@daddy34 It’s tough out there right now, even for highly educated white people with vast experience in their field. I have a friend with a Masters degree that had to take a job at Home Depot. I myself was unemployed for over a year and wound up taking a position that only pays half of what a person at my level usually makes, and I was lucky to wind up working in my field of expertise since I am not on the position they originally hired me for.
As for the ASVAB, I still say that the hardest part of it is conquering your own fear. The first time I took it, it was in a vocational class that had one guy with an IQ of 68; he was clinically retarded and yet he did well enough to pass. He had an amazingly high score on the Mechanical Aptitude section too; he beat most of the rest of the class on that part!
Just relax. The harder you try, the more nervous you’ll get, and that is when you will give wrong answers. Don’t be nervous :)
