Everything added to Overhaul Prep in the last 21 days, newest first, with a link straight to each one. Most of it is free to try: the practice tests, guides and task lists are open to everyone, and the app has a free trial.
A guide that starts from the symptom: won't prime, loses prime at draft, short on capacity or pressure, transfer valve won't shift, relief valve or governor won't hold, won't shift into pump, overheating, packing leaks and cavitation. Each one lists the likely causes in the order to check them, how to tell them apart and the fix, from NFPA 1910 and the Hale, Waterous and Darley manuals. Prints cleanly for the bay.
Open the guide →Single-stage and two-stage, split-shaft midship and PTO-driven, front and rear mount, pump-and-roll and separate-engine pumps: how each is driven and engaged, and what that changes when you service and test it.
Open the guide →Every ASE, EPA, Cummins and Detroit practice page now has its own free 10-question test, with the answers and explanations, like the EVT pages. No account needed.
Pick a test →One search across NFPA 1910 and the DOT annual inspection: ask it "minimum brake lining" or "seat belt webbing" and it finds the rule. Plus a brake and tire check against the DOT limits, and calculators for voltage drop, unit conversions and refrigerant pressure-temperature.
Try it free →DOT annual inspection, NFPA 1910 aerial ladder, elevating platform and water tower forms: mark each item, make the call, and email yourself a signed PDF report.
Try it free →Home now tracks ASE Master status as well as EVT: Automobile, Medium/Heavy Truck, School Bus, Transit Bus and Collision, with the tests each one needs, from ASE's own study guides.
Try it free →Start your readiness score fresh, on every device, from the account menu (your name, top right). It clears your answers, scores and streak, and keeps your saved questions and booked exams.
Try it free →The tests you're studying come first, the rest fold away, and "how readiness works" is one tap down instead of in the way.
Try it free →727 questions for diesel students on ASE's five Entry-Level Medium/Heavy Truck tests (diesel engines, electrical, brakes, suspension and steering, and inspection and maintenance), written to ASE's own Entry-Level task lists, with study notes under every task.
See the Entry-Level tests →Core and Types I, II and III, on EPA's own list of test topics. Every question ends with the regulation section it rests on, so you can look it up.
See EPA 608 →ASE's own task list for every ASE test we cover, laid out area by area, with a short study note under each task written from the same checked questions you practice.
Open the task lists →The bank grew from about 14,000 to 19,209 questions: almost every ASE task now has two or more questions, ASE's task lists are covered item by item, and the new tests above came in.
See all the tests →Light Duty, Heavy Duty, EVT, Collision and EPA, in the app and on the practice tests page, so a fire apparatus tech doesn't scroll past every car test.
See the sections →Record an annual pump service test as you run it. The app flags any reading outside NFPA 1910 with its clause, you make the pass or fail call, and you email yourself a PDF worksheet.
See the form →Open any EVT test for a 25-question run in 40 minutes, the length of EVTCC's recertification exams.
Try it free →Once you've studied an EVT test, Home shows which tests each EVT level needs, ticks them off as you log a pass, and suggests the next one.
Try it free →Taking a break between exams? Pause your subscription from your account page instead of cancelling, and switch a monthly plan to yearly to save.
Your account →Timed ASE exams now run each test's real length and clock, from ASE's 2026 study guides: T2 is 65 questions in 90 minutes, for example.
Try it free →A free 10-question test for every one of the 19 EVTCC exams, with the answers and explanations, plus a mixed EVT test. No account needed.
Take a free EVT test →Each EVT test's menu has Study notes beside Practice, Timed and Cram: EVTCC's objectives with a short note under each, checked against the 2024 NFPA 1900 and 1910.
Try it free →Every EVT test's cram set is now built from EVTCC's objective sheet for that test: every area covered, about a quarter of the test, nothing off the sheet.
Try it free →Readiness is now a cautious estimate of how you'd do on the real test. It weighs your latest answers most, counts questions you haven't seen yet at a careful rate, and shows the low end of the range, so it climbs as you cover more of the test.
Try it free →Think an answer is wrong? Report it from the question itself. Reports are checked and fixed, usually the same day.
