Very helpful and has good tests. The actual ASVAB is easier, which is a good thing. Prepare and practice with harder tests and a study guide like this, and you will do well. Just give yourself plenty of time to study. Ideally at least a week at minimum. If I recall I practiced with this for 2 weeks. I scored 93 on AFQT. I was quite a few years removed from high school too, so I had to relearn some of this stuff. Others, I learned for the first time.

I normally don't care to do this, but I kind of felt like I had to with the number of errors in this book. I was actually liking the way it was setup and the tests and everything. I did find an error or two, which I shrugged off, most books have them. I keep reading, to find more and more and more. The thing is these weren't spelling errors. In fact, I didn't find one spelling error in my studies with this book. They were all information type errors. I can remember at least six off the top of my head. For example, in one single paragraph you are told invertebrates have no spine while vertebrates have no spine...yeah it caught me off guard too. One example from the math section, i forget which one, tells you (correctly) that you need to put your answer under the tens place when finding the product of, say, ten times twenty after you have multiplied the first number. It would look something like this: (did my best with the formatting)

This paper-and-pencil version of the test is the same as the paper-and-pencil enlistment version but excludes the Assembling Objects section. It is intended to help those students considering a career in the military to discover their strengths in both military and civilian jobs. If the student scores high enough in the AFQT section of the test, he may use the score to enlist within the two-year expiration window.

Use this book as a guide especially for the word knowledge portion of the asvab, it has a great primer on understanding words that may be unknown to you without having to use a dictionary. The material in the math section of this book however didn't cover what was on the actual exam at Ft. Meade in the testing center. The actual test had many more basic arithmetic reasoning questions rather than algebraic questions involving formulas, coordinates, or inequalities. I think you'll purchase this book and realize that you know more than you think you do. Got a 92 btw on the ASVAB AFQT. Overall this book really helped with word knowledge.

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.

The SAT requires training of the mind. More specifically it requires one to be able to pick up on context clues, make valid assumptions, and express concrete facts. This is why millions of students study intensely before they jump right into the test. Imagine if another area was added onto that same test. The person studying for that test would then need to study even harder. That is the logic that should be put forth when preparing for the ASVAB. It requires that a person expresses the previously mentioned skills while adding the verbal/physical aspects. The question becomes “How does one prepare themselves for this rigorous test?”
