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.

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.
Prospective service members are often recruited from high school or college, the target age ranges being 18–35 in the Army, 18–28 in the Marine Corps, 18–34 in the Navy, 18–39 in the Air Force and 18–27 (up to age 32 if qualified for attending guaranteed "A" school) in the Coast Guard. With the permission of a parent or guardian, applicants can enlist at age 17 and participate in the Delayed Entry Program (DEP), in which the applicant is given the opportunity to participate in locally sponsored military activities, which can range from sports to competitions led by recruiters or other military liaisons (each recruiting station's DEP varies).

Figure out which areas to focus on based on your career goals. If you’re not interested in a job requiring a score on the Mechanical Comprehension subtest, you don’t need to worry about doing well on that subtest. If you don’t need to worry about mechanics, don’t bother preparing for that section. Spend the time on Word Knowledge or Arithmetic Reasoning.
Military law introduces offences not recognised by civilian courts, such as absence without leave (AWOL), desertion, political acts, malingering, behaving disrespectfully, and disobedience (see, for example, Offences against military law in the United Kingdom).[23] Penalties range from a summary reprimand to imprisonment for several years following a court martial.[23] Certain fundamental rights are also restricted or suspended, including the freedom of association (e.g. union organizing) and freedom of speech (speaking to the media).[23] Military personnel in some countries have a right of conscientious objection if they believe an order is immoral or unlawful, or cannot in good conscience carry it out.
Jobs in the Marine Corps are referred to as”MOS” (short for Military Occupational Specialty). To find the MOSes you qualify for, the Marine Corps organizes your ASVAB subtest scores into various groups known as line scores. The ASVAB subtests are: General Science (GS); Arithmetic Reasoning (AR); Word Knowledge (WK); Paragraph Comprehension (PC); Numerical Operations (NO); Coding Speed (CS); Auto and Shop Information (AS); Mathematics Knowledge (MK); Mechanical Comprehension (MC); Electronics Information (EI); and Sum of Word Knowledge and Paragraph Comprehension (VE). It’s important to remember that as Numerical Operations (NO) and Coding Speed (CS) subtests are phased out, some line scores may be updated.

These supply points are also used to provide military engineering services, such as the recovery of defective and derelict vehicles and weapons, maintenance of weapons in the field, the repair and field modification of weapons and equipment; and in peacetime, the life-extension programmes undertaken to allow continued use of equipment. One of the most important role of logistics is the supply of munitions as a primary type of consumable, their storage, and disposal.
Because most of the concepts and methods used by the military, and many of its systems are not found in commercial branches, much of the material is researched, designed, developed, and offered for inclusion in arsenals by military science organisations within the overall structure of the military. Military scientists are therefore found to interact with all Arms and Services of the armed forces, and at all levels of the military hierarchy of command.
The exam is not a “pass or fail” test. Your score in each area reflects your own unique abilities. Of course, you will want to study with the aim of doing your best so that you can qualify for a job that fits your skills and career interests. Your AFQT score is compared to the scores of other recruits in the 18-23 year age bracket to see how your potential measures up.
An important part of the military intelligence role is the military analysis performed to assess military capability of potential future aggressors, and provide combat modelling that helps to understand factors on which comparison of forces can be made. This helps to quantify and qualify such statements as: "China and India maintain the largest armed forces in the World" or that "the U.S. Military is considered to be the world's strongest".[29]
Just as the President, the Secretary of Defense, and the Secretary of Homeland Security, are in charge of the entire military establishment, maintaining civilian control of the military, so too are each of the Defense Department's constitutive military departments headed by civilians. The four DoD branches are organized into three departments, each with civilian heads. The Department of the Army is headed by the Secretary of the Army, the Department of the Navy is headed by the Secretary of the Navy and the Department of the Air Force is headed by the Secretary of the Air Force. The Marine Corps is organized under the Department of the Navy, however it is still considered a separate and equal service. The Coast Guard is under the Department of Homeland Security and receives its operational orders from the Secretary of Homeland Security. However, the Coast Guard may be transferred to the Department of the Navy by the President or Congress during a time of war, thereby placing it within the DoD.[19]

