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.

**How were you at math in high school? This subtest of the Armed Services Vocational Aptitude Battery is going to put you to the test. It is filled with questions covering basic high school math. Unfortunately, that means there is a lot for this test to cover, which means you’ll have to do a lot of jumping from one math concept to the next during the course of this subtest. One way to get ready for these rapid switches is to take our practice test – but we’ll talk more about that later. Right now, let’s take a closer look at the Mathematics Knowledge subtest. On the Mathematics Knowledge subtest you will have 24 minutes to answer 25 questions on the paper version of the ASVAB. On the CAT-ASVAB you will have 20 minutes to answer 16 questions. This subtest is counted as part of your Armed Forces Qualification Test score, so you will want to perform as well as you can. A good score on this subtest is also important to qualify for a number of military jobs.**

Take timed tests. Letting time get away from you is a sure fire way to get yourself into trouble. Timed sample tests like the ones on this site can get you used to dealing with the allowed timing for each section so you can learn to maintain a pace that will get you through each section. If you’re taking the paper version of the test, feel free to skip a question if it’s got you stumped, but be sure to come back to complete it. The computerized test doesn’t give you an option to skip questions, so have a strategy in place for questions you can’t solve relatively quickly.

*The Armed Services Vocational Aptitude Battery (ASVAB test--also known as the AFQT (Armed Forces Qualification Test). This is the score used by the recruiter to determine a potential recruit’s enlistment eligibility, assign a recruit to a military jobs, and aid students in career exploration. The AFQT is actually a subset of the ASVAB - only with scores of four of the ten test sections calculated.*

_{For applicants with a high school diploma, the minimum required AFQT score to enlist in the Coast Guard is 40, while GED applicants must score a 50. GED recruits make up only 5 percent of each year's Coast Guard class. If an applicant's ASVAB subtest scores qualify for a specific job that is in demand, use of a waiver is possible if the applicant agrees to enlist for that job. }

^{The ASVAB test can be taken at your school or a MEPS (Military Entrance Processing Stations) or MET (Mobile Examination Test) sites. When the ASVAB is administered at your school, it is usually part of the Student Testing Program or Career Exploration Program. When the ASVAB is given at MEPS or MET sites, it is part of the Enlistment Testing Program. The ASVAB test content is the same no matter where you take it, except that you will not have to take the Assembling Objects test if you take the test at your school (as part of the Student Testing Program). When you take the test in the Student Testing Program you will receive three composite scores (Verbal Skills, Math Skills, and Science and Technical Skills). When you take the ASVAB as part of the Enlistment Testing Program, you will receive an AFQT (Armed Forces Qualification Test) score and Service composite scores. These scores are used for assigning your military job. }

^{AFQT (Armed Force Qualification Test) score: This score is reported in the form of a percentile rank and is calculated by adding the scores that you have received for the 4 sub-tests, viz, Mathematics Knowledge, Arithmetic Reasoning, Paragraph Comprehension and Word Knowledge. The total score that you receive for these sub-tests is then compared to the scores that other candidates taking a similar format of the test have received. Then you receive a percentile rank that can range anywhere from 1 to 99. For example, if you receive a rank of 45 percentile then you have scored more than 45 students, but 55 students have scored more than you. }

AFQT scores are reported as percentiles between 1 and 99, and the score is relative: Your AFQT score indicates how well you did compared to the scores of a reference group. For example, if you score 71, that means you scored as well as or better than 71 percent of those in the reference group. If you score 50, your score is exactly average compared to the reference group. According to the Army, about half the population scores at or above 50, and about 16 percent of the population scores at or above 60.

### 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.

**The Word Knowledge subtest of the Armed Services Vocational Aptitude Battery measures your vocabulary knowledge. It is one of the four subtests, along with paragraph comprehension, arithmetic reasoning and mathematics knowledge, which are used to determine your Armed Forces Qualification Test score, which in turn determines your eligibility for military service. In addition, a good score on this section is required for a number of military jobs, everything from the obvious journalist position to the maybe not so obvious firefighter position. In other words, this is an important section of the ASVAB to do well and you should be sure to devote sufficient study time to preparing for this subtest. On the Word Knowledge subtest you will have 8 minutes to answer 16 questions if you take the CAT-ASVAB. If you take the paper ASVAB, you will have 11 minutes to answer 35 questions. On this test, you will be required to both differentiate words based on their spelling and to know what various words mean.**

**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.**

*General Science tests the ability to answer questions on a variety of science topics drawn from courses taught in most high schools. The life science items cover botany, zoology, anatomy and physiology, and ecology. The earth and space science items are based on astronomy, geology, meteorology and oceanography. The physical science items measure force and motion mechanics, energy, fluids, atomic structure and chemistry.*

*Master the ASVAB is our 5th best overall prep book on our list of the best ASVAB prep books. One positive about this review guide is the diagnostic test. This diagnostic test is very good for helping you to figure out your weaknesses. When you know your weaknesses you can focus your preparation on those things that you can improve to get a higher score on the exam. This really allows you to save time studying since you don't need to practice the topics that you already have a good grasp of.*

*The vast majority of people who take the CAT-ASVAB test finish it as the time constraints are not very aggressive. However, if a respondent isn’t able to finish in time, the remaining unanswered questions are scored as if the respondent had answered them randomly. This is obviously not an ideal way to finish up the test and most often results in even poorer scores.*

*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.*

Circles have a radius which measures the length from the center of the circle to any point on its curve. The diameter is the length, through the center, from one point on the curve to another and equals radius x 2. The circumference is the length around the curve and is equal to 2 x pi x radius (2πr) or pi times diameter (πd). The area of a circle is pi times radius squared (πr2).

*The questions that have a tendency to arise rather quickly are something along the lines of “why is this test so important?” and “What is the overall purpose of this test?” Well, first it is important to define the actual test and to assess the colorful history of the test. The Armed Services Vocational Aptitude Battery test (ASVAB) is a test that was officially formatted in 1968 with the intention of mentally preparing soldiers with knowledge that identifies with the following:*
