If you are interested in joining the military then the Armed Services Vocational Aptitude Battery (ASVAB) may, very well be, the most important test you'll ever have to take. Spanning everything from job selection and pay grade to serving in the branch of your choice or even serving at all, the importance of the ASVAB cannot be overstated. The primary function of the ASVAB is to determine if recruits are qualified for service, and if they possess the skills necessary for receiving training in a variety of military occupations.

Like other military aptitude tests, the ASVAB measures general knowledge from a wide range of categories which can make studying for it seem hopeless at times. Fortunately there are a number of books and study guides out there to help you do well and increase your score. Although this list isn't comprehensive it does include the most helpful and relevant study guides available for succeeding on the ASVAB and, by extension, allowing you to start your career serving in the U.S. Armed Forces. 
My recruiter told me about this book so I ordered it and got it 3 days later from the Military Bookstore. I got this book and it is awesome. The cd works great and every thing I needed and more to help me was in there. I recommend this book to everyone who is thinking of going in the service and wants to get a real job! GET THIS BOOK AND SCORE HIGH!!!!”
In complete honesty, one can say that the test identifies with an entire life's worth of knowledge. It essentially pulls from 3 different aspects. First, it draws from concrete facts that were acquired from all areas of a person's educational career. Secondly, it draws from a person’s ability to comprehend and use context clues to make assumptions. Lastly, it draws from a person’s physical/verbal skills to see if they can properly administer those more physical aspects. Overall this is why people have identified it as the “SAT on steroids.”
In order to take the ASVAB at a MEPS for enlistment purposes, an individual will need to speak with a recruiter and schedule a time to take the test. ASVAB testing at a MEPS is self-paced and taken on a computer, and it may be retaken after a one-month waiting period.  Entitled the CAT-ASVAB, the test is adaptive – meaning it adapts to your ability level.
Arithmetic reasoning refers to the process of solving math word problems – you know those questions you had in elementary, middle and high school that might involve two trains traveling at different speeds or determining how many different pieces of fruit Tommy brought home from the grocery store. Whether you enjoy these types of problems or dread them, there is a process you can use to make solving them quicker and easier. Your test administrator will provide you with scratch paper and a number two pencil for this portion of the ASVAB. Calculators are not allowed. If you are taking the pencil-and-paper test, you will 36 minutes to answer 30 questions and if you are taking the computer version, you will have 39 minutes to answer 16 questions.
The Armed Forces Qualification Test (AFQT) score is derived from only four of the ASVAB subtests: Paragraph Comprehension (PC), Word Knowledge (WK), Mathematics Knowlege (MK), and Arithmetic Reasoning (AR). Your AFQT is based on a percentile system with scores ranging from 1 through 99. An average score of 50 means you score better than 50% of all other test takers. The AFQT score is by far the most important score for enlisted applicants since it determines whether you can join the military service of your choice or if you are even eligible to join the military.
Ecology is the study of interactions between organisms and their environment. Regions that share a similar climate and soil type (and, therefore, similar animal and plant life) are called biomes and house a community of species that each belong to a population.  This combination of biome and community make up an ecosystem that consists of predators that utilize other living organisms as food, prey that becomes food to predators, and parasites that lives in or on another organism and takes nutrients from its host.
It had sections on the mechanical portion of the ASVAB that were very helpful as well as Mathematical practices that served as a great refresher for me. The strategies were also very helpful and gave me confidence going into the test. After going through the book and taking the practice exams, I feel I was well prepared for the ASVAB test. My score almost doubled from my previous attempt at the test after using this guide.
One flaw of this review guide is that the summary is not as comprehensive as other prep guides. At only 324 Pages, this prep book does not have enough length to meticulously go through all of the topics. If you are looking for an in-depth rundown you may need to supplement this prep book with another review guide. If you just need a quick overview, however, this guide may be perfect for you.

The ASVAB is a multiple choice test and is broken down into eight areas. Each section has its own score, and are combined to come up with your composite score. It’s scored on a percentile basis, so 99 is the highest possible score. Different branches of the military will have different minimum composite scores, and those will vary within each branch by different job. The higher you score, the more jobs and options you’ll qualify for. If you don’t take it in high school, you’ll take the test at your nearest Military Entrance Processing Station, or at an armory or recruiting station. It’s timed, and it takes about three and a half hours to complete.
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.

As a general rule of thumb, anything over an 85 on the ASVAB will qualify you for nearly any position in the armed forces. But there are slight breakdowns within each score. For example, in order to qualify for Surveillance and Communications (SC) in the Army, Word Knowledge, Paragraph Comprehension, Arithmetic Reasoning, Auto & Shop and Mechanical Comprehension all require high marks. Though scoring an 85 or above would guarantee you scored in a high enough percentile to qualify for SC.
Again, we must stress that there is no passing or failing score on the exam. The test is a measure of aptitude and provides percentile rankings to indicate your performance compared to other test takers. However, different branches of the military do have minimum score requirements for enlistment. This means that it’s important to make sure you’re prepared for test day, and that’s where a practice test will prove valuable.

The ASVAB is utilized by every branch of the armed forces for vetting enlisted applicants, and is used by the US Army, Marine Corps, and the Coast Guard for selecting officer applicants.

Standard scores: The battery consists of a set of 9 to 10 sub-tests, depending on whether you are taking the paper format or the computerized format of the test. The score that you receive for each of the sub-test is reported separately and the sum of these scores is reported as a standard score. If you take the paper format of the test, then the maximum total standard score that you can get is 225. If you take the CAT-ASVAB, then the highest standard score achievable is 145.

The Armed Services Vocational Aptitude Battery, or ASVAB, scores are a part of what determines your ability to enlist in the Army, Air Force, Navy, Marine Corps or Coast Guard. Your ASVAB score includes your Armed Forces Qualification Test (AFQT) score. For high school graduates, the required score is usually in the lower 30s, while those with a GED are usually required to score at least a 50. A "good" score for those who have graduated high school is considered to be a 35. However, each branch has its own minimum score necessary for enlistment, and the higher you score, the more jobs you will be qualified for in your branch of service.
According to the ASVAB testing site, there are between eight and nine subtests, depending on which version of the ASVAB a soldier takes. On some of the ASVAB tests, the Auto and Shop subtests are combined. The subtests and their abbreviations are General Science (GS), Arithmetic Reasoning (AR), Word Knowledge (WK), Paragraph Comprehension (PC), Mathematics Knowledge (MK), Electronics Information (EI), Auto Information (AI), Shop Information (SI), Mechanical Comprehension (MC). Each section has between 15 and 35 questions.

According to the ASVAB testing site, the branches of the military use the Armed Forces Qualification Test (AFQT) score to place soldiers into training groups. The AFQT score is comprised of four of the ASVAB subtests: the Arithmetic Reasoning (AR), Mathematics Knowledge (MK), Paragraph Comprehension (PC), and Word Knowledge (WK). The AFQT score is computed on a percentile score from 1 to 99; the higher the percentile score, the more likely a soldier is to get a military job he wants. In addition, branches of the military use individual subtest scores, such as Auto and Shop, to place soldiers for individual training.
