EVT prep built for the EVTCC exams, test by test — not a generic ASE app.
Overhaul Prep is organized by the actual EVTCC exams you register for — 4,967 Fire Apparatus, Ambulance and ARFF questions across 19 EVT tests, written to NFPA 1900 and 1910 (the 2024 standards that replaced 1901, 1911 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)
The F-series (fire apparatus), E-series (ambulance) or A-series (ARFF) tests for your level — 4,967 questions across 19 EVT tests, written to NFPA 1900 and 1910.
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.
Why EVT techs pick Overhaul Prep
Organized by the real exam
All 19 EVTCC exams — F1–F8, FA4, GL and DO1, E0–E4, and ARFF A-1 to A-3 — each with its own bank, not one generic “EVT” pile.
Written to EVTCC's objectives
Written to the learning objectives on EVTCC's sheet for each exam: over 99% of those objectives have questions on them, and readable study notes walk through them.
Updated for 2024
Written to NFPA 1900 and 1910, the 2024 standards that replaced 1901, 1911 and 1917. Plenty of EVT study material still teaches the old numbers.
Every answer explained
You learn why, not just the letter — and on nearly every question, why each wrong choice is wrong too.
Timed like the real test
Timed exams of up to 100 questions on the two-hour clock EVTCC gives you, a must-know cram set for each exam, and a readiness score that tells you when you're ready.
4,967 EVT questions
Deep enough that every timed exam pulls a fresh set — and the same $19.99/month subscription covers the ASE truck tests Level and Master EVT require.

EVT questions, answered
Are these the real EVTCC exam questions?
No. EVTCC exam items are confidential and rotate. These are original practice questions written to the same NFPA standards and EVTCC learning 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?
19 EVTCC tests. Fire Apparatus: DO1 Driver/Operator Inspection, F1 Maintenance, Inspection & Testing, F2 Design & Performance Standards, F3 Fire Pumps & Accessories, F4 Fire Apparatus Electrical Systems, F5 Aerial Fire Apparatus, F6 Allison Automatic Transmissions, F7 Foam Systems, F8 Hydraulic Systems, FA4 Advanced Electrical Systems, GL Ground Ladder Testing. Ambulance: E0 Maintenance, Inspection & Testing, E1 Ambulance Design & Performance, E2 Ambulance Electrical Systems, E3 Ambulance HVAC, E4 Cab, Chassis & Powertrain. ARFF (airport rescue and fire fighting): AR1, AR2, AR3. Sitting one we don't list? Tell us 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 Level and Master EVT require ASE truck tests alongside the EVT ones. No second app, no second bill.
Can my department buy seats for the whole shop?
Yes. One invoice, a seat for every tech, and you can add or drop seats anytime. Set up a shop/fleet plan →
