True that. Go with Barrons with the PAT. Also, go to a bookstore, preferrably Barnes & Noble, and look for an ASVAB mechanical and spatial skills book. It has Key Holes, Cubes, Pattern Development, and other perceptual ability aids. It also would not hurt to use you surrounding environment to your advantage. Draw objects in your room from different points of view, assuring to place dotted lines in the right place. Be creative!!! Good luck!
