Obviously, the most important way to prepare to take the test is to spend plenty of time reviewing practice test questions. Look at questions from all sections of the test, but pay special attention to questions on the Word Knowledge, Paragraph Comprehension, Arithmetic Reasoning, and Mathematics Knowledge sections, which will be used to calculate your Armed Forces Qualification Test (AFQT) score for enlistment.
In exchange for a service commitment, the Reserve Officers' Training Corps (ROTC) program provides you with money for college while you're in school. You must take one military science course along with your other college courses and, upon graduation, enter the service as a commissioned officer. (There is no military commitment for the first year in ROTC, allowing you to pursue ROTC on a trial basis to see if ROTC is for you.) Full ROTC scholarships pay for almost all tuition, fees and books charges for four years of college. ROTC scholarships also come in one, two and three-year lengths. For more information, call 1-800-USA-ROTC (Army), 1-800-USA-NAVY (Navy), 1-866-423-7682 (Air Force) and 1-800-MARINES (Marines).
Command over the U.S. Armed Forces is established in the Constitution. The sole power of command is vested in the President by Article II as Commander-in-Chief. The Constitution presumes the existence of "executive Departments" headed by "principal officers", whose appointment mechanism is provided for in the Appointments Clause. This allowance in the Constitution formed the basis for creation of the Department of Defense in 1947 by the National Security Act. The DoD is headed by the Secretary of Defense, who is a civilian and member of the Cabinet. The Defense Secretary is second in the U.S. Armed Forces chain of command, with the exception of the Coast Guard, which is under the Secretary of Homeland Security, and is just below the President and serves as the principal assistant to the President in all defense-related matters.[16] Together, the President and the Secretary of Defense comprise the National Command Authority, which by law is the ultimate lawful source of military orders.[17]
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.
The ASVAB Career Exploration Program provides tools developed by the Department of Defense (DoD) to help high school and post-secondary students across the nation learn more about career exploration and planning. Since the mid-1990’s, the ASVAB Career Exploration Program has provided high quality, cost-free career exploration and planning materials and services annually to approximately 14,000 of the nation’s high schools. You can prepare by taking ASVAB Practice Tests – many of which are available online.
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."
The scores from the other tests are used to determine what type of specialty you might be best suited for.  These "composite" scores (also known as line scores, MOS scores, or aptitude area scores) are calculated by adding together combinations of the different sub test standard scores. These composite scores are then used to determine which different military jobs (aka Military Occupational Specialties or MOS) may be the best fit for you.  Each branch of the military will have their own approach to these composite scores.

The profession of soldiering as part of a military is older than recorded history itself. Some of the most enduring images of the classical antiquity portray the power and feats of its military leaders. The Battle of Kadesh in 1274 BC was one of the defining points of Pharaoh Ramses II's reign, and is celebrated in bas-relief on his monuments. A thousand years later, the first emperor of unified China, Qin Shi Huang, was so determined to impress the gods with his military might, he was buried with an army of terracotta soldiers.[1] The Romans were dedicated to military matters, leaving to posterity many treatises and writings, as well as a large number of lavishly carved triumphal arches and victory columns.

Militaries often function as societies within societies, by having their own military communities, economies, education, medicine, and other aspects of a functioning civilian society. Although a 'military' is not limited to nations in of itself as many private military companies (or PMC's) can be used or 'hired' by organisations and figures as security, escort, or other means of protection; where police, agencies, or militaries are absent or not trusted.

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.

