Questions

Are these the real exam questions?

No — ASE, EVT and EPA exam items are confidential and rotate. These are original, high-frequency practice questions written to the same objectives and formats, each with an explanation.

Do you cover the EVT fire & ambulance certification?

Yes — it's what we're built around. Practice for 19 EVTCC tests — Fire Apparatus (F1–F8, FA4, GL, DO1), Ambulance (E0–E4) and ARFF (A1–A3) — written to NFPA 1900 and 1910, the 2024 standards the EVTCC exams are based on, and organized by the actual exam you're sitting. The same subscription also covers the ASE T-series truck exams required for Level & Master EVT. See the EVT track →

Do you cover EV, ADAS and EPA 608/609?

Yes. L3 hybrid/EV, L4 ADAS and xEV high-voltage safety, plus the EPA Section 609 certification for vehicle A/C and Section 608 (Core and Types I–III) for stationary refrigeration — the certifications you need to legally handle refrigerant.

How current is the content?

It reflects current ASE task lists (including the newer ADAS and hybrid/EV certs), EPA Section 608 and 609 rules, and NFPA / KKK-A-1822 standards — including the 2024 NFPA 1900 consolidation. The bank is re-checked against its sources on an ongoing basis, and answer keys and explanations are corrected when a check or a tech's report turns up a problem.

Can I use it on my phone?

Yes — and it installs like an app. Your progress syncs to your account, so you can drill a few questions on your phone between jobs and pick up right where you left off on the laptop at home.

What if I want to cancel?

Cancel anytime from your account in one click. The 24-hour free trial takes no card, so it never turns into a charge on its own: you only pay if you pick a plan.
