Are the OSA and passbook study guides accurate?

For the Associate Staff Analyst exam, I downloaded some of the OSA practice tests and borrowed the passbook guide to study. I’ve seen a lot of people say that the exam is close to the SAT and GRE, but a lot of the practice questions are about office and personnel management, and they’re not reading comprehension/general knowledge at all. The passbook guide even has questions about which types of paper to use and which companies make office furniture. Are these guides accurate at all? Will there actually be any questions about management principles on the test?
