FSD practice questions - frequently asked questions

Plain answers about how FSD 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 FSD exam tests. Each one comes with a plain-language explanation of why the right answer is right and the others aren't.

The FSD exam spans 9 domains: Plans and Specifications (10% of the exam); Guiding Documents (12% of the exam); Features and Components of Fire Dampers (9% of the exam); Features and Components of Smoke Dampers (9% of the exam); Features and Components of Combination Fire/Smoke Dampers (9% of the exam); Features and Components of Ceiling (Radiation) Dampers (7% of the exam); Installation Methods of Dampers (17% of the exam); Damper Inspection (21% of the exam); Safe Working Practices (6% 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: Damper Inspection 21%; Installation Methods of Dampers 17%; Guiding Documents 12%; Plans and Specifications 10%; Features and Components of Fire Dampers 9%; Features and Components of Smoke Dampers 9%; Features and Components of Combination Fire/Smoke Dampers 9%; Features and Components of Ceiling (Radiation) Dampers 7%; Safe Working Practices 6%.
