EVT prep built for the real exams — not a generic ASE app.
Every other prep tool treats “EVT” as an afterthought. Overhaul Prep is organized by the actual EVTCC exams you register for — 2,905 Fire Apparatus and Ambulance questions written to NFPA 1900, 1910 and 1917, every answer explained. And because a fire apparatus is a medium/heavy truck, the same subscription covers the full ASE Truck (T-series) certs you already work under — diesel, air brakes, drivetrain, electrical, HVAC — and that Level & Master EVT require. One price, the whole ladder.
Every EVT exam — plus the ASE truck certs your rig runs on
Drill one exam at a time, filter to the high-yield “must-know” items, or take a full-length timed mock. A fire apparatus is a heavy truck, so your EVT prep and your ASE Medium/Heavy Truck prep live in one place.

The Master EVT pathway — all on one subscription
EVT “Level” and “Master” certifications take more than the EVT exams alone — you also have to pass ASE Medium/Heavy Truck exams. Those are in the same subscription, so you study the whole ladder in one place instead of juggling apps and bills.
1EVT exams (EVTCC)
Fire Apparatus F1–F6 and/or Ambulance E0–E4 — 2,905 questions written to NFPA 1900 / 1910 / 1917.
2ASE Medium/Heavy Truck
You're already turning wrenches on a heavy truck — the diesel, air brakes, drivetrain and multiplex electrical under the fire body. The ASE Truck exams (T1, T2, T3, T4, T5, T6, T7, T8, L2) cover exactly that work, and they're the ASE certs Level & Master EVT require. The full bank is included — not an add-on.
3Your certification
Everything the EVT credential your department pays for actually requires — in one place, one subscription, no second app.

EVT questions, answered
Are these the real EVTCC exam questions?
No — EVTCC exam items are confidential and rotate. These are original, high-frequency practice questions written to the same NFPA standards and objectives, each with an explanation. Overhaul Prep is independent and not affiliated with or endorsed by the EVT Certification Commission.
Which EVT exams do you cover?
Fire Apparatus F1–F6 (maintenance & testing, design & performance, fire pumps, electrical, aerials, Allison transmissions) and Ambulance E0–E4 (maintenance & testing, design, electrical, HVAC, cab/chassis/powertrain). More F- and E-series exams are on the way — tell us which you're sitting and we'll prioritize it.
Do you cover the ASE Medium/Heavy Truck certs too?
Yes — the full bank, in the same subscription. A fire apparatus is a heavy truck, so the ASE T-series (T1–T8 plus L2 electronic diesel diagnosis) maps straight to the rig you work on every day — and it's the ASE requirement for Level & Master EVT. No second app, no second bill.
Can my department buy seats for the whole shop?
Yes — one invoice, a seat for every tech, add or drop seats anytime. Set up a shop/fleet plan →
