I live in a small hillbilly town in Texas, and I can walk into the local bookstore and find 10-15 study guides on police exams.
I never used one though because all the exams I've taken thus far, a 3rd grader could have passed. Just bone up on your basic Math and English skills...because that's all that has been on my "civil service exams".
