If you're thinking about joining the U.S. military, your Armed Forces Qualification Test (AFQT) score may well be the most important score you achieve on any military test. You need a qualifying score on the AFQT, or your plans for enlistment come to a dead end — and each branch of the military has its own minimum AFQT score requirements.

If you're thinking about joining the U.S. military, your Armed Forces Qualification Test (AFQT) score may well be the most important score you achieve on any military test. You need a qualifying score on the AFQT, or your plans for enlistment come to a dead end — and each branch of the military has its own minimum AFQT score requirements.
Many of the algebra and geometry questions on the ASVAB AFQT require you to plumb the depths of your memory for a specific mathematical formula. If you can't remember it, you're going to have a tough time coming up with the right answer.In the following practice exercise, you need to match each type of problem with the appropriate formula to solve it.
To enlist in the U.S. military, you have to take the Armed Services Vocational Aptitude Test (ASVAB). The ASVAB consists of nine separately timed subtests, which are primarily used by the military to determine your aptitude to learn various military jobs.Four of the ASVAB subtests are used to compute the Armed Forces Qualification Test (AFQT) score, a percentile score that runs from 1 to 99.
What's the best way to improve your knowledge of suffixes for the Word Knowledge subtest of the ASVAB AFQT? Practice, practice, and more practice. And you can start with the following vocabulary exercise. Practice exercise The following chart contains eight vocabulary words with suffixes tacked on their back ends.
A prefix is a group of letters added before a word or base to alter the base's meaning and form a new word. On the Word Knowledge subtest of the ASVAB AFQT, you'll need to be good at parsing prefixes; the following vocabulary exercise will give you an idea of how much extra prep you'll need before test day. Practice exercise The following chart has eight vocabulary words that have prefixes attached.
A root is a word part that serves as the base of a word. If you recognize a root, you can generally get an idea of what the word means, even if you're not familiar with it.The Word Knowledge subtest of the ASVAB AFQT will test your knowledge of root words, so if you're unsure, the following vocabulary exercises will help you find out beforehand whether you should do some extra prep.
Two of the four subtests that make up your AFQT score are math tests. The first, Arithmetic Reasoning, tests your ability to use mathematics to solve various problems that you may encounter in real life — in other words, math word problems. The second, Mathematics Knowledge, tests your ability to solve general math problems.
When preparing for the ASVAB AFQT, you may benefit by changing the way you study. First, ask yourself the following question: "Do I learn more quickly by hearing something, seeing something, or doing something."If you learn better by hearing, you are an auditory learner; if you learn better by seeing, you are a visual learner; and if you learn better by doing, you are a tactile learner.
The Word Knowledge subtest of the ASVAB AFQT will contain some questions that ask you to define an underlined word in a sentence. Even if you don't know the word's meaning, you should be able to figure it out based on its context within the sentence. If you're unsure about your context skills, try the following practice exercise to test them.
Dividing decimals without a calculator can be a challenge, but it's necessary on the ASVAB AFQT. When you divide decimals, you have to use both subtraction and multiplication. You also need to be pretty good at rounding and estimating numbers. Don't worry, though. You can divide decimals in one of two ways: long division and conversion.
The least common multiple (LCM) of two or more numbers is the smallest number (not zero) that's a multiple of both or all the numbers. Finding the LCM is a useful technique for solving many problems on the ASVAB AFQT math subtests—especially those involving fractions.One way to find the LCM is to list the multiples of each number, one at a time, until you find the smallest multiple that's common to all the numbers.
Anything that saves you time and brain power on the ASVAB AFQT Mathematics Knowledge subtest is useful for two reasons: first, because you're working on a limited time budget, and second, because you can't use a calculator. That's where math properties, like the commutative and associative properties, can help.
When you're studying for the ASVAB AFQT, it can be easy to get distracted. Commercials, the Internet, friends, TV — so many things constantly demand your attention, and they can all feel easier to attend to than study.So what can you do to keep your focus and stay motivated? The following guidelines should help: Give your study the attention it deserves.
You are likely to encounter a question on an ASVAB AFQT math subtest that asks you to multiply decimals together. The best way to get the right answer is through the following three-step process: Convert the decimals to whole numbers by moving the decimal points to the right, remembering to count how many spaces you move each decimal point.
In mathematics, just like in the military, order of operations is very important. On the ASVAB AFQT, every time you tackle a math equation, you'll need to follow the correct order of operations or you may not get the right answer. If you have trouble remembering the correct order, think of the acronym 'PEMDAS': Parentheses, Exponents, Multiplication, Division, Addition, Subtraction.
Simplifying (or reducing) fractions means to make the fraction as simple as possible. You're usually required to simplify fractions on the ASVAB AFQT math subtests before you can select the correct answer.For example, if you worked out a problem and the answer was 4/8, the correct answer choice on the math subtest would probably be 1/2, which is the simplest equivalent to 4/8.
Quadratic equations on the ASVAB AFQT can often be solved with the square-root method (when they're simple) or the factoring method (as long as a = 1 in the form, ax2 + bx + c = 0).But what if they're more complicated? And what if you try to use the factoring method, but you find that a doesn't equal 1, or that you can't easily find two numbers that multiply to c and add up to b?
If you encounter a quadratic equation on an ASVAB AFQT math subtest, don't panic: you may be able to solve it by simply putting the equation into the quadratic form and then factoring.The quadratic form is ax2 + bx + c = 0, where a, b, and c are just numbers. All quadratic equations can be expressed in this form, as in the following examples.
Some math questions on the ASVAB AFQT may involve simple quadratic equations. These are quadratics that consist of just one squared term and a number, and they can be solved by using the square-root rule:Remember that the exponent in a quadratic is never higher than 2 (because it would then no longer be the square of an unknown but a cube or something else).
When you take the ASVAB AFQT, you'll encounter plenty of equations and inequalities. Fortunately, the test proctor will provide an unlimited supply of scratch paper to help you work through them.Simple errors in an equation or inequality can throw off your entire game; the following practice exercise will show you whether you need more practice in this area before the big day.
Some problems on the ASVAB AFQT involve working with percentages, such as discount savings, pay raises, and so on. You often see these problems on the Arithmetic Reasoning subtest, and they're relatively simple to solve.Here's an example: Jamie makes $8.95 per hour. He's such a good worker that his boss gives him a 25 percent raise.
Some math problems on the ASVAB AFQT will require you to apply formulas to solve real-world problems. It's important to not only be familiar with these formulas, but also to know when and how to apply them. Practice exercise In the following practice exercise, you need to match the word problem to the appropriate formula.
Flashcards have been around for a long time. They're still in wide use in these days of electronics and computers because they work. For example, if you need to memorize definitions for the Word Knowledge Subtest of the ASVAB AFQT, flashcards are a great way to help you find, and fix, your vocabulary weaknesses.
