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.

According to Military.com, there are three versions of the ASVAB. One, the CAT-ASVAB (CAT stands for Computerized Adaptive Test) is taken only on the computer and is available only at military processing stations for enlisting soldiers. The second type of ASVAB is the P&P ASVAB, which is the Paper and Pencil ASVAB. This test is also called the S-ASVAB on some websites. S stands for student. The paper and pencil ASVAB is for high school and college students who may never enlist. The third ASVAB is the MET-ASVAB (Mobile Examination Test), which is given only to enlisted soldiers at a mobile testing center.
Line Scores are composed of the sum of particular combinations of ASVAB subtests. These scores are used to determine if enlisted applicants are qualified to be trained in a specific military occupation. A type of line score, known as the General-Technical score, is used to determine if prospective officer candidates are qualified to join a specific branch of the military and be enrolled in officer training. Line Scores are not used to determine eligibility for particular military occupations for officer candidates. Job availability for officer candidates is based on their performance in Officer Candidate School (OCS).

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.

My student and I like how there are videos in between. This allows him to visually see and hear about the information in a different way. It breaks up the book and makes it more interesting. I also like the setup of the book. So far, he has taken the Word Knowledge practice test after reviewing and received a score of 32/35, which seems to be a very good score. He wants to join the National Guard but did not score high enough on the ASVAB the two times he took the test previously. This study guide seems to really be helping him with the secrets and tools to achieve a higher score.
If you’re considering joining the military, you’ll need to know about the Armed Services Vocational Aptitude Battery, or ASVAB. It’s often given to 11th graders, but anyone joining the military must pass it. It’s used to determine a person’s skills and aptitudes in a variety of subjects, and the results enable the military to place the person in the best possible slot for a person with that particular skill set.
The vast majority of ASVAB test takers will ultimately not enlist in the military. The ASVAB Career Exploration Program claims that only two-and-a-half percent of those who participate in the ASVAB join the military. Forty-seven percent of those who take the exam indicate an interest in attending a four-year college, and 16 percent of those who take the exam originally indicate some kind of an interest in joining the military.
The verbal expression (VE) part of the ASVAB is really important. It factors in to not only your AFQT score, but your Line Score. Line Scores are what determine your job qualifications. Your VE score is computed using adding your Word Knowledge (WK) raw score to the Paragraph Comprehension (PC) raw score. It is then converted to a scaled score ranging from 20 to 62.
A whopping 91% of the reviewers of this ASVAB study guide on Amazon gave it five stars. The other 9%? Four stars. If you can’t trust Amazon reviewers, who can you trust? The beauty of this simply titled study guide is in the depth of explanations in how the answers are derived, particularly in the mathematics sections where the authors go to great lengths to illustrate the more complex 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.
Both you and your counselor will receive a copy of the results. Before you take the ASVAB, you will be asked to sign a statement authorizing the Department of Defense to score your test and return your results to your school. Each school determines if it will release your scores to the military services. If you are a junior, a senior, or a postsecondary school student, a recruiter may contact you. This can occur whether or not you take the ASVAB.

One main shortcoming of this preparation guide is that there are some errors and misprints in the question and answer section. It may be confusing when you think that you got an answer correct but the answer section says that you got it incorrect. This sometimes wastes your time because you go through the question multiple times but then in the end you figure out that you were right all along, but were confused because of the wrong answer given.  Although with this one imperfection, Kaplan ASVAB Premier has many strengths that make it our best value and best overall pick on our list of the top rated prep guides.

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.

A capacitor stores an electric charge using two parallel plates with a a nonconducting material (dielectric) between them.  Capacitors can provide a fixed or variable capacitance in a circuit.  Capacitance is measured in farads (F) and depends on the surface area of the plates (larger means higher capacitance), their distance apart (closer means higher capacitance), and the type of dielectric.

When adding or subtracting signed numbers with the same sign, the answer will always have the sign of the two numbers.  When the signs are different, subtract the smaller number from the larger number and give the answer the sign of the larger number.  When multiplying and dividing signed numbers, the answer will be negative if one of the numbers is negative and positive if the signs are the same.
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.

For the Air Force, Army, Marine Corps, and Navy a retest will only be authorized if a recruit's test scores expire, their scores are too low, if the recruiter feels your scores do not match your qualifications, or in the event of special circumstances that bar a recruit from taking the test. A retest will not be authorized to simply increase an already successful score in order to qualify for particular occupations or for enlistment bonuses. Usually, recruits with successful scores holding a job reservation or who are enrolled in the Delay Entry Program (DEP) are not eligible to retest.


After adding so much information to the aptitude test, there was a bit of difficulty interpreting the test results. In addition to that, a vast majority of test takers were deemed as being under qualified based on their test results. This is why the percentile change was made. It ensured that a 50% actually correlated with a person doing better than 50% of the test takers. Those revisions have worked hand-in-hand with the preparation of the armed forces.
