A switch is a device for opening and closing an electric circuit – when the switch is open, no current flows.  Switches are categorized by the number of poles and throws they provide with the number of poles designating the number of electrical circuits the switch can control and the number of throws indicating the number of connections the switch can make between those circuits.
GED holders who earn 15 college credits 100 level or greater are considered equivalent with those holding high school diplomas, so that they need only the Tier I score to enlist. Eligibility is not determined by score alone. Certain recruiting goal practices may require an applicant to achieve a higher score than the required minimum AFQT score in order to be considered for enlistment. Rules and regulations are subject to change; applicants should call their local recruiting center for up to date qualification information.[4][5]

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.
Unlike other vocabulary building books which just provide a lengthy list of words and definitions, Barron's organizes 800 words into sentence completion exercises of 10 words at a time which makes integrating these words into your everyday vocabulary much easier than just going down a list and relying on rote memorization. If you have an average vocabulary and and are looking to do well on the ASTB, Barron's Essential Words for the GRE is a great addition to your study material.

Reading page after page of boring content can cause the strongest minds to wander. Taking practice tests are a great way to break up the monotony of studying. Taking a practice test challenges you and keeps you interested in the material. Then you can review your test results and go over the questions you got wrong committing the right answer to memory. It’s a great, streamlined way to learn.
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.
The format of a paragraph is also a key component of mathematical reasoning. A physics equation, for instance, will be formatted far differently than a simple algebraic equation; a physics word problem will likely involve a vehicle of some type (car, train, plane, etc.), while a simple addition equation may involve a myriad of different situations in many different contexts. To determine the nature of the equation, you must first identify the format and context of the paragraph. From there, you can combine the buzzwords and numbers to form a completed, simplified equation.

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.

Non-Prior Service applicants with AFQT scores less than 50 must have a Tier I education status (i.e... Traditional high school diploma graduate, 15 semester hours of accredited college credit or other approved avenues - check with your Navy Recruiter for your education Tier status). If you are Prior Service, you may enlist with ASVAB scores obtained from your previous enlistment, regardless of your AFQT score, provided you are enlisting in the equivalent Navy job, or meet line score eligibility for the rating you are enlisting. Prior Service applicants not line score eligible shall be re-administered the ASVAB and processed with the new line scores, regardless of the AFQT score obtained. Other Service Veterans (OSVETS) with military training/skills directly convertible to a Navy rating may enlist in the directly convertible rating, regardless of your previous AFQT or line scores.
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.

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.
CliffNotes has a pre-test and post-test for every section in the book including numerous practice problems for each type of math question. By the time you finish this book, you will have covered hundreds of math problems including some of the most common problems found on standardized tests. Although this book was not written exclusively for the ASTB many of the questions found

Mathematics Knowledge tests the ability to solve problems by applying knowledge of mathematical concepts and applications. The problems focus on concepts and algorithms, and involve number theory, numeration, algebraic operations and equations, geometry, measurement and probability. Mathematics Knowledge is one factor that characterizes mathematics comprehension; it also assesses logical thinking.
Varsity Tutors’ ASVAB Learning Tools can also help you work in groups, if you so choose. They let you post results on social media so others can see how you did. Many people actually share their progress over time and make this an opportunity to help one another; they’ll even compete in practice tests to make them more fun. The ASVAB practice tests provide a sample of the material you’ll be asked to work with on test day. They are structured in a precise, non-intimidating format with honest and detailed feedback. The study process is made simpler and more efficient while also facilitating a more personalized process of studying.

