Thank you for viewing! This is a set of 15 reference books for firefighter and police officer recruitment exams! This set covers all aspects of the exams, from basic academic test preparation to SCOA, essays, and interview preparation! If you are preparing for the civil service exam, or if you are approaching it and want to start preparing early, please consider this set! Feel free to comment if you have any questions! Thank you! * Individual sales are not possible. * I solved the problems on paper and sticky notes, so I didn't write in the main reference books, and they are relatively clean. (Please understand there may be some minor imperfections) * There may be oversights. Please understand that I cannot photograph or describe everything. * Only the reference book attached in the last photo has mnemonic sticky notes on the first page and in the middle. The sticky notes can be easily removed if they get in the way of reading.
