers with available jobs and helps match job openings with qualified individuals.

The General Science section of the test covers earth, space, and physical and life sciences. Because science is such a vast and dynamic topic, focus your study on basic principles. This gives you a good foundation to work through any question that is asked of you. Typical questions may include: “Why is air less dense than water?” or “How do you convert Celsius temperature to Fahrenheit?” The CAT-ASVAB test asks 16 questions in 8 minutes, while the pencil-and-paper version asks 25 questions in 11 minutes.
Nobody wants to be stuck doing something they don’t like. That’s why we urge you to take advantage of our free practice tests and study guides.  Our ASVAB practice tests are formatted exactly like the real ASVAB test and will not only help ensure you have the knowledge to ace the real exam but will also prepare for the actual experience of sitting for the test.
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 United States has the world's largest military budget. In the fiscal year 2016, $580.3 billion in funding were enacted for the DoD and for "Overseas Contingency Operations" in the War on Terrorism.[6] Outside of direct DoD spending, the United States spends another $218 to $262 billion each year on other defense-related programs, such as Veterans Affairs, Homeland Security, nuclear weapons maintenance and DoD.
Again, the ASVAB is a wide-ranging exam covering many different areas. The designers of ASVAB practice tests, at least the high quality ones, know this and have spent time researching past tests to come up with practice tests that feature questions covering areas commonly tested for on the real exam. Thus, taking practice tests is a great way to focus on the material that matters most and avoid wasting your time studying content that likely won’t be on the test.
Under the Montgomery GI Bill, the Army, Navy, Air Force, Marine Corps and Coast Guard (and their Reserves and the National Guard) provide a cash education incentive to encourage you to join and serve a tour of duty. The Montgomery GI Bill (MGIB) provides up to 36 months of education benefits to eligible veterans for college, business, technical or vocational courses, correspondence courses, apprenticeship/job training and flight training. MGIB benefits may be used while on active duty or after a fully honorable discharge from active duty.

The various armed forces adopted all of those aspects in 1976. At that point in time, the test was in its written form rather than today’s more common form (computerized test format). The written form covers all of the previously mentioned areas as well, which is why both forms are still available. All-in-all that answers the question concerning the intention of the test.