I just had to thank you guys for the test prep! I am a former Marine that decided to reenter the military and much to my surprise, I had to retake the AFQT!!! The last time I even looked at a math or English problem had to be at least 6 or seven years ago. I bought the guide as a last minute prep, I mean maybe 5 hours before the test. Like I said, I didn't even know I had to retake the test and had ZERO preparation! The job I wanted required a pretty high GT score and I was nervous about even passing the test let alone receiving the score I needed. I read the guide through only once before test time and needless to say, the only way I passed was thanks to your refresher!! Sgt. Brian
In addition to the ASVAB's AFQT, each branch has military occupational specialty, or MOS, scores. Combinations of scores from the nine tests are used to determine qualification for a MOS. These combinations are called "aptitude area scores", "composite scores", or "line scores". Each of the five armed services has its own aptitude area scores and sets its own minimum composite scores for each MOS.
The Armed Forces Qualification Test (AFQT) derives from the more comprehensive, 10-subtest Armed Services Vocational Aptitude Battery (ASVAB). Scores on the four ASVAB math and verbal subtests are used to calculate an AFQT score, which determines whether an individual is generally qualified to enlist. Performance on all 10 ASVAB subtests, meanwhile, ascertains an enlistee's qualifications for specialized work within the military and possible incentives for enlistment.
In addition to the AFQT, the military also includes additional composite scores, often called 'line scores.' These scores are based on variations of the ASVAB's ten subtests and are required for certain military careers. For example, an Army Clerical (CL) score is determined by looking at an individual's Word Knowledge (WK), Paragraph Comprehension (PC), Arithmetic Reasoning (AR) and Mathematics Knowledge (MK) scores. Note that the subtests considered for different careers can vary depending on the military branch.
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.
If you didn't earn a score that was high enough to be accepted to your chosen branch of the military, or if you didn't earn a line score high enough to qualify for a desired career option, then you may retake the ASVAB. You must wait a full month before you can take the ASVAB a second time. If you wish to take the test a third time, you must wait another month from the date of your second attempt. After the third attempt, there is a waiting period of 6 months before you can take the test again.
I purchased your AFQT Secrets file, and I just wanted to let you know that I got a 99% on my test. I just got my job of choice today of Military Intelligence Analyst, and I am now on the road to my future career in the CIA or NSA. I just want to thank you again, and hope you have continued success in your ventures. Sincerely, Paul L. U.S. Army (Intel Analyst
The best way to answer questions in this section is to read each paragraph twice before you answer. First, read it quickly to get the main idea. Next, read it again, paying more attention to the details that relate to the main point. Then, read all of the questions and refer back to the paragraph to help you choose the best answer. If you take this approach, you will be more relaxed and efficient, and less likely to get thrown off the track by being nervous.
The majority of people who complete the exam have little intention of entering the military. However, it’s important to keep in mind that the United States military is actually one of the nation’s largest employers. If you’re undecided about your future after high school graduation, taking the test can give you a better picture of your options in both civilian and military life.

Personnel may be posted to bases in their home country or overseas, according to operational need, and may be deployed from those bases on exercises or operations anywhere in the world. During peacetime, when military personnel are generally stationed in garrisons or other permanent military facilities, they mostly conduct administrative tasks, training and education activities, technology maintenance, and recruitment.

The next requirement comes as a fairly basic need for the military to identify possible threats it may be called upon to face. For this purpose, some of the commanding forces and other military, as well as often civilian personnel participate in identification of these threats. This is at once an organisation, a system and a process collectively called military intelligence (MI).

The process of allocating resources is conducted by determining a military budget, which is administered by a military finance organisation within the military. Military procurement is then authorised to purchase or contract provision of goods and services to the military, whether in peacetime at a permanent base, or in a combat zone from local population.
My name is Chris. I used the AFQT Secrets study guide for five days. I am ex-military retaking the AFQT to reenlist. I just want to say thank you for developing this study guide. My test score in 1988 was 51, today my test score is 89. I would just like to add that I have an A.A.S. Degree, but no math skills above basic high school math. This is where I was lacking, the study guide made it so easy to understand. Like you said this program is worth 100's of dollars. To me 1,000's!! THANKS, Chris G.
Test scores provide only one measure of your skills and abilities.  Test scores and grades, combined with information about your interests, values, skills, and achievements may help you select appropriate occupations for career exploration.  As you explore careers, you can compare your skills with the skill requirements of occupations in which you are interested.
