FN practice questions - frequently asked questions

Plain answers about how FN Exam Prep works: the exam, the questions, pricing, the free trial, and what you actually get.

No - and you should be wary of any site claiming otherwise. Every question here is original, written to mirror the style, difficulty, and judgment the real FN exam tests. Each one comes with a plain-language explanation of why the right answer is right and the others aren't.

The FN exam spans 7 domains: Occupancies Identification (24% of the exam); General Component Requirements (5% of the exam); Booths, Hoods, Ventilation, and Exhaust Systems (14% of the exam); Administration and Records (9% of the exam); Installations (14% of the exam); Inspection (4% of the exam); Maintenance and Recharge (30% of the exam). Every practice question on this site is tagged to one of these domains.

The domains are not weighted equally on the exam. By share of the marks: Maintenance and Recharge 30%; Occupancies Identification 24%; Booths, Hoods, Ventilation, and Exhaust Systems 14%; Installations 14%; Administration and Records 9%; General Component Requirements 5%; Inspection 4%.

The FN exam has 80 questions and is completed in 2 hours. Our timed practice mirrors that length and pacing, so exam day feels familiar.
