Perfecting your way to a higher score

Albert Einstein once said, “Do not worry about your problems with mathematics. I assure you mine are far greater.” The good professor obviously never faced an upcoming ASVAB exam! Okay, just kidding. You don’t have to be a mathematical theoretician to score well on the Mathematics Knowledge subtest. This subtest asks questions about basic high school mathematics. No college or graduate degrees needed.

On the paper version of the ASVAB, the Mathematics Knowledge subtest consists of 25 questions, and you have 24 minutes to complete the subtest. The CAT-ASVAB offers 16 questions in 20 minutes. You don’t necessarily have to rush through each calculation, but the pace you need to set doesn’t exactly give you time to daydream. You have to focus and concentrate to solve each problem quickly and accurately. And no calculators allowed!

Most of the time, the Mathematics Knowledge subtest contains only one or two questions testing each specific mathematical concept. For example, one question may ask you to multiply fractions, the next may ask you to solve a mathematical inequality, and the question after that may ask you to find the value of an exponent. (If you’re freaked out by the last sentence, calm down. I cover these concepts in this chapter.) ...
