Go to like a local bookstore like Borders or Barnes and Noble they should have a study guide in stock for the ASVAB, its a pretty thick book but you can probably skim through it and at least know what's gonna be on the test and the instructions for the different sections, which helps to save time.

AND ENDEAVORS TO LIVE THE LIFE WHICH HE HAS IMAGINED, HE WILL MEET WITH A SUCCESS UNEXPECTED IN COMMON HOURS."
