About
Build diagnostic judgment. Practice with purpose. Prepare for A1–A9.
ASE Prep Companion provides independent Automobile & Light Truck preparation across nine sections, from Engine Repair to Light Vehicle Diesel Engines. Study offline with 2,700 original practice questions, explanations, and 45 original diagrams.
• Choose a certification and practice with adaptive, unseen, missed, saved, content-area, and task filters.
• Build a daily habit with five-question drills or mixed drills from your selected certifications.
• Practice pacing with two reserved forms per section: 18 full simulations in total. Each includes ten simulated research items excluded from the scored result.
• Navigate backward, flag items, review answers, and confirm submission. Timed sessions keep their deadline when you leave the app.
• Track study coverage and history independently for each section. Repeat-form results are identified.
• Set target dates and preparation goals for individual sections or the A1–A8 Master Automobile pathway. A9 provides additional diesel preparation.
• Keep progress on your device with native durable saves and recovery from a verified backup.
• Open official and technical references when online. Questions and diagrams remain available offline.
The app is free and includes advertisements. Ads are placed away from active questions and diagrams; completion ads may appear at natural session breaks. Ad privacy choices are available when required.
These are original preparation questions, not actual ASE examination questions. Practice results describe performance within this app and do not predict or guarantee certification. ASE certification also requires qualifying work experience. Credentials entered in the app are self-reported.
