Light is transmitted via waves of different wavelength and frequency (perceived as color). Light is refracted when it passes from one medium into another and different wavelengths of light bend at different angles.  When light is reflected from a surface the angle at which light strikes the surface is always equal to the angle at which it is reflected.
Paragraph Comprehension tests the ability to obtain information from written material. Students read different types of passages of varying lengths and respond to questions based on information presented in each passage. Concepts include identifying stated and reworded facts, determining a sequence of events, drawing conclusions, identifying main ideas, determining the author's purpose and tone, and identifying style and technique.

There are 65 MEP joint services locations across all 52 states and in Puerto Rico. If you do not live close enough to a MEP, your recruiter will advise you to take the test at one of the MET sites which are located in many Federal government buildings, armories and Reserve stations. With multiple locations across the country to choose from, you won’t have to travel far to take this all-important first step toward a military career.
The sections are as follows, General Science, Arithmetic Reasoning, Word Knowledge, Paragraph Comprehension, Mathematics Knowledge, Electronics Information, Automotive and Shop Information, Mechanical Comprehension, Assembling Objects and a Verbal Expression score influenced by the Word Knowledge and Paragraph Comprehension sections of the test. Those looking to join the Navy also complete a Coding Speed test.
The Marine Corps requires a minimum AFQT score of 32 for those with a high school diploma and a minimum score of 50 for applicants with a GED. As with the Navy, only 5 to 10 percent of each year's Marine Corps recruitment class has a GED. Like the Navy and Army, a minimum score of 50 is required to qualify for incentive programs, including enlistment bonuses, the Marine Corps College Fund and the Geographic Area of Choice Program.

Just as it sounds, in the Paragraph Comprehension subtest of the Armed Services Vocational Aptitude Battery you will be reading paragraphs and then demonstrating your comprehension of those paragraphs by answering questions. This test is part of your Armed Forces Qualification Test score and is also used to determine qualification for a number of military jobs. In other words, this is a very important part of the ASVAB and you should strive to do as good as you can on it. On the paper-and-pencil version of the real ASVAB, you will need to answer 15 questions in 13 minutes when you come to this section. If you take the CAT-ASVAB, you will need to answer 11 questions in 22 minutes in this particular section.
The multiples of a number are the set of numbers formed by multiplying a number by other numbers.  For example, the first five multiples of 3 are {3, 6, 9, 12, 15}.  The least common multiple of two numbers is the smallest number that both numbers factor into evenly.  The first five multiples of of 4 are {4, 8, 12, 16, 20} making the least common multiple of 3 and 4 equal to 12.
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.
The Assembling Objects subtest of the Armed Services Vocational Aptitude Battery is designed to measure your ability for visualizing spatial relationships. In this section of the ASVAB you will be required to view pieces of an object and then determine how those pieces fit together. If you’re asking yourself why this ability is important, the answer is because good spatial skills allow people to figure out maps and interpret graphs and technical drawings. For the Assembling Objects subtest you will 15 minutes to solve 16 problems on the CAT-ASVAB test and 16 minutes to solve 25 questions on the paper version of the ASVAB.
The inverse of an exponent is the root which is indicated by a radical sign √.  A root consists of a radicand which is the number for which you’re finding the root and an index indicating which root you’re finding.  For example, in 3√8 the number 8 is the radicand and the number 3 is the root.  (A radical sign with no specified index is assumed to have an index of 2.)
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.

The food chain describes the interdependency of the various organisms within a community.  The food chain is made up of producers that make their own food and consumers that cannot produce their own food and feed on producers.  Primary consumers feed directly on producers, secondary consumers feed on primary consumers and producers, and tertiary consumers feed on all organisms lower in the food chain.  Also in the food chain are decomposers like bacteria and fungi which break down all members of the food chain to recycle their organic compounds.
A good score on the ASVAB is different than a minimum required score.  Each of the military branches will have their own minimum required scores (see below).  In practice, however, each branch will be more selective in their recruiting.  A score of 50 on the ASVAB implies that you scored as well or better than 50% of comparable test-takers.  Since ASVAB scores are used for many purposes (e.g., enlistment eligibility, military job placements, and career exploration), it is important that you score well on the ASVAB.  A score of 60 or better should be your minimum target.
To enlist in the Air Force, which is considered the most restrictive branch of the military when it comes to AFQT scores, you must have a minimum AFQT score of 36 if you have a high school school diploma. If you have a GED, you must score a minimum of 65. Less than1 percent of people who enlist in the Air Force each year have a GED instead of a high school diploma. In rare cases, the Air Force will accept a minimum score of 31, if an applicant has a special skill that the Air Force deems necessary, such as speaking a particular foreign language. Again, like in any branch of the military, your score not only determines your ability to enlist, it also determines your qualification of the various jobs within that branch.