Bar none this is the best study guide available for those who aren't particularly adept at math or haven't taken a math class in a long time. CliffNotes Math Review for Standardized Tests covers everything from arithmetic and algebra to geometry and word problems. This book manages to break down increasingly complicated math problems in such a way that is very easy to understand. 
Once the ASVAB is over, participants are given a score. This score is used by recruiters to determine which branch of the military would be a good fit for a given test-taker. The most important score for the ASVAB for military purposes is the AFQT score. The AFQT score looks at results from the following sections: Arithmetic Reasoning (AR), Math Knowledge (MK), and multiplies the Verbal Composite (VE) score by two. This is because the Verbal Composite Score is composed of both the Word Knowledge and the Paragraph Comprehension scores. Each branch of the military requires a different minimum AFQT score for its members. For the army and marines, this number is 31, for the navy 35, the air force 36, and the coast guard 45. Therefore, this test is a crucial part of any military career, and can determine potential jobs and advancement opportunities. Along with advancement opportunities come higher salaries and greater benefits, which makes the ASVAB an essential element for prospective military service personnel at any level.
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.
Unfortunately this study guide does not have any full length practice tests which should be an essential part of your study regimen. However, this guide does provide a few sample questions for each section which, quite frankly, isn't enough. The best use for this book would be to study the introductory lessons in order to create a baseline for you to expand your knowledge, and to use another resources for practice tests. To be fully prepared for the ASVAB, it is best to draw on several sources and the ASVAB Study Guide 2014 should definitely be one of those sources.
Army.mil says of ASVAB/PiCAT testing, “The ASVAB is usually given in schools by test administrators from the federal government. Schools determine where and when the ASVAB will be given. See your academic advisor for more information. If you’re not currently in school, contact your local recruiter.” Test administration and scheduling procedures are handled differently by each branch of the military.
The Word Knowledge section of the test gauges your ability to recognize the meaning of words both individually and when used in a sentence. A question may be phrased as, “‘Antagonize’ most nearly means: embarrass, struggle, provoke, or worship.” Because there are so many words in the English language, you may find it difficult to study the specific words on the test. However, striving to improve your language and vocabulary usage with a practice test like this one can help you not only in preparing for the ASVAB test but also in your career and personal life. The CAT-ASVAB test has 16 questions in 8 minutes, while the paper-and-pencil version has 35 questions in 11 minutes.

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 Arithmetic Reasoning section of the ASVAB test focuses on word problems and delivers mathematical questions and equations in a format that must be synthesized. These may not only be simple questions involving basic multiplication, but may also be as complex as completing a physics equation listed in paragraph or word-block format. When deconstructing these word problems, pay close attention to all aspects of the question, including all numbers mentioned, buzzwords, and the format of the paragraph itself. The following pointers will give you a more in-depth analysis of each component of word problems.
Unlike enlisted applicants, officer candidates are judged solely on their General-Technical line score and not their AFQT score. Remember, the General-Technical score is comprised of the sum of Paragraph Comprehension, Word Knowledge, and the Arithmetic Reasoning subtests. The GT score requirement for prospective officers for each branch is detailed below. Note, the Air Force and the Navy do not use the ASVAB for officer applicants and rely on their own exams. 
There are nine sections on the exam: General Science, Arithmetic Reasoning, Word Knowledge, Paragraph Comprehension, Mathematics Knowledge, Electronics Information, Automotive and Shop Information, Mechanical Comprehension, Assembling Objects, and Verbal Expression. The time limits for each section range from 10 – 36 minutes; the entire exam takes three hours.
One set of ASVAB scores – Career Exploration Scores – tells you your current strengths in verbal, math, science, and technical skills.  The scores allow you to compare your test performance with that of other students at your grade level and can help you determine your readiness for further education and training in different career areas.  You will also receive a Military Entrance Score that is important for entry into the Armed Services.  You can discuss your score with a military recruiter.

There are three different versions of the ASVAB: the Computer Adaptive Test (CAT), the Student version, and the Paper & Pencil version. The Student version of the ASVAB is remarkably similar to the Paper & Pencil version, and is typically administered to high school students across the country. For the purposes of this website, we will focus on the CAT and the Paper & Pencil versions exclusively.
Additionally, many ASVAB practice tests have a section explaining the answer choices. It can be tempting to read the explanation and think that you now have a good understanding of the concept. However, an explanation likely only covers part of the question’s broader context. Even if the explanation makes sense, go back and investigate every concept related to the question until you’re positive you have a thorough understanding.
Auto and Shop Information tests aptitude for automotive maintenance and repair, and wood and metal shop practices. The test covers several areas commonly included in most high school auto and shop courses, such as automotive components, automotive systems, automotive tools, troubleshooting and repair, shop tools, building materials, and building and construction procedures.
