For almost a century, the U.S. military has been a pioneer in the field of using aptitude tests to evaluate an individual’s potential for service. The organization also uses the test to determine aptitude for various military occupational specialties (MOS). The use of aptitude tests began during World War I. While the group-administered Army Alpha test measured verbal and numerical ability as well as general knowledge, the Army Beta test was used to evaluate illiterate, unschooled and non-English speaking volunteers and draftees. The Army and Navy General Classifications Tests replaced the Alpha and Beta tests as a means to measure cognitive ability during World War II. The results of these tests, as well as additional classification exams, were used to assign recruits to a particular MOS.

This was an excellent study guide for the ASVAB! I had graduated high school over 7 years ago so being able to brush up on my algebra and geometry was extremely helpful. It was an easy read and with 4 or 5 practice tests I felt prepared when the day to take the test actually came. I wasn't blindsided by any of the questions because the format was so similar to this book.

Muchos subpruebas del ASVAB, como General Ciencia, Comprensión Mecánica, Información Electrónica y automática e Información Shop son difíciles de ace ya que probablemente no aprendió mucho acerca de ellos en la escuela secundaria. Así que es posible que tenga que memorizar hechos e ilustraciones para hacer bien en las áreas de la ASVAB que no están familiarizados. Utilice estos diez métodos de estudio para engañar a tu cerebro a recordar todas las cosas que usted necesita saber para conseguir un resultado excelente en el ASVAB:
I bought this book and ASVAB AVQT for Dummies for my son who was (at the time and now IS) going into the Navy when he graduates this year. I was skeptical at first, wondering if 1. he would actually use them and 2. would they really help him get a better score. He had a VERY high goal score because the particular job he wanted to qualify for required a high score. We were not disappointed. I helped him study, we didn't need flash cards or anything else, just these books! Well, he made the score for the job he wanted. Great books, worth the investment unless you just want to coast (see what I did there?) by and pass. I have to add, I'm so proud of my son! GO NAVY!

I glanced through this book as well as a few others at a book store. This book had four practice tests, whereas most others only had three. I liked that, so I bought it. However, once I started to take the tests and read the review material, I noticed that this book has a deplorable number of mistakes. I DO NOT recommend buying this book unless you are trying to play a cruel joke on someone who is trying to join the military.


The Arithmetic Reasoning section of the test measures your ability to solve arithmetic word problems. You may be asked questions such as “If the tire of a car rotates at a constant speed of 552 times in 1 minute, how many times will the tire rotate in half an hour?” Therefore, reviewing common math key words associated with each operation is recommended. For example, if you see the key words “in all,” the problem deals with addition. If the problem asks you to “find the difference,” you are being asked to subtract. If a question asks “how many times” per day or week, you know you are dealing with multiplication. If it asks “how many in each,” you should be thinking about division. The CAT-ASVAB has 16 questions in 39 minutes; the paper-and-pencil version has 30 questions in 36 minutes.
Now, one page over while showing how to multiply decimals, which is the same thing, they fail to do this and obtain a wrong answer. I'm a laid back guy and all, but I mean come on. That's pathetic. There is more, but this should suffice. After I found quite a few errors like this I just couldn't bring myself trust the other info in the book. I bought "Asvab for Dummies" and have found not one error in it.
The ASVAB is one of the most widely used aptitude tests in the world. The intent of the ASVAB test battery is to assess a candidate's potential for future success in the U.S. Military. Because of the nature of the test, the ASVAB can also be used to give a candidate valuable information about both military and civilian career choices that they may be suited for.
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.

Wow, it changed my whole perspective on what was going to be on the actual test. A lot of the things in the practice test were things I really didn't know, especially in the mechanical and electronics knowledge. Of course, those sections don't exactly count unless you're pursuing a job in those fields, but a lot of the knowledge in the practice tests is very useful. Having not taken a mathematics course for awhile, it was good to retest my abilities on their problems. Whether or not you really want to score high on your ASVAB, I would suggest it just for keeping you sharp.
As a general rule of thumb, anything over an 85 on the ASVAB will qualify you for nearly any position in the armed forces. But there are slight breakdowns within each score. For example, in order to qualify for Surveillance and Communications (SC) in the Army, Word Knowledge, Paragraph Comprehension, Arithmetic Reasoning, Auto & Shop and Mechanical Comprehension all require high marks. Though scoring an 85 or above would guarantee you scored in a high enough percentile to qualify for SC.

The CAT-ASVAB is an adaptive test which means the test adapts to the ability of the test-taker. It is possible to administer a shorter test this way than with the pencil and paper test. When you complete a subsection of the test, you can then move onto the next section of the test without having to wait for an administrator. Subsections are still timed however and on average it takes about 1 ½ hours to complete the computer ASVAB.

Since 1976, the multiple-choice ASVAB has been used for initial aptitude screening as well as MOS classification. The exam has changed since its inception. While some parts have remained, such as arithmetic reasoning and word knowledge, others like tool knowledge have been removed in favor of questions related to assembling objects. After nearly 20 years of research and development, a computer-adaptive version of the exam was implemented in 1996. The CAT-ASVAB is the first large-scale adaptive battery test to be administered in high-stakes environments like a Military Entrance Processing Station. The paper and pencil, or P&P version is still used at a variety of other military testing sites.