A graphic view of the increasing trend in AFQT performance of accessions from FY 1981 through FY 1992 is provided in Figure 2.8. The more significant gains were in Categories I to IIIA, where the percentages increased from 47 percent in FY 1981 to 75 percent in FY 1992. Conversely, there has been a steady decline in the percentage of Category IIIB accessions. Most dramatic has been the decrease in accessions who score in Category IV—from 33 percent in FY 1979 to one percent or less since FY 1991. There has been a gradual decline in the percentage of accessions in Categories I to IIIA in the last seven years, from 75 to 65 percent.
8. Use the following passage to answer questions 8 and 9. Harry went to the drugstore and purchased band-aids, pain relievers and cold medication. He also picked up two prescriptions. He then stopped by the hardware store and bought nails, screws and a first aid kit. Finally, he went to the grocery store and bought orange juice, flour and eggs. Where did Harry buy the first aid kit?
If school district or open-enrollment charter school has entered into a prior contract under which a vocational aptitude test that does not comply with the requirements for an alternative test outlined above, then the school district, open-enrollment charter school, or high school may elect not to provide the ASVAB for the term of the contract. On the expiration of the contract term, the requirements outlined in this letter become applicable to the school district, open-enrollment charter school or high school.
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.
The Armed Services Vocational Aptitude Battery is the most widely used multiple-aptitude test battery in the world. As an aptitude test, the ASVAB measures your strengths, weaknesses, and potential for future success. The ASVAB also provides you with career information for various civilian and military occupations and is an indicator for success in future endeavors whether you choose to go to college, vocational school, or a military career.

The ASVAB site goes on to explain that “after the final ability estimate is computed, it is converted to a standard score on the ASVAB score scale that has been statistically linked to the ability estimate through a process called equating. Equating studies are conducted for every paper and pencil ASVAB form to ensure that scores have the same meaning regardless of which test form the examinee receives.”

While considered part of the non-commissioned officer corps by law, senior non-commissioned officers (SNCOs) referred to as chief petty officers in the Navy and Coast Guard, or staff non-commissioned officers in the Marine Corps, perform duties more focused on leadership rather than technical expertise. Promotion to the SNCO ranks, E-7 through E-9 (E-6 through E-9 in the Marine Corps) is highly competitive. Personnel totals at the pay grades of E-8 and E-9 are limited by federal law to 2.5 percent and 1 percent of a service's enlisted force, respectively. SNCOs act as leaders of small units and as staff. Some SNCOs manage programs at headquarters level and a select few wield responsibility at the highest levels of the military structure. Most unit commanders have a SNCO as an enlisted advisor. All SNCOs are expected to mentor junior commissioned officers as well as the enlisted in their duty sections. The typical enlistee can expect to attain SNCO rank after 10 to 16 years of service.
Although mostly concerned with the military transport, as a means of delivery using different modes of transport; from military trucks, to container ships operating from permanent military base, it also involves creating field supply dumps at the rear of the combat zone, and even forward supply points in specific unit's Tactical Area of Responsibility.
All of the branches work together during operations and joint missions in Unified Combatant Commands, under the authority of the Secretary of Defense with the typical exception of the Coast Guard. Each of the Unified Combatant Commands is headed by a Combatant Commander, a senior commissioned officer who exercises supreme command authority per 10 U.S.C. § 164 over all of the forces, regardless of branch, within his geographical or functional command. By statute, the chain of command flows from the President to the Secretary of Defense to each of the Combatant Commanders.[22] In practice, the Chairman of the Joint Chiefs of Staff often acts as an intermediary between the Secretary of Defense and the Combatant Commanders.

The Mathematics Knowledge section of the exam measures your knowledge of various math areas, such as algebra and geometry. You may be asked to find the square root of a number or the volume of a brick with given dimensions. Algebraic problems may require finding the value of “y” in a given equation. A review of math symbols—such as ≠, ≤, and √—can help you solve the given problems much faster, and using our ASVAB math study guide to practice answering the algebra and geometry questions on the test can help increase your overall AFQT score. The CAT-ASVAB has 16 questions in 20 minutes; the paper-and-pencil version has 25 questions in 24 minutes.
The ASVAB also known as the Armed Services Vocational Aptitude Battery is a test that measures your aptitude which is how well you do something.  A common mistake by most people is thinking that it is a measure of you IQ. Many people either forget this or don’t know this and they get worked up about the exam.  Saying that, it is also important to take a ASVAB sample test to insure you know what type of questions will be asked.    Another thing to keep in mind is every person in the armed forces has to take the exam and you are not being called out to take it. 
Sergeant Leigh Ann Hester became the first woman to receive the Silver Star, the third-highest U.S. decoration for valor, for direct participation in combat. In Afghanistan, Monica Lin Brown was presented the Silver Star for shielding wounded soldiers with her body.[45] In March 2012, the U.S. military had two women, Ann E. Dunwoody and Janet C. Wolfenbarger, with the rank of four-star general.[46][47] In 2016, Air Force General Lori Robinson became the first female officer to command a major Unified Combatant Command (USNORTHCOM) in the history of the United States Armed Forces.[48]
