- Full-length timed mocks at the real NICET counts and limits
- 20 study notes written for working techs, not a classroom
- Search the notes and bookmark what you return to
- 89-term glossary and 20-entry formula sheet
- 15 field calculators, agent quantity to friction loss
- Every question carries an explanation and code reference
- Works fully offline, no account or signal needed

MOCK EXAMS AT THE REAL SPECIFICATION

Level I is 83 questions in 140 minutes, Level II 144 in 170, Level III 94 in 200, Level IV 63 in 140. NICET updated these exams effective 2 November 2026, moving Level I to 86, so both Level I forms are here — sit whichever matches your test date. Papers are drawn across all twelve areas in proportion, not at random from whichever topic has the most.

KEEPS YOU ON PACE

Set your test date; the home screen counts down, tracks a daily goal and keeps a streak. Readiness is scored per level from coverage and accuracy together, so twenty easy questions answered perfectly will not inflate it. Your weakest area gets a one-tap drill and your misses replay as their own session.

SUBJECT AREAS

Fundamentals and codes. Clean agent, NFPA 2001. Carbon dioxide, NFPA 12. Dry chemical, NFPA 17. Wet chemical and kitchen, NFPA 17A and 96. Foam, NFPA 11 and 16. Water mist, NFPA 750. Pre-action, deluge and water spray. Detection and releasing, NFPA 72. Calculations and hydraulics. Inspection, testing and maintenance. Safety and work practices.

BUILT AROUND THE CALCULATIONS

Agent quantity for halocarbon and inert gas, altitude correction, CO2 volume and material conversion factors, concentration from a cylinder, enclosure vent relief area, foam concentrate, K-factor flow, Hazen-Williams friction loss, pipe velocity, fill volume, density to flow, battery sizing and voltage drop. Each shows its formula and the standard behind it.

FREE AND PAID

All 20 study notes, the glossary, the formulas and all 15 calculators are free, with 25 practice questions in every area and unlimited warm-ups. One optional payment removes ads and opens all 1,000 questions and every full-length mock. No subscription, no account, no data leaving your phone.
