ASE A9 practice questions - frequently asked questions

Plain answers about how ASE A9 Exam Prep works: the exam, the questions, pricing, the free trial, and what you actually get.

No - and you should be wary of any site claiming otherwise. Every question here is original, written to mirror the style, difficulty, and judgment the real ASE A9 exam tests. Each one comes with a plain-language explanation of why the right answer is right and the others aren't.

The ASE A9 exam spans 6 domains: General Diagnosis (18% of the exam); Cylinder Head and Valve Train Diagnosis and Repair (10% of the exam); Engine Block Diagnosis and Repair (10% of the exam); Lubrication and Cooling Systems Diagnosis and Repair (12% of the exam); Air Induction and Exhaust Systems Diagnosis and Repair (24% of the exam); Fuel System Diagnosis and Repair (26% of the exam). Every practice question on this site is tagged to one of these domains.

The domains are not weighted equally on the exam. By share of the marks: Fuel System Diagnosis and Repair 26%; Air Induction and Exhaust Systems Diagnosis and Repair 24%; General Diagnosis 18%; Lubrication and Cooling Systems Diagnosis and Repair 12%; Cylinder Head and Valve Train Diagnosis and Repair 10%; Engine Block Diagnosis and Repair 10%.