Mathematics Knowledge. This section measures one's knowledge of mathematical principles and concepts. Arithmetic, geometry, and high school level algebra will comprise most of the problems. Knowing how to factor, solve, and simplify algebraic expressions; understanding exponents, absolute values, and systems of equations and solving inequalities will be helpful. You will also encounter words problems. Test takers should know how to solve word problems by creating algebraic equations. See product recommendations for more advice.
If you’re planning on using your scores for military enlistment, you may be hoping to achieve a score that is high enough for a specific signing bonus. While it’s natural to want to do your best, putting extra pressure on yourself can cause unnecessary anxiety. Take a few deep breaths, relax, and remember that taking the test is only part of the entire recruitment process.

It's important to understand the difference between the ASVAB Standard Scores, and the ASVAB AFQT score. Test takers will receive a separate score for each of the nine sections on the ASVAB. These scores are known as Standard Scores. A Standard Score is used to determine how the test taker compares to the "average" 18-23 year old American on that part of the ASVAB. Not long ago, a large number of people in this age group were given the tests, and these results are the benchmark for Standard Scores. Around half the people in this age group will score a 50 or higher, and about 16% will score a 60 or higher. In other words, the scoring is based on a standard bell curve distribution. Standard Scores are very important when it comes to determining which military job a person will be assigned to.

The four most important sections of the test—Word Knowledge, Paragraph Comprehension, Arithmetic Reasoning, and Mathematics Knowledge-make up your Armed Forces Qualifications Test (AFQT) score. Your AFQT score ranges from 0 to 100 and determines if you are able to enlist in the military and which jobs and programs you may qualify for when you are in.

Your success on ASVAB test day depends not only on how many hours you put into preparing, but also on whether you prepared the right way. It’s good to check along the way to see whether your studying is paying off. One of the most effective ways to do this is by taking ASVAB practice tests to evaluate your progress. Practice tests are useful because they show exactly where you need to improve. Every time you take a ASVAB practice test, pay special attention to these three groups of questions:
The minimum AFQT score for enlistment in the Army is 31, regardless of whether you have a high school diploma or a GED. Waivers can be used to lower the minimum score enlistment score to 26, if the current recruiting requirements allow. If you want to qualify for incentive programs like the Army College Fund, college loan repayment and monetary enlistment bonuses, you typically need a minimum score of 50.
Many high schools give students the opportunity to take the ASVAB as part of career exploration. If you chose not to take one in high school, then you will have to schedule a time to take it. You can contact the Armed Forces Recruiting Officer in your area and you can schedule an appointment with a local recruiter from the branch of the military you wish to join.
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. 

In order to perform well on the ASVAB, you should take a practice test to get an idea of what you’ll encounter on the actual test. Also, completing a practice test will help you to feel more at ease on test day. Reading the test instructions and focusing your full attention on each question are both important steps to take. As you work through the test, avoid spending too much time on a single question. The test has a time limit and you don’t want to fall into the trap of running out of time before you arrive at the end of the test. Taking the time to provide thoughtful answers to test questions allows you to offer a clear picture of your skills and capabilities. Earning a high score on the ASVAB may give you more options when it comes to choosing a specialty.

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.

If you are pressed for time, it may be worthwhile to look into future ASVAB test dates in order to plan ahead in case you get a poor score on your upcoming ASVAB test. You can check with your high school counselor or your military recruiter to make sure that you will be eligible to take future tests along with your planned upcoming test date in the event that you get a bad ASVAB score.
There are essentially two options when it comes to preparing for this test. First, a person can attempt to reassess all of the information that they learned over a decade by spending hours compiling information. Secondly, a person can find a specially formatted ASVAB practice test that covers all areas of both the written test and computerized test. Clearly, the best choice is the ASVAB practice test. The question becomes “Where does one find an accurate ASVAB practice test?”
