Book excerpt: Master the Firefighter Exam: Five Practice Tests consists of five full-length practice tests. There are three general practice tests, each with the same average number and mix of question types you'll encounter on the actual firefighter exam. These practice tests include reading comprehension, reasoning and judgment, spatial orientation, observation and memory, and mechanical reasoning questions and answer explanations. In addition, there is one New York City Exam and one National Firefighter Selection Inventory (NFSI). Peterson's Master the Firefighter Exam shows readers what to expect on their written firefighter exam and helps them understand the subjects covered.
