Frequently asked questions
Straight answers about the NAFI CFEI exam, the questions, pricing, the free trial, and how this fits your prep.
The NAFI CFEI exam spans 2 domains - NFPA 921 Guide for Fire and Explosion Investigations, and NFPA 1033 Standard for Professional Qualifications for Fire Investigator. Every practice question maps to one of them, so you train on exactly what's tested.
No - and that matters. These are original practice questions written to mirror the style, difficulty, and domain coverage of the NAFI CFEI exam blueprint. We never distribute actual exam content, so practicing here keeps you fully compliant with official exam policies.
No. NAFI CFEI Exam Prep is an independent study resource for Certified Fire and Explosion Investigator (NAFI CFEI). It is not affiliated with, sponsored by, or endorsed by the official certifying body or exam administrator.
Every paid plan unlocks the full bank of 1,000+ practice questions covering all 2 NAFI CFEI domains - NFPA 921 Guide for Fire and Explosion Investigations, and NFPA 1033 Standard for Professional Qualifications for Fire Investigator. You can practice the whole bank, filter by domain, or run a timed, domain-balanced exam simulation.
Yes - the bank is maintained against the current exam outline, and questions are revised when the exam changes.
No honest practice platform can guarantee a pass. What realistic practice does is show you - before exam day - exactly which domains are weak, and give you the repetitions to fix them. That's the difference between hoping you're ready and knowing where you stand.
Yes. You get 10 free sample questions with instant feedback - no credit card and no account required.
The free sample shows you the question quality. Paid plans unlock the full 1,000+ question bank, exam-style practice modes, mistake review, and - on Fast Track and Pass Confidence - progress analytics that show your readiness by domain.
No. Every plan is a single one-time payment for a fixed access window - 48 hours, 7 days, or 6 weeks. There is no auto-renewal and no recurring billing.
Match it to your exam date: Final Review (2 days) for an exam in the next day or two, Fast Track (7 days) for an exam this week, Pass Confidence (6 weeks) for a structured run-up.
For most countries, the price you see is exactly what you pay - tax is already included. Where local law requires it to be added separately, it's shown clearly at checkout before you pay, so there are never any surprise fees.
Access is instant after payment and runs for your plan's full window from that moment. When the window ends, your local progress stays on your device - you can buy another window any time and pick up where you left off.
Yes - the whole platform is mobile-first: practice, mistake review, and analytics all work on any phone, tablet, or laptop with a browser. Nothing to install.
Every answer feeds your per-domain accuracy, readiness score, and weak-area list. Instead of re-reading everything, you drill the domains that are actually costing you points - that's what moves a score in days, not months.
Chat with us any time - the 24/7 support chat in the corner of every page gives instant answers about plans, access, and billing. Prefer email? The contact link is in the footer. Payments are processed securely by Polar, and active customers can download an invoice from their profile page.
Make sure you're signed in with the same email you used at checkout - access activates within a minute of payment. If it still doesn't appear, email us from the contact link in the footer and it'll be sorted out.

Real feedback from NAFI CFEI candidates on Reddit.
"wasnt sure the practice questions would be close enough to the real thing but they were pretty spot on. the way origin and cause stuff kept showing up in different formats made it stick. passed first try, which honestly surprised me."
"i put off studying for way longer than i should have and ended up cramming the last two weeks on fireexplosionexam.com. the thing that actually helped was going back through missed questions and reading why the wrong answers were wrong, not just memorizing the right ones."
"skeptical at first tbh. ended up using it the month before my exam mostly for the full mock exams. pacing was my problem and running through a timed full-length a few times fixed that. passed. nothing dramatic, just worked."
